Bending Glass

This week we watch our classmates bend glass. I thought it was very cool and interesting. I watched people file the glass tube first and then they break it inward so the glasses won't fly everywhere. then they hold the glass piece up to the fire and heat it up until it was very malleable. After a while, it was very bendable and I watched them bend the glass into very interesting shapes.
But first of all we must remember Safety First!!!

I Propose We make a golden rod paper that looks like it is bleeding

Goldenrod paper looks like it is bleeding when exposed to basic solutions.
Here's a video: enjoy!

Materials:

• Goldenrod paper
• Cotton balls
• Ammonia-water solution (household ammonia from the grocery store)
• Safety glasses
• Candle

Procedures:

1. Place a piece of goldenrod paper on the table. Make sure that table is clean and the work surface is dry.
2. Place a drop of water on one of the corners of the paper. Does anything happen?
3. Fill a jar with a small amount of ammonia water. Dip a cotton ball in the ammonia water and wipe it across the top portion of the goldenrod paper. Save the bottom half of the paper for step 5. Does anything happen?
4. As you continue to wipe designs on the goldenrod paper, notice that the paper does not stay red forever. What is causing the paper to change back to yellow?
5. Use the old piece of wax candle to write a secret message across the bottom half of the paper.
6. Wipe the cotton ball with ammonia water across the secret message to see what develops.

Safety Precautions:
1. If you get the basic liquid on your hands don't touch face or eyes.
2. Watch out for he sharp corners of the paper so you won't get a paper cut.

Scientific Principles:
1. Certain brands of goldenrod paper contain a special dye that turns bright red in solutions that are basic like ammonia water or washing soda.
2. The paper turns back yellow with an acid like vinegar or lemon juice.

Star testing week

This week was very hectic because the school schedule was messed up and i forgot what class was gonna come next. I think i did very well on the star testing because i thought it was pretty easy. We also get to go on a class field trip on April 29 at Mills Creek Canyon. I hope we get a good experience from this trip and i can't wait to go and learn from this lab we're gonna do.
