Science Starter 10/8 Identify the criteria & constraints for our new question. Write it in a T chart.

Science Starter 10/9 Answer the following questions: Who invented the radiometer? What to you thinks makes the flags move? Why does it only spin one direction?

Draw 7 of these, 1 per page

The words in the topic box of your graphic organizer write 1. Kinetic Energy 2. Light Energy 3. Electrical Energy 4. Chemical Energy We will only use 4 For now

In the bubbles surrounding the topic words you need to work with your group to...  Define the word  Rewrite the definition in you own words  Describe the process  Write an example  Draw an example  Write how this connects to our radiometer/flashlight demo

Science Starter 10/10 Define- Radiate Radiation When you are finished READ page 27 then take out your science notebook and update your project board as indicated on page 27

Observe the toaster What do you see? What do you hear? What did you smell? What do these observations indicate about energy?

Discuss the analysis questions on page 29 with your groups. Be ready to discuss as a whole class at the end of time.

Science Starter Happy Thursday : D Reflect- 1. Think about how you came from home to science class today. What are some of the different forms of energy you encountered? (This can be a list) 2. In social studies you are studying about going “green”, what does this have to do with energy? (complete sentences)

Your groups will investigate the following stations K 1, 2, 3, 4 Ag 2, 3, 4, 5 H 3, 4, 5, 6 Mg 4, 5, 6, 7 Xe 5, 6, 7, 8 C 6, 7, 8, 9 Bi 7, 8, 9, 10 Ra 8, 9, 10, 1 Ne 9, 10, 1, 2

When you are finished... Turn to page and with you group answer the “Analyze Your Data” questions on the next clean page in your notebook This apart of item 18

Investigation Expo On your poster include... Your group’s name, BKL #, and your individual names Your items investigated Then for each item list the forms of energy you identified The indicators for the energy

Time to Present Identify the changes you observed and the indicators that allowed you to detect each type of energy Ideas about the types of energy you saw in your objects Questions you may have about the energy types Which energy for is most commonly seen in your items?

Just incase you need a review...

What is Kinetic Energy? o Energy due to a object’s motion (kinetic) The bowling ball has energy because it is moving. When the ball strikes the pins the energy is transferred to the pins!

Examples of Kinetic Energy

What is Electrical Energy? o Energy caused by the movement of electrons o Easily transported through power lines and converted into other forms of energy

What is Thermal Energy? o Heat energy o The heat energy of an object determines how active its atoms are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will show less movement.

Sound energy Sounds are caused by vibrations. Sound travels in longitudinal waves. Sound transmits energy. The louder the sound, the more energy it transmits. The quiter the sound, the less energy.

What is Chemical Energy? o Energy that is available for release from chemical reactions. The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.

Examples of Chemical Energy

Light energy Light is a type of electromagnetic radiation. Light travels in straight lines. Light travels in transverse waves. Light transmits ENERGY. Our Sun (a star) is a light source, just like a filament lamp or a firefly. Which colour of light has the most energy, red or violet? violet

Nuclear energy summary Nuclear energy is the energy stored in the nuclear of atoms. When atomic nuclei join together it is known as nuclear fusion. When atomic nuclei are split apart it is known as nuclear fission. Nuclear fusion powers the Sun and other stars.

Elastic energy If you squash or c_______ an object or material, when you let go some materials have the p_______ to return to their original shape. We call the energy stored in a squashed or compressed material e_____ energy. The same is true for materials that are s_______ (put under t_____) they too have the potential to return to their original shape. They too store elastic energy. A Jack-in-the-box stores elastic energy ompress otential tretchedension lastic
