Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

In this activity, learners will review the functions of basic digestive organs, understand how diet affects digestion, understand how digestive tracks may differ, and then step outside to compare the

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

During this lesson, learners will determine their blood pressure and learn about systolic and diastolic pressures.

Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.

In this genetics activity, learners discover how to extract DNA from green split peas.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this activity (pages 26-29 of the PDF), learners investigate how they can develop super memories by using mnemonic devices.

In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing

In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.
