Hypothesis the temperature of the ball does
effect the height of the bounce.

• 1. PURPOSE Does the temperature of the ball
  effect the height of the bounce?
• 2. I accept my hypothesis, the temperature did
  effect the height the ball bounced. At freezing

15
How Prokaryotic and Eukaryotic cells differ

• Prokaryotic cells do NOT have a membrane around
  their nucleus therefore they do NOT have a
  nucleus. Prokaryotic cells do NOT have a
  membrane around their ORGANELLES, therefore they
  do NOT have organelles.
•  
• Eukaryotic cells DO HAVE a membrane around their
  nucleus, so they have a nucleus. Eukaryotic
  cells DO have membrane around their organelles,
  therefore, they do have organelles.
