In this activity, learners use their sense of smell to explore the world on the nanoscale.

In this activity, learners explore why animals, specifically dinosaurs, live in families.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

Build and test a scale model of a rainforest canopy walkway.

In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

In this activity (page 2 of pdf), learners craft a model of a skate egg case and come to understand that cartilaginous fish such as sharks and shakes employ reproductive strategies that differ from th

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.
