This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this math lesson, learners compare products to determine the best product.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this math lesson, learners participate in several activities where they apply measurement skills.

This lesson focuses on how materials behave differently as their surface area increases.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
