Learners discover their magnificent breathing machine. In this science lesson plan, students learn the functions of the lungs in our bodies and become aware that in breathing an exchange of gases takes place in the lungs.

Students experiment with Newton's Third Law of Motion. In this physics and motion instructional activity, students complete two experiments to illustrate force and its equal and opposite reaction. Students first work in pairs to exert an...

Students explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...

Young scholars explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence...

Students work in small groups and use a hand-held vacuum pump with a balloon under the dome with some air. Another deflated balloon is attached to the end where the air goes out. As the air is drawn out of the dome the first balloon with...

Students engage in an experiment that tests how much air we breathe in and out during the respiration process. In this respiration lesson, students blow a typical breath's amount of air into a balloon. They use a ruler to measure the...

Second graders pop popcorn as a way to experience the scientific process. They form a hypothesis, carry out an experiment and explain their findings.

Third graders are introduced to the concept of gravity by observing different objects being dropped from a high point. In groups, they complete the same activities Galileo did and record their observations. To end the lesson plan, they...

Students investigate chemical energy. In this physical science lesson, students blow on saltine crackers to demonstrate how chemical energy in food can be converted to motion. Students compare the saltine cracker experiment to how...

Pupils role play scientists to prove a hypotheses. They determine whether or not walruses stay warmer in water or in air. Students also determine in which environment they lose more body heat.

Students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also discover several things that engineers are doing to...

Students research hot-ballooning using Internet resources including an around-the-world balloon flight. They determine fact from opinion, examine point of view, and determine main idea, and details. They write a journal entry taking the...

Students investigate the concept of caves by conducting an experiment. The lesson contains background information for the teacher. They collect data while making observations and write a review of the concept once the experiment is...

Young scholars view video segments which reveal the parts of sound and what factors control sound. The viewing and post-viewing activities serve to reinforce the video segments using worksheets and hands-out experiments.

Learners observe organisms found in pond water with a microscope. In groups, they discuss how single-celled organisms satisfy their needs for food, water and air. They compare and contrast the needs of macroscopic and microscopic...

Students poll what sounds are caused by vibrations in things. They collect a variety of household items to test out their theories. A variety of experiments commence. Discussion of high and low tones occur.

As an experiment is demonstrated for them, students write down their observations and brainstorm questions that can help them understand what they saw. After watching the experiment again—which demonstrates a soda can collapsing due to...

Students watch the teacher make a cloud. In this water cycle lesson, students discuss the water cycle and see the formation of a cloud. The teacher leads the discussion including the role of water vapor, smoke and air pressure.

High schoolers research and analyze the causes and sources of Canada's extreme weather conditions. They conduct an experiment, complete a worksheet and predict the most likely locations for extreme weather conditions.

Fifth graders use the scientific method to conduct experiments on the temperature effects on organisms. In this temperature effects on organisms lesson plan, 5th graders observe and record the hatching or the developing of organisms into...

Students participate in a lesson designed to illustrate these concepts using simple materials. They use Science process skills to observe, measure, predict, make inferences, and communicate while completing the activity. Proper safety...

Students observe the growth of a seed, predict what will happen when seeds are planted without soil, and conduct an experiment using a hydroponics system.

Students analyze and experience the scientific method. They discuss the various steps of the method, conduct various experiments, and write a three-paragraph essay regarding their conclusion.

Learners explore the distribution of plant seeds. In this science lesson, students discuss plants that explode in order to spread their seeds. Learners create pea shooters and use dried peas to see how far they will travel.
