Unit 4: Thinking Like a Scientist Theme 8: Does It Sink or Float? http://farm1.static.flickr.com/25/49670198_ba69cd9a1a.jpg

sink- when something goes to the bottom when it is in water http://wweadam.files.wordpress.com/2008/08/left-side-pearl.png?w=269&h=264&h=264 If you drop a rock in water, it will sink.

heavy- something that weighs a lot An anchor is heavy, but a feather is not.

collect- to gather things together http://www.looseleafnotes.com/notes/optional/usbshells2.jpg You can collect shells on the beach.

predict- to use facts and ideas to guess what will happen http://iphonewallpaperscript.com/demo/thumbs/leaf_on_water-t2.jpg Do you predict a leaf will float or sink?

study- to read or look at something in order to learn new information http://www.thedailygreen.com/cm/thedailygreen/images/GF/water-spider-0808-lg.jpg You could study bugs that float on water to find out more about them.

Good swimmers know how to float on water. float- something that stays on top of the water when it is in the water http://www.activities4kids.com.au/images/swim-floating%20on%20back.jpg Good swimmers know how to float on water.
