My 10 year old, Beau, and I were studying Science yesterday. It's one of his favorite subjects. I'm not really a Science kind of person. The things we do for our kids :-) Anyhoo, the Abeka textbook called for creating a water lens to magnify things. It was so simple and so much fun. All we did were cut two holes, one on each side of a bucket(just large enough where he could put his hands through), we then covered the the top of the bucket loosely with clear plastic wrap, secured by a rubber band, we then put water on the plastic wrap until it began to sag. We placed a lot of different objects in the bucket through the holes and looked at them through the water. I thought it was really neat and my 10 year old kept trying to see what object he could magnify next.
Also, here's an easier and less expensive way to make a water magnifier
What You Need:
•One 2 by 3 inch piece of cardboard
•One-inch square piece of thin clear plastic
•Pair of scissorsIn third grade, children are starting to use magnifying glasses and microscopes to see how small things can be magnified to appear larger than they really are. Here’s an interesting activity that will enable your child to make his own magnifier out of a drop of water!
What You Need:
•One 2 by 3 inch piece of cardboard
•One-inch square piece of thin clear plastic
•Pair of scissors
•Tape
•Water
•Spoon or medicine dropper
•Newspaper

What You Do:
1.Cut a dime-size hole in the middle of the cardboard.
2.Set the clear piece of plastic over the hole, and tape it down. Tape it around the edge without covering the hole. Fold each end of the cardboard down 1/4 inch.
3.Dip the tip of the spoon in the water. Hold the spoon directly over the center of the hole, and let one drop of water fall onto the plastic.
4.Set a piece of newspaper with printing, on the table.
5.Tell your child to carefully lift the magnifier and set it down on top of the paper.
6.Your child should then look straight down through the top of the water drop; the printing on the paper will appear magnified!
If the writing on the paper appears blurry you must focus your magnifier. Put the tip of your finger on the cardboard just to one side of the hole. Gently press the cardboard down this will cause the cardboard to bend so that drop will be moved down closer to the newspaper. You should be able to see a sharp image of the print. As an extension activity encourage your child to examine salt, sugar, leaves, etc.
