On Friday the 20th of November we invited parents to come in to school for a science investigation on pendulums. We split into groups and decided which variable we were going to use to do our experiment.Some people decided to change the weight of the pendulum and some people changed the length of the string.
We planned our experiment and discussed what our outcome might be.
We repeated our experiment three to five times for each variable to get an average. We timed how long ten swings took.
We found that the weight of the pendulum didn't make any difference to the speed of the pendulum.
We found that the shorter the string, the faster the pendulum swung.
Thank you to all the parents who came in to help.
