In groups, we were given a bundle of K'nex pieces and Ms Druhan set us a challenge to construct a piece that would cross a river. We discussed what we could make. Some groups made boats, other groups made rafts and some made bridges. We really enjoyed constructing our pieces. Take a look at them!

We did an EGGSperiment! We had to guess which egg was raw and which egg was boiled. We looked at them, we shook them, we felt them, we shone a torch on them and we put them in water but we couldn't figure out which one was which. We then remembered that the raw egg was liquid inside and the boiled egg was solid inside. So we spun them and stopped and one of the eggs kept spinning. The egg was raw kept spinning as it was liquid inside. Ms Druhan cracked the egg that we thought was raw to see if we were right! We were!
Ms Druhan asked us if we could make the boiled egg stand up on its own. We used a jumper firstly. We thought about sports, like rugby and what they use to make the ball stand up. We piled up some salt and we placed the egg standing up on the salt. We tried to see how much salt was needed to make the egg stand up. We started to blow away the salt using a straw so that we could aim it carefully. Finally, we discovered that the egg would stand with only a few grains of salt. Second Class made 2D shapes using our bodies and lollipop sticks. Have a look and try to guess the shape!
