3 Questions September 1st 2017

1) What tasks have you completed recently?
- Recently I performed a density lab in which you weigh pennies and put them in order by date, then put them in a graduated cylinder with 30ml of water by 2s and measure the difference of volume to find their density. I also performed a activity where your task was to find the thickness of aluminium foil. In order to do so you had to measure the length and width of the foil and then weigh it. After recording those results I calculated the area, volume, and then find the thickness.
2) What have you learned recently?
- Recently I've learned many things. I learned how to find the density of an object by using water levels to see the amount of displacement that certain object creates. You just subtract the difference of volume by your initial volume. I also learned more about Significant digits and what rules apply to how many Sig digs you keep. If you are multiplying something you can only keep your lowest amount of Sig digs so for example if you were multiplying 25.364 x 26.1 you can only keep one Sig dig because the 26.1 only has one, so your answer would be 662.0
3) What are you planning on doing next to improve your understanding or reinforce your learning?
- I plan on practicing with Sig digs more so I can better understand all the rules and steps to get the correct amounts of Sig digs.

3 Question Blog 4/20/18

What have I completed lately? -I have completed worksheets and notes on endothermic and exothermic reactions, as well as a test, and a POGIL about Mole Ratios. What have I learned recently? -I have learned extensively about endothermic and exothermic reactions. Exothermic reactions release energy to make bonds (temperature increases), and in endothermic reactions enegry is absorbed and gained to break bonds (temperature decrease). I have also learned about Mole Ratios and what their purpose is when it comes to chemical reactions. What will I do to further my learning? -I will continue to ask questions in class, and be attentive in class. I will also study if I am struggling to grasp any concepts covered in class.

Exploring Measurement in the Food Industry

Our task for this lab was to collect mass information about various bags of Cheetos and use our data to determine the accuracy and precision of the bags. The purpose of this lab was to answer the guiding question, "Do you get what you pay for?". In this lab we used accuracy and precision to determine whether or not you get your money's worth when buying a small bag of Cheetos. On the packaging the bag states it's net weight is 28.3 grams. We used four different Cheetos bags to gather information. The first step was to find accuracy. Accuracy is defined as the net weight of 28.3g +/- .10g. We weighed the full bags of Cheetos separately and recorded the results, this is the gross weight. We then emptied the contents of the bags and weighed the packaging and recorded those results, this is the tare weight. After finding the gross and tare weight we then subtracted the tare weight from the gross weight and found our difference. The results are below. (G= Gross, T=Tare, D=

1. Recently I have completed a POGILs on Polyatomic atoms, Ionic compounds, and also Molecular compounds. I have also completed a foldable and a lab about the VSEPR model. 2. I have learned about naming molecular, ionic, and polyatomic compounds. Also i have learned about VSEPR. VSEPR stands for V alence S hell E lectron P air R epulsion theory. It means that since electrons repel each other they will be repulsed to the furthest possible distance away from one another within the limits of their bond. Unbounded electrons take up more space than bonded electrons. 3. To improve my learning I will continue to ask questions if I am having trouble understanding the material.
