Row 1
What do solid particles look like? Draw an example on your white board.
Particles that are arranged close together and organized.
What do liquid particles look like? Draw an example on your white board.
Liquid particles are more spaced out because their particles have weaker attractions to one another - allowing them to flow.
What do gas particles look like? Draw an example on your white board.
Gas particles are usually spaced apart, they have the most energy, but the particles have the weakest attraction to one another so they can keep spreading out.
Name all 4 states of matter.
give an example of a measurement of mass
2g, 6kg, 98mg
Write an example of qualitative data
The sky is blue today
It is very cold out
The dog is light gray in color
What is an example of quantitative data?
The table length was 3.5m
The chair was 65.5cm
The sample weighed 250.0g
Give an example of a solid, a liquid, and a gas.
solid - car, chair, floor, ball
liquid - water, vinegar, soda
gas - carbon dioxide, water vapor, helium, oxygen, propane
give an example of matter and non-matter.
matter: tree, table, pencil, cell phone, car
non-matter: time, sound, an idea, sunlight
what is the dependent variable in this prompt?
if a student studies an extra 15 minutes a day, their grade will go up and improve over time
dependent variable is the Data we are collecting
dependent variable: how much the student's grade goes up
what is the metric unit for temperature?
Kelvin
Matter is anything that has....
mass and takes up space (volume)
explain how the particles in the oobleck (cornstarch and water) allow it to behave the way it does (as a non-Newtonian fluid)
the viscosity of the oobleck can change when under force (the particles separating and then coming together again when force is added, creating a "shield" of cornstarch particles)
what is the independent variable in this prompt?
if you water garden A more than garden B, more vegetables will grow as a result
independent variable: the thing we are changing in the experiment, the amount of water is what's changing
What was the term used to describe what oobleck is? (hint: think of newton's viscosity law)
oobleck is a non-Newtonian fluid
Convert 350mL to L
conversion factor: 1L = 1,000mL
show your work on the white board! Include your units!
0.35L
what are all the steps to the scientific method?
observation
hypothesis
experiment
collect / analyze data
conclusion / results
kinetic molecular theory states that....
all particles, even solids, are in constant random motion
Convert 9.25cm to m
use the conversion factor 1m = 100cm
(use your whiteboard)
