+ Design Challenge Students will design small boats made out of their choice of materials from the ones provided. The goal is for their boat to hold as much weight (washers) as possible in comparison to their classmates, but at least 50 grams. They will test their final product on Project Presentation Day. Specifications - Boat must float on water, not ocean water or any other kind on liquid - The boat needs to hold up at least 50 grams of weight Constraints - Can only use 4 kinds of well chosen and justified materials - Can’t be bigger than 12” by 12” - Only 2 days to complete Lessons Learned and Reflection

+ Develop Knowledge Students will develop understanding of buoyancy with an interactive lab activity on PhET Students will develop an understanding of pressure and its application to buoyancy through an inquiry lab that is an extension of the interactive lab activity Students will be refreshed on the idea of Forces, including Newton’s laws through a quick brainstorming activity. Finally, students will explore material properties through a web-search activity they will work on in pairs. Lessons Learned and Reflection

+ Ideate Solutions Students will first decide on what 4 materials they want to work with, and justify their answers in their lab journal. They will then begin brainstorming possible designs for their boat individually. As they brainstorm and make drawings, they need to justify and label all of their decisions. They will need to come up with at least 4 designs. Finally, they will get together in groups of 3 or 4 and pick one design that they all agree on, and justify their choice using content learned in the develop knowledge section.

+ Build Prototype Students will first get a green light from me to move onto the building phase of this lab once they have a chosen prototype. They will then use the materials they have chosen and create their prototype. Lessons Learned and Reflection

+ Test and Evaluate Prototype Students will first be given a chance to test their prototype against the 50g weight. They will then give a short presentation to the class that accompanies a demonstration of how much weight their boat can hold. After all the students presented, we will look at the rubric for the design, final presentations, and lab documents as a class We will have a class wide discussion of what kinds of things we saw across the board and brainstorm how we might address them. Students will take notes on what feedback they are getting from peers and their teacher. Lessons Learned and Reflection

+ Revise Prototype During their revision process I will bring in a community member that is knowledgeable of boats. Any feedback or ideas they are getting from the expert will be documented. With this new knowledge students will work on revising their design and rebuilding their prototype. They will have to make justifications for all of these changes in their lab books. Here I may challenge some students to only use 3 materials if they have already accomplished the specifications and constraints. Lessons Learned and Reflection

+ Test and Evaluate Revised Prototype Students will present their final products to the community and our classroom. They will give a presentation on how they informed their decision-making and also test how much weight their boat is able to hold. In their presentations they have to address their success at meeting the specifications and constraints of the project by giving concrete examples from their laboratory documents. At this step student will also turn in their lab documents to the teacher along with any sketches or drafts of their design. I will ask them to have a 10 minute discussion where they write down a 3/2/1 model: 3 things they learned 2 things they still don’t understand 1 question they still have Lessons Learned and Reflection
