What is this pink goo?



This is the filler in mcdonalds "chicken" nuggets.  This material needs to be soaked in ammonia to kill the billions of bacteria.  The substance also needs to be bleached white to look more like chicken meat.  Why eat something this processed?

Phase Change Diagrams

What is a phase diagram?

A phase diagram is a convenient way of representing the phases of a substance as a function of temperature and pressure. Below is the phase diagram for water.


Phase Diagram of Water


As seen above, one can determine from a phase diagram what state the water will be in at a certain temperature and pressure. For example, at 1 atm and 100º Celsius both liquid and solid water will exist.

**Note that a phase diagram describes conditions and events in a closed system where no material can escape into the surrondings and air is present


The phase diagram of water is very different that the phase diagrams of other substances. One unique thing about water is that the boundary line between the solid/liquid sections has a negative slope, meaning that the melting point of ice decreases as the external pressure increases. This occurs because the the density of ice is less than the density of water, which is not true for other substances. For example, below is the phase diagram for Carbon Dioxide.

C02 phase diagram

Note that unlike water the line between the liquid/solid sections has a positive slope unlike water.

Below is the phase diagram for carbon. By defintition a phase diagram shows the different states that a substance could be in, and the temperatures and pressures at which it occurs. Carbon is different from the previous two because it can exist in different states as a solid:

The common graphite:     graphite  
And the more expensive diamond: Diamond


The reason diamond is more expensive is because of its rarity, which is clearly evident in its phase diagram.

diamond



As shown in the phase diagram above it takes huge amounts of pressure and temperature to form a diamond. While diamond can be formed artificially, it is too expensive to compete with the natural stores of the stones found in various parts of the world.

5. Check your questions – Have you answered them in your research? Do you need to research further? Is the question important?
6. Draw a web diagram – Write Dr. Blumberg's name in the middle and facts or ideas that you want to write about in each circle. When you find more details about your facts and ideas draw smaller circles off of the bigger ones. This web will help you as you write your sentences.
7. Write your first draft – This is also called a rough draft, it doesn’t need to be perfect, it is just to help you get your ideas on paper and get your paragraphs moving in the right direction.
8. Revise your paper – Use the revising checklist to make sure you have a great paper coming along. Read your paper and ask other people to read your paper.
9. Write your final draft – Now that you have worked on your paper and gotten some help from others, make changes until it is just as you like it.
10. Proofread your paper – Use the proofreading checklist to make sure you have not made any spelling or grammatical errors. Correct these errors as you find them
11. Write the bibliography – Use the bibliography sample sheet to correctly write down the information for the sources that you used.
12. Find your photos – If you have not found a photo of Dr. Blumberg and his work yet, find one and print it out. Look at the photo sample page for ideas.
13. Create your cover page – Your cover page should have the title of your paper in the center and your name underneath it. Look at the sample cover page for ideas.

Happy Sequential Day

Yesterday Sequential Day was celebrated in Britain and many other countries where they abbreviate the date by having the day of the month followed by the month followed by the year (8/9/10) instead of the US version of the month followed by the day of the month followed by the year (9/8/10).

Sequential Day is celebrated at 12:34pm and 56.7 seconds on 8/9/10

The phenomenon is so rare that the last ‘pure’ sequence fell at 01:23 and 45 seconds on 6/7/89 and the next will take place at 01:23am on 4/5/67 - in 2067.

Where were you during Sequential Day at 12:34?

Science Lab Safety Contract

SCIENCE LAB SAFETY CONTRACT

Wow! It is so exciting that you would be able to perform a lot of "scientific investigations and experiments", but it can be dangerous if the proper precautions aren't followed. If a student chooses not to follow the rules below, you will not be allowed to participate in lab activities. You will do an alternative assignment, assigned by the teacher. To make sure that your laboratory experience is both exciting and safe, follow the general guidelines listed below:

1. Be respectful, follow your teacher's instructions, and don't take shortcuts.
2. Always get your teacher's permission before attempting any laboratory investigation.
3. Read the procedures carefully, paying attention to safety information and cautionary statements.
4. As a responsible citizen, be aware of the location of and the procedure for using the nearest fire alarms, fire-evacuation routes and any other safety equipment, such as fire blankets and eyewash fountains.
5. Never work alone in the laboratory.
6. Walk with care and keep your work area free from all unnecessary clutter. Keep backpacks and other belongings at a certain place designated by your teacher.
7. Dress appropriately on lab day, tie back long hair, remove dangling jewelry and wear closed-toed shoes or sandals in the laboratory. Wear an apron to protect your clothing from staining, burning, or corrosion if instructed by your teacher.
8. Certain products, like hair spray, are flammable and should not be worn while working near an open flame.
9. Wear approved safety goggles when working with or around chemicals, any mechanical device, or any type of flame or heating device. If any substance gets in your eyes or spills or your skin or clothes, rinse it immediately with water and have someone notify your teacher.
10. Wear protective gloves or oven mitts to avoid burns.
11. Be trustworthy and never touch, taste, smell or mix any chemicals unless your teacher instructs you do so.
12. Use knives and other sharp instruments with extreme care. Always cut an object after placing it on a suitable surface for cutting.
13. Handle plants and animals carefully and wash your hands afterwards. Always treat animals with care and respect.
14. While using electrical equipment, be careful about the wiring, hanging and damaged cords. Be sure your hands are dry and the electrical equipment is turned off before plugging it into the outlet. Turn off all equipment when you are finished using it.
15. Be a responsible and careful scientist by examining glassware to make sure that it is clean and is free of chips and cracks. Report damaged glassware to your teacher.
16. CLEANUP: Clean your work area before leaving! Follow your teacher's directions for washing, unplugging and putting away the equipment. Wash hands with soap and water after working in the laboratory.
17. Stay, work and talk to your own group. Don't leave your group and work area unless instructed by the teacher. Do not sit on counters or tables.

Student: I have read the science safety rules and agree to follow them.
