The Raft Challenge by L2C is part of a series of activities that you can use for fun competition in your classroom. The Learn to Connect STEM Challenge series can be integrated into your instruction, implemented for fun end of the week activities, made part of a science club or used without the points and competition to engage your students in curriculum.
In this STEM activity the students will build background on rafts by examining density and buoyancy definitions, calculations and participating in an investigation that calculates the density of materials available to build the classroom rafts. The class will then break into teams to construct a raft with the goal to hold the largest mass. The rafts will be evaluated by placing weights on them in the classroom. You can make this aspect of the lesson competitive with the STEM Challenge Points or just allow the kids to enjoy the engagement and fun. Finally, students will be given a word problem to apply what they have learned to being stranded on an island.
This activity is three hours of engagement and problem solving that can be done all in one day or broken into 3 to 4 classes. The materials that are required for this lesson are simple. All you need is Ping-Pong balls, tape, Popsicle sticks, rubber bands, Styrofoam and water bottles. This activity includes a 7 page lesson aligned to the National Next Generation Science Standards along with pictures to make the activity even more clear. It also includes a 4 page Student Investigation Packet that will guide students thought the activity. Finally there are two versions of a Power Point so you can guide the whole group. One power point can be edited to meet your classroom's needs, while the other is in pdf format.
The Learn to Connect STEM Challenge brings science alive with fun, competition and real world application!
