Students worked 3 practice problems on Converting in SI from Tera- to pico- on the board.  Then, students completed the SI Conversions WS (45 pts) in class.

Students wrote the SI prefixes, their numbers and their symbols from tera- to pico-.  Then, we practiced writing SI conversion factors before they began the SI Conversion Factors WS (34 pts).

Students took the Scientific Notation Test (20 pts) and began the prefixes of SI and their conversion factors.

Students completed a scientific notation WS after reviewing the rules on writing numbers in scientific notation and changing numbers to/from scientific notation.(48 pts)  They will have a Scientific Notation Test tomorrow.  We began notes on Conversion Factors in SI and SI prefixes after the WS.

10th grade students took the Aspire Test in class today.  11th graders received work from p. 100 on Conversions in SI today.

We reviewed how to Add and Subtract numbers in scientific notation w/their calculators first.  Then we copied the notes on how to  multiply and divide numbers in scientific notation. Soon after, we worked some sample problems from the text on dividing and multiplying numbers in Scientific Notation from their textbook.  Then, students completed the worksheet on +, -, /, and x numbers in Scientific Notation (48 pt)

Students were allowed to copy the notes on Temperature and compare the three temperature scales.  We also reviewed how to convert temperature from Kelvin to Celsius and vice versa. We also compared temperature and heat.  Finally we discussed how to add, subtract numbers in scientific notation.

9-20 (Wednesday)

We had a short poptest on scientific notation (10 pts).  Then, we reviewed the correct answers and completed the Scientific Notation WS ( 50 pts) in class.

9-19 (Tuesday)

Students were taught the 5 steps to writing regular numbers in scientific notation.  We learned the parts to scientific notation worked several problems, and were assigned the practice problems from p. R102, #54 (18 pts).  We also learned how to change scientific notation into a regular number.

9-18 (Monday)

The teacher was at a workshop, so students copied the rules for scientific notation from a worksheet and worked problems from their textbook on how to change regular numbers to scientific notation.  They also were to work problems dealing w/numbers in scientific notation (add, subtract, multiply and divide). All work was turned in at the end of the period.

Students completed the Density WPWS (40 pts) and began to review the steps to writing numbers in scientific Notation.  We continued the notes from the PowerPoint on Density, temperature scales and began scientific notation.

9-13-17 (Wednesday)

We took notes from the "Data Analysis" PowerPoint on derived units and Density.  We learned how to calculate density as well as the difference in an object with high and low density.  4th period was given the Density WPWS (40pts) for homework.
