We did a couple of other experiments. We did the dancing gummy worms experiment. It was kind of a dud. We also did the Mentos and Diet Coke geyser. That was lots of fun!! Most of the adults had never seen it before, so it was really a treat for them. They also did the turn an egg shell into mercury glass. It was really tough and took forever to do. The ones that had the patience, did get to see how cool it turned out in the end. I also had prepared slides for them to look at under the microscope.
We played trivia of course. I had educational posters up all over the house. They were cute decorations, and now make their home in the school room. Back to trivia, most of the answers could be found on the posters.
We also made cells from cookies and candies. A few of them turned out really good!
I made chocolate lab rats, fossil cookies, petri dish jello, strawberries, pineapple, and grapes made up the fruit tray. We had a cheese tray. We had chips and guacamole and potato chips. We had tuna and chicken salad as well. I made educational signs for the foods and hung them by them.
I made a cake with sprinkles and a jello petri dish.
The invitation was from Etsy shop ohbejoyfulshop.
It was such a fun party!
One of the other experiments we did during the party was Exploding Elephant Toothpaste. It is a very easy experiment; but it does require some ingredients that you may not have on hand.
12% hydrogen peroxide (I got mine from Sally’s Beauty Supply)
We did this experiment outside. Each child was given safety glasses and gloves to wear. I gave each child their own bottle. I had them choose a color to add to their bottle. Using the funnel, they then added 4 oz. of hydrogen peroxide. After adding a drop of dish soap, they gently swirled the bottle to mix the ingredients. In a small cup, they then added a packet of yeast and warm water. Then the fun was really about to begin…
They added the yeast mixture into their bottles and voila…Exploding Elephant Toothpaste.
I had the bottles in a deep disposable metal pan. The children could feel the heat from the exothermic reaction that had been created.
Steve Spangler explains the science behind it. “The yeast works as a catalyst to release the oxygen molecules from the hydrogen peroxide solution. The oxygen-filled bubbles, which make up the foam, are actually the remainder of what happens when the hydrogen peroxide breaks down into water (H2O) and oxygen (O2). The bottle will feel warm to the touch because this is an exothermic reaction in which energy, in the form of heat, is given off.”
Our elementary science this year covers a broad range of ideas. I decided to do at least one science experiment a week from a couple of Steve Spangler’s science experiment books. Last week, we did an experiment that demonstrated Bernoulli’s Principle. For this experiment you’ll need a hairdryer, toilet paper roll, and a ping pong ball. He performed this experiment on the Ellen Show. My children loved doing it over and over. I think it really did help them understand the idea of lift that makes an airplane able to fly.
