“I want a tree“ Monitoring the germination of sunflower seeds
We got micro bit with the extension for watering (pump) and wires with nails.
First we brought together all the components.
When we brought them together, we connected micro bit to a computer and started programming.
micro:bit, a new pocket-sized computer that allows everyone to write codes, also it allows computer hardware editing and use via computer software
We bought sunflower seeds (Helianthus annuus)
We programmed micro bit to measure current resistance through nail, that is to calculate the level of humidity.
We programmed 4 hours at school altogether.
27 February 2018
We took two flower pots that day and put potting soil in them.
The middle-years teaching pupils sowed 30 seeds of sunflower in the pot.
Also, they set micro bit to measure the level
of humidity and the irrigation system „drop by drop“.
27 February 2018
The primary teaching pupils
sowed 30 seeds of sunflower in
another pot, but without the irrigation system.
2 March 2018
We measured the level of humidity with micro bit
irrigation system; it was 900 (almost dry).
6 March 2018
The next measurement of the level
of humidity with micro bit irrigation system
The level of humidity was 776, 23
plants sprouted, the height was measured
The maximum height of a young plant
was 16 cm, the medium height: 6 cm,
the minimum height: 2 cm
6 March 2018
The control pot: 1 plant sprouted, height: 2 cm
9 March 2017
Watering was done, the level of
humidity was 794, the maximum height:
22 cm, the medium height:
16 cm, the minimum height: 13 cm
9 March 2018
The control pot: 8 plants sprouted, the maximum height: 15 cm,
the medium height: 13 cm, the minimum height: 8,5 cm
14 March 2018
The control pot: 8 plants sprouted,
the maximum height:
20 cm, the medium height:
17 cm, the minimum height: 14 cm
14 March 2018
We measured the level of humidity with micro bit
irrigation system again, it was 900 (almost dry)
The maximum height of the sunflower was 24 cm,
the medium height: 19 cm, the minimum height: 16 cm
