LAB SCHEDULE for Älvkarleby AND Uppsala
Detailed time-table for Älvkarleby
For the Generator lab in Uppsala Janaina will meet up with you outside
the corridor at
'house' 5, floor 2
Any questions about this labs: Janaina.Goncalves@angstrom.uu.se, 018-471 58 04
- 6 October and 7 October first group
- 15 and 16 October 2'nd group
Departure time for Älvkarleby labs is: 8.15 SHARP on the 6th (first group) and 8.15 SHARP on the 15th (second group).
We will get back to Uppsala shortly after 17:00 the second day.
You will be divided into 5 groups with max 5 persons in each, a small report collecting the graphs and answer to the explicit questions in the instruction are required. On the lab you do in the *second slot* a *full report* is required containing introduction/background, theory, experiment results and discussion, normally not longer than 4-5 pages written on a computer. This lab you will also present in front of the rest of the group. Each group has then 15 mins at their disposal.
In the schedule we also have a study visit to the station in Älvkarleby.
You will do 4 out of the 5 laborations.
Bring: calculator, collection of formulas, pen & paper, Warm sweater, bed lennen.
