I had them work in groups to determine which was the best deal and which was the worst.
Some were surprised with the results. We also decided that if you like Snickers you're willing to pay a little more to get them.
Friday we had Mad Scientist Day! This is always so much fun. Every year we schedule this day around Halloween. The kids are able to dress as scientists and we do science experiments.
We did experiments like Shy Blue and Drop by Drop to explore water surface tension. In shy blue we add color to the water and then drop rubbing alcohol into the water. The water looks like it is running away from the alcohol.
Drop by drop- we drop water on waxed paper and use toothpicks to move it around.
We also made some snow with Instant Snow from Steve Spangler.
The lava lamps were a big hit! Want to make one yourself? Fill a bottle 3/4 of the way with cooking oil. Then pour in water to top off the bottle. Add 10 drops of your favorite color food coloring. Do not shake the bottle! Then use an Alka Seltzer tablet. Break it up and drop in a small piece. It creates a lava lamp. You can continue adding pieces of the tablet until it is gone. Be careful if you put a lot in at one time. Make sure to open the lid to release pressure that builds up in the bottle.
We ended the day by walking on eggs. I even gave this a try! Did you know you can walk on eggs? As you can see they had a great time doing this.
STUDENTS: What was your favorite experiment during mad scientist day? Explain what you did and why you liked it so much.
