Task Card Use #1
Place cards in a
pocket chart with
point values on back
for game-style
review.
©2014 Nitty Gritty Science
Introduction
Task cards are a great tool for you to shake up how chapter review is done in your classroom.
Students
will LOVE the variety in which task cards can be used, such as in pairs or small groups, team games
(Jeopardy style), or even as part of daily class work.
The reason they are so effective is because there
is only ONE task per card, allowing students to focus on that single task until they have successfully
completed it.
This set of Motion and Forces task cards are meant to be copied, cut-out and laminated.
If this is your
first time using task cards, I would suggest making several sets and storing each set in either ziploc
baggies, envelopes, or punch a hole in corner and put set on a ring.
Whatever way you decide to keep
your cards, it's important to make sure they are accessible to students.
By doing this, fast-finishing
students can always grab a set and take back to seat, or when students are in lab groups I would have
them complete five cards as part of their pre-lab, then they could begin once all answers are correct.
I've also included an answer sheet in this download so students can work on one card at a time, then rotate
cards among small groups or even entire classroom.
I give each student a card and set a timer, once
timer goes off, students pass cards and work on next problem.
Once cards have passed through all
students, we review answers then make corrections where necessary.
I would highly suggest researching all the ways you can use your new set of task cards - the possibilities
are endless!! Because I'm such a fan of game-show review I've made a set of task cards that have
numbered point values so you can place on the backside of task cards placed in a pocket chart. Teams
can choose cards by point value and answer cards correctly for the win! Check my store for this FREE
download.
Enjoy the task cards, and as always, I encourage you to contact me with any comments, questions or
concerns.
Have fun getting down to the Nitty Gritty in Science Review!

Answer Key
1. Avg speed is total distance/time; constant speed means speed does not change.
2.
distance = time x speed d = 120 min x 0.10 m/s
d = 12 km
3. p=mv - momentum (kg m/s) = mass (kg) x velocity (m/s)
4. Momentum can be transferred between objects; momentum is not lost or gained in the transfer
5. Static friction
6. Rocket thrusts - action; rocket propelled forward reaction
7. A
8. Speed is the distance and object travels over time, velocity would also include direction
9. Objects at rest stay at rest while objects in motion stay in motion until an outside force acts on them.
10. Acceleration of an object is in the same direction as the net force on the object.
11. For every action there is an equal and opposite reaction.
12. net
13.
acceleration = (vf-vi)/t
(18 m/s - 9 m/s)/3 sec = 3 m/s2
14. D
15. Speed is distance over time, where velocity is speed and direction and acceleration is the rate of
change of velocity
16. speed up, slow down, change direction
©2014 Nitty Gritty Science
17. 1 kg*m/s
18. distance is how far an object has moved; displacement is distance and direction of object from start
19. answers will vary
20. gravity, friction
21. a = (vf-vi)/t
22. 2.8 m/s2
23. Law of Inertia - if car stops the person is still in motion and will stay in motion until force (seatbelt)
acts on them
24. vertical and horizontal motion
25. v = d/t
speed (v) (meters/second) = distance (meters)/time (seconds)
26. B friction
27. D. gravity
