Experiment

Dear group members,

Please remember to take a video of the procedures for your experiment and to give an explanation for each procedure.

And also take a photograph of the materials that you all used for your experiment.

There are 4 experiments:
1) using vinegar to light up a bulb
2) using potatoes to operate a digital watch
3) using water and paper clips to operate a sound chip
4) using mechanical energy to light up a bulb
