This video is about our mistakes and where we need to go and what we learned.
This video is about what we have done in this project so far.
Math:
1. I improved as a mathematician because I can solve harder problems and connect them to other problems.
2. I am better at mathematical thinking because I get more complicated concepts.
3. I understand problems more than before. I am quite precise in my answers, even to the third or fourth decimal. I need to improve on my modelling.
Science
1.I know many concepts now and can put them to use in life now.
2.
Sea Breeze:
Sea Breezes come because the sea is colder than the land since water takes a long time to heat up so it cools down the air. The land is warmer so it heats up the air and the air rises. The land is a low pressure zone because there is less pressure since the higher the air is, the less pressure there is. Meanwhile the ocean is a high pressure zone because the air is sinking, which means that is is coming closer to sea level, therefore creating higher pressure. The cold air from the sea blows into the land, which heats up the air and the air goes across to the sea. When the air is heated and floats up, that is called an updraft. When the air sinks, that is called a downdraft. That is how a sea breeze is formed.
Land Breeze:
Land Breezes are formed when the sea is warmer than the land at night since the sea, more or less, maintains a steady temperature. Since the sun is down, the lands temperature has dropped enormously. Since the sea is warmer than the land, the sea heats up the air and creates a low pressure zone because of the high warm air. Meanwhile, the land is cooling the air down and making it sink, creating a high pressure zone and a downdraft because of how low the air is to the ground. The high pressure ind blows to the warmer place where it gets heated up and rises again, just to be cooled down again. This is basically the reverse of the Sea Breeze. That is how a land breeze is formed.
1. The Coriolis Effect is where if you are on the southern hemisphere thing seem to be curving to the left and in the northern hemisphere things turn to the right.
2. Earth rotating.
3. Right
4. Left
5. They will end up to the west in the Northern Hemisphere to their intended point but for the southern hemisphere it will end up to the east.
Convection is the transfer of heat through warm air. This happens because the particles in the air keep passing on the heat from particle to particle.
Conduction is heat going through an object or a material. The heat gets passed on from electrons that have lost the force to a nucleus and are wandering around passing on the heat.
Radiation is waves of heat. You can feel it from a farther distance depending upon the source. If the source is the sun, then the waves travel hundreds of millions of miles in less than 10 minutes.
1. Metals are good Conductors of heat because they have many free electrons going around to make molecules vibrate more to create heat through friction and free electrons.
2. Hot water and air rises because when they get heated up, they become less dense and therefore go higher up into the atmosphere.
3. There are radiation waves or heat waves that travel from the campfire to me and transfer heat.
4. Conduction is connected with the states of matter because all states of matter conduct heat, even if its good or not.
Q1: Describe the physical properties of the substance that remains in the evaporating dish.
A1: The substance in the dish has these physical properties: white in colour, mushy, closer together, softer, warmer, and wetter.
Q2: Where is the water that was in the salt water solution?
A2: The water is now in the air, adding to the humidity of the room. The air has dissolved the water, forming a cloud.
Q3: What do you think the substance is that remained in the evaporating dish?
A3: I think the substance is fresh salt because it was burnt to a point where the bacteria would die. Some of the bacteria could have mixed with the water.
Q4: What could you do to identify the substance?
A4: I could test its density, solubility and mass. I could just test all physical properties.
Q5: Explain why scientists would classify cereal as a heterogeneous mixture.
A5: Cereal looks different from the top to bottom and is not evenly distributed throughout.There are different colours and sizes, which makes it look different.
Q6: After a minor traffic accident, the police noticed that a solution had spilled and run off
the roadway onto the shoulder of the road. Describe how you could recover a
sample of this solution from the dirt, rocks, and sand on the road’s shoulder.
A6: I could use tweezers to remove the rock from the mixture, then use a spoon to get the sand and dirt. You should then be left with some unabsorbed solution in the cup.
Q7: When a scientist mixed together a number of substances, light, heat, and gas were
produced. The scientist could not separate the new substance using physical
properties like solubility, density, or color. Did the scientist create a mixture, or did
she produce something else? Explain how the product she produced was alike and/or
different from the homogeneous and heterogeneous mixtures you have used.
A7: The scientist produced a compound or something else, but definitely not a mixture because a mixture can be easily separated, a solution is a bit harder, but this is much harder than a solution. This is like a homogeneous mixture I have used because light is bright and same colour from top to bottom, heat is invisible and so is gas.
1. Mr.Anderson described solubility as how easy it is for the solute to dissolve in a given solvent. If the solubility is low then it is hard for the solute to dissolve but if the solubility is high it is easy.
2. Talc is insoluble because it cannot mix with water no matter how much you stir. Even if you stir a really small amount, it won’t dissolve.
3. Increasing the temperature of the solvent will increase the solubility of a solute because it will allow more of the solute to go in and dissolve.
4. There is less oxygen near the equator than at a higher latitude because colder water allows more air to dissolve than warmer water.
5. The fish keep dying because of the warm water. The warm water cannot dissolve as much oxygen as the previous cold water. This is why the fish die.
Here is my scrapbook so far for our Properties of Matter Unit.
