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 activity, learners start their own field journal to better understand the wildlife in their area.

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, learners use their hands as tools for indirect measurement.

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

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 activity, learners model erosion using a clear shoebox and sand or soil.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

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.

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

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

Build time sense into the schedule by asking learners to predict what can happen in a certain amount of time: We have 20 minutes before outdoor time. What can you get done?

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

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

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

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.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.
