GRADE 3 FORCES PROJECT: Build a Boat! Our Science unit on Forces will include designing, building, testing and presenting a floating boat that carries a load of 100g and moves by way of a force (wind, magnetism, propeller of stored energy, etc.). I ask that the students bring in materials from home that may be useful in building a boat. If you could set aside a box at home, to drop potentially useful things into, your child can bring in the whole box next week. Anything they don’t decide to use may be desirable to another builder. Plus, the box will help contain everyone’s building materials nicely. The boat will be constructed at school, in class during the weeks of January 16th and 23rd. Parents may help students plan the boat at home but all construction and design work must be done at school. I encourage a home-school learning connection, but the materials should come to school unassembled and nothing pre-cut or pre-fabricated. Students will do this in class. The boat can be built with everyday household items such as: yogurt, margarine, juice containers, lego, plastic bags, paperclips, tinfoil, straws,cork……. The boat needs to be able to hold a load of cargo and should be made out of at least three different materials. The activity is based on specific expectation in the science and technology curriculum, which states; identify forces as pushes and pulls, identify different forms of energy and suggest how they might be used to provide power to devices and create movement, record observations, findings, and measurements in writing, drawings, and through oral presentations, use technological problem-solving skills, and knowledge acquired from previous investigations, to design, build, and test a structure that involves interactions of forces and movement. Please note that I will extract several assessment pieces from the assignment. These assessment components will stem from the project: 1) Students will reflect, based on the testing of the boat, how they might make changes. (oral & written assessment, conference with the teacher) 2) They will make an oral presentation to the class describing and explaining the construction of the boat. (oral assessment) 3) They will test the boats by loading them down with weights such as pennies or a mass of 100g or a figure of comparable weight.
