Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

You've probably heard of solar-powered cars, but what about wind-powered cars? Scholars build cars that can travel at least six feet. They can only use their breath to move the car—so, obviously, a sail might be a good feature for the...

Why do some magnets attract while others repel? Scholars use clearly labeled permanent magnets to explore the attractive question. They compare the behavior of like versus opposite poles to find the answer.

Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...

In this redox and electrochemistry worksheet, students identify the anode in electrode pairs of electrochemical cells. They also describe how a lemon battery works and how wet and dry voltaic cells work.

As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

Oceanography experts use candy to construct a model of a bio-physical mooring that would test a variety of factors. Each piece of equipment to be included on the mooring is described within the write-up. As pupils gather the candies for...

Students conduct experiments to discover the various ratios of oil to popcorn kernels. They determine which amount of oil produced the most popped kernels.

In this physics rules worksheet, students complete questions and answers in order to review physics rules with each other. Students complete 26 questions.

If only we could harness the energy of fifth graders, our energy problems would be over! The class discusses where different forms of energy come from and how we use them. They complete a chart of the activities that they do daily...

In this Ohm's Law learning exercise, students answer 8 questions which include multiple choice, graphs, and short answer. They write the definitions of voltage, potential difference, current, and resistance. They complete a graph about...

Students explore the different parts of the Cassini spacecraft. In this space science lesson, students create a model of the spacecraft using food products. They compare and contrast their model with the real one and evaluate its...

Learners examine the carbon cycle and how carbon atoms travel through it.  In this energy cycles lesson students describe how human activities affect the carbon cycle. 

The molecular properties of water are the focus of this chemistry-based assignment. Multiple-choice, true-or-false, matching, and fill-in-the-chart style questions query assignees about the forces that hold the water molecule together,...

Students examine the Dust Bowl and the effects of farming practices in the early 20th century. They read a handout, and conduct and discuss two experiments simulating soil erosion.

In this health worksheet, learners look for the connections needed to attain the knowledge of cardiac function. The sheet includes the background information.

Students explore how people use plants for food. They use pretzels to see how wheat can be turned into food.

Students comapre and contrast the lifestyles of the people of the Applachian region with their own community through in-class discussions, creative projects, hands-on activities, food preservation, homemade remedies, home construction,...

Class members read 25 clues about all areas of science, including biology, chemistry, weather, physical science, and insert their answers into a crossword puzzle. There is no word bank and the middle schoolers would need experience with...

To conduct an orchestra, a conductor’s conduct must be above reproach. What fun! Light a match under your readers by having them read a series of definitions and find the homograph that matches. If students don’t contest, you could...

STEM scholars investigate sound attenuation by conducting an experiment in which they compare the farthest distance that they can hear a sound with and without ear protection.

In this physics learning exercise, students complete 11 short answer questions related to general metrology. They define basic metrological terms.

In this ammeter worksheet, students answer eleven questions about ammeters, multimeters and types of circuits. They identify different types of circuits given schematic diagrams.

In this sunspot cycle and solar irradiation worksheet, students use 2 graphs of daily total solar irradiance and sunspot activity to solve 3 problems. They find the average solar irradiance during a given time, they determine the...
