At Science works, we learnt so much new vocabulary! First we saw the Lighting show. It was amazing! We were introduced to the large Tesla coil which creates thousands of volts of electricity. We were safe because we were protected by the large black farrida cage. We learnt that electrical charges are in everything. Volunteers came up to try different experiments. Balloons can help move electrical charges around. This is called static electricity. We learnt about the positive and negative symbols. A positive and negative charge=attract. But two of the same charges like a positive and a positive=repell. Then it was time to play with the Vandergraft. It looks like a big metal ball. A volunteer stood next to it with a handful of confetti in her palm and her arm stretched out. The static electricity flowed through her to make the confetti fly away. Her hair also stood up! To repell this charge all she did was jump down so that her feet could break the charges flow.
We learnt about the rules of electricity. Circuits help to make electricity. If there is a gap in a circuit then it won’t light up. Conductors let electricity flow through them. Insulators do not allow electricity to flow through them. Wood and plastic are insulators and metal is a conductor. Then we needed to predict what a lightning bolt would strike. We learnt that you will be safe in a car and an airplane if it hits you. We were shown a strategy if we were outside in dangerous weather. We were told not to lie on the ground because lightning can travel along the ground after it’s hit. The safest pose is to bend down, stand on one leg and put your hands on your head. Standing under a tree is also dangerous because lightning strikes tall objects and then can travel through your body.
We had such a fun day!
