Question 1 of 10
1. OK, first of all, we're off to the chemistry lab! We learn all about the properties of elements and compounds. Our teacher asks us what two elements common table salt is made out of. What ARE they? Hint


Question 2 of 10
2. Next, we're going to observe the microscopic world! We find all sorts of interesting infomation. After being lectured about all the the different functions of the organelles of the cell, our teacher asks us what organelle is known as the 'brain' of the cell. What IS it? Hint


Question 3 of 10
3. Next, we go on to our botany class. We learn all about plants and the amazing photosynthetic processes they undergo! After the lectures, our teacher asks us what gas plants contribute to the earth's atmosphere. What IS it? Hint


Question 4 of 10
4. Right before lunch, we're off to physics. Mr. Jimmy, our physics teacher asks us what the main particles of an atom are. What ARE they? Hint


Question 5 of 10
5. After lunch, we must go back to chemistry class. Our teacher asks us what products are, as a general rule, the result of an acid and a base reacting together. What ARE they? Hint


Question 6 of 10
6. So, we're about to go to our biology class, but wait, we forgot our physics books! So, going back to our physics classroom, Mr. Jimmy asks us what stored energy is commonly called. What IS it? Hint


Question 7 of 10
7. So, we arrive at Mrs. Diane's biology class and learn loads of stuff! She asks us what measurement unit microbiologists use when they want to measure something really small (like a bacterial cell!). What IS it? Hint


Question 8 of 10
8. Next class is environmental science! We learn all about greenhouse gases and the increasing danger they can do to the enviornment. The teacher asks us what is NOT a greenhouse gas. What IS it? Hint

Quiz Answer Key and Fun Facts
1. OK, first of all, we're off to the chemistry lab! We learn all about the properties of elements and compounds. Our teacher asks us what two elements common table salt is made out of. What ARE they?

Answer: Sodium and Chlorine

Table salt (sodium chloride) is made out of the elements sodium and chlorine. It is made up of one atom of each. Its chemical formula is NaCl. A little salt is needed for all human beings, but too much salt can lead to problems, like high-blood pressure.
2. Next, we're going to observe the microscopic world! We find all sorts of interesting infomation. After being lectured about all the the different functions of the organelles of the cell, our teacher asks us what organelle is known as the 'brain' of the cell. What IS it?

Answer: Nucleus

The nucleus controls all the reactions within the cell. The chloroplast is the organelle in plant cells where photosynthesis (where radiant energy from the sun is converted to chemical energy) takes place. It contains pigments known as chlorophyll. Chloroplasts are only found in plant cells.

The mitochondria is where respiration occurs. All cells (not just plant cells) contain mitochondria. All cells also have a cell-membrane. This selectively allows some materials to pass, and not others, such as starches.
3. Next, we go on to our botany class. We learn all about plants and the amazing photosynthetic processes they undergo! After the lectures, our teacher asks us what gas plants contribute to the earth's atmosphere. What IS it?

Answer: Oxygen

Plants keep the oxygen content stable by photosynthesis. They release oxygen gas into the atmosphere as a by-product of photosynthesis. Denitrifying bacteria contribute to the vast amount of atmospheric nitrogen in the atmosphere (78% of the earth's atmostphere is nitrogen). Carbon dioxide is needed for photosynthesis, but isn't released into the atmosphere by photosynthetic processes.
4. Right before lunch, we're off to physics. Mr. Jimmy, our physics teacher asks us what the main particles of an atom are. What ARE they?

Answer: Neutron, electron, and proton

The proton has a positive charge, the neutron has no charge, and the electron has a negative charge. The electrons are on the outer orbit of a atom. A covalent bond exists when electrons are shared between atoms. This is the most common form of chemical bonding. All matter is made out of atoms. Chemical elements contain only one type of atom. All the chemicals in a cell are made out of atoms, so atoms must be VERY, VERY tiny indeed!
5. After lunch, we must go back to chemistry class. Our teacher asks us what products are, as a general rule, the result of an acid and a base reacting together. What ARE they?

Answer: Water and a salt

Whenever an acid and base combine, they almost always produce water and a salt. However, water and carbon dioxide are occasionally produced. You have probably heard of the volcano experiment! Well, when you mix baking soda (a base) and vinegar (an acid) together, the end products are water and carbon dioxide.

However, it is mostly water and a salt (such as sodium chloride) that are produced in this type of reaction.
6. So, we're about to go to our biology class, but wait, we forgot our physics books! So, going back to our physics classroom, Mr. Jimmy asks us what stored energy is commonly called. What IS it?

Answer: Potential energy

Potential energy is stored energy. Kinetic energy is moving energy. Radiant energy is the energy the sun gives off! Chemical energy is the energy created by a chemical reaction.
7. So, we arrive at Mrs. Diane's biology class and learn loads of stuff! She asks us what measurement unit microbiologists use when they want to measure something really small (like a bacterial cell!). What IS it?

Answer: Micrometre

To get a micrometre, you multiply the amount of millimeters by a 1000. So, if the answer in millimeters was 3, it would be 3000 in micrometres! A micrometer is one millionth of a meter - very, very small!
8. Next class is environmental science! We learn all about greenhouse gases and the increasing danger they can do to the enviornment. The teacher asks us what is NOT a greenhouse gas. What IS it?

Answer: Nitrogen

Nitrogen is NOT a greenhouse gas, however nitrous oxide is. Greenhouse gases contribute to global warming. Deforestation is a big contributer to the greenhouse effect.
9. OK! Next we must go back to our botany class! Our teacher asks us which class of metaphytan plants contain flowers. What class IS it?

Answer: Angiospermae

All plants in the class Angiospermae contain flowers! These flowers attract insects and other small organisms to carry their seeds. In this mutualistic relationship, the plants get their seeds distrubuted within the area leading to diversity. In return, the animals get fed with the fruit that the plants contain. Gymnosperms do not contain flowers. Both gymnosperms and angiosperms belong to the phylum Tracheophyta. Because it is not a class, but instead a phylum, that is not the right answer!
10. It's the last class of the day! We learn all about the human body. We learn about the organs and their functions. Mrs. Waters asks us what system our brain is in. What IS it?

Answer: Nervous system

The nervous system contains the brain. The circulatory system contains the heart. The digestive system contains the small and large intenstines. The respiratory system contains the lungs and all the organs that help us breathe! We need all these organ systems to survive! I really hope you enjoyed my quiz! I hope you learned LOADS of new infomation!
