Chemistry at home - year 8

Post by RosalieL »

Hi everyone!

Has anyone got suggestions for year 8 chemical reactions they can do at home?

So far I have come up with:
Vinegar and milk
Bicarb and vinegar
Making pancakes/pikelets (to observe the creation of gas on heating)
Making honeycomb (under adult supervision! - again rapid release of gas when the bicarb is added)

We were planning to do coke and mentos later in the term as a demo… so I’m leaving that off the list for now.
Thanks in advance!

There's an invisible ink that's easy to make for an at home experiment.

Hi
dont forget sea shells they collect and Acid( coke) or vinegar or just use chalk or talcam powder
simple rust experiments or get to take photos on there essential walks of evidence of rust.
chicken bones or eggs in vinegar to show a change in the shell and bone
Melting butter in a saucepan and don't forget chocolate. to name a few
we have a video we've directed our kids to watch on u tube called Kitchen chemical changes gives a few everyday examples.
but most of all have fun with it

How about Whizz Fizz

0.5 teaspoons citric acid
4 teaspoons icing sugar
6 teaspoons jelly crystals (if you are vegetarian, please use extra icing sugar instead)
0.5 teaspoons baking soda
Small Ziploc bag

White flowers and food dye. A bit boring and maybe a little young for Grade 8. I did a celery stick with lots of leaves on the top a few weeks back, splitting it in half to the middle. Gently place each side in a different colour carefully so as not to snap off. Half in blue and half in red. The resulting leaves on top after a week were amazing.

Not really chem reactions I guess. flower indicators. bi carb and vinegar for the acid and base, boil the different flowers and use the coloured liquid.
pop corn for change of state.
Use daffs with blue food dye for the transpiration prac.
bi carb and vinegar into a balloon to collect gas.
Lots of surface tension home pracs.
