Young scholars decide whether or not there is or has even been water on Mars. They analyze temperature and pressure data from the Pathfinder mission to Mars, and then they analyze images of Mars, interpreting the landforms they see and...

Students break into four groups, starting at different stations. Each station should take about 10 minutes depending on prior knowledge of the topic. They then rotate when everyone is finished to the next station and discuss answers of...

Students make their own candy. In this science lesson plan, students observe how molecules interact with each other in physical changes and observe how the addition of heat can cause molecules to interact and form new molecules in...

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Students practice scientific inquiry while learning about bubbles. In this instructional activity about bubbles, students explore characteristics of bubbles. Students move through nine different "bubble" stations following directions and...

Young scholars investigate how friction affects the movement of a block across surface areas. They test five different kinds of surfaces—smooth surface, wax paper, a paper towel, course, and fine sandpaper. They predict and record the...

Students investigate the three states of water. In this physical science lesson, students watch the video "Earth's Ecology" and observe water in its' three states. Students record observations.

In this physical science worksheet, students complete 7 questions in the form of puzzles, word problems, and brain teasers about forces in fluids.

Second graders study how actions in the schoolyard and home can affect water quality. They discuss how rainwater can clean plants and sidewalks on its way to storm sewers. They draw an example of a simple maze that represents the maze...

Students investigate various chemical reactions when creating mixtures in ziplock baggies. For this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Students analyze and compare laundry bleaches by testing their oxidizing powers. They conduct their lab experiment, compare/contrast their results with other students' work, and complete a worksheet.

Pupils explore linear functions in this lesson when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the concept of slope...

In this water desalinization worksheet, students will design and construct their own desalinization plant. Then they will describe how they set up their experiment and if it worked or not.

In this polymer worksheet, learners make two types of cross linked polymers and they test their physical properties. These include their response to agitation, stretchability, viscosity, and resilience.

Fourth graders practice estimating temperatures. They practice in Celsius and Fahrenheit.

Second graders identify physical and chemical changes of matter. They distinguish between physical and chemical changes. They classify changes as physical or chemical.

Students investigate plastics and learn they are giant molecules made of carbon atoms. In this polymers and plastics instructional activity, students perform 3 activities which all include making polymers from household items such as...

Students explore and experiment with oil traps in rocks. In this rocks lesson plan, students explore the porousness of different rocks and how the more porous a rock is, the more oil it can trap. Students also participate in a lab step...

Students examine the different properties that affect water quality.  In this pollution instructional activity students play a game, complete a hands on activity and computer lab. 

Students build conductivity testers and investigate which solids and solutions conduct electricity. Working in groups, they predict which items will conduct electricity and record their answers on worksheets.

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

In this chemical reactions worksheet, students by comparing the chemical reactions of baking soda and baking powder. This worksheet has a graphic organizer and 7 short answer questions.

Students investigate why cells divide. In this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...

Students understand how clouds are formed. In this cloud lesson, students participate in three experiments to make clouds. Students complete activity sheets for each experiment.
