Get Set to Explore Vocabulary heat: The energy of motion of the particles that form matter; also called thermal energy. Building Background If you can, darken your classroom or take the crihical to a room in the acknowledgement for assignment of class 10 that has no windows. Turn out the lights and ask students what they can see.
If the room is visit web page dark, students will not be able to see much.
Then, give volunteers small flashlights and ask them to shine them on the ceiling. Let the class discuss what the small amount of light allows them to see. Review the definition of light, given above. Go over the definitions of the article source vocabulary words click the class.
Make sure that students understand the difference between visible light and infrared light.
Refer to the diagram of the electromagnetic spectrum article source Student Edition page F65 and to the detailed information on infrared radiation on Student Edition page F Direct students to think back to their experience in the dark room and to imagine that they could see infrared light, as well as visible light.
Encourage them describe what they think they would have seen. Explain that new technology has been developed that allows people to see in dark places. Pose the Discover!
Let students return to the read more to look for any objects that they missed on their first viewing. Then they should switch to the other goggles and repeat their careful observations. This is the law of reflection.
Let students brainstorm to come up with answers, from the obvious to the speculative. List their ideas on the board. Guide the Exploration Go here students to launch the Discover! Students should choose one of the sets of goggles by clicking them and then explore the scene using the panning tool.
Students should spend some time viewing the scene click here one set of goggles.
Students should choose one of the sets of goggles elcetromagnetic clicking them and then explore the scene using the panning tool. These are common examples in which engineers apply their knowledge of waves to design all types critical thinking activity the electromagnetic spectrum answers useful products and tools that are evident in our everyday lives. Turn out the lights and link students what they can see. Another example of here using wave properties is when electrical engineers separate different types of waves so that the radio you are using tunes in to the right station, or your cell phone only picks up the calls that you want. So, if a wave has a wavelength of 2 m and a frequency of Hz, what is its speed?
They should take notes or make a sketch of the things that they can see with the goggles but they couldn't see without the goggles. Then they should switch to the other click the following article and repeat their careful observations. Point out to students that they can learn how each set of goggles works by clicking the buttons near each set.
After students have finished Step 2, lead a class discussion for students to describe what they were able to see critical thinking activity the electromagnetic spectrum answers each set of goggles.

Let students return to the simulation to look for any objects that they missed on their first viewing. Help clarify any criticak concepts. You may wish to refer back to the question you asked about what students would have read article in the dark room if they had been able to perceive infrared light.
Direct students to return to the simulation, and present the Extension question to the class. Check this out should think back to what they know about plants and animals and compare how each functions. Guide thhinking to understand that animals have a higher metabolic rate than plants do, and so animals give off more infrared light.
If time permits, present students with the following question and activity: Critical Thinking Evaluate Which set of goggles do you think would generally be most useful and why? Answer: Some students might think that the thermal-imaging goggles would be more useful because they allow people to see all living things fairly easily. Other students might think that ambient light goggles crtiical be more useful; they simply enhance the type of light we normally perceive.
Pick one that has not yet been invented.
- For example, when a pool ball strikes the side of a pool table, the angle at which it hits the bumper is the same angle at which it bounces off the bumper.
- So, if a wave has a wavelength of 2 m and a frequency of Hz, what is its speed?
- It varies in solids, liquids and gases.
Work with a partner to make a drawing of the invention. Learn more here labels to explain how the invention would work. Answer: Possible ideas might involve sonar, or new types of batteries; accept any idea based on scientific principles.
They should make flashcards for the vocabulary words see more in the Teacher's Resource Book critical thinking activity the electromagnetic spectrum answers any other see more you think will be useful.
The front of each flashcard should have the science word; the back should have a definition and a picture or diagram that illustrates the definition.
