The task
To measure the tree height
6Slide7
To measurer something means to compare it with some reference standard
Direct measurements of height;
Modified “height’s measurements”;
Indirect measurements (height through velocity, time, age);
Statistical survey

The number of pine needles
Statistic survey;
To count the number on one
unbranched twig and then multiply by number of twigs;To find out average value for ten (?) twigs and the multiply by its numbers;
To find out the volume of the tree, then reduce it in N (?) times and divide for volume of one needle.

From simple objects to Big Physics
25Slide26
ConclusionsThese cases are open-ended, really stimulating students’ creativity;
Interplay of students’ alternative ideas;
Deriving new dimensions of school and university students and teacher interaction;
The objects under investigation are ordinary available, special equipments or devices are not necessary;
We don’t need special laboratories and rooms; outdoors environment is mostly enough;
The cases are not artificial; each of them appears from the pure natural phenomenon or process;
From simple objects to Big Physics.
