Today I am sharing a sink or float chart because learning is always important!  I love to do fun science experiments, like learning about weather or the reason that things happen, with our kids- and they love to learn it, too!

We love to go boating, even in the fall (we live in North Carolina… this is one of the perks!) The other day our son asked us why the boat would float when there were so many of us on it.   We always go out with our family of six, my parents and my brother’s family of four, so his question made complete sense!

I explained to him how some things sink and some things float.  I knew that I needed to think of ideas that would work for everyone and that is when I came up with the sink or swim experiment. It is very easy and takes very little preparation!  So, when we got home, I got to work making some fun printables to go along with a lesson that I knew he would enjoy!


  • Just grab a container and fill it with water.
  • Gather your materials (seen on chart below)
  • Talk about what will sink and what will floatsinkfloat
  • Take guesses about what will sink or float
  • Try each item and then when you see if it sinks or floats, glue the appropriate picture onto the chart that says SINK FLOAT

Ps- If you are doing this experiment at home, let the kids gather items around the house, too.   Our kids picked Croc Shoes, a balloon, a necklace and more!  They had a blast and learned a lot at the same time (a win-win!)
