Even though volcanoes look alike, they can be very different based on the types of lava that erupts from their surface. Learn about strata volcanoes, shield volcanoes, and the varying viscosity of lava with an engaging hands-on...

More asthma attacks happen at higher altitudes, but why? Scholars complete worksheets, learning about homeostasis and feedback related to breathing. Then, they work in small groups to experiment with breathing in limited amounts of...

Learners are introduced to a gas chromatography using a discovery-based approach. They are presented with a scenario/industrial application where their job is to verify that the company's mouthwash contains a specific percentage of...

Make sure your house is warm in the winter. Pupils analyze graphs of heating costs for two similar houses and make hypotheses for why the costs differ. They then build models of houses with appropriate insulation to reduce heating costs.

Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

Learners, in groups, receive a box of artifacts. They record their findings and discuss what the items would have been used for. They come together at the end of the lesson to share their findings.

How effective are cells at repairing UV damage? An inquiry-based lesson has learners experiment with organism by exposing them to various levels of UV light and then examining their DNA after a period of time. Pupils test different...

Students work for a company that produces acetylaslicylic acid, aspirin. They have been assigned the task of determining if different packaging materials and/or environmental storage procedures can increase the shelf-life of the product.

The scientific method is emphasized in this engaging and exciting chemistry lesson. Learners get to create Alka-Seltzer cannons out of film cannisters, water, and Alka-Seltzer tablets. Carbon dioxide gas builds up inside the cannister,...

Here is a full-fledged investigation of light waves, the electromagnetic spectrum, and element spectra. Physicists research a scientist that contributed to our understanding of the behavior of light. They take notes on your lecture, and...

Comprehend that many human characteristics-all physical traits and possibly many personality traits-are determined by our genetic makeup. These activities demonstate that all physical traits are genetically determined, some evidence...

Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.

Middle schoolers explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth...

Students examine how to design and implement experiments.  In this paper towel experiment lesson students test the strength of paper towels. 

Students record observations of ladybird beetles and aphids. They develop questions concerning the behavior of ladybird beetles and aphids that are testable by a classroom experimentation. Students develop an investigation.

Second graders experiment to find if pollinators have color preferences.  In this plant and bug lesson, 2nd graders gather information about how flowers pollinate. Students participate in a pollination experiment using the...

For this chemical reaction worksheet, students investigate the reaction that makes curds and whey. They mix milk and vinegar and run it through cheesecloth to collect the solid. Students make observations, read about curds and whey, and...

Students, in groups, design their own experiments to determine how the mode of application of the virus extract affects the various plants that students have grown from seed.

Students construct their own pendulum. In this physics lesson, students design an experiment to find the factors affecting its period. They formulate a conclusion based on experimental data.

Students are given a variety of materials and are asked to design a heat loss experiment that results in a reasonable explanation of "Why don't whales have legs?" students work with the theory of natural selection.

Students design and conduct investigations that illustrate the process of decomposition. After a lecture/demo, students simulate the process of soil composting in the classroom. They closely chart the decomposition of their soil.

Students work in groups to research biomass using the International Energy Agency's website. Students use evidence from the web search to assess biomass energy potential in Pennsylvania as part of a classroom "Alternative Energy...

Students design and conduct experiments in order to identify the components of lake water environments that are affected by winter ice cover. They use the experiment results to propose effective human management of these ecosystems.

Students study genetics and evolution. They evaluate a group of organisms and estimate their genetic relatedness. Then they use an online program to check the accuracy of their estimations and make a branching phylogenetic tree which...
