## Science Friday

We updated our moon journal and then worked in the moon phase simulation (see previous post for link).

We updated our moon journal and then worked in the moon phase simulation (see previous post for link).

Students started work with ACE review for the quiz. They will have class time on Tuesday, also, to work on the ACE problems and mathxl, if needed.

Due Wednesday before the quiz:

ACE chapter 2: 23-31 and 40

ACE chapter 1: 15-17, 27, 34-52

- I can solve for the volume of a sphere, cone and a cylinder (in pi form, without using calculators).
- I can write two equivalent expressions for a problem situation and show that they are equivalent.
- I can show that two expressions are or are NOT equivalent and justify my answer through algebra, tables and graphs.
- I can combine expressions to solve for problem situations (Profit, expense, income problems).
- I can factor out the greatest common monomial of expressions and use the factors to solve problem situations.

We continued our work with volume of spheres, cones and cylinders. Students completed unit 2.4 and ACE from Chapter 2, numbers 10-12 and the volume worksheet.

Due Friday: 2.4 and ACE and Weekly Review

Quiz on Wednesday, 2/21 and Mathxl unit 1 due 2/21.

We continued our exploration of the sun-earth-moon system and the phases of the moon. Students read information from the University of Nebraska-Lincoln Astronomy department. They then began an exploration of the lunar phases using the above simulator.

Students also need to continue work with the moon phase journal (daily). For cloudy days, students may use: Time and Date dot com moon information

We finished “If We Had No Moon” and handed in the notes. We then walked through the phases of the moon on our worksheet and looking at a lamp and the earth and the moon.

We then worked through the oreo cookie lab. Finally we launched the Moon Journal (students will do a little each day for the next 28 days) and then closed with relative sizes and distances of the earth, sun, moon system.

We reviewed our notes for volume of cylinders and cones and then added the notes for the volume of a sphere: 4/3 * pi* r^3 (or “4/3 pi r cubed”).

Students practiced by working through unit 2.3 and ACE problems 13-16 (Chapter 2) due Thursday.

WR due Friday

Quiz and mathxl due on 2/21.

Students viewed “If We Had No Moon” and took notes.

Students worked on unit 2.1 to combine expressions to solve a problem situation. They further practiced with Income, Expense, Profit equations (Profit=income-expenses).

Due Wednesday: 2.1 and ACE (chapter 2) 1-5 and 21, 22.

Due Friday: WR

Quiz and mathxl due 2/21

Today we finished our work with ellipses and elliptical orbits.

We finished the work on the elliptical orbit lab and handed it in.

Students read about orbits from sheets I printed out from this site:

Students were to be able to define and explain orbits in their own words when done reading.

We then re-looked at our notes about Kepler’s laws and made sense of Kepler’s laws of planetary motion in terms of the orbits.
