Moving on Water (STEM)

Olivia gets to go to the beach in the book “Olivia“. She builds sandcastles and gets a little sunburned. For our science activity, we decided to experiment with objects moving on water! Our challenge is this: Can you make a floating object move on water without touching it???


  • Tote
  • Water
  • Floating object (we used rubber ducks)
  • Optional: Blue food coloring (to dye the water)
  • Handheld fan
  • Cardboard or stiff paper
  • Rubber spatula


  1. Fill the tote about halfway full with water (optional: add a few drops of blue food coloring)
  2. Place the floating object in the water
  3. Tell the child the most important rule: You can’t touch the duck!! (or boat, or frog, or whatever you have around)
  4. Tell them the goal is to move the object from one side of the tote to the other. Remind them that they need to do this without touching the object.
  5. Show them the materials you brought: handheld fan, cardboard/stiff paper, and rubber spatula
  6. Allow the child the time to experiment and see if they can figure out how to move the duckling!
  7. We discovered: blowing with our mouths, fanning with the cardboard or paper, blowing with the fan, making waves with the spatula
  8. Happy exploring!
