Unit Overview
COVID-19 & Health Equity, Grades 3-5

How can we make decisions to care for ourselves, our families, and our communities?

Unit Summary

The COVID-19 Pandemic is a clear example of how science and society are connected. This unit explores how different communities are differentially impacted by the virus through the lens of historical inequities in society. In the context of decisions their families make, students explore the basics of how the virus affects people, and design investigations to explore how it spreads from person to person, and what we can do to prevent that spread.

Students explore how some communities are more affected by COVID-19 than others and how this is related to how society has treated some people unfairly for a long time. Students and families consider how scientific knowledge changes as we learn more, and how our decisions may also need to change. Asking “Should we…?” questions helps students and their families to consider the kinds of informed action we can take to care for ourselves and others. This multidisciplinary unit includes integrated social-emotional learning and supports for teachers and families in addressing these emotional topics.

This unit is centered around a current event with rapidly changing data and information. Be aware that this unit was written in August 2020 and revised in March and April 2021. Due to the evolving pandemic situation, our growing knowledge about COVID-19, and availability of effective vaccines, you may need to adjust or update some of the information provided in this unit when you teach it.

Unit Information
How will this unit meet the needs of my specific grade level?

This unit was designed for teachers in grades 3, 4, or 5 by providing the following supports:

  • Specific callouts throughout the teacher guide to suggest when and how to modify activities to meet the needs of students who need more support or students who are ready for more, especially in the areas of literacy, math, and science practices. 
  • A variety of texts and videos for obtaining information about the virus, marked to indicate their complexity so that teachers can choose which will best fit their students’ needs.
  • Family Tools that invite families to share in conversations and activities that will inform class discussions and provide authentic ways for students to reflect on and share their learning.
When in our school day should I teach this unit?

The COVID-19 pandemic has highlighted how science and society connect. Therefore, the content of this unit includes science, social justice, and social-emotional learning, and students use literacy and math skills to explore these ideas. As such, you may see fit to teach this unit during any of those subject times in your schedule, a combination of them, or during other flexible parts of your day. For example, you might start a lesson by discussing the Family Tool responses during SEL circle time, then continue with a researching-to-learn step during your literacy block or carry out an investigation during science or social studies time. Additionally, if you do not have those subjects every day, the lesson parts could be spread over a series of days. We have included icons in the Lesson Snapshot table for each lesson to suggest subject times you might use other than science (social studies, literacy, math, and SEL). Due to space limitations, we did not suggest multiple disciplinary connections for every step in the lesson sequence, so use your judgement to decide how best to make this lesson work for your class and your schedule. We did not include the science flask icon in the Lesson Snapshot table because science practices are used throughout the lessons – the multidisciplinary connections support and enhance the science practices.

This unit consists of 13 lessons which total 21 “days” of 40 minutes each. Additionally, some lessons include “Going Deeper” parts to provide extensions and enrichments to the ideas and practices in that lesson. These Going Deeper activities are indicated with gray rows on each Lesson Snapshot table and the times suggested for them (in parenthesis) will take your class beyond the 40 minute total for that day. However, we anticipate that teachers will use information provided in the Lesson Snapshot table to adjust the parts of each lesson to fit their schedules. Some teachers will plan to use about 40 minutes of their day several days a week to teach this unit. Other teachers may choose to break the “days” into different pieces and include some or all of the Going Deeper steps to fit the needs and interests of their class. 

Just as teachers may be flexible with the amounts of time they use for these lessons each day and during what parts of their day, some teachers may choose to skip activities and/or lessons based on their students’ prior knowledge and experiences. For example, some schools begin the year practicing effective handwashing; it might make sense for those students to skip parts or all of Lesson 7. Some classes do in-depth work around media literacy and credible sources with a library information specialist or in a different social studies unit; it might make sense for those students to skip parts or all of Lesson 3. Each teacher and class can adjust this unit to meet their needs and their schedule.

What are Family Tools?

