Science Class Connect Rules

1. Science Class Connect Rules • Respect the classroom and our privileges • Do not pollute the chat box • Stay on topic • Science class connects are not free chat sessions • Respect the teacher and your peers • Be appropriate and use good language • Be kind to others • Class connects are a time to learn • Have fun! • Science is cool and full of lots of fun lessons and labs! If you are unable to follow these three rules your privileges will be taken away!

2. JEOPARDY!!!!

3. Which is represented by the arrow labeled 2 in the diagram? $100 Water is running and collecting along the surface. Water is absorbing heat energy and changing from a liquid to a gas. Water vapor is cooling and condensing into liquid droplets aloft. Water is being absorbed into the ground.

4. The class says: $100 The answer is: C. Water vapor is cooling and condensing into liquid droplets aloft.

5. In the diagram, which is demonstrated by arrow 3? $200 Liquid water evaporating from the surface to the atmosphere. Liquid water moving from the atmosphere to the surface. Water vapor condensing into liquid water in the atmosphere. Liquid water moving along the surface.

6. The class says: $200 The answer is: B. Liquid water moving from the atmosphere to the surface.

7. At which step of the water cycle does water change from one state to another within the atmosphere? $400 4 1 3 2

8. The class says: $400 The answer is: D. 2

9. Which type of water is the least dense? $300 Cold, salty water Warm, salty water Cold water with no salt Warm water with no salt

10. The class says: $300 The answer is: D. Warm water with no salt

11. Describe the water that is most likely to sink to the bottom of the ocean. $100 Warm, salty water Warm water with no salt Cold, salty water Cold water with no salt

12. The class says: $100 The answer is: C. Cold, salty water

13. Which explains how winds cause surface currents. $200 Winds cools the surface water. As the water sinks, it creates surface currents. Friction between the blowing air and the water drags the water along and creates surface currents. High-pressure air from the blowing winds presses down on the surface and creates currents. Winds evaporate water from the surface and increase the salt content. As the salty water sinks, it creates surface currents.

14. The class says: $200 The answer is: B. Friction between the blowing air and the water drags the water along and creates surface currents.

15. $100 Which arrangement of the sun, earth, and moon explains the highest high tide of the month?

16. The class says: $100 The answer is: Tides are at their highest/lowest when the moon and sun are aligned and pull in the same direction.

17. $100 Which arrangement of the sun, earth, and moon explains the highest low tide of the month?

18. The class says: $100 The answer is: Tides with a smaller than normal range of highs and lows; the gravity of the sun and moon work against each other

19. Which condition causes ocean salinity to increase? $200 High levels of precipitation Freezing of polar ice caps River water flowing out into the ocean Low levels of evaporation

20. The class says: $200 The answer is: B. Freezing of polar ice caps

21. Which condition causes ocean salinity to decrease? $200 River water flowing out into the ocean. Low levels of precipitation High levels of evaporation Freezing of polar ice caps

22. The class says: $200 The answer is: A. River water flowing out into the ocean
