Hi parens and teachers, Just a friendly reminder that the science fair projects are due on 10/19
Keep the Good hard Work!
Dear parents and students,
FYI,
There will be a quiz on Wed Sep 30 on the following:
-Scientific notation
-Significant figures(identifying, adding,subtracting,multiplying, division,)
-Calculating mean, mode, median, range in a set of values
Good luck!
Mr Fuamenya
Dear Parents and students!
1. The NOS 1 -NOS 4 of your work books are due tomorrow 9/21
2. Science fair research project will be held due on Friday 9/25.
- Please review the following information as you prepare for complete the research piece.
- The students may present their project on a power point, or they may do the backboard, After the initial judging of the projects-by staff and peers, the students who will go on to the formal judging on October 27, must put their project on a backboard.
- Research paper, materials list, variables, and procedures are also due on the September 25th.These should be typed, 14 font, Times Roman Numeral, and double-spaced. Students need to proofread their work and use spell check.
- Please remember, if students hand in information printed off the internet as their research paper, a grade of zero will be given. The research paper must be in their own words. You need a minimum of three resources for your background research and google.com, yahoo.com or ask Jeeves cannot be used as a resource.
- ln addition, information from Wikipedia is not allowable,
ln order to get the full points, the items must be turned in on the due date.
Keep the good work Going!

Read the following sentences and circle the letter of the word that best fills each blank:
The 2 method is a process that scientists use to help them test new ideas. The first step in the process is defining the 3 . Next, information must be gathered using one or more of the five 4 .The scientist then makes an educated guess or a(n) 5 . This is tested by performing one or more activities called 6 . Observations are made and recorded. The recorded observations are known as 7 Afterward, the scientist comes to a 8 that either supports or does not support the hypothesis. When a hypothesis is tested many times and supported by data, it becomes known as 9 .

Qualitative Observations vs. Quantitative Observations Worksheet
All of the observations in this worksheet were qualitative; that is, you observed a quality about an object (it smelled good, it was green, etc.). Another type of observation is quantitative, meaning that it can be described or measured in concrete numerical terms.
- The following observations are quantitative: There are 30 students in my class. I weigh 98 pounds. I ate a pound of potatoes.
Determine which of the following statements are quantitative and which are qualitative.
|
_____1. The cup had a mass of 454 grams.
_____2. The temperature outside is 250o C.
_____3. It is warm outside.
_____4. The tree is 30 feet tall.
_____5. The building has 25 stories.
_____6. The building is taller than the tree.
_____7. The sidewalk is long.
_____8. The sidewalk is 100 meters long.
_____9. The race was over quickly.
_____10. The race was over in 10 minutes. |
