Connecting to prior knowledge
Before reading
Look at the front cover illustration and title and have a class discussion about what the students know about floating and sinking. Make a list of things that they think float and sink.
Have the students do a think-pair-share about what they think will sink the boat and why.
Key questions
- The title is a question. How do you know it is a question?
- Why would the author make the title a question?
- Does it spoil the ending?
- What do you know about the size and weight of a cow and a donkey?
- Which would be more likely to sink the boat? Why?
During reading
The book introduces new characters other than the cow and the donkey near the beginning of the book. Ask students to revise their predictions now that they can see all of the animals. Discuss who is the heaviest and who is the lightest.
Stop each time Pamela Allen asks “Do you know who sank the boat?” and encourage students to revise their predictions after each animal hops in the boat.
After reading
After reading Who Sank the Boat? for enjoyment, have a class discussion about their initial reaction to the story and their predications as to who sank the boat.
Key questions:
- Were your predictions right?
- Was it a surprise?
- Why do you think the lightest animal sank the boat?
- Do you think that the story would have ended differently if the animals had got into the boat in a different order?
Exploring the text in context of our community, school and ‘me’
Exploring the theme of the text
In pairs students make a boat out of plasticine that can float. Experiment to see which boat in the class can stay afloat holding the most marbles. It may take several attempts for students to create a successful boat.
Key questions
- Which shape held the most marbles?
- Why do you think this was?
Rich assessment task
You will need a large tub of water and a collection of different objects of various sizes and shapes that float and sink such as a cork, eraser, plasticine ball, marble, tennis ball. Have students sort the items into two piles: those that float and those that sink. Take a photo of their predictions.
Now test all of the objects and adjust the two piles accordingly. Ask students to record their findings in the following observation table.
Sinking and Floating | |
Things that sink | Things that float |
I think these objects sink because . . . | I think these objects float because . . . |
Key questions
- Did the bigger objects float or sink? Why?
- What do the objects in each pile have in common?
