 * Lab Skills Report**

This was a lab that tested and assessed our general skills in the lab. In the lab, we focused on finding the volume of liquid (looking at meniscus), the mass of irregular objects (using a triple beam balance), the volume of the irregular object (by putting them in the water and observing rise in the water), and the density of the irregular object (calculating it using the mass over the volume). For the data in this lab, we also had to calculate the error measurement, something that was new to me. We also tested our skills in using the temperature probes and logger pro by hooking the probes up to find the temperature of our hand and the temperature change of room temperature to the temperature of ice and graphed the findings in logger pro. Throughout this lab, we took pictures to document the experiment.

In this lab, I think that I was able to calculate mass, volume, and density well with relative ease because of my former knowledge of the subject from lab science in 9th grade. However, one thing that was difficult for me was taking the photos of each stage in the experiment because it turned out to be quite repetitive and took some time. Even though the photo taking was seemingly an easy task, we forgot at some parts of the lab and had to go back. Also I found labeling the photos as to avoid confusion seemed to be tedious. Even in my previous lab sciences I had used logger pro, I had not used temperature probes. This made it a good time to be exposed to the temperature probe device to practice using it in a dry run for later experiments and I learned how to use it with logger pro. I also learned the important skill of providing error measurements for recording data as we cannot be totally perfect in our findings. If I had to do this experiment over again, I would change it to enhance the learning process by using a camera to take pictures and going through the stations in order (e.g. 1, 2, 3, 4 etc.). This would making it less of a hassle to take pictures, therefore giving me more time to take down observations and findings and be more accurate (the lab got a little rushed near the end to finish). I would also want to have more time with the temperature probes, maybe having more stations using them as they were quite interesting to use and are useful throughout biology. Overall, I think this lab was great in reminding us of general lab skills (calculating mass and volume) and giving us new skills (error measurements and temperature probes).
