My Science Homework

The last several days of science have been filled with math - from scientific notation to significant figures to today’s quiz over the two topics. Today we finally wrapped up that portion of this unit and moved on to defining accuracy and precision. By tying these terms in with the use and importance […]

For the second day, we discussed the importance of significant figures in science. We started today by reviewing the definition and how to determine when a value is significant or not. We then covered two new rules: how many significant figures is our answer allowed to have when we 1) Add or […]

After briefly discussing the information we learned Friday regarding scientific notation (this will be on a quiz on Thursday!) we then began working with an entirely new idea: Significant Figures. Whenever scientists are conveying measurements or other quantities, they want to be sure they are reporting the appropriate level of certainty in their […]

Today’s objectives included defining “scientific notation”, analyzing the importance and usefulness of this system, and learning the rules to convert large and small numbers into and out of scientific notation.  We started the class by taking some guided notes on the properties of Scientific Notation.  To see all of today’s slides, download the Scientific Notation […]

Today students completed their first test of the semester. The test covered the first half of our experimental design unit: the scientific method, observations versus inferences, the metric system, conversions, graphing, and variables.
Unfortunately, I’m not swift enough to grade 145 of these tests overnight, thus the grades will not show up on PowerSchool […]

Today was all about test preparation. With this being the first test of the new year, we have taken a conservative approach to the study by walking through all of the steps for proper prepration. We started today’s class by passing back some graded papers and labs. We then organized these resources […]

We concluded our work with the metric system today by tying up several loose ends. We first defined two terms that will apply to much of our experimental unit: quantitative and qualitative. Remember the “N” reminds us of numbers, the “L” of letters. We then examined 3 significant reasons why the […]

Today’s continuation of science graphing techniques focused on extrapolating data from a graph. We began by discussing how to draw a conclusion from a graph. We then moved on to the meaning of extrapolate. From Merriam-Webster:
“the process of constructing new data points outside a discrete set of known data points.”
This process focuses […]

Students started today’s class by learning how to best approach complex derived quantity problems with the metric system. We walked through a couple of problems and showed why it is best to first convert all values into the necessary units and then plug those values into the formula. Students then turned in the […]

Today we corrected the Measurement Lab together in class.  The goal of correcting this lab together in class was to cement the knowledge gained in the lab.  Before students went on to tackle the post-lab, we wanted to ensure we were all on the same page with how to measure and record standard measurements in […]
