Pop Rockets
Source Institutions
In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.

Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Copter Engineering
Source Institutions
In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

Rainbow Refraction
Source Institutions
In this activity, learners will explore how light can refract or break apart into different colors.

Lub Dub: Make a Heart Valve
Source Institutions
Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

Kepler Paper Model
Source Institutions
In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

Straw Rockets
Source Institutions
In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

Helicopters
Source Institutions
In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
Building Houses: Build a Cardboard Tube House
Source Institutions
Build a house you can fit inside, using cardboard tubes.

Drip, Drop, Drip, Drop
Source Institutions
In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

The Wave
Source Institutions
In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal
We Have Capture!
Source Institutions
Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.

Make a Model of a Home Made From Shipping Containers
Source Institutions
In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

Build-A-Membrane
Source Institutions
In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

Target Practice
Source Institutions
In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
Ride on a Slide: Toys or Tubes Ride Slopes and Angles
Source Institutions
This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

Crazy Camouflage
Source Institutions
In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
