On 27/4/2017, we had an incursion with a geologist called Steph and we learned about natural disasters. Some of the disasters we were focusing on included cyclones, floods, bushfires, earthquakes and a little on tsunamis. Steph showed us three experiments to show how some of these work.
The first experiment we did was about a volcano eruption. We had baking soda in a bottle and some vinegar in a smaller one. We poured the vinegar into the bottle of baking soda. The mixture shot up as if the volcano had erupted.
The second activity we did was about earthquakes. Steph had built three types of models showing how fault lines move apart, push together or slide which demonstrated how earthquakes occur. We built little houses on the models to see if they could survive the different types of earthquakes. In the end, only one group’s house survived.
The third and final activity we did was about floods. We had a container with some pebbles, sponges and plastic animals. We also had a valley (Two plastic bottles cut in half) and two bottles full of water. We poured the smaller bottle into the valley to see if it would flood but it didn’t. Then we poured the bigger bottle into the valley and it flooded. The goal was to keep your animals alive.
It was a great day over all. Year 5 learned so many new things about natural disasters. It was definitely worthwhile and a great experience.
