Science Week Next Week - Take It Easy


Guest

Recommended Posts

Pressure is on me -science week coming up, take it one step at a time.......

 

Boil some red cabbage, keep the water (eat the cabbage). Use the water in portions.

Let children add vinegar (or lemon juice) - an acid - and watch the red cabbage water change colour. Let them add sodium bicarbonate (bicarb=bicarbonate of soda or baking powder) - an alkali. To and fro with these. It's magic!

 

Make volcanoes: a pile of bicarb (you can mix in some powdered food colouring), and some vinegar or lemon juice and it "erupts".

 

Put some bicarb and vinegar in a bottle, put a balloon over the neck (I suggest you blow it up by mouth fisrt then use it after it has deflated). Then watch the gas from the reaction inflate the balloon. Let it go.......

 

In a saucer of milk (about 0.5cm deep) add some spots of food colour, evenly spaced. Put a spot of washing up liquid in the middle, then just watch.... amazing.

 

Burn candles inside jars and let children put the lids on to make them go out.

 

Separate ink colours on blotting paper (let me know if you don't know how to do this).

 

Make some quick set jellies (they set before you can say abracadra)

 

I didn't know where to put this.

 

Diane.
