Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.

Put the math of measurement, numbers, and everyday life into improvisational skits.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.

In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

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

Learners imagine they are paleontologists in Florida, where they find (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

Learners identify an unknown liquid by comparing its behavior to known liquids. Learners drop liquids onto different surfaces and see how the liquids behave.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity, learners explore the web of connections among living and non-living things.

In this physics activity, learners experiment with the attractive and repulsive power of magnets.

In this food science activity, learners observe different plant-originated foods.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this activity, learners will observe birds in their backyard or local park. They will attempt to find common Ohio birds and will look for bird behaviors just like an ornithologist.
