SCIENCE HW

1.      What are the two parts of digestion?

The Stomach and Small Intestine.

2.      How do those two parts differ?

The intestine is a lot weaker than the stomach. If you small intestine starts bleeding, there is not an easy way to stop it. The stomach can store things and all-like-a-that.

3. People who have lost most of their teeth may have trouble chewing their food. How does this affect their digestive process?

It may mean that they don’t get enough food and may get choked easier. It also means that the pieces of food may go down longer which makes things bigger and harder to store.

3.      What is the pH in your mouth? Stomach? Small intestine?

The normal is about 7 for your mouth. The stomach is about 2.0 which means it’s a pretty strong acid. The small intestine is about 8.

4.      Why are pH variations in different parts of the digestive system important to the process of digestion?

They vary because of the things that those 3 parts are used for in your digestive system.

Science HW

1.      What are the characteristics of solutions, colloids, and suspensions?

An example of a solution is water. Colloids aren’t affected by gravity. Suspensions can be filtered.

2. What happens to the particles of a solute when a solution forms?

The particles of the solute leave.

3.      How do solutes affect the freezing point and boiling point of a solvent?

The Substance will either rise or decline the boiling point or freezing point of a solvent.

4. Suppose you mix food coloring in water to make it blue. Have you made a solution or solution or a suspension? Explain.

You would make it a solution because the food coloring just mixes it but doesn’t change the whole particle.

5. What effects do solutes have on a solvent’s freezing and boiling points?

It raising or going down.

Science HW OBJECTIVE #2

1.       Concentration is when you need to know the ratio of the solvent to the solute.


2. Solubility is useful in find things because of common matter.  

3. Three factors: temperature pressure, and polarity.

4. Breaks the bonds.

5.The definition of Solubility is  the quality or property of being soluble; relative capability of being dissolved. This means that it would dissolve easily.

Homework #6

1. If volume goes up, so does pressure.

2. They move more faster.

Science HW #5

1. When Volume Goes Up, Pressure Goes Down.

2. For example when you go up from Asheville to Spartanburg every morning, your ears pop because you are on a higher elevation than Spartanburg. So, if you put a balloon in a car in Spartanburg, and drove to Asheville, more air would go into it.

3. Pressure x Volume = Constant

4. How you breath is why doctor's study this.

5. When Volume Goes Up, Pressure Goes Down. They depend on the formula. When they go down to the bottom of the ocean for example, the lower they go, the more air they must use.

Science-Concentration.

For the past couple of days, Reed and I have been working with concentration. We got five cups and filled them with 140 mm of water. In one cup, we put one drop of food coloring. In the next cup we put two, and repeated. The following picture shows what I mean. In the picture, you notice that the coloring gets darker. It goes from diluted to concentration.

Dalton vs. Democritus

A lot changed from 430 BCE and 1800. In 1800, there were a lot mor things to make use of than in 430 BCE.

The Scentific Method is this:

Ask a Question


Do Background Research

Construct a Hypothesis

Test Your Hypothesis by Doing an Experiment

Analyze Your Data and Draw a Conclusion

Communicate Your Results
 
In Democritus's time, he probaly asked a question and then he would test it. He probaly didn't have the materials that Dalton would have had in the 1800's. Dalton probaly followed the Scentific Method pretty well since it was just about 200 years ago. Obviously, a lot has changed in about 2,000 years, but it all evolved around the same topic.

 

 

 

 

 

VS......

Niels Bohr

I think I will do Niels Bohr for my Science Project. He's a pretty cool guy. He won the Nobel Prize in 1922. He was born in Denmark and attended Copenhagen Univeristy. One of his biggest influences was Ernest Rutherford..He also had a pretty cool family. His son won a nobel prize in 1975, just 53 years from his fathers.

Wants to do someone from the Section of History. Who should I do???
