In science class on 19th November, there was an experiment in reversible and non-reversible changes.
My group was with Prilly, Reggy, and Jasper.
The materials that we need is sugar, a spoon, a candle, butter, candle wax, a spoonful of flour, a beaker
half-filled with vinegar, a teaspoon of baking soda.

Reversible and Non-Reversible Changes
If a material goes through reversible changes, it can change back to the original form.
If a material goes through non-reversible changes, it cannot change back to the original form.
Examples of Reversible Changes :
A chocolate ; Freezes and Melts
Examples of Non-Reversible Changes
Egg
That's all. Thanks
