In this activity, learners examine how brine shrimp populations can survive in some of the harshest environments.

In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.

Learners use several types of insect sampling and collection equipment to make an insect collection. Learners can collect insects from their schoolyard or yard at home.

Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

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 activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners will explore how the human brain interprets environmental stimuli.

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

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.
