Introduction
Imagine you have been given the task of building a boat. Do you know what materials sink? Do you know what materials float? What makes some objects able to float in water and other objects sink?
These are all important questions that you will need to know the answers to because you have been hired on to work for the new and upcoming boat manufacturer in your area.
You're job will be to find the best materials to make your boat competitive with existing companies.
Click on "Task" to begin.
Task
Your task is to create a list of materials which you think will allow your boat to float for 60 seconds, while holding 3 crew members (counting bears).
Your research on materials can all be found here on WebQuest.
You will then be tasked with building a boat of your own!
GOOD LUCK!!

Process
Step One:
Enjoy this story "Who Sank the Boat?" by Pamela Allen
Step Two:
Please watch the video to learn about sink and float.
Step Three:
In your STEM Journal, PREDICT what you think is going to happen when we put it in water. Will it sink or float?
1) Scissors
2) Pencil
3) Crayon
4) Paper Clip
5) Key
6) Cube
7) Bowl
8) Pan
9) Cork
10) Rock

12) Egg Carton
13) Sponge
14) Marble
15) Dice
After you have made your predictions, click the "Evaluation" bottom.
Evaluation
It is time to show what you have learned! Create a list of materials to begin building your boat.
Remember...
You are going to be creating a boat that must float for 60 seconds, while holding 3 crew members (counting bears).
Conclusion
You have almost done it!
