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?
They are aligned very closely and in an
arranged order. They do not move freely like they did in the liquid and gaseous
states. The hydrogen molecules are
attracted to the oxygen molecules.
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.
Oxygen becomes a
liquid at 71K and .35 ATM
5. List and
describe at least two Science Standards that this activity addresses.
C.4.2 Use the science content being learned
to ask questions, plan investigations, make observations, make predictions, and
offer explanations.
C.4.6 Communicate the
results of their investigations in ways their audiences will understand by
using charts, graphs, drawings, written descriptions, and various other means,
to display their answers.
