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.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

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.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

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 make a photographic image--without a camera!

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

You just ate a big meal and feel heartburn coming on. You take an antacid and feel better. Why? Heartburn is caused by stomach juice (an acid) burning the esophagus.

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

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

How can you make one shade of gray look like two? By putting it against two different color backgrounds! This activity allows learners to perform this sleight of hand very easily.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

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
