B) 5 measurements of a meter stick which measure the length as 80cm, 79cm, 81cm, 82cm, 78cm.
C) 5 measurements of a meter stick which measure the length as 90cm, 110cm, 109cm, 91cm, 100cm
D) 5 measurements of a meter stick which measure the length as 80cm, 95cm, 50cm, 130cm, 200cm.
<ref name="dif">I like the difference between questions A and B. I'm not sure the others are as clear. Need more info to make change</ref>
Which of the following is likely to have the least impact on a model of a ball dropping:
A) Rate of acceleration due to gravity
B) Size of the ball
C) Height of the ball
D) Whether or not the ball is attached to a parachute
About how many squirrels are on Earlham's "front" campus:
A) 1 to 10
B) 10 to 1000
C) 1000 to 100000
D) 100000+
<ref name="front campus">How do you define "front" campus? I think it might be helpful to give them the area of campus so they're not estimating two things at once. Front campus is the area with buildings on it.</ref>
