Students investigate the rate determining step in a chemical reaction and how catalysts effect reactions. In this rate determining step and catalyst lesson, students work in groups to perform 5 tasks. They rotate each task and time how...

Students create experiments in class based on the erosion of Earth. In this erosion lesson plan, students perform a lab in class replicating the effects of erosion. Students finally draw their own conclusions based on the research...

Learners explore the concept of density and buoyancy. In this physics lesson, students discover the different factors that affect an object's density and buoyancy in water. Learners conduct several investigations to further...

Students calculate the densities of several liquids that appear similar.  In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in...

Students aim to explain the need for standardization of units of measurement. They pose their own standards for the value of a kilogram and compare them with the currently used standard.

Students find percents and unit price using popcorn.

Fourth graders determine the amount of energy required to melt ice using a calorimeter. They calculate the Molar Heat of Fusion of Ice.

Students explain the physical properties of matter. They, in groups, perform a variety of experiments, each demonstrating a different property of matter. A very nice, hands-on lesson plan!

Students explore the relationship between mass, volume and density. They use model boats to discover how changing mass and volume affect density. This is a very engaging lesson plan which provides great demonstrations and hands-on...

High schoolers compare and contrast photosynthesis and chemosynthesis as processes that provide energy to biological communities. They investigate the energy content of hydrocarbons used in coral communities.

Students use scientific method to determine cost-effectiveness of air freshener, and create PowerPoint presentations to share their results.

Young scholars perform an experiment with different types of bird eggs to determine what factors make them strong and able to stay on a cliff without rolling off.

Students watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

Middle schoolers make detailed qualitative and quantitative observations. They are introduced to the process of developing repeatable procedures. Students practice collecting data. They review measurement skills. Middle schoolers...

Students explore the various aspects of Einstein's energy equation and discover how energy is transferred from one form to another. In teams, they rotate through seven stations to experience such aspects of energy change through...

High schoolers investigate calorimetry and set up equipment to measure calories. In this calorimetry lesson plan, students make a calorimeter and compare large amounts of heated water with small amounts to show the difference in...

Students will explain the Archimedes's Principle. In this lesson on plankton, students will describe three factors that can affect the buoyancy of plankton. This lesson contains extensive background information, extensions, and multiple...

For this observing and identifying matter worksheet, students use a cookie in a bag and list 10 different descriptions of the cookie. They draw and label their cookie and given the cookie in the bag to their teacher who mixes all the...

In this conservation of mass worksheet, learners design an investigation to demonstrate the Law of Conservation of Mass. Students describe their investigation, collect data, graph the data and write a conclusion about what they discovered.

Students will design a scientific investigation. In this engineering design lesson, students will set up an investigation, collect data and form a conclusion about bridge design. They will use common household items to construct their...

In this conservation of mass instructional activity, middle schoolers experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products...

  Students build boats out of clay to test the buoyancy of the boat in water.  Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.   

Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Students practice 'delivering' eggs for the Easter Bunny along an obstacle course through which they perform various locomotor skills. They can also practice number and shape matching skills as they navigate the course.
