BLOG OF SCIENCE EXPO

Every year i get excited for Science Expo.Ethan and I have done it together for 2 years.This year our topic for Grade 5 was energy.We decided to build a plastic house using recycable items like plastic bottles.We built five things  and  they were a eco wall, solar bulb, solar kettle, eco cooler and plants in a bottle.The reason we chose this is so we can not waste electricity and money on lights,aircons and other household supplies.
