Water Cycle Activity

Time to re-familiarize with the water cycle.
Visit the Pearson-Prentice Hall website for an active art activity on the water cycle.
Type in the webcode: cfp - 4024
Complete the activity, take the quiz, and then create a new blog post about the following:
  1. What is the water cycle?
  2. Does the water cycle have a beginning or end?
  3. Starting with a puddle on a sunny day, describe how water might move through the water cycle and eventually fall back as rain.
  4. Create a diagram (using Google docs or word) of the puddle to rain scenario you created for extra credit.

Investigating Ice Balloons

video

Last week we spent some time investigating ice balloons, balloons filled with water and then frozen for four days. Gasses within the water try to escape as the water freezes, creating incredible pathways of escape, emphasized when lit by a flashlight in a dark room. After a ten minutes or so we introduced food coloring to the ice balloon. Soon after salt, then sugar.

Students received an unlimited supply of index cards. Their sole task, other than to experience the beauty of the ice balloon, was to ask as many questions as they possibly could and write them down during the experience. One question per card. Each substance introduction evoked more questions.

Upon completion, they divided their cards into two categories - investigable questions vs research questions. Discussions on characteristics of each of these categories resulted.

Students could have the option of choosing a question and carrying out the experiment as a class activity or as homework.

Takes about 40 minutes for the investigation and 25 minutes for the question discussion.

Today you are going to investigate water.
  1. Go to the the USGS website and take the quiz to see what you know about water.
  2. Learn about water.
  3. Take notes on the structure of water and the properties of water in your composition notebook. Include diagrams and text in your notes. This will help you to create a useful poster related to water in class tomorrow.
  4. Go back the USGS website and retake the quiz to see what you have learned. Report your results to me.
Websites to use:
Create a poster detailing the structure and properties of water.
Take a screen shot of your poster and upload your poster as a jpg image to your blog in a new blog post.
