The great men of science is the theme of this collection of science lessons designed for 5th graders. Galileo, Linnaeus, Just, and Julian are the scientists who are studied. Learners examine each man individually and complete activities to explore the discoveries, inventions, and contributions of each of these amazing scientists. This fabulous series of lessons would be well worth doing with your 5th grade class.
You could call this five presentations rolled into one resource! The first topic of concern is the characteristics of electromagnetic waves.The electromagnetic spectrum is examined next, followed by the behavior of light. Several slides are dedicated to color, and even optical illusions are introduced. This may be one of the most comprehensive collections of slides on the topic of electromagnetic waves that you will come across! Use it when introducing high school physical science starters to this brilliant topic!
All aspects of the path of light are included in a great summary. Internal reflection and the angles of paths in different materials are explained and the behavior of visible light through lenses and the effect on focal points are detailed. Your class will enjoy the diagram giving parallels between the eyeball and a camera.
When young physicists study light, they will need to explore refraction, fiber optics, and birefringence. Within this resource are the background information and activity instructions for exploring all of these phenomena. Use all of the included material for a well-rounded unit on the behavior of light, or choose one of the many activities to support your own curriuclum.
For this Sombrero Galaxy worksheet, learners observe infrared images taken by the Spitzer Infrared Telescope and the Hubble Space Telescope. They answer 9 questions about the details of the images such as the radius of the stellar component, the thickness of the dust disk and the diameter of the bright nuclear core.
Eighth graders are introduced to concepts related to the Solar System. In groups, they participate in an experiment in which they must describe a ray of light and how it travels. They draw a diagram of the electromagnetic spectrum and describe the wavelengths associated with each type of light. They end the lesson plan by showing how light is reflected by mirrors.
Students investigate the integrity and strength of different types of food wraps. They test the wraps and create a graphic organizer for the data. Once it is organized then a lab report can be written. The lesson plan contains background information for the teacher who may not understand chemistry.
