How to Build 



Problem: Can I build a tank that can hold 100g and travel 50 cm?


Hypothesis: I think I can make a tank that can hold 100g and travel 50cm.


Materials and Method:

Step 1:I drew a plan.

Later when you are building you can switch you plan like I did

Step 2:gather your materials – 

4 little ping pong size balls

A few pieces of cardboard tape

Skipping rope handles

Corduroy material 


Bamboo sticks 

Step 3: Make the float and test it.


Results: My hypothesis was right. My float held 100g and traveled 50cm down the ramp.

  1. Hi Fen! Great post! I love how you turned your tank into a float! Your steps to follow were very clear as well. Do you think that if you did the challenge again that you may change anything? What if the ramp was higher? Lower? What do you think that would do to the distance it could travel! You’re always up for a challenge and I can’t wait to see what you do next! Great work!
