Ice Melt
Source Institutions
In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.
Universal Indicator Rainbow Trout
Source Institutions
In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.
Homemade Butter
Source Institutions
In this activity, learners will turn cream and salt into butter—using marbles. Learners will explore how shaking up fat globules help them create homemade butter.
Nebula in a Jar
Source Institutions
In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.
Planaria Fishing
Source Institutions
In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.
No Pressure
Source Institutions
In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.
Crash Landing!
Source Institutions
In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
Five Second Dash
Source Institutions
This is an activity about prediction. How far can you hop in 5 seconds? Could you make it to the door? Across the room? Everyone lines up and tries it.
The Stroop Effect
Source Institutions
In this activity, learners experiment with the Stroop Effect by challenging themselves and others to try and read a list of colors as quickly and accurately as possible, with a twist.
Yummy Gummy Double Helix
Source Institutions
In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.
Brick Drop Challenge
Source Institutions
In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.
Bubble Cups
Source Institutions
In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.
Familiar Fossils
In this activity, learners explore different types of fossils by making their out of dough and objects from around the house.
Great Openings: Slots, 35 Sense, and Hole In One
Source Institutions
These three short activities challenge groups to fit objects through paper and index cards: "Slots" presents the challenge for one learner to figure out which objects fit through a hole cut by another
Make a Museum Collection at Home
Source Institutions
In this activity, learners will create their own museum collection using their favorite toys, drawings, or collection.
Density Stacker
Source Institutions
In this physics activity (page 8 of the PDF), learners will explore the property of density.
Dr. Vet: Noses, Ears, Legs and Eyes
Source Institutions
In this activity, learners practice counting and multiplication as they figure out how many animal body parts they have to examine as "Dr. Vet."
Are you a Square or a Rectangle?
Source Institutions
In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.
Water Filter
Source Institutions
In this engineering activity, challenge learners to invent a water filter that cleans dirty water.