This COVID-19 & Health Equity Unit contains Family Tools as part of the storyline. These tools are meant to engage children and families in learning more about the COVID-19 disease and the SARS-CoV-2 virus that causes the disease. In addition, these tools are meant to help teachers learn more about families’ knowledges and practices related to SARS-CoV-2 and COVID-19 so that they are better able to support children’s learning. Families have rich knowledges, practices, experiences, identities, and relations that support children’s learning within and across contexts. Family Tools help children and educators explore and use these various dimensions as part of children’s learning in school, and they help support “partnerships for familial and communal thriving and learning across places” (Learning in Places Collaborative, 2020). Family Tools are not meant to be evaluated by classroom teachers or as something to be graded. Rather, they are learning supports for educators, children, and families themselves. Schools often hold deep deficit views of families and make problematic assumptions about families’ commitments, intellectual capabilities, experiences, and interests. Family Tools offer a path toward resisting these problematic assumptions that are often racist, classist, xenophobic, and the like.

Why does this unit include Family Tools?

Family Tools serve several purposes. Family Tools:

  • help expand the practices of creating equitable relationships and community among families, educators, and learners; 
  • ensure that family knowledges, practices, experiences, identities, questions, and wonderings help structure, guide, and facilitate children’s learning in school classrooms; 
  • create supports for children that coordinate their navigation across home and school. These tools support generative intergenerational learning in family and school contexts; 
  • help educators see and expand their understanding of the cultural and intellectual strengths of families, and help educators routinely incorporate family knowledges, practices, experiences, questions, and wonderings into instruction to more robustly support children’s learning; and  
  • model language and ideas that help support children’s learning across family and school contexts.


What types of Family Tools are part of this unit?

In the COVID-19 & Health Equity Unit there are two different types of Family Tools that serve different purposes. 

  1. Pre-Unit Family Tools provide overview information for families about the big ideas and dimensions that are reflected in the unit. They also point to resources that families might choose to explore and questions upon which they can reflect. These tools include:
  • information about the SARS-CoV-2 virus and the COVID-19 disease that it causes, what scientists and other experts recommend people do in order to try and lessen the spread of the virus, and why learning about this is important for present and future decision-making (decisions individuals might make, decisions families might make, and decisions communities might make and why); 
  • issues of equity associated with SARS-CoV-2 and COVID-19, such as systemic racism related to food, housing, and healthcare, that are important for families and children to explore and discuss as part of their ethical deliberations and decision-making; 
  • children’s conceptions of illness and death and why social emotional learning is an important part of children’s learning about COVID-19; and
  • ethical deliberation and decision-making, especially as related to SARS-CoV-2 and COVID-19.
  1. Lesson-Specific Family Tools:
  • help provide a better understanding of families’ ideas, knowledges, practices, questions, and wonderings related to elements of the COVID-19 & Health Equity Unit that children and teachers can use as part of classroom instruction to support children’s learning. For example, prior to or during classroom lessons, families might engage in discussions within their families or with other families, collect information, or participate in an activity. Children then bring those ideas, questions, practices, and wonderings generated by their families to school where children and teachers can use them during instruction and classroom activity; and
  • help summarize classroom activity and discussions for families, and provide an avenue for them to generate additional reflections, questions, and wonderings. After many classroom lessons, families receive information and examples related to what children did in school and are able to reflect on that learning, as well as generate questions and wonderings related to that learning that children can then bring back to school.
How do I support classroom discussions?

Establishing classroom norms, expectations, or agreements to form a strong and safe class culture, especially around discussion, is critical for teaching this unit. You may have students participate in the creation of these norms, or you may wish to create them yourself and then share them with students. If you create the norms yourself, spend time discussing with students why each one is important, what it might look and sound like when students are “demonstrating” the norm, and how not following the norm could affect how others feel and interact with the learning community. Be careful of expectations that have often been normed for whiteness and used to maintain white comfort, such as “be nice.” It is important to make sure the norms in your classroom are not being used to police or silence students who may feel hurt or anger during conversations, particularly Black and/or Latinx students.

If you haven’t already done so in your classroom, plan space for your students to be together for discussions during this unit. Ideally, they would be able to gather in a circle so they can all see each other. Often students will also need to see and interact with a shared space such as a projected screen or chart paper or whiteboard, so a full circle may not always work. If you don’t have room for a circle of students or don’t always have time for them to move furniture to create that space, gather them together in a central location, such as on a rug at the front or back of the classroom. Being together in this way, where everyone is included and can be seen and heard clearly, will support interactive discussions among your students, increasing student agency and access.

