Testing the pH

It has been a week of investigations in both science and maths.

During science, we tested various solutions today with two indicators; litmus paper then pH paper. We also discussed the merits and limitations of each. Later in the week we looked at Universal Indicator and pH probes and discussed the merits of those by comparison. We have also been taking a closer look at the pH scale and what it means. 
In maths, we have been looking at the relationship between shapes and we made some rectangular circles, using pie charts and glue.
