Did you know you can make your own carbonated water without dry ice?  It’s so easy.  All you have to do is mix water, juice, or any other drink, and add equal portions of baking soda and citric acid.  We mixed it with Tang a few months ago and it was tasty.  It changes the […]

Ride on the Magic School Bus

My kids are CRAZY about this show.  We bought the complete series for Christmas, and bar none, it was their favorite item.  They prefer this show over any of our Disney movies.  And because I like it too, I let them watch it.  Well, it’s permeated our family life. How do I know? My two-year-old […]

Mommy, what happens to fish in the winter?

Well, it’s a good thing that ice floats, or they would all be dead.  Luckily, what happens is that they just keep swimming and and living during the winter as they do in the summer, but the lake freezes on top.  Yesterday we illustrated this with a tasty treat, albeit with foods containing food coloring […]

Snow density

Here is a simple experiment that we adapted for our preschooler.  When we had a blizzard last December, in addition to making snow cones with juice concentrate, we filled our graded measuring cup so that there was about 2 cups of unpacked snow.  We talked about how snow is made of water, and that when […]

Volcanoes

Ah yes, the classic science experiment of pouring vinegar over baking soda for a chemical reaction. This is one of my children’s favorite activities to do. I have a pie tin set aside to catch the results, and a baby bottle that we use as a volcano.The volcano was actually a tool that I used […]
