Control Bean
Day 1: Planted bean in soil and agreed with group amount of water to be added every other day. Watered seed today-here goes!
Day 3: Seed has germinated! Added second amount of water today. Was quite exciting to see something sprout from the soil. Hopefully as the control plant, mine will grow quickly and healthily!
Day 5: Plant is growing quickly. It has healthy looking green leaves and appears to be growing quite straight. It is now 70mm tall….Success!
Day 7: Plant seems to have stopped growing for some reason, or else is not growing as quickly. (80mm)Am not sure why this is, think I may have overwatered it the other day. Am now quite worried that plant will stop growing/die. Added slightly less water today just in case.
Day 9: Control bean is back on track-it has grown quite a bit over the last 2 days and sprouted a few more leaves. It is now 130mm tall. It still looks healthy and strong. I am relieved!
Day 11: This plant is growing very rapidly…I may have to remove it from my windowsill in order to see out the window! It is now 175mm in height and full of leaves. Obviously, the combination of regular water and sunlight has done the trick- I wonder how the other beans have fared with salty water and tea, etc!
Day 13: The bean plant is now at the majestic height of 200mm (more or less-there are leaves poking out everywhere!) It is perfectly green, straight, strong and healthy. As this is our control bean, I am delighted that it has sprouted and grown so uneventfully, apart from the slight hiccup in Day 7! I feel quite proud of my plant!
Salty Bean
The bean has germinated!
My bean has germinated too! It is about 2.5 cm long and has also grown towards the light. I will begin feeding it a salty diet as of today.
Interestingly, though an aside from the main experiment, the first salt bean that I mistakenly fed salt water to from the start, never germinated. The seed is pulpy and colourless. This might help confirm our predictions for the new salt bean…
Salty Bean
Quick up date on Mr Salty for you!
He’s around 2 inches tall, and seems to be growing but very very slowly. Also, interestingly, since being fed a high-salt diet his leaves seem to be turning black and crispy at the ends. Hopefully the photo is clear enough to give an incling of what’s going on! I have a strong suspicion that salt and beans don’t mix!
Salty Bean (again) !
The dying salt bean
Salty Bean has taken a turn for the worse. It stopped growing several weeks ago, and started to show black spots on the leaves. The leaves have now shrivelled up and turned black, and I wouldn’t be surprised if in a couple more weeks the plant was dead. Not surprising, since we know that the salinity of water in bodies such as the Dead Sea and the Salt Lakes prevent all but the hardiest life forms from surviving, and this bean is recieving a very high concentration of salts in the water solution.
Salty Bean is no more
Salty bean has died. It couldn’t cope with the salt levels, turned black and crispy and was no more. This agrees with our hypothesis that salt would not do the beans any good.
Tea Bean
My Bean has sprung into action! It is 2mm in height and very green. I have been feeding it tea for two days. It has grown towards the window because of the light. I will keep monitoring its height and colour.
Sugar solution bean
During the first few days of growth, the sugar solution appeared to facilitate the growth of the bean shoot (see graph for results), however as time continued, the sugar solution crystalised in the soil and the growth of the shoot slowed.
As you can see from the photos below, by Day 14, the shoot was limp and turning brown and you can see the sugar crystals on the surface of the soil.
