Blast Off!
Source Institutions
Students design and create their own air-powered rockets, in this hands-on activity.
From Polliwog to Frog
Source Institutions
In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.
Sled Kite
Source Institutions
In this activity, learners build a sled kite that models a type of airfoil called a parawing.
Make a Dinosaur Model
Source Institutions
In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.
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.
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.
Familiar Fossils
In this activity, learners explore different types of fossils by making their out of dough and objects from around the house.
What Gives?
Source Institutions
In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.
Heat Speeds Up Reactions
Source Institutions
In this activity, learners investigate the effect of heat on a reaction.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Hot Air Balloon
Source Institutions
In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
Earth's Water: A Drop in Your Cup
Source Institutions
This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour
As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
Wash Away Germs
Source Institutions
Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.
Straws and Pins
Source Institutions
In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.
Edible Earth
Source Institutions
In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.
Clay Bridges
Source Institutions
In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.
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.
