In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

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

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

In this activity, learners play a game to simulate the food chain.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.

In this plant science activity, learners role play as vegetables and weeds competing for nutrients.

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.

In this outdoor science/art activity, learners investigate spider webs by using string to create their own spider webs.

In this geography investigation, learners use a nighttime satellite image to observe areas of light across the United States and to identify patterns and spatial distributions of human settlements.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this activity, learners use maps to locate the Northwest Coastal region.

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 activity, learners will explore the roles of different animals in the food chain. They will create their own food chain using organisms of their choice.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.
