Water cycle presentation
- 1. WHERE IS WATER FOUND? THESE GRAPHS SHOW HOW MUCH OF EARTH’S WATER IS FOUND IN DIFFERENT FORMS. Activity in Class: First review some concepts, using a cup od fresh water, salt and ice to depict how’s the Earth’s water distributed, the activity will teach students how to get water, and also will allow them to get deeper understanding of the water cycle. In the following slide a review of concepts using a real image of any given section of land. Objective: Learn about the water cycle, and understand how water systems work in our Earth
- 2. PURPOSE OF THE ACTIVITY • In this activity, students will be able to understand the water cycle, they will also be able to review previously learned concepts like: waters distribution in our Earth, how much fresh water is available for us to drink, how important is to save fresh water. • Students will be able to get their own fresh water from condensation, concept that is part of the water cycle but somehow is “invisible” and sometimes difficult to grasp
- 3. REVIEW: THE WATER CYCLE Write in the blank spaces what is needed to go over the water cycle
- 4. AN ENDLESS CYCLE Write your own ideas here: ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ ____ This part of the PBL has to do with creative thinking, it doesn’t mater where they start or what they write, is about brainstorming.
- 5. UNDERGROUND WATER Groundwater Formation What are the saturated and unsaturated zones? Where does water collect? In this part students are just reviewing concepts before they get to start the activity.
- 6. TIME TO GET IDEAS AND FIND SOLUTIONS FOR THE ACTIVITY (THE CASTAWAY), USE THE DIAGRAM AS A GUIDE
- 7. THE PROBLEM: WE ARE HERE, AND NO FRESH WATER, WHAT WILL WE DO?
- 8. FIRST STEP: WE NEED TO ASSESS THE SITUATION AND GET SOME IDEAS What do we know about humans needs to survive? Why do I need to know about the water cycle? How we’ll find a solution to our problem?
- 9. IDEA THAT WILL BE USED IN THIS ACTIVITY
- 10. OTHER IDEAS ON HOW TO GET WATER? Rain Water? Underground water? Use leaves: Use tree branches on the floor: Use rocks: Use other:
- 11. DEBRIEFING TIME Great ideas Not so good ideas Good ideas
- 12. CONCLUSIONS WRITTEN BY STUDENTS Group I Group II Group III
