1) Fill an ice cube tray with water and add food coloring in lots of pretty colors. Stir to mix, and set your tray outside in the cold world until it is well frozen.
The water in your pan must be VERY cold -- set it outside or in your freezer for several minutes. Otherwise, when you add the ice cubes, they'll melt too much.
3) Alright, when the water is cold, pour in your colorful frozen ice cubes.
5) Tie yarn or rope through the hole, and hang your suncatcher outside, where your kids can see it from the window. It makes a beautiful and unique ornament!

We'd been studying weather and water; we started talking about air, too. We decided to make our own dried apples.
Slice 4-5 Granny Smith apples into rounds. I sliced them again in half.
Soak in pineapple juice for a day (prevents too much browning).
From "Science Clarified": Here's an explanation of why the water evaporates from the fruit.

Whenever it rains, Nora cries, "MOM! We need to put out the rain gauge!" It's exciting for her to see how much rain we got, although she always expects a lot more. I guess one or two inches of rain doesn't really LOOK like much to a 5-year-old!
One night, we set out some pans of water with a few toys in them. The kids' mission: to rescue their friends from the ice! It took a considerable amount of work!
We even tried drilling:
It had been a couple of days since the snow fell, so we made this on crushed ice instead. It's easy:
-- Heat a half-cup or so of maple syrup to boiling. Then, pour it over ice or snow. A couple of minutes later, it will have hardened somewhat into chewy strands that taste just like, well, maple syrup. Yes, it looks a bit like boogers on ice, but the kids thought it was fun and tasty.
We put a bowl of water outside for an hour and a half to see.
Nora wrote up her hypothesis, and she was right: "From the top, down!" she cheered. We talked about how this allows fish to survive all winter.
