Daily Objectives:

1. Can you design a working model that uses solar energy and heat transfer?

2. Describe the origins of pollution in the atmosphere, geosphere, and hydrosphere, (car exhaust, industrial emissions, acid rain, and natural sources), and how pollution impacts habitats, climatic change, threatens or endangers species.

3. Design Solutions to problems using technology.

4.  Describe the effect humans and other organisms have on the balance of the natural world.

5.  Recognize possible solutions to environmental problems, such as a lack of resources, energy shortages,  energy that produces pollution,…

P.EN.M.3 /  P.EN.M.4 /  E.ES.07.11 /  E.ES.M.1/  E.ES.07.41 / E.ES.07.42 / E.ES.07.41 /E.ES.07.42

Today in Class:

  1.  We discussed homework associated with the Sustainability Projects.
  2. Solar Cooker –   You and your group took your Solar Cooker model  and we ran some trials outside.  This was a great day to see if you could prove your solar cooker was working.  Did you get your marshmallow to melt?  Did you and your group  have a method that included recording measurable results?  What did you decide would numerically represent your data?  How did you / could you prove that your solar cooker was working faster (more efficient) than other groups’ cookers?

  3. You and your group should have completed page 3 on your Solar Cooker lab sheet.  You should have drawn a chart or table or graph.  You should have answered question #9 together— what modifications would you make to your experiment?
  4. This experiment really challenged your brains, I was surprised.  Many groups did not think about numerically representing the data– and you know it is important to show data that can be proven and compared to others’ data.  I have reminded you of this (last week when you were building and today).  So what do we do when our experiments do not generate the results that we are hoping for?  Make modifications based on our observations and make improvements!
  5. I told classes that we will go outside on another sunny day and run another set of trials— be prepared!  I will not announce the date ahead of time.  Hopefully your group was thinking about what you could do and answered # 9 together.


Homework:  Action work on your Sustainability Project!  What plans has your group made to actively engage with your project?  Are you running experimental trials?  Creating a scientific survey to generate data?  Designing a working model or Google.slides to show others, so they may learn about your project?  Which dates have you set up with your partners and community businesses/ adults / others?  All work is due May 25.
