In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.

In this math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.

In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.

In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.

In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity, learners use their hands as tools for indirect measurement.

Build time sense into the schedule by asking learners to predict what can happen in a certain amount of time: We have 20 minutes before outdoor time. What can you get done?

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.

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