Backyard Graphing
Source Institutions
In this math activity, learners will create a scale diagram of their backyard or other outdoor area on graph paper.
What Causes Rainbows?
Source Institutions
In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

The Size and Distance of the Planets
Source Institutions
In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

Measuring Wind Speed
Source Institutions
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.

The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.

Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.

Supersize That Dinosaur
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

Walking Polygons
Source Institutions
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°.

Playground Patterns of Cracks
Source Institutions
In this math activity, learners observe and sketch cracking patterns in pavement.

Stride Ruler
Source Institutions
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.

Angle Hunting
Source Institutions
In this activity, learners use a hand-made protractor to measure angles they find in playground equipment.

Weather and Climate: What's the Difference?
Source Institutions
This lesson plan enables learners to explore the differences between weather and climate.
Pace-Off!
Source Institutions
In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .

Jump Like a Frog
Source Institutions
In this math activity, learners jump and measure how far they can jump on different surfaces using different jumping techniques.

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.

It's the "Rain," Man
Source Institutions
In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

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

Stepping Out: Hop, Skip, Jump
Source Institutions
In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

Pedal Power
Source Institutions
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.

Telescopes as Time Machines
Source Institutions
This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.
