Activity 5:
1. Convert 0°F, 32°F, 70°F, and 212°F to Kelvin
0°F = 255.372
Kelvin
32°F = 273.15
Kelvin
70°F = 294.261
Kevin
212°F = 373.15 Kelvin
2. Complete the Teaching Idea: States of Matter Simulation Lab by
Kelly Vaughan. Complete the lab worksheet as if you were a student, and then
post this on your blog. You can scan it or just take a picture of it.
3. In the States of Matter simulation, choose the Solid, Liquid, and
Gas Tab at the top of the screen. Choose the water molecule and cool the water
to 0 K. Describe how the water molecules are aligned and attracted to each
other. Which atoms are attracted to which other atoms?
When the
temperature is lowered to 0 K the water molecules are all tightly packed and
all touching. They are very attracted to each other and none of the molecules
are moving. The white atoms are attracted to the other white atoms and are
touching.
4. Switch to the Phase Changes Tab on the States of Matter simulation.
Notice how on the bottom right there is a small red dot that indicates where
the system is at as far as temperature, pressure and state of matter. Play with
the simulation to notice changes, notice that when you push down the pressure
can go way up and explode the box. On your blog, report a temperature and pressure required to make oxygen a liquid.
This is sometimes how the oxygen exists in pressurized oxygen tanks, perhaps
like ones you may use to go diving.
Temperature= 119 K
Pressure= 1.7 ATM
5. List and describe at least two Science Standards that this activity
addresses.
- Science Standard A: Science Connections Performance Standards-Grade
8:
- A.8.1 Develop their understanding of science themes by using the
themes to frame questions about science-related issues and problems
- A.8.5
Show how models and explanations, based on systems, were changed as new
evidence accumulated (the effects of constancy, evolution, change, and
measurement should all be part of these explanations)
- Science Standard D: Physical Science Performance Standards- Grade 8
- D.8.1
Observe, describe, and measure physical and chemical properties of
elements and other substances to identify and group them according to properties
such as density, melting points, boiling points, conductivity, magnetic
attraction, solubility, and reactions to common physical and chemical
tests
- D.8.2 Use
the major ideas of atomic theory and molecular theory to describe
physical and chemical interactions among substances, including solids,
liquids, and gases
I used one of the same science standards you did. I used D.8.2 Use the major ideas of atomic theory and molecular theory to describe physical and chemical interactions among substances, including solids, liquids, and gases. I used this because this entire activity was based on the substances solid, liquid, and gas. It showed what the substances looked like in different states which is where the interactions come into play.
ReplyDeleteYour answers are very full and complete. Your estimations of the states of matter at the beginning of the worksheet are very accurate. Your pictures are very neat and easy to visualize. Great post!