In order to support meaningful sensemaking in classroom discussions, the Teacher Guides provide suggested prompts and sample student responses. The prompts are not intended to be a script, but rather a guide to help you support students as they engage in productive talk and science practices. Also, we do not expect that your students will respond to your questions in exactly the same way as is indicated in the sample student responses. Rather, the sample responses are intended as kind of “targets” for you to listen for – when students are saying those things, you do not need to probe deeper and can move the discussion along. When revoicing or clarifying student ideas be mindful to include the language students use and not to push for the suggested responses or a certain way of saying something. For more information about supporting student discussions and productive talk, see the Supporting Discussion section in the OpenSciEd Teacher Handbook (page 38-45).

How do I support students who have been personally impacted by COVID-19?

Work to build relationships with your students so that they know they will not be judged for expressing their emotions. Be sure that you have established classroom norms to build a strong classroom culture within which students feel safe sharing their feelings. Do not minimize or attempt to change these emotions but listen thoughtfully and validate those feelings. We all have strong feelings—it is natural and normal. Identifying those feelings (and why we have them, if possible) helps us build our self-awareness. Model coping strategies you use (see the example in step 2 of Lesson 1). Prepare your students for how to respond if and when classmates mention that someone they know has gotten very ill or died from COVID-19. Remind your students that they should be an active listener (don’t interrupt) when a classmate shares and acknowledge that person’s feelings by saying something like, “Wow, that must have been really hard” or “I’m so sorry that happened.” Also, consider working directly with a school counselor or social worker to provide support for students who have experienced trauma related to COVID-19.

How do I support students who have experienced systemic racism?

Take the time to have foundational discussions about race in your classroom, if you haven’t already. Often, issues of race are avoided because the fact of inequity is uncomfortable to talk about and acknowledge. Think about for whom these conversations are uncomfortable and for whom these conversations are simply a reflection of their lived experience. When we bring issues of racial inequity out into the light, we can use that information to make more ethically responsible decisions. You may wish to begin by reading and discussing some of the books listed here: https://www.embracerace.org/resources/20-picture-books-for-2020 and Learning for Justice has substantial lesson plans available on their website, as well, at https://www.learningforjustice.org/classroom-resources

In this unit, we openly acknowledge examples of systemic racism and how they are contributing to the disproportionate effect of COVID-19 on Black, Indigenous, and people of color communities. We should all feel angry and sad about these inequities, but exploring them could be especially emotional for students who have experienced systemic racism themselves. Encourage students to express their emotions, validating their concerns or frustrations. Continue to use Family Tools to encourage and support discussions of racism in families, asking them to highlight the strengths in families and communities and sharing those strengths in class. As you make action plans for how to care for ourselves, our families, and our communities, understand that racism and inequality work on a systems level that is the result of historic inequalities meant to privilege whiteness—and that, while individuals can make ethical choices and shift systems, change needs to happen at the systems levels. Encourage students in taking classroom-level and wider collective, systemic action.

How do I support students who do not believe that COVID-19 is a public health crisis?

Some students may perceive the COVID-19 virus as not serious, not real, or not a public health emergency. Ensure students that we are examining data and looking at evidence from the science of the COVID-19 pandemic. We will use data to support our thinking about the pandemic. We will use data as evidence that COVID-19 is negatively impacting communities because of historical injustice and systemic racism. We will hear different perspectives and try to consider those perspectives to see what others are experiencing. 

How do I support students who may be hesitant about getting vaccinated for COVID-19?

Your students, like many children, may be anxious about getting a shot. Validate and accept these feelings, and as you investigate how vaccines work and why they’re so helpful, continue to check in on your students’ emotions. 

