Early this morning our little troop of students showed up to learn about Carbon Dioxide and Jesus- the Bread of Life.
First we started by talking about different chemicals, & chemical reactions.
I gave them each an empty bowl and had the following ingredients available:
- Hot Water
- Food coloring
- Dish soap
- Baking Soda
- Citric Acid
We took turns combining chemicals to see what the chemical reactions were with each one. These are some of the things we talked about:
WE ARE SCIENTISTS: During these activities we get to think and act like real scientists. We are going to compare things, ask questions and make observations using our senses.
BAKING SODA: Did you know? A long time ago people used baking soda to help their bread dough rise? They also used it just like we use soap today. Baking soda is used in lots of foods that we eat. It’s also used to clean space ships!
CITRIC ACID: Did you know that citric acid is a substance that is found in lots of fruits and vegetables. You can find it in lemons and oranges and other citrus foods. All acids taste sour, so if you were to taste citric acid it also would be sour. Citric acid is edible, and used in food, so that’s why it’s okay to taste it, but other acids can kill you or burn your throat if you taste them or EVEN TOUCH THEM!
CARBON DIOXIDE: The fizz that is created when we combine these items is called Carbon Dioxide. Carbon Dioxide is a colorless, odorless gas found in our atmosphere. Its chemical formula is CO2, which means it is one carbon atom bonded to two oxygen atoms. It is a waste product in our bodies and is also produced by burning fossil fuels.
YEAST: Yeast is the thing that make bread dough rise. Yeast is alive all around us in the soil, in the plants and even in the air. Yeast needs sugar to feed it and warm water to make it wake up.
They got to choose several different elements and combine them together to see what they could make, or what chemical reactions they could observe.
So while we were mixing and talking about all these different things we also took a ziploc bag with warm water, some sugar and some yeast in it and sealed it. We wanted to see what was going to happen to our bag when the yeast ate the sugar.
We also started a loaf of bread. We talked about How Jesus is the Bread of Life. And it’s because of Him that we can be forgiven of our sins and become perfect like him.
The kids were HAVING SO MUCH FUN mixing their potions and learning from the science experiments. This part lasted at least an hour before I told them we need to clean up. Once we had, I put the bread in the oven and took the kids into the other room to watch some movies.
We watched THESE MOVIES ON YOUTUBE:
- Carbon Dioxide Explained for Kids- 20 minutes
- How Does Bread Rise- 2 minutes
- Jesus is Our Daily Bread- 4 minutes
After the bread had finished baking, we checked on our ziploc bag to see what had happened. This is what we found!
I explained that as the yeast ate the sugar, it created a gas which was carbon dioxide. The carbon dioxide made the bag blow up and feel tight. I was going to throw it away, but of course the kids wanted to wait until it exploded on it’s own!
Once all our things were cleaned up we ate the bread and read stories in the sunshine!
