Don't Be Nerve-ous
Source Institutions
In this activity, learners discover a brain process called habituation.
Chemistry Is Colorful
Source Institutions
In "Chemistry is Colorful" learners explore different materials through paper chromatography.
Getting Your Bearings
Source Institutions
In this activity, learners explore the concept of friction and how ball bearings reduce friction.
Exploring Earth: Land Cover
Source Institutions
This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.
Making Sense of Sensors
Source Institutions
In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.
Pendulum Snake
Source Institutions
In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums
Fish Wheels
Source Institutions
In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur
Chain Reaction II
Source Institutions
In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.
Test Density with a Supersaturated Solution
Source Institutions
Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.
Dive into Design
Source Institutions
Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.
Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.
Hanford at the Half-Life Radiation Calculator
Source Institutions
This quiz lets you estimate your annual radiation exposure.
Handheld Water Bottle Rocket & Launcher
Source Institutions
In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.
Lego Man Jump
Source Institutions
In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.
To Dye For
Source Institutions
Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.
Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
Stranded
Source Institutions
What's a more compelling problem to solve than being stranded on a deserted island?
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Aviary Architect
Source Institutions
In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.
Styrofoam Traps
Source Institutions
In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.