Read the COVID-19 Vaccines Unit Resource for Families and Teachers for information about how the vaccines were developed and approved, how they work, and what we’re still learning about them. That resource also provides additional information about addressing vaccine hesitancy, but here is some general information: People who have not yet been vaccinated can be generally be grouped into three categories: (1) those who want to get the vaccine but can’t yet (not their turn, not medically eligible, or have barriers to access), (2) those who are hesitant but may decide to get it, and (3) those who have decided certainly not to get it. In this unit, students explore the issues surrounding that first group, and will investigate how limited doses have been prioritized, how barriers have limited access to vaccines, and how it’s important to continue taking other preventative measures to avoid spreading the virus even though we have vaccines now. In regard to vaccine hesitancy, some people understand the benefits of vaccination for COVID-19 but need more information about its cost or safety. However, vaccination is free and you cannot get COVID-19 from the vaccine, the potential side effects are temporary, and serious adverse reactions are very rare. Some people feel like they don’t need to be vaccinated; however the risks of becoming ill with COVID-19 for weeks or much longer, spreading the disease to others, and possible death are a higher toll than the inconvenience of being vaccinated. Finally, some groups of people are hesitant to be vaccinated because discrimination in healthcare–both historical and ongoing– has caused them to distrust the medical/research community. Some such communities, such as some Indigenous communities, have been leaders in developing strategies for building trust among elders and other community members around the vaccine. See the COVID-19 Vaccines Unit Resource for Families and Teachers. for more details and resources about hesitancy and the COVID-19 vaccines. This unit does not address that third group – often people who have already decided against the vaccine deny the science behind it or believe in conspiracy theories about it. Additional resources about vaccine misinformation are linked in the  COVID-19 Vaccines Unit Resource for Families and Teachers.

How do I adapt this unit to my remote learning environment?

This unit was designed so that students could engage with the materials in a classroom setting or at home via remote learning. Callouts in the sidebar of each teacher guide suggest supports for remote learning, including which elements of the lesson would be ideally taught during synchronous time. The unit is written in “days” of 40 minutes each, but each teacher guide includes a “lesson snapshot” chart at the beginning, which summarizes the steps in the lesson; so you may choose to break the “days” into different pieces, many of which could be done asynchronously. The following sections give specific suggestions for setting up components of the unit for remote learning. Recall that many of the artifacts you create as a class (such as the Driving Question Board, Word Wall, and Decision-Making Chart) will be referenced throughout the unit, so you’ll need a way to link back to them or reshare them in your virtual learning environment.

Leading Discussions

Due to privacy concerns and equity issues (such as unreliable internet access), not all students may choose to have their video on during virtual class discussions. Encourage students to join in the conversation via audio only, with no stigma, and invite students to reply to questions using the meeting’s chat feature. Use breakout rooms to allow for small-group or partner talk, posting the discussion prompt(s) in the chat so that everyone can refer to them. 

Collecting Shared Class Ideas

Many lessons call for “chart paper and markers (or similar digital tool)”. Your remote teaching setup may include chart paper, and you can scribe student ideas or create a consensus model as you would in your typical classroom, just on video so that students can see and participate. However, you may also choose to create a shared Google document when collecting student ideas (and you can type into it as students share aloud or give all students editing access and have them each type their ideas into a certain area of the document, such as a table row). Padlet, Jamboard, and Mural are platforms that use digital “sticky notes” and are helpful for times when everyone is contributing ideas (such as for the Driving Question Board).

Student Notebooks

Students will use notebooks as a thinking space to plan ideas before sharing, reflect personally on their feelings, and record data from investigations. These notebooks need not be shared with the teacher (unless you choose to ask for them), so it may work just fine for you to have students at home work in a regular spiral-bound notebook. However, you may also choose to set up digital student notebooks, which could be as simple as a running Google document they type in as needed or as fancy as slides that you’ve prepared for each lesson with locked objects, including prompts and space for students to respond.

Word Wall

Throughout the unit, your class will post important words on the Word Wall (see section that follows for more information). You may choose to post Word Wall words on a physical pin board or write them on chart paper in your own remote teaching space and then put it in view as students need it for reference. You also might create a shared document or slide deck that you add to as the unit goes on. Alternatively, or in addition to your class Word Wall space, students might record Word Wall words in the notebooks as their own personal glossary for the unit. Whatever setup you choose, be sure you can add drawings or pictures so that each word’s definition includes visual support.



The investigations in this unit were designed to use common household items so that students would not need specialized materials if they’re doing investigations at home. That said, you will likely want to plan asynchronous time for students to carry out the investigations because the gathering of those supplies (especially if adult help is required) might not be immediately possible.
