Students investigate electricity. In this Physics lesson plan, students experiment with insulators and conductors of electricity. Students use batteries as the energy source for the experiment.

Students observe fluid motion. For this Physics lesson, students explore the principles of Pascal, Archimedes, and Bernoulli. Students list their experiences with fluid movement.

Fourth graders explore the history of electricity. In this electricity lesson, 4th graders review the connection between electricity and magnetism. They do a research project on the history of electricity. 

Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

Fourth graders make toffee to observe both physical and chemical changes. They determine what types of changes that are caused by the cooking process and which are chemical, and which are physical. In order to do this they follow a...

Fourth graders determine what is meant by a physical change, and they demonstrate how they can make physical changes. They complete activities at stations that entail changes in color, size, texture, hardness, or state of matter. Using...

Fourth graders explore physical changes. They discuss that physical change is a change in size, shape, or state of matter of a substance. Students explore what change takes place when two substances can dissolve each other. They observe...

Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...

Students explore using energy from the sun for heating and cooking as they build and compare the performance of four solar cooker designs. This excellent two-day lesson has groups of students build and test a variety of solar cookers....

Young geologists utilize Moh's hardness scale to help them correctly sort and classify different types of rocks. This activity has everything you need, including an excellent example of the Mohs' Hardness Test, to successfully implement...

Students study practical data analysis within the constraints of the scientific method.  In this data lesson students collect and enter data into a computer spreadsheet then create graphs.

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 describe visual, textural, and other physical qualities of sample rock specimens. Using compare and contrast skills, students sort and classify the specimens according to their assessments of the qualities present in each....

Students discover the human and physical characteristics of desert regions. In this regions lesson, students describe deserts around the world, discuss animals, vegetation, water conservation, and how humans can care for the land.

Students design sleds. In this engineering lesson, students collaborate to engineer and build a real working sleds from the materials provided.  This lesson was originally designed to be taught to a group of female students.

Fourth graders classify animals. In this animal kingdom lesson, 4th graders research animal habitats and behaviors. Students connect to a zoologist via SKYPE and learn about animal classification. Students blog about preserving animal...

Students explore electricity by completing Internet activities.  In this physical science lesson, students identify an electric circuit and describe the characteristics of conductors, giving examples as well.  Students...

Get children's blood pumping with this primary grade lesson on the human heart. After learning about the important role this muscle plays in the human body, students monitor their heart rates and discover the importance of...

Young scholars study water and its energy. In this water energy lesson, students discuss hydroelectricity and make models of water turbines.

Explore physical science by reading Barthlomew and the Oobleck by Dr. Seuss. Discuss the moral of the story and the discretion an inventor must use when creating something they want instead of something they need. This instructional...

Young citizens construct an understanding of urban planning in this cross-curricular unit. Covering every aspect of city development from the political, economic, and social influences to sustainable building practices, this...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Here is a resource with a descriptive approach to explaining the scientific method. It's simple, but effective for both introduction and reinforcement of this concept.
