When Soren woke up, he even added on a few sticks and mallows.
I asked her, "Why do YOU think we spread salt on an icy sidewalk? Can you guess?"
She guessed, "The salt melts the ice?"
We decided to see if this were true. I said, "We'll see if ice added to water makes it harder for the water to freeze."
I explained (after quickly Googling this to make sure I didn't spread misinformation) that salt speeds up the melting of the ice because it can make ice melt at a lower temperature. Salt also helps keep the ice from re-freezing.....which we saw when we put the salt water in the freezer!
I later came across an experiment where kids can use salt to "glue" an ice cube to a string, and then lift it up. This is exactly the sort of thing that sets my geek heart aflutter.
(I may be a geek, but I'm not a science whiz, so preschool science experiments may be as good as it gets for me. I plan to enjoy this while it lasts, and before I become unable to comprehend any of it.)

(as seen on Ordinary Life Magic)
You will need:
(Borax is a natural cleaner....you can find it at most grocery stores, Wal-Mart, etc.)
Use a small piece of pipe cleaner as a "hook" for dangling the ornament over the size of the jar. (This can be removed later.)
On the stovetop, heat some water....for each glass jar you have, you will need 1 cup water and 3 Tbsp. Borax.
Just heat the water until it is pleasantly warm. Stir in your Borax til dissolved.
Nothing will happen for the first hour or so. Distract your concerned little crystal artists. A couple of hours later, when you peek in at your ornaments...magic crystals will have begun to grow! Over the course of 24 hours, your ornaments will be nicely covered with beautiful "snow" crystals. Remove the ornaments after about 24 hours -- they will feel dry to the touch almost immediately. Hang them on the tree, in a window, or somewhere they can sparkle!
Nora went on a binge....the good kind. She couldn't stop painting cinnamon ornaments! Here she is, proud of her finished product. (And while it may look like I kept her up until midnight painting, rest assured it was only around 5 p.m. Winter darkness!)
1 cup cinnamon
1 cup applesauce
2 Tbsp. white school glue
(Since this requires about 3 containers of cinnamon, get the cheapest you can find.)
Start by mixing your ingredients in a bowl:
Use a straw to make a hole in the top of each shape, if you plan to use them as ornaments.
Let them dry for a couple of hours. You can varnish them with any craft varnish. I had some gold glitter glue on hand, so I thinned that out and we just gave them a top coat with that; it acts like a sealant and added SPARKLE!
When they're fully dry, thread some pretty ribbon or embroidery thread through the hole, and you have nice little, delicious-smelling ornaments to give anyone who comes your way.

You will need:
a plastic 2-liter bottle
Here's how to make your own lava "lamp":1. Fill any cup, like a large plastic party cup, with water.
2. Add food coloring of your choice until you have a nice, vibrant color.
3. Take a nice, clean 2-liter bottle. Fill it a little over halfway with vegetable or canola oil.
4. Add your cup of colored water to the oil.
5. Add more oil if necessary, to fill about to the top.
6. Put the cap on your 2-liter bottle. Gently tilt the bottle onto its side. What do the oil and water look like now? (We drew a picture in our workbook, for future reference.)
If you leave your lava lamp out for any length of time, you will notice that the oil and water molecules separate almost completely. Interestingly, the water is denser than the oil, so it will sink to the bottom; the oil will rest on top.
(Density is how much an object weighs compared to the space it takes up. So if you have the exact same amount of water and oil -- say, 2 liters of each -- the water will weigh more than the oil. It is denser.)

Here is a simple way to make tissue-paper collages....
1) Take a piece of cardboard and wrap the front of it with aluminum foil.
3) Mix a small bowl of diluted glue and brush it over the surface of the foil. Lay pieces of tissue over the foil in any arrangement you wish. Keep layering tissue, brushing a layer of glue over each piece to hold it down.
