Where is the Sun?
Source Institutions
In this activity, learners verify that the Sun appears in a different location at a specific time every day of the year with one exception: on the Equinoxes.
Fizzy Nano Challenge
Source Institutions
This lesson focuses on how materials behave differently as their surface area increases.
Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.
Where Are the Distant Worlds? Star Maps
Source Institutions
This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).
The Shape of Floatation
Source Institutions
In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.
CD Spinner
Source Institutions
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Start a Rock Collection
Source Institutions
Learners follow a three-step process to start their own rock collection.
Measure the Speed of a Water Leak
Source Institutions
In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.
Launch It
Add to list DetailsIn this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.
Good News: We're on the Rise!
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.
Super Spinner
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.
Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
Composite Materials
Source Institutions
This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.
Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.
Cylindrical Mirror
Source Institutions
In this activity, learners create a cylindrical mirror to see themselves as others see them.
Iridescent Art
Source Institutions
This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.
Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei
Bouncing Balloons
Source Institutions
In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.
Get the Porridge Just Right
Source Institutions
Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.
