3.  Matter  Anything that has mass and takes up space.  Everything is made of matter. You, your desk, the pencil you are holding. EVERYTHING!  What_Is_Matter video clip What_Is_Matter video clip What_Is_Matter video clip

8. Pair Share: Partner A: What are the three states of matter? Partner B: Describe the motion of each state of matter. Partner A: Describe the space between each state of matter. Partner B: List the states of matter from most movement to least movement.

9. The Water Cycle  Water Cycle  The water cycle is the continuous process by which water moves from Earth’s Surface to the atmosphere and back.  Water cycle video clip

10. Accumulation

11. Based on this Picture.... What do you think evaporation is?

12.  Evaporation  Evaporation is the process by which molecules of liquid changes to a gas.  When the molecules heat up they rise into the atmosphere.  Ex: When you use a kettle and there’s steam coming out of it, that’s evaporation. Evaporation video clip

13. Transpiration Based on this Picture.... What do you think Transpiration is?

14. Transpiration  process by which plants lose water out of their leaves.  process by which plants lose water out of their leaves.  Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air. Transpiration The movement through plants

15. Based on this Picture.... What do you think condensation is?

16.  Condensation  Condensation is the process by which a gas changes into a liquid. The water droplets in the atmosphere collect around dust particles to form clouds.  Ex: Water droplets on the outside of a cold glass. Condensation video clip Condensation video clip

17. Pair Share Partner A: Describe Evaporation in your own words and give an example. Partner B: Describe Condensation in your own words and give an example. Partner A: Describe why on hot days the outside of a nice cold cup of lemonade has water on the outside of the cup. Partner B: Describe why on a cold day when you have a warm cup of hot chocolate why does it look like there is smoke coming from the top.

18. Based on this Picture.... What do you think precipitation is?

19. Precipitation  Precipitation are forms of water that falls from clouds and reach Earth’s surface.  Examples – Sleet, hail, snow and rain  Precipitation Clip Precipitation Clip Precipitation Clip  Precipitation video clip Precipitation video clip Precipitation video clip Rain Snow Hail Sleet Precipitation The rain falls

20. Accumulation Based on this Picture.... What do you think accumulation is?

21.  Accumulation  Accumulation is all the water on Earth—above ground and below ground  Ex: Oceans, Lakes, Ponds, Rivers, Streams, Water in organisms.

22.   Collection of water on the surface (not moving)   Ex. Puddles, lakes  Surface Water

23.   The movement of surface water. Water that moves in a channel, or on land.   Ex. When it rains and the water runs off the roof and down your driveway and into the storm drains.  Runoff Ballona Channel Runoff video clip

24.   Collection of water underground. Water seeps into the ground and flows below the surface in underground channels called Aquifers  Groundwater Aquifer Groundwater

25. Review of Water Cycle

26. Hi, my name is Ryan Raindrop. This is my story.

27. As the sun warms the water I evaporate from the ocean and become a gas.

28. As I rise into the cool air I group with other water molecules to form clouds through condensation.

29. The wind pushes the clouds toward the mountains

30. Cool air at the top of the mountain prevents me from going over. I fall to the ground in the form of precipitation

31. Once again I group with other water molecules. We accumulate in brooks or streams which lead to rivers and lakes or the ocean.

37. Now I wait for the process to begin again.

38. The sun is warming the surface of the water. As the water gets warmer it changes and begins to evaporate. Water is a liquid. The water vapour cools down and forms clouds. This is condensation. When a cloud gets full it begins to rain. This is called precipitation. The Water Cycle The warm water changes into a gas called water vapour and rises up.

40. Pair Share Partner A and B review and explain to each other the water cycle Accumulation Transpiration

41. Cycles Of Matter Cont…. What is the Carbon Dioxide – Oxygen cycle? Carbon – Oxygen Cycle Carbon Dioxide = CO 2 Oxygen = O 2 Producers take in CO 2 and out O 2. Consumers take in O 2 and out CO 2. Consumers could not live without producers and producers could not live without Consumers. Carbon cycle video The_Oxygen_Cyc le video 2 Getting Oxygen Plants_and_Anim als_video

42.  Nitrogen Cycle  Nitrogen fixation – the process of changing free nitrogen gas into a usable form of nitrogen.  Nodules – bumps on the roots of legumes (plants)  Bacteria that live in these legumes are the organisms that do nitrogen fixation. Nitrogen video clip Nitrogen series long video
