Night Eyes
Source Institutions
In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

Pollution Patrol
Source Institutions
In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Heart of the Matter
Source Institutions
In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

Control a Bird’s Flight
Source Institutions
In this engineering design challenge, learners make a bird and then control its flight with attached strings.

Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

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

How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

Backard Bioblitz Bonanza
Source Institutions
In this activity, learners will observe and record living things with in outlined outside space.

PVC Water Squirter
Source Institutions
In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

Homemade Rain Gauge
Source Institutions
In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

Powdery Mildew Fungi: Classification and Ecology
Source Institutions
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

Creating a Soil Map
Source Institutions
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.

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

Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Solar System in My Neighborhood
Source Institutions
In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

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

Stargazing
Source Institutions
In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

Pollen Tracks
Source Institutions
In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even
