In this lab, our purpose was to discover the properties of acids and bases, to develop methods for identifying acids and bases and also to classify unknown solutions as acids or bases. Our group first had 3 plates with little holes in it where we would place our 5 different indicators into (Phenolphthalein, Bromthymol Blue, Methyl Orange, Red Litmus and Blue Litmus). Then we would put a drop of each solutions into the indicators to see what colors they change to. These colors should match up to which category of the pH scale it should classify in, Acidic, Basic or neutral. This lab helps us understand how we can classify solutions we don’t know what pH level they belong to by simply testing them with the indicators. There were 3 unknown solutions and by simply adding a drop of each of them to the indicators, we can quickly discover if they were acidic, basic or neutral. This lab is importance to the outside world because so many of these solutions like Aspirin, oven cleaner, vinegar etc. can be found in our daily lives. Acids and bases are found in nearly everything like food and the environment therefore learning about bases and bases gives us an understanding of how it plays a role in our daily lives.

This was a project where we were studying motion and graphing the displacement for ever 5 seconds for 30 seconds. Our group decided to do a toe to heel movement and we would put a tape on the heel every 5 seconds to measure the distance between the initial position and the final position. It was very interesting because i found out that there were different changes in displacement in each interval of our trials because it all really depend on the person who is doing the toe to heel. They could have been faster or slower between each interval which would change the displacement. We learnt that the graph that we drew after we recorded everything, tells us about the different movements because when you look at the slope, the displacements are not in uniform motion so we knew that there were different motions and not a similar motion between each interval. It was really interesting graphing our data and results and seeing the difference of motion.
