Day 4 Q 1
To count the total atoms, you have to count the atoms for each element in the molecule.
How many different elements are there?
3 (H, S, and O)
H = _____
S = _____
O = _____
Total = _______ 7 2 1 4 7

3. Day 4 Q 2 z True, so we can’t pick it True, bubbles showed up
When you have to pick an answer that’s not supported, it’s best to eliminate the other answers, one by one. A? B? C? D?
True, so we can’t pick it
True, bubbles showed up
FALSE (notice temp in description
True, temp. went up in HCl

4. Day 4 Q 3 z What is X pointing to? The nucleus.
What “subatomic particles” do you find in the nucleus?
Protons and Neutrons
So only one of these answers could possibly describe either a proton or a neutron.
neutron
Protons have mass
Nothing in the nucleus is negative
Any particle in the nucleus has mass.

6. Who is Isaac Newton?

7. What did his first experiment test?
What did Isaac Newton think when he saw the apple hit the ground?
What was Isaac Newton’s first theory?
Who did Isaac Newton work with to continue studying gravity?
What did Newton develop as a result of his studies?
What did Isaac Newton’s Law describe about our world?
Investigating how wind made an object move.
Why do things fall?
Could the same force that pulls an apple to the ground be the same force that pulls the moon to our planet causing it to orbit.

Newton’s Three Laws of Motion
Describe how everything in our universe moves and interacts with each other.

9. Newton’s 3 Laws of Motion

10. What causes every change in motion?
What two forces help stop a moving object?
Summarize Newton’s first law of motion.
What does Newton’s second law of motion state?
Explain Newton’s third law of motion and provide an example.
A force
Gravity and friction
Motion only changes with an unbalanced force.
Force = mass x acceleration
For every action there is an equal and opposite force: digging in your feet when playing tug of war.

15. Friction
The resistance that one surface or object encounters when moving over another surface.
Goes in the opposite direction of the moving object.

16. Inertia A tendency to do nothing or remain unchanged.
Inertia is a property of matter.

17. Examples of Newton’s 1st Law
Book sitting on a shelf.
