In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

In this activity, learners work in teams to study the observation skills essential to scientific research.

In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

In this craft activity, learners create a string of cut-out moons and stars.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

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

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

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.

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.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
