In this math lesson, learners analyze the density of liquids in order to explore linear functions.

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 physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

Learners will understand the relationship between climate change and sea-level rise.

In this environmental health activity, learners investigate their own vital lung capacities.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.

In this math lesson, learners compare products to determine the best product.

In this math lesson, learners participate in several activities where they apply measurement skills.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

This lesson focuses on how materials behave differently as their surface area increases.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
