We’ve been busy making borax free slime at present and thought it will be enjoyable to attempt three totally different slime recipes then create a enjoyable science investigation to see which slime was the perfect!
No Borax Slime Recipes
Cornflour Slime
Merely add somewhat water to cornflour and also you get a slippy slime that may be scrunched up right into a strong ball in your fingers. Unclench your fingers and it flows like a liquid once more. Cornflour gloop ( often known as oobleck ) is a non-Newtonian fluid which implies it doesn’t move like liquids normally do.
Any such slime is tremendous simple to make, feels beautiful and silky and for those who depart it to dry is simple to comb away afterwards.
Cornflour Chia Seed Slime
Soak a handful of chia seeds in water for just a few hours after which add cornflour and somewhat water. This makes a stunning thick slime, which flows superbly by way of little fingers.
Fybogel Slime
It sounds a bit odd, however fybogel makes an excellent slime. Add a sachet to water and boil on the hob or in a microwave, as soon as boiled depart to chill, try to be left with a sticky, gloopy slime!
How will you check slime?
We thought very rigorously about check our slimes, and devised three checks.
The Stretch Check
This concerned attempting to stretch the slime between our fingers.
Winner – Fybogel Slime
Keep in mind to make use of the identical quantity of every slime.
The Viscosity Check
We arrange a viscosity race to research which slime was essentially the most viscous. Viscous liquids are thick and move extra slowly than much less viscous liquids.
Winner – Cornflour Slime
Keep in mind to make use of the identical quantity of every slime and time how lengthy every takes to move between the identical two factors.
The Splat Check
For the splat check we picked up a handful of slime and threw it at a chunk of cardboard. We determined the perfect slime could be the one which made the most important splat.
Winner – Fybogel Slime
Keep in mind to make use of the identical quantity of every slime, throw from the identical distance and with the identical pressure.
For extra enjoyable slime recipes to check, attempt among the nice no borax slime recipes over on Pink Ted Artwork. We are able to’t wait to see how they do in our splat check!
We’ve additionally bought a creepy Halloween slime to attempt.
Slime – Studying Factors
This can be a nice exercise for beginning to suppose scientifically. For every check focus on make it honest, for instance standing the identical distance from the splat board and throwing the identical quantity of slime.
Attempt asking youngsters to foretell which slime would be the finest in every check primarily based on their present data.
Extra Slime Actions
Are you able to make a greater slime? Attempt including chia seeds to the Fybogel or utilizing totally different quantities of water.
Hyperlinks with English
Are you able to write a narrative that includes slime?
Are you able to write a set of directions so another person can observe your recipe?
Hyperlinks with Maths
Are you able to report the time taken for the slime to move between the 2 factors on the viscosity board and plot the information on a graph?
Should you favored this exercise you would possibly like our walking on oobleck activity too!
