# The Floating Egg Experiment: Free Worksheets

## The Floating Egg Experiment

It's always so much fun to do a cool science experiment with your kids.

I especially love doing egg experiments because even though they're mostly easy, they're also usually pretty dramatic.

The floating egg experiment is a good example.

We did this experiment as part of our ocean unit. Probably half the class correctly hypothesized that the egg would float in the salt water but everyone was excited to see it actually happen.

Here's the sheet (you can download it below) that I use with my class.

As a class, we fill out the sheet together.

I tell the kids that we're going to make an egg float in liquid. We read the hypotheses together and each child chooses the one they like the best.  I also always have them circle or underline their choice using a felt pen. You would NOT believe how many of my little scientists erase and change their hypothesis after the experiment is finished!!

After the hypotheses have been chosen, I give everyone a paper egg. They cut it out, write their name on it and decorate it, if they like. Then they glue the egg onto a large piece of chart paper indicating their chosen hypothesis.

I save all these chart papers and refer to them throughout the year. They're great to use in math lessons where you can talk about graphs, more than, less than, mode, etc.

Here's an example of what your class graph might look like:

The next step, of course, is to complete the experiment (as described in the worksheet above). After the solutions are made we carefully place an egg in each cup.

It's always so much fun to see the looks on the kids' faces when the egg floats in the salt water!

To finish up, the children draw a picture of their observations (I often model this on the board) and we talk about the results and the reasons why the egg floated (the salt water is slightly more dense than the egg).

If you'd like to extend the experiment a bit, watch this video. The "Crazy Russian" (that's what he calls himself) shows how you can suspend an egg in the middle of a glass (with water below and above the egg). It's very cool!

1. I love this idea! I am printing now and filing it away until we do our ocean unit at the end of this coming school year. Thanks for sharing.

4. I'm so glad you're sharing these great experiments and papers to go with. I am embarassed to say that I don't teach much science. But it's also not entirely my fault. The time schedule we're supposed to follow gives us 15 minutes for everything that's not math, reading, and esl. Seriously! I get some science in, but experiments like this seem short and sweet and might be something I could do more frequently. Thanks so much! And if you don't mind my asking, how long is your school day, and how many days are in your school year? We go from 8-2:15 175 days/ year ( during budget cuts, anyway) . Normally 180 days.

6. Hi Barbara -
That is so cool. I will have to file that away for our ocean unit. THanks for sharing. :o)
