Feb 2, 2016

Dear Families,

Today was a little unique, between no running water and porta potties, myself being very sick over the weekend, our field trip to the symphony and a guest art teacher... things were unusual to say the least.  We did no have a chance to do our logs today.

We are not having vocab work this week.  We are finishing up some projects this week.
For homework, students should be reading (AR goal period ends March 2nd -Wednesday).  Also it would be wise for students to work on finishing their drafts of their persuasive work.  We will be working on finishing our final drafts in class this week.


Thank you,
Ms.  Sara

15.  gravity- The force of attraction between two objects (such as the force between you and the Earth).

16.  lift- The force that keeps an airplane up due to the flow of air over and under the wings.

17.  mach- A number that compares an airplane’s speed to the speed of sound 750 mph. (At Mach 2, a plane goes twice the speed of sound).

18.  supersonic- A term that indicates motion faster than the speed of sound (more than Mach 1 but less than Mach 5).

19.  astronaut- A person who trains to fly into space.

20.  engineer- A person trained to design, construct, and operate mechanical or electrical instruments

21.  ration- A fixed amount of food or water when the supply is limited.

23.  space station- A manned structure that orbits the Earth and is used for a variety of purposes, especially research

24.  space probe- An unmanned spacecraft that explores the solar system and sends data back to Earth

25.  altitude- The height above sea level.

26.  lunar- A term referring to the moon.

27.  Infrared - A type of light that can’t be seen by humans but that instruments can use to measure the heat differences between objects.

science fair reminders

                                Mar Vista Science Fair 2016

2/3/2016   science fair project due (in Mar Vista MPR)  and  6-7 parent night
*we will be presenting our projects in class on 2/5
2/12/16   registration for the county science fair closes
3/12/16  county science fair

About your board and journal:

Journal:   Should  really be a record of your experiment planning, process, thinking, observations and practice for presentation board.  No white out or erasing, just cross out with a single line.

entries should include:

-choosing project/research done

-gathering supplies

- setting up the experiment ( intro, hypothesis, procedure)

-  what happened during the experiment (observations/data/results/thoughts and ideas/problems that occur changes that need to be made etc)  (anything and everything…the more the better)

-if you had to watch your experiment over a time period you should record your data/observations

- why did you get those results?  what was learned (conclusion)

Science Board

Introduction What is your experiment’s purpose? What is your question your are trying to answer? What are you trying to solve/figure out? Hypothesis What do you think will happen? Methods/Procedure: What are the steps of your experiment?

CATCHY TITLE AND SCIENTIST NAMES Visuals Photos, graphs etc. Data data tables, charts and/or observations Results What were the results of your experiment? What happened? What did you find out?

Discussion/Conclusion Was your hypothesis supported or not? Analyze and interpret your results?  Why do you think you got the results that you did? What do results mean? What were sources of error or problems? What are your next steps? Why does this matter? References Any resources used or research done (websites, books, magazines etc.) Acknowledgments people to thank or those whole helped you in some way.

* we will be presenting our boards in class on (do not take them home until after you present them in class) 

Presentations will be short (1-3 min)- where you describe your experiment- what you did and what you were trying to figure out?  What the results were?  Why it is important/what you learned?

*You only need to do a science report if you go to the county science fair.
