Wave Machine
Source Institutions
This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.

Egg-cellent Landing
Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.
Growing Plants: Track Their Growth
Source Institutions
In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

Seismic Slinky!
Source Institutions
Did you know that a Slinky makes a handy model of earthquake waves?

Erosion and Floods
Source Institutions
In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

Water Sphere Lens
Source Institutions
In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

Evaporation
Source Institutions
This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

Seeing Your Retina
Source Institutions
In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

Eddy Currents
Source Institutions
In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

Cover Your Mouth
Source Institutions
In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

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

Secret Codon
Source Institutions
In this activity, "write" a secret message in genetic code as beads on a string.

Glue Stick Sunset
Source Institutions
In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

Wild Sourdough
Source Institutions
In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

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.

Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.

Aluminum-Air Battery: Foiled again!
Source Institutions
