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!
Circulatory System Lesson. / How to Make a Human Heart
I found this a while ago, but still haven’t got around to trying it out. The picture looks like it should be a really good heart model, and if it means that we don’t have to use any of our budget to buy a working heart model, well it must be good. Right?
The equipment is all stuff that you can easily find at home (recyclable material, too) so also easy that you could save enough to get a whole class or STEM group to do. And, of course, there’s the option of doing it at home just for fun or extra credit work.
This is one we need to try in the summer!
Fun Science Experiment! – Learning how plants absorb water! –.
I want to bring this blog to note because I think it would be far more cost effective when we usually demonstrate how plants absorb water. Normally, we buy a bunch of flowers and either put them all in one vase of artificially coloured water, or separate them between two colours. Normally only blue and red. We might also do the same with a packet of celery. Celery is good because you can cut the stem and see the colour going all the way through.
However, I was drawn to this particular blog and the idea from a photo of cabbage leaves in different coloured water. With celery, only blue and red ever tend to really work, visibly. Well, Paging Fun Mums has clearly got red, blue, green and yellow to work amazingly well with cabbage leaves. I also think that it would be far easier to ensure a whole class could set up their own set as a cabbage would go further than a bunch of flowers. They were apparently only left overnight, which is probably what we would do.
I just really want to try the cabbage!
TED-Ed and Periodic Videos.
This specific link to TED-Ed shows a periodic table, where every single element has a video link! The videos are from the University of Nottingham and all subtitled, varying in length and type of content. Randomly, I watched the videos on Mercury, Molybdenum and Oxygen. Molybdenum’s was only about a minute long, Oxygen was 6 minutes. They were all very informative, with Mercury and Oxygen having some “fun” science being shown in them so obviously it will all depend on which elements can have more visual content.
But, if you ever need to start off a bit of research on an element, or to prepare a lesson on one (especially a rarer one), this is the perfect starting location. Where else would you learn the meaning behind Mad as a Hatter?
Balloon Greenhouse | Activity | Education.com.
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!
How to Make Magnetic Slime – Frugal Fun For Boys.
I’m sure that most science departments have a whole array of magnetic toys, we certainly have – we may even have some magnetic slime. However, to be able to make more of the stuff? Even use it as part of a STEM session or get prospective students to make it on a school Open Evening… I think it would be pretty fun.
The ingredients are even simpler to buy if you have access to the school ordering system (at least for the iron oxide!) and who doesn’t have some PVA glue?
I think I’d want to try it out myself before I considered doing it at home with children — the iron oxide and breathing aspect makes me hesitant. I also prefer the idea of the slime over putty as think it would be more visual. Especially on an Open Evening in the Physics room!
Heatherton! This little collection of games from Wales is kind of addictive! There are three games that appear to be free to play – Archery, Race Car Testing and the Maize Maze.
The Archery game involves some speedy maths to earn arrows which you then get to use on targets where it’s all about the angle and force you apply. Apparently you can move up a level, but I’m not sure if I managed that!
The Race Car Testing game involves choosing different surfaces or different gradient of slope to then have a race car test. Each surface/gradient has to have 3 test runs before an everage is calculated (or you can turn off the calculations so you have to measure the stopping distance and average yourself). Some of the surfaces are normal standard ones – sandpaper, tin foil, glass – and then there’s jelly!
For the maize maze, there’s a whole bunch of information you can read before then answering questions on, well, maize. I didn’t read the info, but still got a handful of questions right and I guess this game will only be useful if you’re studying maize.
All three games have printable results and they don’t require logging in. Definitely something there for physics and maths.
Viscosity experiment for kids.
This would be awfully messy to do at home, in school or as STEM, but isn’t science supposed to be messy and fun?
In the blog, different home-found liquids were used to test their viscosity in a simple ramp race. They used oil, water, passata, corn syrup, treacle and ice cream sauce. I love those options! I might change passata for ketchup and try other table sauces, too, even possibly different brands of one table sauce. Just to stretch the STEM Club into thinking a bit harder! It’ll be just as messy as the syrup one we currently do (syrup at room temperature, from the fridge and warmed in boiling water), but maybe a little bit less sticky. Plus, table sauces come in squeezy bottles and are relatively cheap for all of the waste that will come with it!
Does Aspirin Help Plants Grow? | Education.com.
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 is a pretty nifty, colourful little collection of resources.
Resources are separated into different age ranges: 5-7, 7-11, 11-14, 14-16 and teachers with all of the ranges having different topics to select.
For example, using the teacher section, there are 3 drop down menus for age of student, theme and then topic. This is the same structure if you went on the 11-14 page, but far less colourful!
Scibermonkey itself is very colourful and fun looking, especially to entice those younger into having a look, but then all of the resources are links to elsewhere – games, animations, BBC Bitesize information, diagrams to label. They are all interesting and useful, but each resource could be from a different website that isn’t quite as fun and colourful as the Sciber Monkey site. It is very easily searchable by keywords though, which is always a good positive!
