Today for our STEM Lesson we continued to work on our driving question: How can we determine the quality of a play dough process and how do the play dough materials change when they are mixed together? Yesterday we worked on the quality section today we worked on the mixing materials and the properties of the mixtures. We looked at our materials and their properties first. Then we came up with rules for our tests.

After that we started to conduct tests with different combinations of materials. Here is our results.

Then we drew some conclusions about different combinations of materials. Then welooked at the engineering design process and worked on finishing the plan stage. We watched Mrs. Ganus make a low quality batch of play dough. We then recorded her steps in a flow map. We then brainstormed how to change the order of the process to make a higher quality play dough. Here is our plan.
