High schoolers explore how PCR works through various activities. In this biology lesson, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.

Young scholars explore recipes online for different types of candy, and simulate process of making candy to explain how candy makers rely on varied temperatures and basic chemistry to produce perfect sweets.

Fifth graders create their own solar panel. They use this experiment to see how the sun can be used as a form of energy.

Students experience problem-based learning as they use prior knowledge of the states of matter to keep a frozen juice bar from melting.

Students investigate coal samples and analyze its drying loss under controlled conditions. They establish the loss in mass of a sample when heated under controlled conditions of temperature.

Third graders examine the effect of sunlight on the earth. Individually, they pick an article of clothing out of a bag and sort themselves based on the color of the shirt and whether it should be worn on a cold or a hot day. To end the...

Students research how surface sea temperature changes throughout the year. They draw a time series of sea surface temperatures for each month of the year and a depth profile for a summer and winter month using an OceanExplorer Profiler...

Learners participate in a demonstration showing how rain drops grow by coalescence. They use ping pong balls and put them in an air stream. They end the lesson discussing flash flood safety.

Students make glue out of milk and vinegar. In this chemistry lesson plan, students combine curds of milk with an ammonia solution until a creamy liquid forms.

Students prepare Shoenbein Paper to test the ground level of ozone. They dip a strip of their test paper in distilled water and hang it at a data collection site. They determine the relative humidity of the data collection site. Using a...

High schoolers explore sources of high-energy radiation and calculate student exposure to ionizing radiation over the past year.

Third graders watch a demonstration and write in their journals their predictions about how time might affect the moisture in the two paper towels. Using a Berlese funnel, they record their observations when it comes the amount of...

In this science worksheet, students examine the hydrological cycle through the coloring of the picture that graphically organizes the concept.

Students organize rock samples according to their properties. In this earth science lesson, students predict whether they are igneous, metamorphic or sedimentary. They compare their prediction with the actual type.

Seventh graders explore how to make careful observations and gain valuable practice in drawing what they observe. They stimulate questions about the changes occurring in the apple. Students have an opportunity to ask questions that can...

Students investigate basic engineering principles, road construction and material science through a unique and fun hands-on activity.

First graders observe water changing states from a solid to a liquid to a gas. They predict what they think happen to ice cubes as they sit out. They paint water with paintbrushes outside the classroom in the sun and watch the water...

Young scholars discuss movement of air currents and then experiment to create visible models of air currents. Students connect the model to weather patterns.

Learners recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Young scholars explain the processes involved in the rock cycle. In this earth science lesson, students identify the different kinds of rocks. They complete a worksheet during the activity.

Students explore the characteristics of clouds, their formation, symbols used in their identification, and the relationship of clouds to weather. The instructional activity focuses on how they are formed and their classification.

Students see simulated lava flow down a simulated volcano. They examine how lava cools fastest on the surface.

In this chemistry overview worksheet, students review stoichiometry, states of matter, thermochemistry, gas laws, chemical bonding, molarity, chemical equilibria, and kinetics. This worksheet has 41 problems to solve.
