1. This is InTENTS!
How can we create two rectangles with the same area, different perimeter and test it using the scientific method?

2. Video: What is the scientific method?
Scientific Method Video:
Following the video have students create a sequence map of the scientific method based on what they saw. You may want to show the video multiple times if the students are having trouble creating the map.

3. How do I create a rectangles with the same area, different perimeters?
After you show the video, have the students create factor pairs for 16 and 24.

4. Create as many factor pairs as you can for the following products:
16: 1x16, 2x8, 4x4
24: 1x24, 2x12, 3x8, 4x6

5. Examples of Tent Covers
Point out in the first picture that the yellow parts are securing the top to the legs. They will need to make the fabric secure when creating the tent.

6. Anchor Chart Criteria: Content: Constraints:
Villages Elementary is having a field day. We need a tent to provide shade for the 8 grade level teachers.
The tent models will have an area of 30 square inches. Students must create 2 designs with different perimeters.
The tents must be designed first then tested.
Criteria:
Students will create a tent cover with the area of thirty square feet and create different perimeters while using the scientific process to generate and test their hypothesis of which tent will hold 8 people best.
Standards- Math- MD.4.8, MD.3.7 Science- SC.3.N.3.2, N.1.1
Design two rectangular covers with the same area, different perimeters.
Vocabulary: Math- multiplication, product, area, perimeter, sum, addition, factor pairs
Science- hypothesis, model, observation, scientific method, conclusion
Content:
It must be safe: stand on its own and the cover cannot fall down
All designs must be made on 1-inch graph paper. You will need one paper per student. They should fold it in half so they have space to create two designs. You may want to have extra on hand just in case.
Unit cubes: 16 per group
Construction paper (Poster board paper or card stock will all work. In our project we used construction paper)
Any type of cloth (Fabric stores should have left over scraps that are inexpensive if you don’t have any on hand).
Quality scissor so that it will cut through the cloth. (Students will be doing all the cutting)
6 Inches of tape for each redesign (12 inches total per group)
Must be able to fit 8 adults underneath comfortably. (Use counters, bears, or chess pieces to represent the adults for the model when it is tested)
Time (10 mins each) to imagine and plan; 20 minutes to make and test; 15 minutes to redesign and test
Record the construction and testing with the IPAD.
Constraints:
This is an example of what an anchor chart might look like that you could post during the design challenge. If the font size is too small, consider making individual charts to post on the board.

7. The Steps to the Scientific Method
Students should be able to fill this chart in and use their own words to fill in the boxes when appropriate.
