►What we did 2012-13
Play Quizlet. Just scroll down and click on Physical, then scroll to find the Module you want.
Experiment 1.1, Atoms and Molecules We did our first Apologia science experiment today from Exploring Creation with Physical Science. (yes, we just started this book! ...but that's another story)
We were showing that molecules are made of two or more atoms, and we made a molecule! copper hydroxycarbonate.
The molecule copper hydroxycarbonate is made from the atoms hydrogen, oxygen, carbon, and copper.
We had cousin C strip about ½ inch off the ends of 2 pieces of insulated copper wire. Cousin A mixed 1 tsp. baking soda in a glass of water until it was clear and totally dissolved. Umm, I think Rebekah got out the baking soda, ha. They all (it kept falling apart) taped the ends of the wire tightly to a 9-Volt battery and put the loose ends into the baking soda water. (without letting the ends touch!)
It immediately started bubbling, and very soon the loose end of the wire that was connected to the positive end of the battery began to turn sea green. The green substance was the copper hydroxycarbonate.
Eventually the water turned green too. We let it bubble for 10 minutes while they wrote down the first parts of their lab reports, then looked at the copper hydroxycarbonate that had formed on the wire connected to the positive end.
The atoms that make up copper hydroxycarbonate came from different sources. The carbon atom came from the baking soda. The hydrogen and oxygen atoms came from both the baking soda and the water (H2O). Copper was the other atom needed.
The energy in the battery broke down some of the molecules of H₂O back into hydrogen and oxygen, which caused them to bubble because hydrogen and oxygen are gases. This allowed these individual atoms (not molecules now) to be linked with the copper on the end of the wire and the carbon that was in the baking soda, creating the molecule
copper hydroxycarbonate.The kids really enjoyed being able to do this together.
Now they just have to write the observation and conclusion to their lab reports. =)
If I got anything wrong, let me know. I'm just learning this right along with the kids! =D
Great job, everyone!
ReplyDeleteYou are right, Marty -- the teacher learns as much or more than the student. I would love to be your student, though!
I remember watching Mr. Wizard on Saturday mornings when I was young. He would do all kinds of experiments like this and made learning so much fun.
Great job, Mrs.Marty Norman!Looked like a lot of fun, and you done a great job explaining it too!~Sharon
ReplyDeleteI really have always been a little fascinated with science, but never really understood it.
ReplyDeleteMaybe with this Apologia science, I'll finally be able to!
I'm reading ahead and really liking this! =)
Mama, you can come join our class anytime!
Sharon, you too! Bring the kids!
Um... call me first, lol.
Fun, fun! I really liked this book. The experiments were a lot of fun.
ReplyDeleteYou are doing a great job!
Thanks, Michelle!
ReplyDeleteI really love this book. =)
If you ever see anything I posted that's not quite right, don't hesitate to let me know!
Wow I'm so glad you found me. You all look like you are having a blast=) It's always fun to see what someone else is doing. I'm sure I'll be back here for inspiration this year. Thanks for all your hard work in documenting all this. I wish I was better about it but I tend to be a sporatic blogger.
