Flocking for Food
Source Institutions
In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

Do Your Own Dig
Source Institutions
In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

Extreme Sounds
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.
Growing Plants: Track Their Growth
Source Institutions
In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

Construction and Destruction
Source Institutions
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.
Big and Little Cups
Source Institutions
In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

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.

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.

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.

A Degrading Experience
Source Institutions
In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

Blazing the Trail
Source Institutions
In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

Statistics: Steppin' Out
Source Institutions
In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

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

Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

Tree Trunk Diameter to Branch Height Relationship
Source Institutions
In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

Using a Simple Astrolabe
Source Institutions
In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.

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

Collect Invertebrates to Determine Water Quality
Source Institutions
This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
