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.

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

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners investigate different types of bird beaks using household items which mimic different beak examples.

Learners work as a group to create a map of their community. They use pasta to represent people, and glue the pasta on their maps to show areas of large population.

In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.

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.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

In this activity (p.25 of PDF), learners investigate spores. Mushrooms produce millions of spores which are equivalent to the seeds of plants but without the massive food reserves.

In this Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.

In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this construction activity, students use a 2-liter bottle to build a fly trap.

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.
