Unit Overview
COVID-19 & Health Equity, High School Science

How can we slow the spread of the COVID-19 virus to protect our communities?*

Unit Summary

This unit is designed to support students in understanding the COVID-19 pandemic, transmission of the COVID-19 virus, and the impacts of the pandemic on communities, especially communities of color. Specific learning targets are listed at the beginning of each lesson and highlight a core idea for the lesson, the science and engineering practice students will engage in, and the crosscutting concept students will use in the lesson. There are four broad areas of learning goals targeted in this unit:

  • virus transmission between people and communities,
  • mitigation strategies and using probabilities to explain how we can lower the chance of transmitting the virus between people and across communities,
  • understanding disproportionate impacts on communities and the policies and practices that lead to those impacts, and finally,
  • development of two social emotional competencies--self awareness and social awareness.

*This is a field test version of the unit and will be revised after the end of the field test and released in March 2021.

What should my students know from earlier grades or units?

This unit builds on previous grade band understanding from middle school in order to support understanding of the COVID-19 pandemic across high school levels from 9th to 12th grade. 

Mathematics 

This unit assumes that students will use the following middle school CCSS math concepts: 

  • CCSS.MATH.CONTENT.6.RP.A.3
    • Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
  • CCSS.MATH.CONTENT.6.RP.A.3.C
    • Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.
  • CCSS.MATH.CONTENT.7.SP.C.7
    • Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.

NGSS Science and Engineering Practices

Students would benefit from having prior experience doing the following science and engineering practices (SEPs) at the middle school grade-band level. They include the following:

  • Developing and using models
    • Develop and/or use a model to predict and/or describe phenomena.
  • Analyzing and interpreting data
    • Use graphical displays (e.g., maps, charts, graphs, and/or tables) of large data sets to identify temporal and spatial relationships. 
    • Apply concepts of statistics and probability (including mean, median, mode, and variability) to analyze and characterize data, using digital tools when feasible. 
    • Analyze and interpret data to determine similarities and differences in findings. 
  • Using mathematics and computational thinking 
    • Apply mathematical concepts and/or processes (such as ratio, rate, percent, basic operations, and simple algebra) to scientific and engineering questions and problems. 
  • Constructing explanations and designing solutions
    • Apply scientific ideas, principles, and/or evidence to construct, revise and/or use an explanation for real world phenomena, examples, or events. 
  • Obtaining, evaluating, and communicating information
    • Critically read scientific texts adapted for classroom use to determine the central ideas and/or obtain scientific and/or technical information to describe patterns in and/or evidence about the natural and designed world(s). 
    • Gather, read, synthesize information from multiple appropriate sources and assess the credibility, accuracy, and possible bias of each publication and methods used, and describe how they are supported or not supported by evidence.  
    • Evaluate data, hypotheses, and/or conclusions in scientific and technical texts in light of competing information or accounts.

NGSS Crosscutting Concepts

Having students familiar with using focal crosscutting concepts (CCCs) for this unit at the middle school grade-band level would be helpful. They include the following:  

  • Patterns
    • Graphs, charts, and images can be used to identify patterns in data.
    • Patterns in rates of change and other numerical relationships can provide information about natural systems.
    • Patterns can be used to identify cause-and-effect relationships.
  • Cause and Effect
    • Cause and effect relationships may be used to predict phenomena in natural or designed systems. 
    • Phenomena may have more than one cause, and some cause and effect relationships in systems can only be described using probability. 
  • Scale, Proportion, and Quantity
    • Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small. 
    •  Proportional relationships (e.g., speed as the ratio of distance traveled to time taken) among different types of quantities provide information about the magnitude of properties and processes.
Unit Information
How do I support students who have been impacted by the COVID-19 virus and systemic racism?

