Alex noticed on the campout that Joni’s face had darkened from the sun. She learned that every time we are out in the sun, our bodies make Vitamin D. The Vitamin D made by the body is considered to be natural. But Vitamin D tablets can also be made in a factory.
Which statement is true regarding the chemical composition of these two substances?
1. The Vitamin D made in our bodies does not work correctly.
2. The Vitamin D made in our bodies is different from that made in a factory.
3. The Vitamin D made in a factory contains different elements than what is made in our bodies.
4. Both Vitamin D’s contain the same elements and in the same arrangements, so they work the same.
4. Both Vitamin D’s contain the same elements and in the same arrangements, so they work the same.

Do you think CO2 and C2O2 are the same type of substance? If they aren’t, how would you know they were different?
They are not the same substance because one has more Carbon atoms than the other.

A person claims that aspirin is not “natural” and refuses to use it to relieve their pain. Which of the statements best refutes (argues against) this person’s claim?
1. Aspirin can be considered natural because it is made from salicylic acid which comes from a tree.
2. Aspirin is made in a laboratory so it is pure.
3. Aspirin has been used to relieve pain since the 5th century BC
4. Salicylic acid causes stomach pain
1. Aspirin can be considered natural because it is made from salicylic acid which comes from a tree.

What is one similarity and one difference between these two solid structures. 
similarities:
-Both are in a 3-dimensional structure with attractions (or bonds) between the atoms in layers and top to bottom.
For differences:
-Substance 1 is made of two different types of atoms so it is a compound. But Substance 2 is made of only 1 type of atom so it is an element.

Think back to the M&M lab. How was the rate of dissolving different when the chocolate candy was placed in hot vs. cold water?
How water caused the candy coating to dissolve quicker.
Cold water, the coating still dissolved but it was slower.
*Hot molecules move faster than cold.*
