Who Sank the Boat?

What Floats in a Moat?
by Lynne Berry
Archie and Skinny are on their way to see the Queen and they must cross a moat to get to her castle. Archie, the goat, has grand plans to use a barrel of buttermilk to build a boat, Skinny, the chicken, is not convinced it will work!
Resources for What Floats in a Moat?:
Coming soon!
Activities for What Floats in a Moat?:
Build a Boat that Floats (English)
¡Construya un barco que flote! (Español)
Will a goat and a barrel full of buttermilk float in a moat?
Topics: buoyancy, engineering, problem solving
Activities To Do Together:
-
Discuss objects that float and objects that sink. If your child is not sure if an object will float or sink, allow them to experiment
-
Build a small “boat” together to see if it will carry small objects.
Questions for Mathematical Thinking:
-
Why didn’t the goat want to take the drawbridge?
-
Why do you think the first boat, the S.S. Buttermilk, sank?
-
Why do you think the second boat, the S.S. Empty, floated?
-
What was different about the S.S. Ballast that made it float AND sink? How do you know?
Vocabulary for Building Math Concepts:
mapped, measured
