Activity 5: States of Matter and Intermolecular Forces


1. Convert 0°F, 32°F, 70°F, and 212°F to Kelvin
  • 0°F= 255.4 K
  •  32°F = 273.15 K
  • 70°F= 294.26 K
  • 212°F= 373.15 K
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 on this blog.
 


 
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 0K. Describe how the water molecules are aligned and attracted to each other. Which atoms attract to which other molecules?
The water molecules are in line with the hydrogen atoms and then touch the oxygen atoms. The water molecules remain together and do not move.
 
4. Switch 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 temperature, pressure, and state of matter. Play with the simulation to notice changes, notice that when you push down the pressure can you go way up and explode the box. On your blog, report a temperature and pressure required to make a oxygen a liquid. This is sometimes how the oxygen exists in pressurized oxygen tanks, perhaps like the ones you may use to go driving.
A possible temperature and pressure that could make oxygen a liquid is a pressure around 3 ATM and a temperature of 113 K.
 
5. List and describe at least two Science Standards that this activity addresses
  • Group and/or classify objects and substances based on their properties.  (D.4.2)
This activity addresses the standard through having students move different elements to different states of matter including solid, liquid, and gas. Then students must be able to classify what these substances are.
  • Be introduced to the three states of matter: solid, liquid, and gas.  (D.4.3)
This whole activity is completely based on the different states of matter including solid, liquid, and gases. It is an excellent example of how to introduce students to the different states of matter.

    Nice job aligning Science Standards to the activities, Kelsey. I liked this activity and felt that it was a great way for students to investigate and learn about the different states of matter. Simulations such as these are a great way for students to understand the components (molecules and atoms) that are present in solids, liquids, and gases even though they can't see them in real life.

    Great job on this post! I really like how you typed your answers on your worksheet because it made it really easy for me to read it and compare it with my own responses. Also, I really like how you wrote why you thought each activity went along with the two standards you picked. It makes it easy to see what part of the activity fit, specifically, with the standard. Your whole post was really organized and easy to follow.

    I really like the way you got those pictures from the activity to your worksheet. It looks very clean and is easy to read. I also like your explanations for your standards. The reasoning aligned with mine and fit the standard well. Nice work!

    Great job on the worksheet, your pictures look awesome! They really help give a visual representation of what state of matter is being observed and how the internal interactions work. Having the pictures on there is a benefit for not only me but students as well.
