You Passed 8th Grade Science

Congratulations, you got 8/8 correct!

Good God I hope so! It would be sad if they could give you a PhD in science without being able to pass the 8th grade...

Minor quibbles:
1) It's nucleus. Not "nuclues"
2) 8th grade is PHYSICAL SCIENCE, so questions 2,4,5,and technically 6 (see below) don't count.
3) Question 6: What is the charge of a neuron? Umm? As if? The right question for the correct answer is "What is the charge of a neutron?". However, as asked, the correct answer is: depends on the ion concentration and the firing state.

UPDATE!!! Answers below the fold! 1. Mike is converting potential energy to kinetic energy. A.

2. This is a "choose the best answer" question. While B, nucleus, is technically right, the correct answer is C, chromosomes. The DNA makes up the chromosomes.

3. B, Helium (He). Which is an element. The other choices are compunds made up of multiple elements (Water-- H2O; Salt-- NaCl, and Chocolate--C7H8N4O2).

4. The nucleus is the "brains" of the cell, so the correct answer is B, direct the activity of the cell.

5. The answer is D, High Rainfall, stable temperatures. Think Rainforest.

6. The answer is C, 0. A neutron has no charge, just mass.

7. Volume, mass, and diameter are constant properties since the bowling ball is a solid. However, weight is a measurement of the force exerted on the object by gravity. To clarify, mass tells us how much of something is there, weight tells us how much force we have to use to move it in any direction other than down. So, since gravity on the moon is about 1/6 Earth's gravity, the answer is A, weight.

8. More Moon gravity. The answer is B.
