Learners discuss the differences in the types of garbage. They use these differences to separate a sample of garbage. Partners then investigate the characteristics of landfills by searching on the Internet and by creating your own...

Students complete a unit with cross-curricular activities to learn about a healthy body and maintaining their health. In this health lesson, students complete 8 lessons to learn about good health, a healthy diet, healthy foods, healthy...

In this food energy worksheet, students review calories and how calories are determined. Students calculate how much thermal energy it would take to raise certain volumes of water a certain number of degrees. This worksheet has 3 word...

Students investigate Nanotechnology. In this physic's lesson, students evaluate a hands-on model made from chocolate syrup and pretzels to determine the advantages of size.  Students weigh chocolate syrup to determine it's wait...

In this ice on Mercury worksheet, students read about the data collected from the NASA Messenger and the Arecibo Radio Telescope indicating the possibility of ice on Mercury. Students solve 6 problems including finding the scale of the...

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

In this modeling the Keeling Curve activity, students use given data beginning in 1960 to create a mathematical model for the changes in atmospheric carbon dioxide over time. Students manipulate the equation to predict the carbon dioxide...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Learners explore how fish are able to move easily from one depth to another in water.  In this fish lesson students create their own balloon fish. 

For this redox reaction worksheet, high schoolers perform a redox titration to determine the number of iodide ions that react with each mole of iodate (V) ions in a solution. They calculate their answer using a given equation.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

In this comet learning exercise, students will read information about the Comet Halley that has been collected by recent space probes. Students will use this information to complete 7 short answer questions.

In this exercise, students practice estimating mass. Students receive immediate feedback and have the opportunity to get step-by-step hints and try questions repeatedly. CCSS.Math.Content.3.MD.A.2 Measure and estimate liquid volumes and...

In this exercise, students practice arithmetic word problems with mass. Students receive immediate feedback and have the opportunity to get hints, watch a tutorial video, and try questions repeatedly. CCSS.Math.Content.3.MD.A.2 Measure...

This interactive game has students apply skills in estimation, measurement, and basic addition using pearls. Students are asked to estimate the number of pearls in a treasure chest by making predictions and using number sense. The skills...

[Free Registration/Login may be required to access all resource tools.] In this learning module, students will learn the significance of using moles in converting between measurements and in understanding how much of something you have.

Solve word problems that involve converting between US customary measures of distance, volume, and mass. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this exercise, students practice arithmetic word problems with volume. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly. CCSS.Math.Content.3.MD.A.2 Measure and estimate liquid...

Unit reasoning helps us make sense of measurements by converting between measurement units and making reasonable estimates. For the Praxis test, we need to know common measurement units for length, time, volume, and mass, as well as how...

Convert between US customary measures of distance, volume, and mass. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Students will learn the concept of volume by determining the amount of sand that is needed to fill the long-jump pit at their school (or any rectangular- or square-shaped container). This lesson will explain the importance of knowing how...
