Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this activity, learners compare their own strength to ants through a series of physical tests.

In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.

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.

In this guided discussion activity, learners watch a video about Central Africa's Lower Congo River, one of the most biologically diverse rivers in the world.

In this activity, learners will experiment with salt and ice in order to turn a bag of ingredients into ice cream.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this card-based personal choice activity, learners review and sort COVID-19 and vaccine science information.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.

In this activity, learners observe fly behavior and then build a flytrap.

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

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

Learners make their own simple slide rules out of paper and learn how they work.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity, learners take apart a used zinc-carbon dry cell battery.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.
