5MB - Working Scientifically
In Science this half term, our focus has been on the National Curriculum's objectives of working scientifically. This has given us the scope to do some really fun experiments with the children, while also teaching them key skills like taking readings, doing a fair test, hypothesising an outcome.
The rainbow experiment, shown below, was finding the acids and alkalis in our household liquids, using homemade red cabbage indicator. We talked about what acids and alkali's were and then what they could expect to see happen to the red cabbage water when they were mixed. We then all did the experiments as a class, measuring out the same amount of liquid to create a fair test, and all logged our results.
The children had a lot of fun working scientifically and loved the range of colours from our household items like sprite, vinegar for our chips, mouthwash, salt, bicarbonate of soda and regular tap water.
