A few weeks ago on Thursday a lady named Estah from Vector came to our school to talk about being sustainable with energy. She talked to us about the different types of energy for example, mechanical energy which moves objects from place to place. There are also electrical, chemical and radiant energy. She talked to us about how we can save energy and made some suggestions such as to take shorter showers, turn of light switches, etc.
Estah also showed us a wooden plane that had no batteries in it and the top moved when there was light shining on it. That was called radiant energy and mechanical energy. There was also a car that had no batteries in it and the same thing happened, it moved when there was light shining on it.
