Science WebQuests from all years
Purpose:
To be able to:
recognize that movement is observed according to a frame
of reference.
describe motion and calculate speed and velocity.
interpret graphs on constant velocity, acceleration,
negative acceleration (deceleration).
be able to animate motion using the velocities of different
objects(Lab on internet).

Resources Needed:
You will need a computer connected to the internet as
well as sheets found on this webquest. Many activities require plugins
for your browser.
You will need Macromedia's - Flash
and Shockwave plugins.
Your
Task:
-
Have you ever wondered how fast things are going? Well, take
a look at this page on motion.
-
Well that was nice to know. But what does that mean?
In order to understand how fast you are moving you need to be able to compare
it with some thing else that is not moving or is stationary. That stationary
object can be called a frame
of reference.
-
To help you better understand frame
of reference, you will want to compare how fast two students are tossing
cookies (View three frames
and return)
-
Now that you have a better sense of a frame of reference,
just what is motion? You might think it is moving from one place
to another, and you are almost right. But, in science, we have a name for
the study of motion. It is called Kinematics.There
are some new words that you need to know.
-
Use puzzlemaker
to make a crossword puzzle for the following words : scalar,
vector, distance, displacement, speed, velocity, acceleration, kinematics,
frame of reference. Get
the definitions for the words as you view the lesson 1 on Kinematics
(lesson one only)
-
After you have mastered lesson 1, you should have a good
idea of the vocabulary and should be able to answer this Question
(1)
-
That one was easy. Try this
Question
(2)Try this Question (3)
for extra credit.
-
If you are still unsure of the difference between speed and
velocity, try this website on speed and velocity
-
Now try the word problems on speed and velocity from
the work pagethat you can print
out.
-
Now that you have a knowledge of how to do word problems,
let's figure out how to recognize a graph representation of constant speed,
velocity and acceleration.
-
Can you guess which line is constant velocity, and which
one is accelerating faster?
-
To see if you are correct, go to lesson on graphing velocity
and acceleration. Place the following
different velocities at 0,5,10,and15.seconds in the tutorial and notice
the lines that are similar to the graph above.
-
10m/s,10m/s,10m/s,10m/s
-
0m/s,5,m/s,10,m/s,15m/s
-
15m/s,10m/s,0m/s 0m/s
-
10m/s,5m/s,0m/s-5m/s
-
0m/s,1m/s5m/s,10m/s
-
2m/s,5m/s,-5m/s, -8m/s
-
Draw the five graphs on graph paper and label whether the
graph is showing constant velocity, acceleration, or deceleration.
-
For lab credit, do the lab
on animating motion.
Do activity 3, but you may have to look at the beginning of the lab to
understand how to do activity 3.
 Now
that you have mastered the understanding of speed, maybe you would like
to try your hand at some of these simulations.
1. Reaction
time while driving- but don't crash
2. Frame
of reference
3. Velocity
composition
*** For all your work, enjoy this fast action game Skyracer
*** - requires
Macromedia plug-in
How
about testing your reaction time while trying to hit a baseball?
Assessment:
Please complete and hand in work together for credit.
Crossword puzzle showing definitions of words
Questions 1, 2,and 3 (for extra credit)
Six graphs from the tutorial with label for constant velocity,
acceleration, and deceleration
Work sheet with 5 problems( show work)
