Even though this was the last week I still continued to teach. I want to reflect on one day this week though. I wanted to try out another kit this week and this time it was a DNA extraction lab. I read over the instructions and went through the materials to try and prepare myself during the days leading up. Unfortunately, there was only enough materials to do this lab one day and so I could not test it out before hand. That meant that I had to go in to this day without knowing for sure if the lab would be successful.
That morning was very hectic, trying to get everything prepared. I had to prepare an onion extract before all of my classes and scrambled to do so because some things did not go as planned. For example, the hotplate I had would not get as hot as I needed it so I had to run around to find another one.
Eventually, I got everything prepared and ran through the lab with my first period class. Ultimately, it did not work very well but we kept trying. The next class we tried again and once again it did not work. Based on previous experiences this year and lessons that I have learned I prepared for this and had a back up plan. I had some practice worksheets for the students to complete so while we weren't able to complete the experiment, the day was not a complete waste.
