We began our Earth's Atmosphere expedition and have begun by answering the question "What is our atmosphere and what does it do for us?" Students worked in groups to learn about energy transfer: radiation, conduction, and convection. Then they were challenged to build a solar oven that would most effectively collect and retain the heat. Students brainstormed, drew a diagram, and then decided what materials they needed. Each student in the group was responsible for bringing the supplies needed. Thanks Rosalie for this wonderful idea!
On Monday, students will put the finishing touches on their ovens, and then test them for 20 minutes to see which group can increase the temperature of 100 mL of water the most. Good Luck!
They will finish the investigation by writing a paper reflecting on the characteristics of successful solar ovens.

Puzzle Time -- Grade 7
Seventh grade students have been investigating the interior of the Earth and learning about the different layers. Last week, they were challenged to put together two puzzles. One was cut from blank paper and the other was cut from newspapers. After the students put together the puzzles they worked in their groups to discuss the process and how it differed depending on the puzzle. Most groups concluded that the newspaper puzzle was easier because you can use the pictures and text as clues.
This week, we are learning about Alfred Wegener's Continental Drift Hypothesis and students have the task of blogging about how the two concepts (Puzzle Time activity and Continental Drift) are related. Be sure to check out the Grade 7 blogs to see what great connections they make.
Here are a few pics of students working on their puzzles!
