Chemical Reactions in Your Mouth
Source Institutions
In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

Half Full or Half Empty
Source Institutions
In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

Nutritional Challenges
Source Institutions
In this nutrition activity (page 26 of PDF), learners consider the nutritional needs of people with specific dietary requirements, such as athletes, persons with diabetes and vegetarians, and create a

Vestibular-Ocular Reflex
Source Institutions
In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

What Do You Know About Microbes?
Source Institutions
This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

Oscillating Woodpecker
Source Institutions
In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

Energy Sources
Source Institutions
In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

Pollution Diffusion
Source Institutions
Learners design their own experiment to investigate how pollution diffuses through ground material.

Plankton Races
Source Institutions
In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

What's the Buzz?
Source Institutions
In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.
Plants: Hanging Tough
Source Institutions
In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

Mint Your Own Coin
Source Institutions
Coins are everyday objects which tell a lot about the people who use them.

How Our Environment Affects Color Vision
Source Institutions
In this lab (Activity #1 on page), learners explore how we see color.

Bone Stress
Source Institutions
In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

Personal Fan
Source Institutions
Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.
Leaves: Designing Leaf Arrangements on a Branch
Source Institutions
In this hands-on activity, learners investigate the functional design of leaves on a tree.

Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

Rock Bottoms
Source Institutions
Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

Phantom Phlame
Source Institutions
In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.
Diffraction Between Wax Blocks
Source Institutions
In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.
