Meal Conversion Project

I have rather enjoyed this project. It involves good food and it isn't overly complicated. The dish I am planning on bringing is gooey butter cake. This recipe is rather simply for being so delicious and dosent have many conversions to be made. This project has ingrained in my mind that 1cup=.473dL. Also, teaspoons=.203 mL. If I am ever in a different country and they ask me these metric conversions, now I have the answer. I hope that the rest of the class brings in even better treats!

Unit Test

After 2 weeks of learning information, both new and old, I successfully completed the test. I haven't received my grade yet but I am quite nervous. Although this chapter was easier compared to most, I'm worried I might have messed up my conversion rounding. Hopefully I didn't but being the realist that I am I expect the worst. I need to prepare more for these tests . Our class should have study sessions after school. There's always next chapter to improve!

Uncertainty in Measurement

Accuracy=proximity to true value(equipment)

Proximity=proximity of several measurements to each other(human)

Significant rules

RULES

0.004004500

-before decimal(insignificant)

-zeros before numbers hold place(insignificant)

-all non-zero integers(significant)

-trailing zeros(significant)

-zeros between integers(significant)

All numbers written in scientific notation are significant
how scientific notation works

Addition/subtraction 

Number of significant figures in the result is same as in the measurement with the smallest decimal places

Multiplication/division

Number of significant figures in the result is the same as in the measurement with the smallest number of significant figures

Matter notes

Whats the Matter with you?
•solids have lowest Kinetic energy; gases have highest

•CHANGE IN STATE IS PHYSICAL CHANGE

•change in temperature=change in Kinetic energy

•no temperature change=potential energy change

Classifying Matter

•Mixtures are homogenous(cannot see different components)or heterogenous(different components)

•pure substances are compounds(can be separated into similar substances) or elements(cannot be separated)

Changes of Matter

•changes either physical(no changes of matter) or chemical(change make new substance)

Seperating

•filtration

•distillation

•chromotgraphy

What Chromatography is?

Measurement pre-test

Today we took our pre-lab quiz for this unit. It consisted mostly of significant numbers and how to correctly find mass/volume. This chapter seems easy enough and relatively self explanatory, with it being centered around correctly reading measurements, something we've already learned. Hopefully, with a lesson on significant numbers and a formula worksheets I will easily be able to do well on the end of quarter test.
