In this activity, learners will take a walk with their family and incorporate a scavenger hunt. They will explore topics like ABC’s, numbers, colors, and shapes as they search for related items.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

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 activity, learners use a hand-made protractor to measure angles they find in playground equipment.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

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 math activity, learners jump and measure how far they can jump on different surfaces using different jumping techniques.

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

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this activity, learners model a population of deer and see how the number of deer changes over time.

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

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