Extending this activity

  • -Compare the weights of straw, sticks, and bricks as used by the three little pigs. Have the child hold a brick in one hand and straw in the other. Model for the child how to use his or her hands like a balance (the heavier material makes the hand go down and the lighter material makes the hand go up). Repeat this process until all three materials are compared. Which is heaviest? Which is lightest? Why was the brick the best material to use?

    -Read the book “Who Sank the Boat” by Pamela Allen. Try to determine which animal will sink the boat when five animal friends of various sizes decide to go for a row.

Adjust for an older child

After testing the three materials in the activity, try additional materials that can stack such as Legos or dice. Use the same format of predict, test, and explain.

Adjust for a younger child

Even young children will enjoy this activity of building stacks and blowing them down. Reinforce that cotton balls and marshmallows are lighter than wooden blocks.
