The first day back from last weekend, we spent the day reviewing for our test on Tuesday, the next day. This consisted of us, as a class, finishing up the study guide and white boarding the answers. This gave us a better understanding of how everyone else does a problem compared to how you, yourself does a problem. Particle diagrams were drawn to show us in a more clear aspect, how Avagadros Hypothesis comes jnto play. We were also asked to match and know the definition of a compound, mixture, element and pure substance. 
On Tuesday, we took the test itself. Now preparing for this test, I took all the information on the study guide and looked back on previous worksheets to study the night before. For the first half of the class we took the 2 page test and for most of the questions it was clear as to what the answers were, but for some I was still a little confused. We finished the test within 30 minutes, and immediately dived into the next Unit 5. The first thing we did was we were asked to guess how many packing peanuts were in a bag. The first thing I thought was "What is the point of this", but it soon became more clear. By measuring the mass of one packing peanut and by measuring the mass of the whole thing, we could find out how many there were in the bag! The total came out to 1,200 peanuts but most of the class guessed between 200-500.
For the rest of the week we focused on a worksheet that was titled "Relative Masses". This worksheet asked us to calculate masses of containers with nuts, bolts, and washers in them and compare them. We were then given questions that helped us analyze the masses in different situations. We ended Friday by white boarding the worksheet and having a class discussion. So overall this week has been pack full of intense studying and learning new things! My understanding of what is going on in class is pretty good when it comes to relative masses. I feel like more practice would actually help me get the full grasp of things, as there is still a part of me that isn't completely sure of the main idea. As we proceed to tackle the driving question, I will feel more comfortable and with the help if my table mates it will be great extra help. Most of that worksheet is just understanding the conversions. That is my weak spot as I still am unsure of the technique Dr. J taught us. I plan on working hard this week to come to really understand the concepts. Next week will lead to an elaborated lesson on Unit 5 and, I cannot wait to see what else we have to learn in this unit.
