Discover the power of wind energy. Learners design, build, and test wind blades in a hands-on experiment. They analyze the results to determine if they can make any improvements before gathering as a class to discuss their designs.

This is not your standard standardization lab! Take titration into the high-tech age with a simulated workbench. Learners perform titrations to standardize a sodium hydroxide solution using a KHP solution of unknown concentration....

What does the atmosphere on Mars look like? This fourth lesson in the series of five is designed for high schoolers. Scholars apply previous knowledge to add atmosphere to Mars in an online simulation. This comprehensive lesson includes...

In this chemistry olympiad lab worksheet, chemists are required to design two experiments. In one, they design an experiment to identify seven solutions given to them in pipettes. In the other, they design an experiment to determine the...

Lead your young scientists into an exciting world as they participate in a role play and experiment focused on proteins and DNA. After researching the Central Dogma of Biology, individuals or groups participate in a classroom...

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

Apply scientific principles to designing an experiment to study organisms living on the coral reef in our oceans. Through reading, individuals learn about the coral reef ecosystem and important factors that affect its function....

An outline walks your scientists through the steps of the scientific process. It begins by taking a general idea and developing a hypothesis based on related factors. Each investigator then plans a method for testing the hypothesis,...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Erosion is no match for our canals. Learners first perform experiments to test the amount of erosion for different materials and different slopes. Based on the results, they design ditches or canals that carry water from one location to...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Capillary action is the frugal chemist's dream ... the less liquid used, the more tests they can run! Learners experiment with the best design to maximize the benefits of capillary action. Using a liquid sample, they design a capillary...

You've heard of farm to table ... but what about farm in classroom? Junior agriculturalists embark upon a two-week journey into the science of growing things. Based upon the classic terrarium in a two-liter experiment, the activity goes...

Students experiment with seeds and germination. In this natural science lesson, students discuss the stages of germination. Students engage in a 4 part hands on science activity to view the process of germination.

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

Put your class's observational skills to the test with a science experiment about paper and plastic bags. After reading some background knowledge about the materials in plastic grocery bags, third graders interpret a chart to answer a...

Add a science experiment on medicine and drugs to your health lesson. After reading a paragraph on the difference between helpful and harmful drugs, kids choose which pictures of bottles they could find at a pharmacy. The last activity...

Explore transparancy with a science experiment on different materials. After reading an explanation on how to determine if something is see-through with a flashlight, kindergartners decide if certain materials are opaque or not....

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

Student demonstrate knowledge of recombinant DNA techniques (restriction enzyme digest, gel electrophoresis, and staining gel). They demonstrate skills needed to complete a gel electrophoresis and interpret a stained gel. Pupils solve...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...
