If you were asked to imagine a scientist, what image would come to your mind? The common idea that most kids have of a scientist is a man wearing a white lab coat with messy hair, big glasses, and several glass cups of mysterious colorful liquids giving off clouds of smoke. As for adults, the majority view scientists as strange people who spend 100 hours a week slaving away in a lonely laboratory. However, the reality is quite different.
Recently I’ve had a chance to take part in a scientific experience far from my laboratory in Costa Rica. It supports a huge amount of wildlife due to its geographical placement between North and South America. It is home to more than 500,000 species, which represents nearly 4% of the total species worldwide!
First we worked alongside conservationists to preserve wildlife at a leatherback turtle(棱皮龟) rescue center. We helped the volunteers preserve turtle populations by removing rubbish from the shoreline to create a safe environment for turtle eggs to come out. After that we stayed at Mount Arenal where we studied seismic activity relating to earth-quakes. During our stay at Arenal, we rode over the mountainous areas and took a long walk through the rainforest. After reaching the top, we went down and through waterfalls to the beautiful valley below. On the last day we got a hands-on introduction to Rocket Science where we learned about new rocket technology that will be used on the international space station.
During my Costa Rica experience, I know that being a scientist doesn’t mean working in a lab all day and night. A scientist may be one who loves learning and getting a better understanding of the world from helping preserve wildlife, learning about earthquakes or inventing rockets. I think that schools should really stress that science is so much more than wearing a lab coat and mixing chemicals. Kids need to be aware of the excitement and adventures science can bring！
