Wind Mapping with Bubbles
Source Institutions
Discover the wind's direction using bubbles, a map and a keen eye. Learners blow bubbles and note their general direction on a map, taking readings from different points around a building.

The Blindfolded Walk
Source Institutions
In this activity, learners work in teams to study the observation skills essential to scientific research.

Take a Hike!: A Family Forest Walk
Source Institutions
In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

Carbon Sequestration
Source Institutions
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

Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
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 .

Protect That BRAIN!: Mr. Egghead
Source Institutions
This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.
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.

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.

My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

How Big Were the Dinosaurs?
Source Institutions
In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

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.

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.

Rain Machine (Solar Still)
Source Institutions
In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
Signs of Change: Studying Tree Rings
Source Institutions
In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

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

Nature Journals
Source Institutions
In this activity, learners construct a home-made journal with simple, everyday materials.

Fishy Observations
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Rabbits), learners will visit a zoo, aquarium, or pet store to view a variety of fish.

The Shadow Knows II
Source Institutions
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.
