Co-Op, Week 6

This week, my 7th and 8th graders are finishing up module 3. In class, we finished our module discussion, went over all of the questions on the module summary, and went over a few of the "On Your Own" questions.

They will be taking the quiz and test this week for module 3 in our online classroom (virtualhomeschoolgroup).

However, we ran out of time and didn't get to any of the experiments I had planned for them. Hopefully, we can complete several experiments next week.

My 5th and 6th graders are still working through module 2. In class, we finished discussing the first half of the module and went over "On Your Own" questions 2.1-2.8.

They were able to complete two experiments this week:

The first was called Drops on Coins. I handed out an assortment of coins (pennies, nickels, dimes and quarters) and each child had to guess how many drops of water they thought the coin would hold. Then they performed the experiment and we compared the actual results with their initial guesses.

The second experiment was called Baking Soda Bubbles. We slowly added vinegar to baking soda creating CO2 and then blew bubbles across the top to see the bubbles float on top of the CO2. This is because the bubbles are filled with air and air is less dense than CO2. Neat experiment!
