Glitter Bottles
Source Institutions
In this activity, learners will create glitter bottles with adult supervision. These are a fun way for little ones to practice observing and making comparisons.
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.
The Web of Life
Source Institutions
In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.
Nice and Nasty
Source Institutions
In this math game, learners throw dice and place the numbers in one of four boxes. Learners repeat this three more times and the learner with the largest four digit numbers is the winner.
Outrageous Ooze: Is It a Liquid or a Solid?
Source Institutions
This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.
Tri, Tri Again
Source Institutions
Learners estimate how many small triangles will fill a larger shape. Then they use a triangle stamp (or stencil made from a file folder) to fill the larger shape with triangles.
COSI Quicksand
Source Institutions
In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?
Give Me a Brake
Source Institutions
In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.
Multitasking Mania
Source Institutions
In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.
Pollution in Our Watershed
Source Institutions
By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from
Build Your Own Solar Oven
Source Institutions
Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
Klutz-Proof Density Column
Source Institutions
Making liquids of different densities to perfectly lay on top of each other can be a frustrating exercise. The Exploratorium created this activity as a fool proof way of making a density column.
Leaves: Designing Leaf Arrangements on a Branch
Source Institutions
In this hands-on activity, learners investigate the functional design of leaves on a tree.
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.
Marble Run!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.
Crystal Painting
Source Institutions
In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.
Angle Hunting
Source Institutions
In this activity, learners use a hand-made protractor to measure angles they find in playground equipment.
Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.
Wolf Survival
Source Institutions
In this activity, some learners pretend to be wolves, while the other learners pretend to be the prey of the wolf. The goal of the simulation is to have the wolves work together to survive.
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.
