Neurotransmitters Contain Chemicals
Source Institutions
In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.
Goodness Gracious! Great Balls of Gluten!
Source Institutions
This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise.
Watch It Fly
Source Institutions
Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.
Better Hair Through Chemistry
Source Institutions
In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.
Charge Challenge
Source Institutions
In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.
Making a One-Second Timer
Source Institutions
This lab activity has learners create a pendulum with a one-second period.
Make Maracas
Source Institutions
Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!
Geometry: Let's Face It
Source Institutions
In this math lesson, learners identify, describe, and construct the five regular polyhedra.
Coral, Carbon Dioxide and Calcification
Source Institutions
In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.
Measuring Biodiversity
Source Institutions
Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.
Wetlands
Source Institutions
Learners create a model of a wetland to observe how it absorbs and filters water from the environment.
Inside DNA
Source Institutions
In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.
Molecules in Motion
Source Institutions
In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.
Scent Tracking
Source Institutions
In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.
Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.
Swinging Yo-Yo
Source Institutions
Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.
Harmless Holder
Source Institutions
Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.
For Your Eyes Only
Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.
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.
Vectoring: Steering a Plane
Source Institutions
In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.
