   1. Sir Isaac Newton
   2. Steve Jobs
   3. Gregor Mendel
   4. Robert Hooke
      
      
2. Mike needed extra power to open a wooden crate so he used a crowbar. What type of simple machines is a crowbar?
   1. A wedge
   2. A lever
   3. An inclined plane
   4. A screw

3. Describe Newton’s 1^st law of motion. Support your response with at least two examples.
   
   
4. Kepler’s First Law, also known as The Law of Ellipses. Summarize the law and construct a simple diagram to illustrate it.

5. Draw a diagram that illustrates what happens when a tennis ball hits a wall. Explain your answer.
   
   
6. Discuss the effects of Mendel’s two laws (Law of Segregation and Law of Independent Assortment). Support your answer with a Punnett square.

Answer Key/Rubric

1. C.
2. B.
3. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
   Answers may include, but are not limited to:

• An object sitting on a desk will not move unless pushed
•  while riding a bike you fly over the handlebars when the front tire hits the curb or a rock
•  the last little bit of ketchup will stay at the bottom of the bottle unless dislodged by turning the bottle upside down and shaking it repeatedly then suddenly stopping.

4. Kepler’s First Law states that planets rotate around the sun in an elliptical shape with the sun being located at one focus.

5. 
   
   If a ball is tossed against a wall it will bounce back at the same angle only on the opposite side.

6. The law of segregation states that two alleles for each trait separate during meiosis then during fertilization two alleles for that particular trait unite. The law of independent assortment states that a random distribution of alleles occurs during the formation of gametes.  For example, dad and mom are both heterozygous for brown eyes. If they reproduce they have a 25% chance of having a homozygous brown-eyed child, a 50% of a heterozygous brown-eyed child, and a 25% chance of a homozygous blue-eyed child.
