Immortal Cell Line of Henrietta Lacks

This activity introduces cell division and cancer by incorporating the story and contributions of Henrietta Lacks.

It’s Giving Energy: Simulating Energy Flow In Ecosystems

This lab allows students to simulate energy flow in ecosystems, particularly the 10% rule.

Macromolecules: You ARE what you EAT!

In this video lesson, let's learn about Macromolecules. Carbs, Proteins, Lipids, and Nucleic Acids!!!

Photosynthesis & Respiration

Photosynthesis & Respiration tend to be difficult concepts in Biology. Check out our video lesson that uses creative visuals, diagrams, literacy strategies, and COMEDY to explain this!

The Carbon Cycle Game

In this game, students will simulate the carbon cycle by pretending they are a carbon atom traveling through the environment.

The Function of Organelles

This exploration can be done at home or in the school building. Students are required to research the functions of major organelles and then take photos of things around the building that can relate to each organelle. They must th...

The Ups & Downs of Pulses: Feeling Homeostasis

This completely FREE lab teaches students how to find and determine their carotid or radial pulses. The accompanying video defines homeostasis and factors that affect it.

Visualizing Calories: Energy in a Cheeto vs. a Marshmallow

This lab serves to introduce students to the function of macromolecules, more specifically carbohydrates and lipids. It examines the accuracy of nutrition labels, by physically burning calories in a Cheeto and a marshmallow.

Fizzing Livers: Analyzing Enzymatic Rates

This lab demonstrates the structure and function of enzymes.

Heads or Tails? Modeling The Principle Of Dominance

This lab uses two coins to model how genes are inherited according to Gregor Mendel's Principle of Dominance.
