In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

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

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

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

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

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 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 chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.
