- 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?
- At 0 K, the water molecules are very attracted to each other and are all touching. None of them are moving and the white atoms are attracted to the other white atoms.
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: 123k Pressure: 1.3 ATM
5. List and describe at least two Science Standards that this activity addresses.
- C.8.4 Use inferences to help decide possible results of their investigations, use observations to check their inferences
- C.8.9 Evaluate, explain, and defend the validity of questions, hypotheses, and conclusions to their investigations
- 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
- D.8.3 Understand how chemical interactions and behaviors lead to new substances with different properties
I like how you printed out the worksheet and filled it out. I think that is a example of how we all learn differently and must identify this with our future students. Like I prefer to type out worksheets. I respect that you use standard C.8.9 it is important in all areas of study to evaluate what we learn. This activity does that many times.
