In this environmental health activity, learners investigate their own vital lung capacities.

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

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.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

This activity (on pages 15-23) combines interactive role-playing and graphing to introduce learners to the health affects of pollen.

In this activity (on pages 16-21), learners get a sense of geological time by understanding how big a million is.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

Learners draw and describe a leaf, and then re-find leaves drawn and described by other learners. Learners can observe leaves outside, or leaves may be brought into the classroom.

In this investigation, learners gather information on various food items during a field trip to a local grocery store.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this lesson, learners will practice graphing and statistically analyzing data.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

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
