Revision for heating exam - READ THIS FIRST      posted 06-24-2012
Here is a test for you to see how well you understand some of the main points of this unit. Write your answers on a piece of paper and then check them to see what you need to study.

BTW this test will only help you if you do it as a test.

1. The freezing point of water is --- [1]
2. The boiling point of water is --- [1]
3. The change of state that happens when water reaches the boiling point is called --- [1]
4. What happens to water molecules when water is heated? [2] [There are 2 essential points to remember here.]
5. a. Heat is transferred in a fluid by the process of --- [1]
b. Warm water rises because .............. [1]
c. Heat can't be transferred in solid in this way because ........... [1]
6. A dog cools itself by letting its tongue hang out and panting.
a. Its body heat provides the --- energy to heat the water on its tongue. [1]
b. The particles with the most energy escape into the air. These particles are at the --- temperature. [1]
c. Therefore as the water ---, heat is transferred from the dog to the air, so the dog gets cooler. [1]
7. List the following in temperature order, starting with the coolest: the Sun (a yellow star), Rigel (a blue star), a white star, a red star. [1]
8. Thermal energy means the same thing as --- [1]
9. --- is a measure of the average kinetic energy of the particles of an object of any size. [1]
10. --- is the total amount of energy in an object of any size. [1]
11. a. There is a glass of water, and a sink full of water at the same temperature. Which one has the most thermal energy?
Choose the letter of the right answer. (A) the glass; (B) the sink; (C) They're both the same. [1]
b. Explain your answer to part a. [1]
12. Why does a metal ring expand when it gets hot? [2] [There are 2 points to mention here.]
13. a. A metal spoon has been left in a pan that's cooking on the burner. You will burn your hand if you touch it. Heat is transferred from the gas ring to your hand by the process of --- [1]
b. In particle terms, how does this transfer work? [1]



Exam revision material - SECOND page      posted 06-23-2012
The answers are shown /like this/. [Comments in brackets.]

1. The freezing point of water is /0 degrees C/ [Did you include the units? I can't make the degree sign on this webpage!] [1]
2. The boiling point of water is /100 degrees C/ [1]
3. The change of state that happens when water reaches the boiling point is called /evaporation/. [1]
4. What happens to water molecules when water is heated? /They have more energy AND so they move apart./[2]
5. a. Heat is transferred in a fluid by the process of /convection/. [1]
b. Warm water rises because [it's less dense than cold water/. [1]
c. Heat can't be transferred in solid in this way because /the particles in a solid can't move around/. [Particles are always moving, even in a solid they vibrate. BUT in a solid they can't move around.] [1]
6. A dog cools itself by letting its tongue hang out and panting.
a. Its body heat provides the /heat or thermal/ energy to heat the water on its tongue. [1]
b. The particles with the most energy escape into the air. These particles are at the /highest/ temperature. [You probably didn't get this one, but it's an important point. The more kinetic energy particles have, the higher their temperature.] [1]
c. Therefore as the water /evaporates/, heat is transferred from the dog to the air, so the dog gets cooler. [1]
7. List the following in temperature order, starting with the coolest: the Sun (a yellow star), Rigel (a blue star), a white star, a red star. /a red star, the Sun (a yellow star), a white star, a blue star/ [A blue flame is much hotter than a yellow or red flame. If you heat iron, white hot is hotter than red hot.] [1]
8. Thermal energy means the same thing as --- [1]
9. /Temperature/ is a measure of the average kinetic energy of the particles of an object of any size. [1]
10. /Thermal energy or heat energy/ is the total amount of energy in an object of any size. [1]
11. a. There is a glass of water, and a sink full of water at the same temperature. Which one has the most thermal energy?
Choose the letter of the right answer. (A) the glass; (B) the sink; (C) They're both the same. /(B) the sink/ [1]
b. Explain your answer to part a. [If they're at the same temperature, the average energy of the water molecules is the same, BUT the sink has more particles so its total energy is greater.] [1]
12. Why does a metal ring expand when it gets hot? /Its particles have more energy AND so they move slightly apart./ [2]
13. a. A metal spoon has been left in a pan that's cooking on the burner. You will burn your hand if you touch it. Heat is transferred from the gas ring to your hand by the process of /conduction/ [1]
b. In particle terms, how does this transfer work? /The energy is passed from particle to particle./ [1]

-The surroundings (environment) can change regularly. For example, conditions in a habitat change from bright and warm during the day to dark and colder at night.
-Environmental conditions also change through the year. Some birds fly many miles (migrate) to another country to escape the winter cold.
Organisms living in the habitat are adapted in different ways to these regular changes.

Why Exercise is Cool (You already have that)

Exercise Diary sheet

In this lesson, I'll explain what you need to do.
You will read through the materials to see where the information is. Then you will have a practice activity to see if you have understood what you need to do.

Remember: The marks for the exercise diary are not about how much exercise you do. I will give them for recording what you did and following the instructions.

The marks for evaluation are also not for how much exercise you do, but for understanding the minimum recommendation and comparing your exercise to that. You should consider overall activity, types of activity and amount of aerobic exercise.

2oA: Oxygen for Respiratiion      posted 01-11-2012
Breathing - animation
Respiration is a biochemical process that releases the energy from your food. Breathing--or ventilation--is a process that gets oxygen into your body for respiration and removes the carbon dioxide produced.

Pages. 20-21 explain how breathing happens.
When your chest cavity gets smaller (because the diaphragm is stretched and the rib cage lowered), the air in your lungs becomes denser.
Therefore the air pressure is higher in your lungs than outside your body.
Air flows out. (You exhale.)

Inhaling is the opposite. Relaxing the diaphragm means it becomes a dome shape. (Your rib cage may also move up.) This increases the size of the chest cavity, so the air in the lungs is less dense.
Therefore the air pressure outside is higher than in your lungs.
Air flows in. (You inhale.)

2oA: Fit for What?      posted 01-10-2012
Health issues for teenagers (English & Spanish)
The topic FIT & HEALTHY is in Book 9.

Fit for What?

Fitness is a measure of how well your body works. One measure is the recovery rate. This is how long it takes your heart rate to get back to its resting rate after exercise. The faster this happens, the fitter you are.

Notice that when you're fit your body systems work well together. Your cells respire all the time, but when you exercise your muscle cells need to have a high rate of respiration as this is what releases the energy for them to work.

respiration: glucose+oxygen-->carbon dioxide+water

The glucose is produced when your digestive system breaks down food. The blood carries it from the small intestine to your cells for respiration.

Oxygen is brought into your body when you inhale. Blood carries it from your lungs to your cells. But also since respiration produces carbon dioxide, the blood also carries that away back to your lungs for you to exhale.

NOTES:

Remember that in life processes, respiration and breathing aren't the same thing.

Breathing is the exchange of gases between the body and the air around you.

The respiration that interests us is the release of energy from our food.

The word equation for respiration is:
glucose + oxygen --> carbon dioxide + water
This is the same general equation as for the combustion of fossil fuels. Respiration happens more slowly, of course!

The digestive system provides the glucose (fuel) and the breathing system provides the oxygen and removes the waste carbon dioxide. The circulatory system transports the materials.
