Summer SAVY 2017, Session 1/Day 2- Dive into Design (Rising 1st)
Today was a fabulous second day for our Dive into Design class! We began our morning with a review of what a model is, and then we added more rigor to our concept of a model by reflecting on whether or not a model could be 2-D or 3-D. After a wonderful discussion and friendly debate, students all agreed that there are examples (including the blueprint swimming pool models they designed yesterday) of both 2-D and 3-D models. Students who brought models to share with the class got a chance to do so and describe why their object was a model.We then moved into an activity where students were presented with 2-D cutouts of shapes as well as 3-D solids and 3-D transparent relational geo-solids. Students were asked to think about how they would sort the objects. This was a rich activity where students explored the realm of volume, attributes, and dimension.
Next, students looked at a clear rectangular fish tank with water in it. They were provided with a variety of measuring tools such as tape measure, ruler, yardstick, and measuring cups. I had a discussion with students regarding how to evaluate which measuring tool you choose to serve your purpose. After we came up with examples, such as you would choose to use a hammer to screw in a bolt, students were given an opportunity to choose a measuring tool for a purpose of measuring something on the fish tank. Students discussed their choice of tool and what the purpose would be, such as length, width, depth, height, etc. Then the student measured with the tool they selected. I then had students look at the tank from an eye-level perspective and then a bird’s-eye view to get their reactions. They were amazed at how their perspectives change. I introduced the concept of volume. We also talked about accuracy in measurement and why it is important.