In this unit, students build on their life experiences and previous understandings of the COVID-19 virus. Students will come to the unit with a wide range of background knowledge about symptoms and some students will have been more directly impacted than others by the COVID-19 virus in their families or communities. Some students will have experienced watching friends or family members with COVID-19, or may have been sick themselves. Some students may have been to funerals or experienced personal losses from COVID-19. As we discuss in the unit, People of Color have been disproportionately impacted by the COVID-19 virus, and for some students of color, systemic racism will be in the front of their mind as they watch the discrepancies between the impact on their own communities versus those of their White peers. During this lesson, acknowledge that this topic may be really difficult for some students. Remind students that emotions are real and that it’s okay to feel angry, sad, scared, and a myriad of other feelings.  Identifying how we feel is one of the best tools we can use to feel regulated.  Demonstrate for students that when you feel your heart rate elevate, a pain in your gut, or a tingle up your spine, you can say to yourself, “this is me feeling angry, and my anger is valid.” Let students know that if they need to take a step outside the room or take a moment to themselves to breathe and feel their emotions, that’s always okay. If students would like to write about how they are feeling, call a family member, or speak with a school counselor, support them in doing so. Teachers modeling coping strategies can support students’ social and emotional development. 

How do I support students who do not believe the COVID-19 pandemic is a public health emergency?

Some students may perceive the COVID-19 virus as not serious, not real, or not a public health emergency. The disconnect between students’ beliefs and science may cause discomfort in class. Ensure students that in this class we are examining data and looking at evidence from the science of the COVID-19 pandemic. We will use the data to ground every conclusion we draw about the pandemic and we will look closely at communities that have been greatly impacted by the COVID-19 pandemic. We will hear different perspectives from people and try to take on those perspectives to see what others are experiencing. Remind students to support their ideas with evidence and data from science.

How do I support classroom discussions?

It is unlikely that this will be the first unit of the school year and when you use this unit, you and your class will have established community norms. Before you start this unit, it may be productive to revisit your community norms and update them by asking students what they want to add to the list. This is important because the unit will bring up difficult and emotional discussions and topics for everyone, and topics about which students may differ in their beliefs. We want to note that norms and norming activities are tricky. They can be important and helpful for having classroom discussion. Norms such as “be nice” or “be kind” are often normed for whiteness and can be used to maintain White comfort. It will be important to make sure norms in your classroom are not being used to police or silence students who may feel hurt or angry during conversations, particularly Black and Hispanic/Latinx students. This is important because we will be talking about structural inequalities and racism during the unit.

How do I customize language around race and ethnicity to fit within my local context?

In this unit, we refer to racial and ethnic groups using the language and terminology that is used in nationwide data reporting in order to match the data we will be looking at in the unit. We also use terms recommended by equity experts, like Indigenous and Latinx. However, local communities and people may prefer different terms to identify themselves. We suggest you take steps to understand the terms used within your community, and then use language that aligns with community-accepted identifying preferences. This may require you to modify some of the terms used on student-facing resources, such as handouts, slides, and readings.

How do I adapt this unit into 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. The unit is written in “days”, each of which is equal to a 45-minute class period. Each lesson includes a “lesson snapshot” at the beginning of the learning plan that summarizes the activities in the lesson and the estimated time. You may choose to break the “days” into different pieces, some of which could be done asynchronously. You may also choose to combine “days” of instruction if you are teaching on a block schedule. 

The following sections provide 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) will be referenced throughout the unit, so you’ll need a way to link back to them or reshare them in your virtual learning space.

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 and post the discussion prompt(s) in the chat so everyone can refer to them. 

Collecting Shared Class Ideas

Many lessons call for “chart paper and markers”. 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 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 thinking space to plan ideas before sharing, keep track of their work, and reflect personally on their feelings. 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 use a regular spiral-bound notebook to work in. 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.

What does it mean that this is a field test unit?

This is a field test version of this unit, which means that it has not yet been reviewed or tested sufficiently to determine that it meets the standards of BSCS Science Learning and OpenSciEd for high quality instructional materials. The developers will be conducting a field test and obtaining reviews in the fall of 2020 and revising the materials for official release in March 2021. Because of the importance and time-sensitive nature of the unit’s subject, the developers have decided to make this version of the unit available to educators while we are reviewing, field testing, and revising it.

Given the unit’s status, the developers encourage educators to review the materials carefully and make an informed judgment about the appropriateness of the unit for use in their context. The developers seek feedback about this unit from both educators who choose to use this version and those who choose not to. All feedback received at http://bit.ly/COVID-Unit-Feedback before December 31, 2020, will be consulted in the process of revising the unit.
