Mapping Project



Mapping Project



Introduction
It was a way how we study about vector mapping which we have to make a map for someone to walk follow the map that we make.I was very excited because I never have been making a map.I follow the Bew's map which was very good because they can make me confused the way that they made.We know the end point was Library.

Direction

Exploring color



Exploring color



Material

-  Flashlight
- Red filter
- Blue filter
-Green filter
-Yellow filter
-Purple filter

Procedure

Activity A:
1. look at the monitor
2. r+g, r+b, b+g
3.  work with another group—put a color paddle over flashlight, shine on white paper—so a red, a green, and a blue




Activity b
3.  view white paper through color paddles—record results
4.  view colored objects through color paddles
5.  if you have time, do activity b—color by subtraction--

- When putting red and blue paddles then, turn on the flashlight it will change color to be a violent color.On the other hand, we can see that when we use red and green colored paddles to mix it up color will become an orange colored.This lab experiment will take our get better score from this lesson because of when students do it for know everything they can get better in knowing things.We can know that when we add more color such as blue, red, and green paddles.These three color will change into white color.





Color by subtraction

Red + Blue = Violent or purple
It changes from red and blue that will add completely becomes violent.Moreover, if we put the flashlight on the white paper we can see clearly.The result is Magneta


Red + Green = Yellow
I put red and green paddles and then I turn on the flashlight to pass through them.It changes color to be a yellow color.The way that we can see more clearly is put the light on a white paper.The result is Cyan


Blue + Red = Green



I put red and blue paddles together and then these color will change color into green when we turn on the flashlight pass through it which we can see clearly when we turn off the light and put the flashlight on a white paper.The result is Green

Color by addition








When putting red and blue paddles then, turn on the flashlight it will change color to be a violent color.On the other hand, we can see that when we use red and green colored
paddles to mix it up color will become an orange colored.

Crystallization of Milk


Crystallization of Milk Report


Procedure

1. We have to prepare the material before doing the experiment
2. Put milk inside the zip lock bag
3. Put the ice in bucket and put ice on only one side
4. Then, put the zip lock bag on that side
5. Put the ice on top the zip lock bag and put salt on it
6. Push and pull the ice to the zip lock bag by test tube rack.Do this step until the milk freeze and put some toppings in the zip lock bag.
7. Take out ice cream to box and enjoy eating

Material

- Test tube rack
- Ice
- Salt
- Bucket
- Glass
- Spoon
- Zip lock bag
- Milk
-Topping

Result after the experiment

It uses a long time to make the milk to freeze like ice-cream which we use ice and put salt on the top of the ice which is the best way to keep a low temperature.The ice-cream tastes good when we put the topping on the top.This experiment we want to test crystallization of milk and know how milk is crystallization.

Question after the experiment

1)  why do we add salt to the ice?

Ans. It makes ice to freeze together and can keep the cooling more than in the past.Moreover, it will melt slower and make low temperature.

2)   why do we add the cookies and other things, only after the milk has frozen slightly

Ans. When we add the stuff inside ice cream, it will take a long time to freeze.

3)  what are two factors that affect the freezing you think?

Ans. Movement and temperature

4)  why do you need a bit of air in the bag?

Ans. We need air to have space to touch the ice or to make a milk move to contact the ice.

Stony lab


Stony Lab





  


Lab

Today's lab is very interesting for me because I never try this experiment before so I have to find the mass by old scales and then I put the stone in a beaker that already has 250 ml.Then I use a cylinder to get some water that is more than 250ml.Finally, I find the density.

7. Calculate the density of each of your mineral samples.How could you use the densities to identify the minerals?


I find the mass first because it is the easily way to find because it uses scales to find.Then I use the method that finds the volume by displacement.Finally, use the density to find it by density is equal to mass over volume. 


Key Concept Would density or color be more useful in identifying a particular mineral?Explain your answer.


Density is very useful in physic because when we have to find the particular mineral we have to use this because it is the easy way to find.Moreover, each mineral has different density and this is the method to classify each mineral.

Color is probably the easiest property to observe. Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a gold color, and so think it is gold. But it might actually be pyrite, or “fool's gold,” which is made of iron and sulfide. It contains no gold atoms.

Writing assignment



Technology from human is the Effect to Environment



Acid rain

     It makes a lot of things in the environment to be bad because acid rain means rain has pH below than seven so it will damage the tree.After it damages, the tree can't make a food for animals to eat because it doesn't have a chlorophyll to get sunlight and gas carbon dioxide to make food.Moreover, if it falls in the water or river.Fish at the river will die because at the river has pH less than seven so fish can't adapt their life in the river and die.

Image result for acid rain



Coal Pollution

Coal pollution is the cause of acid rain because it has sulfur dioxide, nitrogen oxide.particulate matter and heavy metals so that it can make lots of pollutions.For example, smog, acid rain, and toxins in the environment.If it has a lot, the earth has a greenhouse effect and some animals can't adapt and die.



Nuclear power

It will make a greenhouse gas in the world and lots of pollution too so you can't breath comfortable so you and animals will die if you stay outside all day.

Essay M1


           


 Essay M1

     This is the first year in Payara high school.I like this school because I can share my data with my friend and teacher.I think I like science because I like to try new things and make experiment so I like it.
     My highlight of this year is I will have competition in riding a horse because I think that in grade six, I prepare for the exam to the new school and I can't ride a horse or have some competition of riding horse.I think that is a year, I will manage my time for study and ride a horse.Moreover, I want to find a new thing about science because I think I want to be a veterinary doctor to help animals.In the next year, I will help my mother and my father to study hard and play football of my brother.I want to take care my brother because he will contract with his football team in Thailand(Bangkok Glass F.C.) so He will study hard and prepare for his football team every day.In M.2 I want to be an expert on Science.I will improve my speech and my report about science(Biology, Chemical)
