9/7 Warm-Up:
What grade do you think you will get on today's quiz and why?
I think I'm going to get at least a B because I've studied a lot and I've been
doing my vocab.
9/10 Warm-up:
A scientific model can take the form of a physical object or a concept. List one example below of each type of model.
Physical: A physical design like the interior of a plane
Concept: Can show ideas like modeling a comet as a giant ice ball
How does each one resemble what is supposed to model?
Physical: Shows what the plane looks like inside, dimensions, where seats are, components, etc.
--> Shows how it looks
Concept: If something is supported when tested, the concept of it is kept. If not, it is changed.
Shows how it works
9/11 Warm-Up:
If plants that get more sunlight make more food, then plants that get the most
sunlight will grow the tallest.
Table:
Plant | Hours | Highest |
1 | 3 | 52 |
2 | 6 | 73 |
3 | 9 | 120 |
After testing plants in different amounts of time, I learned that the more
sunlight causes the plant to grow higher. This can be proved because plant 1
which had 3 hours of sunlight only grew 52cm, while plant 2 which had 3 hours
gre 73cm. Above all, however, plant 3 wins with its 9 hours of sunlight and grew
to 120cm.
Possible Mistakes:
Time
Didn't check forecast
Confuse Plants
What I would do next time:
Check hourly forecast
9/12 Warm-Up:
Suppose you perform an experiment and your resulting data does not support your
hypothesis. What would you do?
Revise hypothesis, then test again

1.) Type of Plane
2.) Distance
3.) Everything else (meter stick, the floor, room, stood)
9/14 Warm-Up
Take out of scientific notation
3.78x10^5 = 378000
4.3x10^-3 = 0.0043
Put into scientific notation
0.00308 = 3.08x10^-3
578,600 = 5.786x10^5
9/17 Warm-Up
How many pops do I drink in a week? AHAHAHAHAHA! A lot. H*ll I don't even know.
I'd say probably around 10.
As for how many hours of TV do I drink in a week? Not much, really. I'd say 6 -
a little under an hour a day - at the most.
See 9/17 Warm-Up Table for Table, see Graph.png for graph
Ind: Students ---
Dep: Hours of TV |
9/18 Warm-Up
Create a line graph showing how the hours of tv watched per week changes based
on the number of pops drank per week
(pop/week on the x-axis and hours of tv/week on y-axis)

9/24 Warm-Up
For my test tomorrow, I think I will get an A(-/+) because I am very confident
in what we have been doing lately. I am going to study my notes in this database
tonight to prepare for tomorrow's test.
9/27 Warm-Up
What are 5 different mixtures you can think of? What makes these things a
mixture?
Lemonade, vinegar, salt water, milk, coke
Reason:
These are mixtures because its a mixture of 2 or more things
10/1 Warm-Up:
Does everyone in your group know what you are doing in your activity today? Do
you have a procedure and a data table ready to go?
yes yes and yes
10/2 Warm-Up:
What are the properties you can use to identify a solution, a suspension, and a
coloid?
If the light passes through, it is a solution
If it sort of passes through, but gets scattered, it is a coloid
If it does not pass through, it is a suspension
10/3 Warm-Up
In a mixture, what is considered the solvent and what is the solute?
Solvent - the initial item (eg. water)
Solute - the item mixed (dissolved) into the initial item (eg. salt)
What are 6 physical properties of matter?
Look, type of mixture, smell, light passing through, viscosity, melting point
10/4 Warm-Up
Explain why boiling water is a Physical Change. What are 2 other examples of
physical changes you can think of that are not water examples?
Boiling water is a physical change because it turns water into a gas (water
vapor).
Two other physical changes is melting a rock and liquidizing Nitrogen
See “Filtration.png” for picture
10/5 Warm-Up
What is the Tyndall effect?
The Tyndall effect is what happens when you shine a light into a solution and
the light scatters in all directions.
What kind of mixtures show the Tyndall effect?
Colloids show this effect
10/11 Warm-Up
=============
Please give an example of a physical change and a chemical change. How do you
know which is which?
A chemical reaction is when the composition of a material changes, such as iron
rusting.
A physical reaction is when the composition of a material stays the same, such
as ripping a paper in half.
You can tell if it is a chemical change if there is a color change, production
of gas, and/or there is a formation of a precipitate. However, this can't always
tell accurately. To be completely sure, you must see if there is something
completely different in the end.

What are you going to do tonight to make sure you are ready for your quiz
tomorrow?
===================================================================
I will read over my notes and practice them for about 2 hours.
10/12 Warm-Up:
Check your grade – is it what you want it to be?
Yes. B and up is fine with me.
I will study for the test by studying over the weekend to help me with the test
on Tuesday.
10/15 Warm-Up:
If you found an unknown powder in the lab, how could you test it to figure out
what it is?
Test solubility (seeing if it dissolves in water), heat it up to melting
point/boiling point, color, how big the particles are, see what it feels like,
density, etc.
First I would note its color. Then I’d measure the mass and volume to get the
density. I’d also then test its solubility. Last, I’d find its melting point and
its boiling point.
10/16 Warm-Up:
What grade are you going to get today and why?
I think I’m going to get at least a B because I’ve studied a lot during the
weekend. I will at the least know the vocab fairly well.
