Students build and test structures that can best withstand earthquakes. They create their structures from playdough, cornstarch, grape-nuts and popsicle sticks and place their structures on a "shake table."

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.

Learners use litmus paper to begin to discover the qualities of acids and bases. They learn about pH by testing clear liquids for acidity with purple cabbage juice as an indicator. The video Streamkeeper, with Bill Nye, and other video...

When your upper elementary or middle school class is learning about chemical changes, these activities help demonstrate the concepts. In Part A, they submerge and place a nail partially underwater, then after a week they make...

Science does not need to be as hard as a rock. Pupils test 10 different minerals to determine their properties. The learners observe luster, streak, hardness, and fluorescence for each specimen. Afterwards, they compare and contrast the...

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Make science come in loud and clear. Pupils learn about how a speaker works by building one. The scholars first learn about electromagnetic fields by building an electromagnet. Using that knowledge, they build a crude speaker using a...

Engineer an autonomous underwater vehicle (AUV) to study concepts of physics. Using household materials, collaborative groups design and build an AUV and then test Newton's Laws of Motion as they apply them in underwater environments...

The four cycles in Earth's biogeochemical system are covered in this worksheet. Science stars fill in the blanks or define vocabulary terms pertaining to the hydrologic, carbon, nitrogen, and phosphorous cycles. This resource provides a...

Kids explore food choices, nutrition, and agriculture through a variety of sources and activities. They research unknown words on food labels, test the salt content in canned vs non-canned foods, and discuss processed foods. The lesson...

As a way to combine life and physical science, or simply as an investigation of plant transpiration, this lesson is sure to inspire! Middle schoolers capture the moisture given off by plants that are placed in different conditions. They...

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the...

El Nino, La Nina ... and the Santa Maria? The 11th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program explains the mechanism of El Nino/Southern Oscillation. Pupils use previous data to determine...

How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

Hopefully you have a sensor interface for your physics class to use with graphing calculators when collecting data with a light sensor. If so, read on. Use this resource for learners to predict and then test whether or not the intensity...

Plankton: so much more than just a SpongeBob character. Three different activities have kids looking at both phytoplankton and zooplankton in pictures, as well as collecting their own samples (depending on your access to a saltwater...

What better way to learn about muscle than by dissecting one? Using cow muscle (beef), learners compare bundles of yarn to muscle fibers as they explore each. The supplemental reading about astronauts losing muscle mass in space and what...

Here is a comprehensive and well-written lesson plan that results in learners building a standard wind turbine. Once built, teens can design a variety of experiments to test different factors. This activity is a noble undertaking that...

Students investigate the properties and uses of rocks and minerals. They build towers using only one material from a pile of stones, tiles, wood, etc. provided by the teacher. Students test the hardness of rocks by scratching them with...

Fifth graders perform tests to identify acids and bases.  In this chemistry instructional activity, 5th graders identify common household substances as acids or bases using cabbage juice indicator strips.

To prepare for the activity, STEM classes read about nanotechnology and the amazing properties of graphene. They collect a graphene sample from pencils, and then connect them into simple circuits to determine whether it makes a better...

Discuss an article about families affected by genetic disorders and their decisions about whether or not to evaluate their own genetic information. Investigate four different inherited disorders. Participate in a probability exercise....

Third graders, in groups, complete a science lab in which they perform a blind taste test on eight different foods--some sweet, sour, salty, and bitter. They determine which parts of the tongue "taste" which kinds of foods. they record...

Learners act as chief research scientists with the responsibility of testing a new drug. Students design a controlled experiment to test a hypothetical experimental drug. Learners write a clear, concise, and detailed plan to present to a...
