In this math activity, learners play a game using their number sense to make the highest or lowest number possible. Use this activity to explore place value and/or decimals.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

In this activity, the learner asks yes-no questions to identify a secret object (similar to Twenty Questions). This game is easy to adapt for different ages and different kinds of contexts.

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this math game (Page 17 of the Are You Game? PDF), learners investigate probability by tossing coins.

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

In this math lesson, learners identify and compare unit costs of given items. Learners use computation skills, problem solving and number sense to find the cost of an ounce of cereal.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

In this math lesson, learners are introduced to proportional reasoning through modeling, sharing, and questioning techniques.

In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

In this math activity, learners predict how many pom-poms they can toss inside a circle from three feet away. Use this activity to help learners explore probability.

In this card game, learners make two sets of three cards that are alike. Learners must justify to the rest of the players why the three cards belong in each set.

In this online activity, learners crack the special code imprinted on envelopes to help the U.S. Postal Service deliver the mail.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.
