• Jen enters the 5th grade science fair with a
  project about candles. She asks "Will the
  temperature of the air affect how fast a candle
  burns?
• That is her Hypothesis.
• That is her Conclusion.
• That is her Problem (ac, bb, cd, dc)
• That is her Observation.

• In second grade, Jen asked "Which color of candy
  do kids prefer?
• What would be an important constant or
  controlled variable in her experiment?
• Only ask her friends.
• Use the same candy that comes in different
  colors, but the same flavor. (Ab, Ba, Cb, Da)
• Do the experiment right before lunch so the kids
  at really hungry.
• Ask each person what is their favorite kind of
  candy

Mrs. Apex's 3rd grade is learning multiplication
facts. She notices that Jay and Jen are doing
really well. She asks them if they are doing
extra facts worksheets. Jay replies that he has a
fun computer program that does multiplication
facts. Jen comes over and plays the game with
him. Mrs. Apex is almost sure that the old
fashioned way of paper worksheets is best that
Jay Jen are not the norm. So, Mrs. Apex decides
to do an experiment. Mrs. Apex divides her class
in half. There are five boys and five girls in
each group. Group A practices 5 times tables on
paper worksheets for 10 minutes each day. Group B
practices 5 times tables on the computer program
for 10 minutes each day.At the end of one week
all the children take the same quiz. The children
in Group A score 5As, 2Bs, 2Cs, 1D. The children
in Group B score 7As, 2Bs, 1F. After the fifth
week, Mrs. Apex tests the children on their
multiplication facts again. Group A (paper)
scores 3As, 3Bs, 4Cs. Group B (computers) score
8As, 2Bs. In the computer group - girls and boys
did equally well. Her hypothesis was that paper
worksheets will be the best way to teach math
facts.

• Mrs. Apex might form which hypothesis?
• If students practice multiplication facts on a
  paper worksheet, they will improve their math
  scores. (Aa, Ba, Ca, Db)
• The students like the computers more than they
  like her.
• Computers will replace teachers.
• Practicing multiplication facts on a computer
  might help test scores..

• After the fifth week, Mrs. Apex tests the
  children on their multiplication facts again.
  Group A (paper) scores 3As, 3Bs, 4Cs. Group B
  (computers) score 8As, 2Bs. In the computer group
  - girls and boys did equally well. Her hypothesis
  was that paper worksheets will be the best way to
  teach math facts.

• Jay digs a large garden for his mother. The site
  she chose is near some trees. About half the
  garden is shaded all afternoon. The other half
  gets sun all day long. In August, Jay notices
  that the tomato plants on the sunny side of the
  garden are 2x taller than the shaded ones. The
  sunny side plants have 20 tomatoes on each plant.
  The plants on the other side are short and have
  only 10 tomatoes on them. He tells his mother
  what he has noticed. This is an example of ...

• You create a science fair project. It takes 6
  weeks to collect all the data. In looking at the
  data, you find your hypothesis was wrong. You
  should

• Mrs. Membrane decided to make scrambled eggs.
  When she tried to break an egg, she found it was
  hard cooked. Jen said she could tell the
  difference without breaking the shell. Jen spun
  the first egg on the counter. It turned fast like
  a top. She touched it to stop it. It stopped. She
  spun another one. It also stopped when touched.
  The third egg did the same. The fourth egg
  turned. When she stopped it, it rotated slowly
  when she let go. Jen said it was raw.

A group of students is doing an experiment where
they roll a ball down a ramp and then measure how
far across the floor it rolls. The factors that
are the same each time are the ball the
ramp, including its length and angle to the
surface where on the ramp the ball starts
from The students do change the type of surface
the ball rolls on. The data they collected is
shown below.

• Marie and Seth are working on a lab activity
  where they are tracking some leaves that are
  floating past them in a rain runoff channel near
  their home. They have to measure how far the
  leaves travel in different amounts of time. They
  place a long tape measure along side of the
  runoff channel to measure distance. A borrowed
  stopwatch will let them record the amount of
  time. They plan to have time intervals that begin
  at two seconds, and increase by twos until they
  get to 20 seconds. The data they recorded is
  below
