Campbell's giant can






 My step-by-step thinking process

Given the size of the actual Campbell's Soup can (of normal size) and the height of the bike in the photo (my own medium-sized hybrid bike), what are the dimensions of the volunteer fire department's water tank? What is its volume? Does it hold enough water to put out an average house fire?

I started asking myself:

1.      What are the dimensions of a standard Campbell soup can? I would Google it

2.      Do I remember the formula to calculate the volume of a cylinder? I would Google it

3.      What are the dimensions (length and height) of Susan’s bike? I would Google it

4.      How can I use Susan’s bike to estimate the length and diameter of the water tank?

5.      How much water does an average house fire need? google it

 

I am so tempted to plug the picture into ChatGPT and ask for the volume of a water tank from the fire department in Hornby Island. I usually enjoy observing neural networks at work!

 

I also noticed my brain was asking questions around the piece of art that wouldn’t necessarily help me solve the problem:

-          What is the water tank made of? Why does it look crooked? Is it a visual effect?

-          Why are the tanks placed horizontally on the floor and not vertically at the height?

-          How far are these tanks from the firehouse? Do they need to pump the water?

-          Is this a good question to use for the “Thinking Building Classrooms”?


...to be continued.

  1. Adore the questions and the insight into your working process. How could this look in the classroom for you?

  2. I would definitely use this kind of problems to ignite the thinking in the room, encouraging students to take risks in estimating or finding different paths to find a solution of mathematical problems.
