Envirolopes
Source Institutions
In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

Observing Insects at Night
Source Institutions
In this activity, learners set up a night time insect observation station with a light and sheet.

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.

Pi Graph
Source Institutions
In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

Stiff Bones, Bendy Bones
Source Institutions
Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

Exploring the Universe: Space Guess Quest
Source Institutions
Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.

The Poor Cartographer: Graph Coloring
Source Institutions
In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

Guar Gum Slime
Source Institutions
In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

Action-Reaction Rocket!
Learners construct a rocket from a balloon propelled along a guide string.

Blow-and-Go Parachute
Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Bernoulli Obstacle Course
Source Institutions
In this activity, learners create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.

Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

Building Bridges
Source Institutions
In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

Marshmallow Catapult
Source Institutions
In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

Solidly Platonic
Source Institutions
In this activity, learners follow simple directions to explore and create platonic solids.

Geothermal Power Plant Model
Source Institutions
In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.
