In this math lesson, learners explore and investigate measurement using standard and non-standard units.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

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

In this activity, learners use their senses to collect information about a fruit and record their findings in a Science Journal.

In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

This activity (located on page 3 of the PDF under GPS: Temperate Rain Forest Activity) is a full inquiry investigation into tree growth rates.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

In this math lesson, learners make wallets or purses and then participate in a variety of money-related activities. First, learners make their own paper money and paper wallets or purses.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.
