From a runoff to our body !

1. We talked about the Science Fair. Our proposal for a research question for the Science Fair is due Friday , January 31 , 2014. Mr.Pro explained that we will have 400 min. to work on the Science Fair during class , we shouldn't have to work that much at school.

  1. Science Fair:

2. We reviewed what we learned last class. Some students learned that viscous is the word used to describe that water sticks. Some learned that 70% of water is used for agriculture. Some learned that salt water can conduct electricity and that it is denser than water. Some learned that rivers , streams , runoffs and oceans have freshwater. Some learned that the water doesn't run out because of the Water Cycle. The process is evaporation , condensation and precipitation.

  1. What are properties of water?
  2. What do we use water for?

3.  Mr.Pro showed a demo to the class where a candle was dropped into ethanol and it floated and then it was put in water and it sank. The candle floated on ethanol because ethanol is denser than water. We discussed the observations , the smell of the ethanol and that not all clear liquids are water !

4. Then Mr.Pro gave a situation to the class where you where at a dessert and had salt water and you needed to purify it. But you only had certain materials. How would you do it ?

5. We discussed more about the Water Cycle. Water molecules can flow move through runoff , river ocean and stream. Water molecules can move from the cloud to the city. Water can move through a runoff and even through human's body !

We reviewed our water cycle diagrams with a partner. This where the instructions:

Will and Jorge discussing where a water molecule travels on their diagram.

5. Students needed to find the information on the books. Work on summarizing skills and collaborating skills. Students need to become experts on certain topics: Humidity , Formation of Precipitation , Kinds of Precipitation , Global Differences in Precipitation.

1.Explain Humidity               2. Explain How Precipitation forms
What is it ?                            Why are there different forms of precipitation ?
How do we measure it? How can we imagine precipitation forming?

3. Explain the Kinds of Precipitation 4. Explain global differences in participation.
What are they ? Look at the map and summarize differences
How are they different ? in precipitation based on locations in
                                                                    the world.        

1) Read the passage
2) Summarize the reading individually.
3) Share your summaries and write a group summary.
4) Share the group summary with me.

Gui reads the passage and is summarizing.

6.Then after the students became experts on their topic they changed groups and explained their topic to their new group.

Mathaus explaining his topic: Kinds of Precipitation.

Humidity: Water vapor in the air.
Forms of Precipitation: The water that's in the clouds fall because ice particles join together.
Kinds of Precipitation: Hail is big dumps of ice and Drizzle is very small drops of water falling from the sky.
Global Differences in Precipitation: Tropics have more precipitation. Tropics gets most rain because of the sunlight which cause more evaporation. Polar regions have less precipitation. 

Finally in our taskbooks and using our water cycle diagram, we needed to guess where the following energy changes occur.

                                       Then we had to label them on our Water Cycle Diagram.

Skills: Use diagrams to find information
