Presentation Transcript

  1. Science Starter • *Pick up a Warm Up Sheet from the front • What do you do when you’re thirsty and you want some water? Is this the same for everyone around the world? • 2) Do you think that the majority of the Earth contains usable water? Explain why or why not.

  2. Agenda • Warm-Up • Guided Notes • Vocab Find & Posters • Water Cycle Rap • What goes up, must come down • Exit Ticket

  3. What are our BIG GOALS? • 80% mastery (how are we doing?) • Global awareness • Grit, Growth Mindset, Introspection, & Accountability

  4. Who’s your favorite deceased celebrity or historical figure? • What obstacles did this individual have to overcome?

  5. How much of this can plants, animals, and humans use? How much of this is frozen and inaccessible to humans? How much of this represents all the freshwater in the world? All the Water in the World All the water in the world All the FRESH water in the world (3%) All the FRESH water in the world that is not frozen in glaciers or icecaps All the FRESH water in the world that is available for humans and plants to use

  6. Less than 1% of Earth’s water supply is ready for human use

  7. CYCLES • What is a cycle? • A cycle is a repeating event or process • What are some cycles in our lives? • What cycles have we learned about this semester?

  8. What are the different places water can go as it moves through and around the Earth?

  9. What is the WATER CYCLE? • Water constantly moves among the oceans, the atmosphere, the solid Earth, and the biosphere. This unending circulation of Earth’s water supply is the water cycle.

  10. The Water Cycle • The continuous circulation of Earth’s water supply. • Water moves among the oceans, atmosphere, solid Earth and the biosphere • The energy source for the water cycle comes from the sun

  11. The Water Cycle • WC is balanced meaning that the average annual precipitation over Earth EQUALS the amount of water that evaporates. (What goes up must come down) • Evaporation exceeds precipitation over water and precipitation exceeds evaporation over land

  12. Vocab find!! • Use the textbook to find the definition of your assigned words. • Write your group’s assigned word in LARGE PRINT on construction paper. Posters will be displayed in class.

  13. Vocabulary Words • Evaporation • Condensation • Transpiration • Sublimation • Infiltration • Runoff • Precipitation

  14. 1 6 3 2 5 4 7

  15. How does surface effect the water cycle? What happens when you build a parking lot? 17

  16. WATER CYCLE BALANCE Q: What is the law of conservation of matter? A: The law of conservation of matter says that matter is never created or destroyed.

  17. WATER CYCLE BALANCE • How does the law of conservation of matter relate to the water cycle? • Water is never created or destroyed. It just cycles through different forms.

  18. WATER CYCLE BALANCE • Because water is never created or destroyed, the water cycle is balanced. • Balance in the water cycle means that the average annual precipitation over Earth equals the amount of water that evaporates

  19. WATER CYCLE BALANCE • There are local imbalances • Ex: over the ocean, more water evaporates than precipitates • Ex: over land, more water precipitates than evaporates

  20. ? 60

  21. FAST FACT The average person in the United States uses anywhere from 80-100 gallons of water per day. Flushing the toilet actually takes up the largest amount of this water.

  22. What goes up, must come down When it goes up – AGAINST GRAVITY

  23. What goes up, must come down When it goes down– WITH GRAVITY

  24. Circle the events where water moves WITH gravity: Infiltration Precipitation Runoff Evaporation Transpiration Square the events where water moves AGAINST gravity:Infiltration Evaporation Runoff Precipitation Transpiration

  25. Water Cycle Rap • https://www.youtube.com/watch?v=i3NeMVBcXXU • Quietly listen to rap and fill in your lyrics as we go

  26. Homework • Draw your version of the water cycle. • Label and define all steps in the process

  27. EXIT SLIP ___1. Which of the following processes in the water cycle goes againstgravity? a. Infiltration c. Run-off b. Evaporation d. Erosion ___2. Which of the following water cycle processes is most likely to occur on a steep slope? a. Infiltration c. Run-off b. Evaporation d. Erosion

  28. EXIT SLIP ___3.  Where is the 3% of Earth’s freshwater found? a. Oceans c. Glaciers b. Lakes d. Clouds  ___4. Where is 97% of Earth’s water located? a. Oceans c. Glaciers b. Lakes d. Clouds ___5. What process is represented by letter C on the diagram? a. Infiltration c. Run-off b. Transpiration d. Erosion
