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 (page 87 of the PDF), learners move their bodies to better understand the three axes of rotation: pitch, roll and yaw.

In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.

This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.

In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners explore the etymology of dinosaur names.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!

In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.

In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.

In this activity (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.

In this activity, learners construct drawing machines using a cup, some markers, and a cricket to control the movement. A programmed LEGO RCX or Cricket is required for this high-tech version.
