In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this "Sid the Science Kid" activity from Episode 107: My Shrinking Shoes, learners observe how plants change as they grow.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this activity, learners compare ways to measure their heart rates. Learners build their own stethoscopes and learn how exercise affects heart rate.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

In this activity, learners discover how their heart rate changes in different situations.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
