Dive In

Hey guys, I know the class is over and people probably wont' be checking blogs or other people's blogs as much, but Joe helped me A LOT the other day to put together a lesson on Dalton's Law of Partial Pressures that my observation teacher let me teach this morning. I modeled it after Eugenia's ISLE cycle and I thought it went well for the most part even though it was Friday. It's a total of 12 slides and I was able to go through all of them within the 43 minute period. I've also attached a worksheet for the kids to do for homework to follow up on what they learned in class. Students struggled a little bit just cause it was a different learning environment for them and this was my first time doing it, but overall I think it went well and so did my observing teacher. Hope it helps for anyone who has to teach Dalton's Law. You will find that this has applications in scuba diving among other area, and a topic scuba divers should be familiar with...so don't be afraid to get your feet wet with your students and DIVE IN!

Technology Application 2: A Lemon Battery

In this activity, students perform an application experiment using food! Ever hear the old saying, "When life hands you a lemon, make lemonade!" Well today, when you hand the students a lemon, they are going to make a battery. Students will design a battery with a lemon to try and light a bulb. They will be able to use Vernier to measure the voltage. This is a fun activity after going through electrochemistry and how a battery works.

Journal 14

Today in my observation, my teacher took her students to the computer lab to do use a computer animation to study gases. The students had to build the apparatus themselves and then determine the pressure at a fixed volume when different masses were put on top of a piston in a closed container. The students seemed to like it and it gave them a chance to experiment with different gases. Friday will be my last day there and my teacher is letting me teach. I will be covering Daltoon's Law of Partial Pressures, so if anyone has any suggestions, I am all ears!
