13 Vegetables That Magically Regrow Themselves

13 Vegetables That Magically Regrow Themselves.

I found this link on pinterest so long ago and I have been desperate to bring it to light and actually test each one! The 13 vegetables are divided into easily do-able (spring onions, garlic, romaine lettuce, carrots, basil), feasible (lemongrass, celery, onion and bok choy), feasible if you’re a plant magician (avocado, sweet potato, ginger roots and pineapple) – I think it’s these that I really want to try, including the 3 years for pineapple!

It’s Buzzfeed so each vegetable has it’s own link. The first two levels could be really good fun to do at home or with a STEM group, or a standard lesson, too. Perhaps the top level are only really for at home! Or school technicians over a summer holiday!

I found this on pinterest and am so intrigued to see how well this works. Ellen, the author, suggests using radish seeds, but I’m wondering if in a STEM environment it might be more useful and cost effective to use cress seeds. We’ll have to try it out with that.

I love the fact that you tie off and make a contained “world” within the balloon. I can imagine asking a group what a plant needs to grow and then asking them if the seeds have all of that inside of the balloon.

I also love the idea of also growing the plant outside of the balloon, to see how the balloon affects the growth.

Could this also work on a larger scale to demo phototropism? Paint the balloon all over, or on one side. Or just use a dark coloured balloon.

I seriously cannot wait to try this!

And of course, this experiment is perfectly suited to be done at home – that’s what Ellen did. We’re just going to adapt it for inside of education. Or try to!

I found this on a random google search where I was actually looking for something else and I know that I have found a few plant growth topics, but this one is a bit different.

The standard practice in schools to test plant growth is to use nutrient deficient solutions on already grown plants, or on cress, and we often find that we don’t get amazing results. Through mainly pinterest, I have found “at home” versions where you use water, salt water, sugar water, vinegar, etc – common household liquids. Obviously, if you’re trying to teach the science behind the nutrients themselves that are needed, the “at home” versions won’t help.

If, however, you just want to introduce how plants grow rather than what they need nutrient-wise to grow, then this newly found solution can easily be added on: aspirin!

Apparently there is loads of research into how aspirin can help tomato plants, but this “science fair” topic is about testing aspirin to see if helps plants grow. This would be a lovely add on to the other household liquids that cress seeds could be grown with.

You just have to be careful with the aspirin when it comes to children. Definitely one to add on to the to-do list!

This sounds like an amazing fun little “at home” activity – measuring the growth of a plant. I wonder if you could also measure the root growth? I know that they tend to be windier and far more tangled, but maybe an approximate growth?

I also love the idea given in the post about looking for patterns of growth and comparing different plants. We have windows facing east and west, would that create a difference in growth rates? It would be good for a Biology Plants unit and for STEM.

It should even work for cress in a test tube (that way you don’t have to worry quite so much about remembering to water them!) over a few weeks perhaps.

I really like this idea. We already use a version where we grow plants lacking certain nutrients (without phosphate, without nitrate, etc), but for a STEM session or science at home, this might be far easier to come to grips with. In the experiment Lemon and Lime did, they used tap water, river water, salt water, carbonated water and soda. I would love to add in acidic and an alkali water (both can be made easily at home).

Then, measure the plants and their growth over a week or two – obviously at home that is far easier to do each day and in STEM the changes might be huge within a week, but I still think it would be so fun to do! Plus, we sometimes have an issue with getting our STEM members to make predictions and they do it during/after the experiment (you know, when they can’t be wrong! Haha!) and this one is ideal because they won’t see any results for a week!

I think it might also be far more visual than the in-school version that we do! It might also be worth trying in test tubes with cress seeds as the watering them aspect is never as much of an issue and the growth is far quicker.

 

Plant an Odds-and-Ends Garden

Some “at home” ways to grow new vegetables. With beetroot, slice the top off and keep the green shoots attached, rinse it and place it in a shallow dish of water.

With celery, cut a bunch of celery down until you have only 3 inches of the base and put it in a shallow dish of water. Within a week, leaves should be growing out of the center. The advise is to peel away rotting stalks as it grows.

Basil stalks can be put into tall glasses of water (small leaves not submerged) and after a few weeks roots should emerge – this should be good to study and visibly see root growth.

Apparently garlic cloves can be fully emerged in water and roots will appear in a few days, sprouts may take a little bit longer, but still in a clear container this would be perfect and perhaps easier to study root growth.

Cut a washed sweet potato in half and put it in another shallow dish of water. Leaves appear in 2 weeks.

Some of these would be perfect for a STEM session – celery, beetroot and garlic for definite, with the others perhaps taking a bit too long. And of course they’re all amazing ideas for Plant Biology and for doing at home. I have a pin somewhere about other fruits/vegetables that you can re-grow at home so I will try and find that to add to this topic.

Until then, I can try out this one!
