Lave Lamp

Warm water was placed in a clear glass vase first. Then we added oil. The food coloring was added next. I didn't get a picture before we started, so this was the second batch of food coloring added. After you put in the food coloring, you sprinkle salt on top. As the salt sinks to the bottom it pulls the food coloring drops down with it. Causing them to mix with the water. It was a really neat effect. There is about 3 inches of water, 1/3 cup of oil, then food coloring as desired.

Bubble Popper



This doesn't look like much via the picture, but it was fun. We mixed vinegar, water, and baking soda together. The bag was then sealed and placed in the bath tub (I wasn't sure what kind of mess we would encounter). We waited and waited and waited some more. Finally, when we thought we couldn't wait any longer it exploded. The girls loved it--laughed and giggled--who does that in science class and gets a high five!! This was a pretty cool experiment to do. Ours took a little longer, because I used a quart bag instead of a sandwich size bag and didn't adjust the amount of ingredients used. A lesson learned :)

Milk Magic

Milk Magic
I found this idea on almostunschoolers.blogspot.com. I thought it sounded interesting, so we gave it a go. All you do is pour some milk in a shallow bowl or dish (we used a salad dish). Add a few drops of food coloring--I think we used red, green, blue, and yellow. Place a q-tip in liquid dish detergent and gently touch it to the milk and food coloring--be AMAZED!! The colors danced around the plate like magic (hence the name of the project). My oldest, who is only 5, was too busy doing other things to come join us. As soon as she heard the ooohhhsss and aaaahhhss, she quickly came over to inspect our discovery. She ended up loving the experiment too.
