Creating a Local Field Guide
Source Institutions
In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

Can Fishing
Source Institutions
In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

Clear Water, Murky Water
Source Institutions
How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

Egg Carton Nursery
Source Institutions
In this activity, young learners will make their own flower seed nursery in an egg carton.

Trail Construction
Source Institutions
In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

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.

Changing Shadows
Source Institutions
In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

Bug Hotel
Source Institutions
In this activity, learners will create a home for animal friends in their backyard using recycled materials. Some material suggestions include: pine straw and twigs.

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.

Styrofoam Traps
Source Institutions
In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

Earth Walk
Source Institutions
In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

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!

Coverslip Traps
Source Institutions
In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

Observing the Moon
Source Institutions
Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

Seas in Motion
Source Institutions
In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

Temperature vs. Height: Soda Geyser Series #6
Source Institutions
In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.

Plants Around a Building
Source Institutions
In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
