A Scientific Cleanup
Source Institutions
This is a comprehensive lesson plan on page 85 for a group cleanup trip to a local beach, lake or stream. Learners keep track of the types and amounts of trash picked up and analyze this information.

Kites
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

Tabletop Biosphere
Source Institutions
In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.
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.

Double Dutch Distractions
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

Web It!
Source Institutions
In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

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.

Biodiversity of Feet
Source Institutions
This activity (on page 3 of the PDF under GPS: Biodiversity Activity) is a full inquiry investigation into biodiversity.

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.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
Effects of Solar Radiation on Land and Sea
Source Institutions
In this activity, learners explore the different heating properties of soil and water.

Feeding Facilitation: A Lesson in Evolution and Sociobiology
Source Institutions
This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

Twirling Rope Frequency
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

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.
