Conclusionproblem/questionobservationsdata/results
Materialshypothesisprocedures
______1) The trucks are spreading salt on the ice.
2) The ice sprinkled with salt appears to be melting
3) The parts of ice that were missed are still frozen.
______Does salt make the ice melt more quickly?
______If you put salt on a frozen, icy road, then the ice will melt
more quickly.
______two icy patches of road near each other- observed on same day
Salt and a timer
______1) measure off two spots on a road or driveway that are
frozen
2) pour salt on one spot but not the other
3) check the ice every 20 minutes to note the melting of
ice or presence of liquid
______
Patch / 20 min / 40 min / 60 minA-salt / Still frozen / Slight glaze of liquid / slushy
B- no salt / Still frozen / Still frozen / Still forzen
______Based upon the data, my hypothesis was correct, the salt
helped to speed up the melting process.
In the experiment above…
What was the independent variable? ______
What was the dependent variable?______
What are the controlled variables?______
TUESDAY--Look at the following scenario
1)What is the question or problem?
______
2)What can’t Maggie believe? ______
3)Because she can’t believe the answer in #2…her hypothesis would be….
If acid/vinegar is added to a plant’s soil, it ______.
4)What is her independent variable?______
5)What is her dependent variable?______
6)What are her controlled variables? There are 6-7 depending on how you look at it.
1)The same______4) the same______
2)The same______5)the same______
3)The same______6) the same______
7)In what format, did Maggie decide to record her results? ______
8)How many weeks did the experiment last?______
9)What should her conclusion be based upon the chart above?
______

WEDNESDAY--
Use the word bank to fill in the blanks.
______If the pendulum weight is lowered,
then the pendulum will move faster.
______the two different positions of the pendulum
______Does the height of the pendulum weight
affect the speed that the pendulum swings?
______the rate of swinging
______same time, same twenty swings, same
pendulum, same stopwatch
______grandfather clock, stopwatch
______this chart is the ?
______Donna notices that her father can control the speed
of their grandfather clock by adjusting the height of
the weight on the end of the pendulum.
______My hypothesis was incorrect, because as the weight
was lifted higher, the 20 swings took less time.
