Challenge 5

Paper texture

- Pot A1 - Pot A2 - Pot A3

- Pot B1 - Pot B3 - Pot B2 - Pot B4

In pot A1, seeds germinated and then the plant rotted. In pot A2, seeds germinated. In pot A3, seeds didn't germinate.

In pot B1, pot B2, pot B3 and pot B4,  seeds germinated.

-We put seeds in two pots with soil and placed one in the window and the other in a dark room.

-We put seeds in two pots with soil and placed one in a warm spot but the other one outside where night-temperature went below zero and up to 5°C at day.

-The seed which was placed in a warm spot germinated but the one outside in the cold didn't.

At the beginning of the experiment (observing the seeds), we thought they were seeds of:

Finally, we think that they are seeds of sunflower

-We put seeds in three pots with soil. One was watered very generously, one got a little splash every day and the third one didn't get any water.

-We put seeds in four pots, one with soil, one with sand, one with cotton and one with torn paper and watered a little every day.

- The first one germinated but only a little, the second one did well but third one, which didn't get any water, didn't germinate.

-The seed in the soil germinated and sand germinated and developed a plant.  The seed in cotton germinated a little but the seed in the torn paper didn't germinate.

-The seeds need water to germinate but not too much

Conclusions: Plants can grow in sand and soil but not in cotton and torn paper

In pot C1 and in pot C2, seeds germinated.

In pot D1, seeds didn't germinate. In pot D2, seeds germinated.

Finally, we think that they are seeds of red hot chilli pepper. We haven't yet obtained the fruits but we found by comparing the leaves of the plants that have grown with internet photos.

-broccoli, -beetroot, -olive tree, -mint, -basil, -green beans, -red beans, -zucchini, -peppers, -thyme, -cucumber

Conclusions of the Icelandic germination lab:

-We found out that warmth and water are essential for seeds to germinate but they can do without light and soil. The plants thrive best with good soil, moderate watering, warmth and light.

Conclusions of the French germination lab:

The seed doesn’t need soil or light to germinate because it uses its reserves (cotyledons). However, the seed needs water and heat. We sowed seeds using compost, and we found that the fastest growing plant was in the pot with compost.

- We put the seeds into the soil, placed the pot inside a cupboard in dark and watered the seeds regularly.

- We put the seeds into the soil, placed the pot outdoors (-3 C). We watered the pot regularly.

- To germinate the seeds do not need light.

- To germinate the seeds need warmth - at least + 10 C.

Conclusions of the Estonian germination lab:

We seeded the seeds into the pots at school. During the lockdown because of corona epidemics, the students took care of the pots at home. When talking about the control pots with their teacher, the students made the following conclusions: - The seeds may germinate without soil or light, but they definetely need water and warmth. - If the seeds germinate (by using the reserves in the seed), they need the soil and the light to grow up. - In the dark and in the sand, the seeds can germinate but the plants are very small, weak and fragile. To grow into strong and tall plants, the seeds need light and good soil though.

Finally, we think that they are seeds of rapeseed

- mini blueberries - sunflower - white dead-nettle

- We put the seeds into the soil and placed the pot on the windowsill. No water was given. 

- We put the seeds into the sand and placed the pot on the windowsill. We regularly watered the pot. 

Conclusions: To germinate the seeds do not need soil.
