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.”
We had a Science Lab birthday party a few weeks ago. There is so much to share that I thought that I would just do a few things at a time.
We did several experiments. This one is one that both of my older daughters have won ribbons for in science fairs.
Yeast Loves Sugar:
Each child took a water bottle and put one teaspoon of yeast inside. They then put in 1/4 cup of warm water. They then had to decide on something else to add. I gave them the information that yeast is a fungus and that it loves sugar. They ran all over the house finding things to add to their yeasty bottle. They had to add 1 tablespoon of whatever they chose. We then swirled the bottles around and placed balloons over the mouths of the bottles. I had the children write down which one they thought would blow the balloons up the most. We watched over the next few minutes and hours as the balloons inflated with the byproducts of fermentation. It is one of my favorite experiments because they really get to see the effects and they also learn that some of the things that they thought were full of sugar really were not and vice versa.
The sugar bottle ended up the largest in the end. I saw it wasn’t as big as it should have been and realized that the child forgot to add the water. Once I added the water, it quickly surpassed all the others.
