Trail Impact Study
Source Institutions
In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

Exploring Ultraviolet (UV) light from the Sun
Source Institutions
In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

Give or Take?
Source Institutions
In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

Big Sun, Small Moon
Source Institutions
Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

Cool It
Source Institutions
In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

Ice Roads: Steiner Trees
Source Institutions
In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

Build An Aqueduct
Source Institutions
In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

Telescope Treasure Hunt
Source Institutions
This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.

Spot the Sunspots
Source Institutions
In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.

Sawing Away
Source Institutions
In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

Logs to Soil
Source Institutions
In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.

Monitoring Amphibians
Source Institutions
In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

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.
