Sure to be a hit with your charges, here is a science lesson that has lots of hands-on activities packed into it. The focus is simple machines, and how they help us perform work. After a discussion and demonstration session, groups of...

Fifth graders examine and identify different simple machines that make up complex machines. They analyze and discuss different gadgets and appliances brought in from home, then in small groups examine one of the machines in detail. ...

The goal of this science lesson is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and easy to...

Fifth graders define work, force, and energy and calculate work done using a simple formula. They observe the teacher using an Equi-beam and identify the fulcrum, calculate different work problems, and participate in a class discussion.

Fifth graders identify the chemical and physical changes in the water cycle, carbon cycle, and the effects of weathering. They analyze the periodic table, and observe how vinegar reacts with limestone in a chemical reaction that causes...

Students compare the ability of a sample of carbon dioxide gas to absorb thermal energy compared to a sample of air. They build a visual representation of the greenhouse effect to illustrate the heat-absorption of atmospheric carbon...

Fifth graders explore changes in nature. They identify chemical and physical changes in the water cycle, carbon cycle, and weathering. Students explore a chemical or physical change based on a chemical formula. They examine the effects...

Fourth graders examine different types of clouds. In this cloud lesson plan, 4th graders examine pictures of different types of clouds and read details about them in the captions under the images. They make a cloud viewer by cutting out...

Students explore the different variables that affect surface temperature. They study how temperatures can vary widely within close proximity due to variables such as surface, directness of sunlight, and distance from buildings.

Students examine a set of data to try to determine the amount of cloud cover. In groups, they make a list of items that reflect light in the atmosphere and how different amounts of it can change the temperature. Using WorldWatcher,...
