Transcript Slide 1

This is a PowerPoint to demonstrate how to use the STEM top trumps.
The harder set will require some rearranging of the formulae. The easier
set has a tiny bit of rearranging in but a lot less.
The formulae should all be ones they have met/will meet in Physics.
You could insist on using the names for what the letters stand for with
more able sets. Similarly you could insist on using units.
P = IV
V
R=
I
d
s=
t
F = ma
P = IV
P is Power (Measured in Watts)
I is Current (Measured in Amperes (or Amps))
V is Voltage (Measured in Volts)
V
R=
I
d
s=
t
F = ma
R is Resistance (Measured in Ohms)
I is Current (Measured in Amperes (or Amps))
V is Voltage (Measured in Volts)
S is speed (Measured in metres per second)
d is distance (Measured in metres)
t is time (Measured in seconds)
F is force (Measured in Newtons)
m is mass (Measured in Kg)
a is acceleration (Measured in metres per
second per second)
Lets use
P = IV
I got
460
(Watts)
P = IV
F = ma
V
R=
I
d
s=
t
…ok , so we need
to calculate P
I got
18… you
win
Lets use
F = ma
I got
1.875
(ms-2)
P = IV
F = ma
V
R=
I
d
s=
t
…ok , so we need
to calculate a
I got 10…
I win!
Ideas for how to make the activity work well:
Pupils to use Mini white boards for working. Pupils wait till both have done
their working before revelling their answers. If a pupil spots a mistake in
their opponents working then they win the card regardless of which card
gave the largest answer.
Before starting agree with class what they will do if substitution leads to a
draw.
Pupils my need reminding how to rearrange before hand.
After the activity you could discuss which answers were sensible quantities
(some answers will come out ludicrously high or low for real life values).
