In this activity, learners will build a design and build a place for pollinators to drink from.

This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

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.

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

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.

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

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

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

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this activity, young learners (2 years and up) explore the world of insects and other "bugs" by Making a "bug hotel" with recycled objects.

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.

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 observe and record living things with in outlined outside space.
