1. There are four sections of the orchestra. Which section does the guitar belong to?
- String

2. List the other sections of the orchestra.
- Strings, Brass, Woodwind, Percussion

3. For each sections list 10 instruments for each section. 
Strings: Guitar, Violin, Harp, Viola, Cello, Bass
Woodwind: Flute, Clarinet, Oboe, Piccolo, Bassoon, Contra Bass Clarinet, Saxophone, Recorder
Percussion: Piano, Triangle, Maracas, Drum, Cymbals, Tambourines, Drum, Xylophone, Chimes, Gong
Brass: Trumpet, French Horn, Tuba, Trombone, Cornet, Fluegel Horn, Sousaphone

Investigating State Changes

Aim: To observe water as it changes state from a solid to liquid and then to a gas

Method: 
1. Collect enough ice so that your beaker is half full and place the thermometer into it while you set up the rest of the equipment.
2. Set up the retort stand and clamp alongside the tripod and gauze mat.
3. Place the beaker of ice on the gauze mat and gently clamp the thermometer so that it is held upright and the scale is easy to see. The bottom of your thermometer should be low enough to still be covered by water when the ice melts, but not touching the bottom of the beaker.
4. Record the initial temperature of the ice in the table below.
5. Light the bunsen burner and start timing with the stopwatch.
6. Measure and record the temperature every minute.
7. Continue measuring and recording the temperature until the water has been boiling for 2-3 minutes. 

Results: Each minute we recorded how long the temp would go. It got higher and when we turned it off it got lower

Mathematical Concepts

1. Light travels at c=3x108 meters per second. How long would it take light to travel from the Sun to Earth? 
8 Minutes 20 seconds

2. How long would it take for light to travel Neptune? 
14998.0 seconds 4.1 hours

1. Excellence
2. Using both hands at the same time.
3. Focus on the tunes and using both hands

CHROMATOGRAPHY

Separating a mixtures using Chromatography

Aim: To separate the different pigments in inks or dyes using paper chromatography

Method: 

1. Cut a piece of filtered paper long enough to reach the bottom of your test tube.

2. Rule a line in pencil 2 cm from bottom of paper

3. Fill test tube with 1 cm of chromatography solution (water)

4. Place a dot of ink above the ruled line.

5. Fold over test tube and place in solution.

6. Wait and observe

7. Repeat with 2 other colors 

Results: 

Discussion: I used cold colors for this experiment. The water soaked the ink. The water attaches its self from the paper which rises the ink up and it make a ombre color. 

Evaporation

Aim: To separate a solute from a solvent in a solution using evaporation.

Equipment: Copper sulfate solution, 250 ml beaker, heatproof mat, an evaporating basin, Bunsen burner, tripod, gauze mat.

Method: 

1. Set up the bunsen burner, tripod and gauze mat. Don't place the Bunsen burner under the tripod.

2. Add approximately 50 ml of hot water to your beaker and place it on top of the tripod, on the gauze mat. 

3. Add enough copper sulfate solution to quarter fill the evaporating basin.

4. Carefully place the evaporating basin on top of the beaker.

5. Light your bunsen burner. Open the air hole and gently push the Bunsen burner under the tripod.

6. Heat the solution until most of the solvent has been evaporated and crystals of solute are forming.

7. Turn off your bunsen burner.

Results: 

Discussion: We started with the copper sulfate solution and let it sit to boil. The gas evaporated in the water. There was residue around the basin. We left it to evaporate by the window. Once we came back, we were left with blue shiny crystals.

Separating A Mixture Using Distillation

Aim: To separate a solute from a solvent in a solution using distillation.

Equipment: Blue food coloring, conical flask, heatproof mat, a delivery tube, and bung, Bunsen burner, tripod, gauze mat, retort stand, boss head, and clamp, boiling tube

Method: 
1. Set up the equipment as shown in the diagram.
2. Add approximately 50 ml of water and a few drops of food coloring to your conical flask.
3. Light your bunsen burner. Open the air hole and gently push the bunsen burner under the tripod.
4. Heat the solution until most of the solvent has been evaporated. Turn off your bunsen burner.

Results: We are using coke to condense it.

Discussion: The solution gets boiled n heated which creates gas. The gas evaporates into steam and flows through the delivery tube then condensing back into a solvent. Whats left behind is tartar which is a solute
