How Do Probes Get To Space?
Source Institutions
Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.
Thrill Ride
Source Institutions
In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.
Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
Sticky Structures
Source Institutions
In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.
Air Cannon
Source Institutions
In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.
Three Little Pigs
Source Institutions
In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.
Build A Battery
Source Institutions
The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w
Soapy Boat
Source Institutions
Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.
Going Buggy: Three Body Parts
Source Institutions
In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.
Let's Make Molecules
Source Institutions
In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).
It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
A Crayon Rock Cycle- Metamorphic
Source Institutions
This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.
Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.
Bring it into Focus
Source Institutions
In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.
Binary Challenge
Source Institutions
In this activity, learners cut out 5 paper cards and label them with 1, 2, 4, 8, or 16 dot(s) to explore binary digits.
Make a Dinosaur
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.
T. rex Cretaceous Treat
Source Institutions
In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.
A Crayon Rock Cycle - Igneous
Source Institutions
This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.
The Size and Distance of the Planets
Source Institutions
In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.
Bird Feeders
Source Institutions
In this activity, learners build a bird feeder or feeders to attract birds for observation.
