This week, the students worked through the engineering design process as they designed and created their own paper chain. The students had two pieces of copy paper, one piece of construction paper, one piece of news paper, and one foot of masking tape to create the longest chain. The chain could be of any design, but the students only had twelve minutes to create. After the students finished, they measured the lengths of their chains, and added the length to a line plot.

This week, the students were introduced to the engineering design process. Class began with a story about an engineer named Rosie Revere. The students learned that inventions don't always work the first time, and it is important to learn from the mistakes. What a perfect way to introduce engineering! Next, the students watched a short video that models the engineering design process. Finally, we reviewed the steps of the design process, and discussed the engineering challenge for next week! This week, the classes are being introduced to the scientific method. To learn about this process, the students went through the steps as they completed a science experiment. The question that led the experiment was, "Can yeast cause a chemical reaction?" Time was a factor for our class, so the class did not research the question, but learned that yeast is a microscopic fungus. As the experiment was performed, the students practiced using the materials safely, and meeting their expectations for each other as they worked as teams. Finally, the class discussed the results, and compared them to their hypothesis. Student learned that the yeast and the hydrogen peroxide caused an exothermic reaction! Heat was release as energy, and they were amazed!
