In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this quick activity, learners observe how wind creates ocean currents.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

In this astronomy activity, learners create a model of the solar system using beads and string.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity (on pages 16-21), learners get a sense of geological time by understanding how big a million is.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.
