So right now in preschool we are learning about Animals in Winter.....I don't know why I always have so much fun with this theme!!

Animals in Winter

Anyway, today for a science experiment, we discovered what it would feel like to be a Polar Bear swimming in the icy water (kind of). First, have each child put their bare hands in a bowl of freezing ice water. We like to count and see how long they can hold it in there (great counting practice). Every class I always get at least a couple of brave souls who leave their hand in there as long as they possibly can - I always stop them at 30!!

Who knows how long they would actually leave it in there - crazy kids!! Then, take a rubber glove and have one child make a fist and have them put there hand in the glove (obviously you aren't going to have them put their fingers in the finger places :). And cover that child's hand with shortening. I just plop it on until the whole fist is covered....I use quite a bit. Steve Spangler Science. Pour enough milk in the dinner plate to completely cover the bottom to the depth of about 1/4 inch.

Allow the milk to settle. Add one drop of each of the four colors of food coloring - red, yellow, blue, and green - to the milk. Keep the drops close together in the center of the plate of milk. Find a clean cotton swab for the next part of the experiment. Predict what will happen when you touch the tip of the cotton swab to the center of the milk. Milk is mostly water but it also contains vitamins, minerals, proteins, and tiny droplets of fat suspended in solution. The secret of the bursting colors is the chemistry of that tiny drop of soap. The molecules of fat bend, roll, twist, and contort in all directions as the soap molecules race around to join up with the fat molecules. Try adding another drop of soap to see if there's any more movement. Science Fair Connection: The Color Changing Milk activity is a great demonstration of what happens when you combine dish soap and milk. Density Tower - Magic with Science.

Start your column by pouring the honey into the cylinder.

Now, you will pour each liquid SLOWLY into the container, one at a time. It is very important to pour the liquids slowly and into the center of the cylinder. Make sure that the liquids do not touch the sides of the cylinder while you are pouring. It’s okay if the liquids mix a little as you are pouring. The layers will always even themselves out because of the varying densities. The same amount of two different liquids will have different weights because they have different masses.

To test this, you might want to set up a scale and measure each of the liquids that you poured into your column. Density is basically how much "stuff" is smashed into a particular area... or a comparison between an object's mass and volume. The same goes for the small objects that you dropped into your density column. In the materials, we had you grab a bunch of miscellaneous tiny objects. Why do you think these two phenomena happen?

It will be a classic for us. I am even thinking of taking it on the road this fall when we camp on an primitive island - if I can sacrifice the ice. This is so simple. The biggest tips I would like to share are: 1. 2. 3. 4. Kids in Growing Plants. Growing a cutting can be fun too.

Kids in Growing Plants

I recommend Fuchsia's or Geraniums as they are easy to grow. Firstly get a cutting by taking a section of non-flowering stem and cut it free with a clean knife from just below a leaf joint. Remove the leaves immediately above the cut. Get hold of a thin sheet of polystyrene and punch some small holes in it. Thread the stems of your cuttings though the holes so the remaining leaves are on the top surface of the polystyrene. Obtain a tray or tub suitable for holding water and fill to virtually the top. Float the polystyrene complete with the cuttings on top of the water, or if the jar is small enough you can balance the cutting within the water using its leaves to suspend it on the neck of the jar, and without the need for polystyrene (as per the right hand image). Change the water every couple of days, and before too long your cuttings will produce a root system. Suspending Water Without a Cup Trick - CollegeHumor Video - StumbleUpon.
