In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg

In this Bob the Builder(TM)-themed activity, learners go on a nature walk outside and describe what they observe using their senses.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

In this activity, learners explore the possibilities of clay as a natural material.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

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

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

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.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.
