Put your finger on the 7. The strongest acid has a pH near 0. Most fruits are acids. It is normal that most fruits are acids, it keeps them from spoiling as quick. 14 is the strongest alkaline.
Drain cleaner is almost that strong.
The closer the pH is the 7 the less strong the alkaline. Sometimes it may help to compare temperature to pH using cold, hot and comfortable. The lower the number on the thermometer the colder, higher the hotter, but comfortable is always the same. That's why its important to have scientists like you measure it. By sliding their finger straight down most students can discover if there is an organism whose pH range is within the number you called 2.
