Regolith Formation
Source Institutions
In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

Stargazing
Source Institutions
In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

Fly a Leaf
Source Institutions
In this outdoor, windy day activity, learners "fly" and race leaves along a line to discover which types of leaves catch the most wind. Which leaves are the best fliers? Why?

Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

Beachcombing
Source Institutions
In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.
Disappearing Water
Source Institutions
In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

The Scoop on Habitat
Source Institutions
Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

DIY Weather Vane
Source Institutions
In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

Convection
Source Institutions
In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.
Making Rivers
Source Institutions
In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Homemade Rain Gauge
Source Institutions
In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

Start a Rock Collection
Source Institutions
Learners follow a three-step process to start their own rock collection.

Sandy Samples
Source Institutions
In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

Make Your Own Barometer
Source Institutions
In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

Egg Carton Nursery
Source Institutions
In this activity, young learners will make their own flower seed nursery in an egg carton.
River Catcher
Source Institutions
In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

Weather Forecasting
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
