Testing Gait Symmetry with Uneven Loads
Add Favorite
Science Fair Project Idea
Scientific Method
The way humans walk—our gait—is usually fairly symmetrical. Each step we take with the left foot is similar in length and timing to the step with the right foot. This symmetry makes walking efficient and reduces stress on the muscles and joints. But what happens when the body is challenged by an uneven load, such as carrying groceries in one hand or holding a backpack on one shoulder? Biomechanics research shows that unequal weight distribution can disrupt gait symmetry, forcing one… Read more
What’s Your Ideal Walking Speed?
Add Favorite
Science Fair Project Idea
Scientific Method
​​Walking may seem simple, but it is actually a carefully coordinated process involving balance, rhythm, and efficiency. The way we walk—our gait—changes depending on speed. At slower speeds, people tend to take shorter, more careful steps. At faster speeds, stride length usually increases and step frequency (cadence) rises to keep up. Biomechanics researchers study these patterns to understand how speed influences gait mechanics and stability, since walking is one of the most… Read more

We hear about COVID-19 variants all the time, but what is a virus variant, how do they come about, and why do they matter? Students will explore these question and more in this lesson plan. They will use SimPandemic, a free online tool, to model what COVID-19 outbreaks look like when communities are exposed to different COVID-19 variants and understand how genetic mutations in a virus can lead to functional changes.

NGSS Performance Expectations:
  • MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
  • MS-LS3-1. Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
  • HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.

What is R naught (R₀), what factors influence it, and how does it shape the infection curves of an epidemic? Students will explore these questions and more in this lesson plan. They will then use SimPandemic, a free online tool, to model what a COVID-19 outbreak looks like in communities with different R₀ values. Remote learning adaptation: This lesson plan can be conducted remotely. Students can work independently on the Explore section of the lesson plan using the Student… Read more
NGSS Performance Expectations:
  • MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
  • HS-LS2-8. Evaluate evidence for the role of group behavior on individual and species' chances to survive and reproduce.

Can genetic or environmental factors affect our chances of getting a certain disease? In this activity, your students will model how an existing predisposition can impact the probability of developing an autoimmune disease using dice and M&M's® candy! Read more
NGSS Performance Expectations:
  • HS-LS3-3. Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
Modeling Biologic Manufacturing
Add Favorite
Lesson Plan Grade: 6th-9th
In this lesson plan, students will model the complex biologic manufacturing process. First, they will model the cellular expansion process that occurs in a bioreactor. Then, students will lyse the cells to isolate the proteins from the dyed cell debris. Lastly, they will model the advanced filtration process to purify proteins so they can be used as medicines.

NGSS Performance Expectations:
  • MS-LS1-2. Develop and use a model to describe the function of a cell as a whole and ways the parts of cells contribute to the function.
Preventing Outbreaks with Herd Immunity
Add Favorite
Lesson Plan Grade: 6th-12th
What is herd immunity, how is it achieved, and what impact does it have on outbreaks? Students will explore these questions and more in this lesson plan. They will then use SimPandemic, a free online tool, to model different levels of viral immunity in communities to understand how a population can reach the herd immunity threshold and the impacts that has on individuals and populations during a COVID-19 outbreak. Remote learning adaptation: This lesson plan can be conducted remotely. … Read more

What exactly is a vaccine? Can vaccines prevent outbreaks? How effective does a vaccine need to be to help a population during an outbreak? Students will explore these questions and more in this lesson plan by first learning the biology behind vaccines. They will then use SimPandemic, a free online tool, to model different vaccine parameters to understand how vaccines affect both individuals and populations during a COVID-19 outbreak. Remote learning adaptation: This lesson plan can be… Read more
