I STARTER: It is important that we be able
to convert time from days to hours to
minutes to seconds. Make the below
conversions and show your work!
1. Convert 7 days into hours.
2. Convert 8 ½ hours into minutes.
3. Convert 1 hour 45 min’s into seconds.
II PRACTICE:
Bubble Gum Physics Lab
Glue in Bubble Gum Physics lab and complete.
III APPLICATION:
• Insert notes on graphing and complete graph
from Bubble Gum Physics Lab data.
Variables
• Variables are factors, conditions, and/or
relationships that can change or be changed.
(Growing plants with different amounts of
water.)
Independent Variable
• a factor or condition that is changed on
purpose. (Different amounts of water). [ON
THE HORIZONTAL AXIS].
Dependent Variable
• a factor that might be affected as a result of
the change in the independent variable.
– Example(Height of plants depending upon how
much water the plant received.) [ON THE
VERTICAL AXIS]
Controlled variable
• a factor that is not changed. (Same soil and
same amount of light each day.)
• Data is the information collected from
observations.
• Bar graphs are used to compare information
about similar things.
• Line graphs are in which line segments are
connected to show changes that occur, often
over a period of time.
• An interval, increment, or scale is the increase in
size or number.
• The horizontal axis is found on the bottom of the
graph and is used to show the manipulated
variable.
• The vertical axis is found on the side of the graph
and is used to show the responding variable.

IV CONNECTION:
Put into place a plan using speed, time, and
distance calculations for a road trip.
 This road trip will be a total of 75 miles and you will
be able to keep a steady 70 miles per hour
 You will also need to factor in 2 stops that will add
on an additional 5 minutes each.
Show your math to calculate how long the trip will
take and tell what time grandma should expect
you to arrive if you leave at 8:00 am.
V EXIT:
• Write a well written paragraph (5 sentences!)
summarizing what you learned today. Also, list
any questions you may still have about Speed,
Time, & Distance.
