Cabbage juice is an acid-base indicator (a chemical that tells you something about other chemicals). If it turns a pinkish color, the substance was an acid. If it turns a greenish color it base. If it stays about the same, it is neutral. Also acids and bases can react to one another...
Fall is here and apples are everywhere! We have been having fun with apple books and crafts and decided to do an apple science experiment too. The kids love acid and base reactions, but this time instead of combining them we observed to see what effects they would have on apples. ...
In this experiment, you have an acid (cranberry and lemon juice) and a base (baking soda) and when combined make a gas called carbon dioxide which produces the eruption you can see. Learn more about acids and bases here. The carbon dioxide escapes the mixture in the form of bubbles. You...
When an acid and a base mix, they form carbon dioxide, a gas. Learn more about acids and bases. The eggshell breaks down, leaving a soft, bendable, squeeze-able, rubber egg. Does it bounce? Kids can gently squeeze the egg and bounce the egg. However, be prepared for the eggs to bu...

Monitoring the pH range of a laboratory reaction or a process is very important. It is important to keep the pH almost constant even when addition of acids or bases takes place. One can easily know if a solution is an acid or a base using a visual indicator. Indicators are organic dye ...
It should be as similar to the proposed study as possible, using similar subjects, the same setting, and the same techniques of data collection and analysis. prospective study an epidemiologic study in which the groups of individuals (cohorts) are selected on the bases of factors that are to ...
My teacher told me that there needs to be purpose to the experiment, something that I'm trying to find out. (I asked about dipping leaves in acid and noting the result and he said no because there doesn't seem to be a purpose..) ...
