My Favorite Posts {DAY 6}--Floaters and Sinkers (Parts I and II)

For no particular reason than to simply take a break from blogging as I gear up for a fun filled  romantic getaway with my hot husband, I'm going to share some of my favorite posts from 2010.

Yes, I named it that just so you'd giggle.

Here's what to do.

1. Get a bowl or bin and fill it with water. You can use a bathtub, kiddy pool, or sink.
2. Randomly grab little things you don't mind getting wet (spoon, feather, sponge, pennies, whisk ... probably best to hide your cell phone about now).
3. Show your child how some object float and some objects sink.
4. For each item, have your child guess if it will sink or float.
5. Test your hypothesis!

To make this easier for younger kids:

Omit the guessing and just play in the water with toys that aren't usually water toys.

To make this harder for older kids:

1. Talk about mass and density. Need a refresher? Look here , among other places.
2. Blow up a balloon and talk about why it floats.
3. Put a plastic margarine container or toy boat in the water and add pennies or marbles until it starts to sink. Have your child guess how many of the heavier item it will take to sink the boat!

**NEVER, NEVER, NEVER LEAVE YOUR CHILD UNATTENDED WITH WATER**

PART II
So we accidentally came across this game last Saturday.

In the original floaters and sinkers, children guessed what items would sink in a tub of water and which would float.

This game follows the same idea but with air!

Here's what to do.

1.  Get a helium filled balloon with a long tail.
2.  Randomly grab little things that can be tied to the balloon (spoon, feather, sponge, pennies, whisk ...).
3.  Show your child how some objects cause the ballon to sink while others float with the balloon.
4.  For each item, have your child guess if it will cause the balloon to sink or float.
5.  Test your hypothesis!

To make this easier for younger kids:

Omit the guessing and just play with the balloon.

To make this harder for older kids:

Talk about mass and density.  Need a refresher?  Look here , among other places.  Talk about why the balloon floats.
