Pre-Test
Post-Test
Questionnaire
1. If we place one car (assuming that the approximate length of a car is 4m) behind another along the Earth¢s circumference we will end up using
1 billion cars
100 million cars
1 million cars
10 million cars
2. If your school has the option of matching with another school on the same longitude in order to exchange data and perform Eratosthenes experiment on 20/3, what matching school would you prefer so to minimize the error on your calculations
a school that is very far from yours so the distance between the two schools corresponds to a greater central angle measured more accurately
a school that is very close to yours so the distance between the two schools is not large and thus can be measured with greater accuracy
a school that is as close as possible to equator because its stick shadow will be very small and thus it can be measured with greater accuracy
it doesn¢t matter as long as both schools share the same longitude
3. Two people decide to measure the shadow length of a 1m stick at local noon. One person performs the experiment during the spring equinox (20/3) and the other during the autumn equinox (21/9). After that they decide to share their data. Can they measure the Earth¢s circumference?
Yes, as long as they are on the same longitude and know the distance between their two locations
Yes, as long as they are on the same location
No, except if they are both on the equator at different locations and know the distance between these locations
No, because they have made their measurement at different times and the earth is not at the position it used to be
4. If I place a 1m stick at two different locations on the same latitude then
they will have the different shadow length at local noon measured on the same day
they will have the same shadow length at local noon measured on the same day
they will have different shadow length at local noon depending on their longitude
they will have the same shadow length at local noon measured only on 20th of March
5. Eratosthenes experiment was originally performed
on the 21st of June during the summer solstice
at the time of the year when the length of day and night are equal
on the 20th of March during the spring equinox
around the hottest days of the summer
6. Two cities on the same longitude
will have a local noon at the same time
will have a local noon at the same time only if they both are on the same hemisphere
will have different local noon depending on the season at that location
will have a different local noon depending if they are in the north or south hemisphere
7. If Eratosthenes lived in Europe then would he be able to see the image of the sun in the bottom of the well as he did in Syene? If yes, when or where would he observe that?
Yes, he would have seen the image of the sun in the bottom of a well if he made his observation on March 20th
Yes, he would have seen the image of the sun in the bottom of a well if he lived near the North Pole
Yes, he would have seen the image of the sun in the bottom of a well if he made his observation at a place (in Europe) that has the same longitude as Syene.
No, he wouldn¢t be able to see the image of the sun in the bottom of a well
8. If the sun rays are considered parallel when reaching the Earth then during the winter solstice (21/12) they are
perpendicular to the ground during local noon at any location on the Tropical of Cancer
perpendicular to the ground during local noon at any location on the Tropical of Sagittarius
perpendicular to the ground during local noon at any location on the Equator
perpendicular to the ground during local noon at the South and North Pole
9. Assuming that the sunlight comes from a very long distance away, Eratosthenes experiment can be the basis to prove that:
the Earth rotates around itself
the Earth is not flat
the Earth is a sphere
the Earth rotates around the sun
