Example 1:
A student hypothesizes that the mass of a substance affects how the temperature of the substance changes
when it is heated. The student uses the following procedure to test the hypothesis:
a. Each sample is initially at room temperature before heating.
b. Each sample is heated for the same amount of time with the same heat source.
c. The final temperature is measured for each sample.

Example 3:
In humans, acondroplasia (“dwarfism”) (D) shows incomplete dominance over normal (N). A
homozygous dwarf (DD) person dies before the age of one. A heterozygous (DN) person is dwarfed. A
homozygous normal (NN) individual is normal. A heterozygous dwarf man marries a dwarf heterozygous
woman……..

a.
100% d.
25%
b.
75% e.
0%
c.
50%
ANSWER: DOK 2

Example 6:
Which of the following correctly traces the development of atomic theory in order from the oldest to the
most recent models and discoveries?
a.
1. All matter is made of atoms that are solid spheres of matter.
2. A small, dense and positively charged nucleus was found using alpha particles and gold foil.
3. The neutron was discovered.
4. Electrons are negatively charged particles that are scattered throughout a positive atom.
5. Electrons are thought to orbit the nucleus in specific energy levels.
6. The electron cloud model suggests probable locations of electrons in the atom.
