In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

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 gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this Bob the Builder(TM)-themed activity, learners explore the 3Rs (Reduce, Reuse, Recycle) by rotating through several activity stations.

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

In this game, students will become familiar with fish shapes, learn that fish within a given taxonomic family have similar body shapes, and discuss how different body shapes enable fish to survive in

In this activity (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

In this outdoor activity/field trip, learners explore the concept of population density.

In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

Learners work in teams to investigate how scientists use physical characteristics to classify living things.

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 activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.
