In science we have been learning about acids and alkaline by conducting experiments using litmus paper and the ph scale.
Acids range from PH 1-6 and shows up as red, orange and yellow on the ph scale. Lemon is an example of an acid and can be corrosive. Alkalines range from 7-14 and show up as 8-14 on the ph scale. Toothpaste is an alkaline which we use to neutralise the acid in food we have eaten such as fruit.
We created posters to display our learning . I really enjoyed conducting the experiments and predicting what type of substances are acids or alkalines. Thomas S
