1(I had to fix a lot of my answers) 2 (I had to fix some of my answers) 3 (I had to fix 1 or 2 answers)

1. What topic do you need the most help with?

2. What is one question you want answered?

TASK #2: Matter, States of Matter, and the Changes of Matter

Go to http://www.chem4kids.com/files/matter_states.html and answer the questions below by using this website. REMEMBER TO USE THE TABS ON THE SIDE ALSO. QUESTIONS ARE MIXED UP!

1. Define Matter:

2. What are the five states of matter? Which three are most common?

3. ______hold huge amounts of energy, and their molecules are spread out as much as possible.

4. Rust is an example of a ______change.

5. Breaking chemical bonds (for example breaking the bonds in water) is an example of a ______change.

6. What is another word for gas?______

7. ______is a special molecule. It has more ______in between its molecules when frozen, therefore it is less dense in its ______state than in its liquid state.

8. Melting a sugar cube is a ______change because the bonds in the sugar are not being altered…the substance is still sugar!

9. Draw particle visualizations of the three states of matter below.

Solid Liquid Gas

10. When you reach ______point, you have enough energy to turn from a liquid into a gas.

11. ______are a lot like gases, but the atoms are different because they are made up of free electrons and ions of the element.

12. The atoms inside a ______are not allowed to move around too much.

13. What are these changes in state called? Fill in the following chart. Also, write in the third column whether the particles are gaining or losing energy during these phase changes. (HINT: Think about if the particles end up with more or less energy after the phase change.)

Particles

gaining or

Name of State Change losing energy?

Solid to Liquid / Fusion (or melting) / Gaining
Liquid to gas
Gas to liquid / Losing
Liquid to solid
Solid to gas
Gas to solid

14. a. Label the following diagram (on each arrow) with the proper change of state (Use all of the changes of state from the chart above in the second column.)

b. When matter cools, energy is released from the particles into their surroundings. When matter warms, particles are absorbing heat from the surroundings. Label the arrows below: label one with the phrase, “Absorbing Energy” and the other with “Releasing Energy.”

TASK #3: Matter

Go to http://www.factmonster.com/ce6/sci/A0832242.html to answer the questions below. Use titles under “Sections in this Article” to find the answers. They are all mixed up too!

1. Name four properties of matter with their definitions. (You may need to research these definitions):

2. The ______is considered the basic unit of any element.

3. Describe the difference between an element and a compound. Give an example of each. You may have to do a little research.

4. In a ______change, such as a change of state (i.e. from a solid to a liquid), the substance as a whole changes, but it’s underlying structure remains the same.

TASK #4: Describing The Particle Motion of States of Matter

Have fun at this site watching the substance change states.

http://www.harcourtschool.com/activity/states_of_matter/index.html

1. Observe the gas particles in the magnifier. Describe the motion of gas particles in your own words.

2. Observe the liquid particles in the magnifier. Describe the motion of liquid particles in your own words.

3. Observe the solid in the magnifier. Describe the motion of solid particles in your own words.

4. Which state of matter has the most kinetic energy? Which state of matter has only vibrational energy?

TASK #5: Observations about Phase Changes

Melting/Heating Experiment—You can start it from the beginning as many times as necessary to help you see the change in temperature. http://harcourtschool.com/activity/hotplate/index.html

Once on this site, select the pink or green material. (Circle which one you selected.)

1. What was the melting point? ______2. What was the boiling point? ______

2. Sketch the graph that was created. Label the areas on your sketch where it melted and where it boiled.

3. What did you observe happening to the temperature when the substance was changing state?

4. What happened to the temperature once the entire sample melted? Boiled?

TASK #6: Describing States of Matter

Fill in the chart below using this site as a reference. http://www.chem.purdue.edu/gchelp/atoms/states.html
