Science: Boat or Submarine?

Title:  Boat or Submarine:  
Scientists: Imaan and Hemani
Question: How many coins would the pan shaped clay hold?
What shape of container will hold the most weight?
A pan shape

Me and Imaan have chosen a shape which is a pan. We think that will work because we will make the pan a bit wide so the coins can fit and so the water can take time to come into it.

Container filled with water, modelling clay, old coins

Create a boat out of modelling clay.
I Fill the container with water.
Place the boat carefully onto the water so it floats.
One at a time , put coins carefully into the boat . Count how many coins are in the boat before it sinks.
Observation/ Analyse:
Me and Imaan made a pan kind of shape and it did float but didn’t hold much coins. Because me and Imaan made the shape kind of small.


That it can stay on water but the weight pushes it down. Just like having about 7 people on one little yacht. Also Mr Ford showed us a paper shaped as a circle which could hold 7 coins because the paper wasn’t breaking the water surface.


  1. Amazing work there Hemani I like the picture of the floating submarine.
    The best Part I liked about was the coins and the hypothesis great work keep up the awesome blogs.

  2. Wow Hemani your science is looking very cool. Did you have fun working with Imaan? I had fun working with Zach. Keep up the good work Hemani.

  3. Wow awesome job Hemani That looks amazing. I like that you put a photo of your boat with the coins in it. I like your writing as well.
    Well done Hemani.
    Keep up the good work.

  4. Wow Hemani,
    Great thinking.
    The pan shape is a great idea.
    Did you enjoy it?
