This is how you can make some awesome marbleized looking Easter Eggs quickly and easily, without a lot of mess and spending a lot of money. Here’s what
Source: How to Make Shaving Cream Easter Egg Dye
I found a link on pinterest the other day that I just thought “Ooh, eggs and shaving foam”, pinning it for another day. Then I thought, let’s actually look at the method! It looks so, so simple. We’ve been planning on trying to make natural dyes (raspberries, coffee, etc) to paint some eggs here in school, but this method is much simpler and easier to put together.
In fact, I’ve put the ingredients on my shopping list to try at home!
Corrosion Demos This page has an amazing demonstration for corrosion, incredibly visual and fast to show in a classroom setting. This is a very good way to show corrosion actively happening rather than the usual nails in large conical flasks (which does look impressive over time, but not on the short term). Showing corrosion with nails in a flask also tends to ruin some of the glassware so can be pretty wasteful, petri dishes are supposed to be disposable! The link also includes the student sheet and slides for teaching with.
I can’t wait to try this one!
Super Glue Fingerprint Fuming.
This is the instructable page of all 8 steps showing how to use superglue to capture fingerprints with very simple, everyday equipment. I especially like the computer editing aspect at the end, the 8th step, and wonder how creative someone could be to incorporate this into more of a STEAM project than STEM.
Let me know if you have any arty fingerprints you’ve done yourself!
Burning a ping pong ball experiment – YouTube.
We showed this to our teachers. They found it amazing. This very simple demonstration would be perfect as a starter and also very visual on an Open Evening.
E is for Explore!: Red Bull and Milk Reaction.
What happens when you add Red Bull to milk in a 1:1 ratio?
What about vinegar and milk in the same ratio?
Change the type of milk from whole, to semi, to skimmed!
Why does any of this happen?
This simple, quick and clean demonstration is perfect for an introduction to States of Matter, to get brains thinking on an Open Evening or as a mini experiment for a STEM session.
Definitely one to try out! And easily performed and explained at home.
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?
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!
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!
Lammas Science – YouTube.
I’ve just been sent the link to this YouTube page and… Oh… My… God. I once spent an entire summer recording all of our VHS tapes onto the computer so that we had a digital copy. It took forever and although I didn’t actively watch them, I had to keep the sound on so I could catch the end of each episode. From the looks of this YouTube account, I needn’t have bothered!
If you look under Lammas Science playlists, you get collections of videos divided into different KS4 units (B2, C4, etc), there are Bitesize collections, other BBC show colelctions (Wonders of, for example) and broader topics (like forensics, pyrotechnics).
Easily an important site to bookmark, and view whenever needed. The fact that videos are labelled with relevant titles, especially linking them to specific KS4 units is what is most helpful!
Fun Absorbing Experiment for kids.
I found this through pinterest, simply by the image of three sugar cubes and it got me to wondering… Could this be used to measure a rate? Depending on what the tallest tower is that can be built without the bottom cube collapsing, could you make a stack in a coloured water and time when the colour reaches the end/beginning of a new cube? If you could get to 5, would that be enough points for a graph?
