Source Institutions
In this water activity, learners discover ways to move water across the water table.
Exploring Shadows
Source Institutions
This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan
Exploring Structures
Source Institutions
This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different
Hidden Alarm
Source Institutions
In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.
Tempest in a Teacup
Source Institutions
In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.
Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
Whodunit?
Source Institutions
In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.
Electroscope
Source Institutions
In this activity, learners make an electroscope out of a foam cup, straw, aluminum pie pan, thread, and foil. Learners use their electroscopes to test for static electricity.
Confetti Launcher
Source Institutions
Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.
Convenient Carrier
Source Institutions
In this design challenge activity, learners invent a convenient way for someone using crutches or a wheelchair to carry small personal items.
Exploring Ramps
Source Institutions
This guide features three related ramp explorations in which learners investigate the following science concepts: when placed on a ramp, some objects roll, others slide, and others stay put; the shape
Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Drip Drop
Source Institutions
In this water activity, learners explore how water drops behave on different surfaces.
Periscope
Source Institutions
In this optics activity, learners build a spy tool to secretly view things over walls or around corners.
Kick Stick Challenge
Source Institutions
In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across
Extreme Kicking Machine
Source Institutions
In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.
Motorized Car
Source Institutions
In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.
Kicking Machine
Source Institutions
In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.
