DIRECTIONS:
Use the tape and straws (or your chosen materials) to build a raft that can hold the heaviest load.
Fill a container or the sink with water and test your raft to make sure it floats.
Put the small container on your raft and slowly add small objects (Lego/coins) to see how many your raft can hold.
Can you improve your raft design so that it can hold a heavier load?
