Elementary school students give short speeches on popular science
The following is an example of a short popular science speech suitable for primary school students: Magical Science Dear teachers and students, Hello everyone! Today, I want to share with you some interesting scientific knowledge. Did you know? Science is everywhere around us. Just like the sun that we see every day, it is a huge star. It is very far away from us, but it brings us light and heat. Why? It turned out that there was a reaction called nuclear fusion going on inside the sun. It was like countless small bombs exploding inside, releasing a huge amount of energy. And the little marbles we play with, when they roll or collide on the ground, they also hide scientific principles. The rolling speed of the marble and the angle of collision would affect its final trajectory. This involved the knowledge of mechanics in physics. Science is amazing. It's in our lives, waiting for us to discover it. Let's stay curious and explore more mysteries of science! Thank you, everyone! maybe Entering the World of Science The students: Hello everyone! I want to talk about the science around me. Did everyone blow bubbles? The transparent and colorful bubbles were very fun. Why are bubbles round? This was due to the effect of surface tension. The molecules on the surface of the liquid were like a group of small hands. They all wanted to pull the bubble to the smallest surface area, and a circle was the shape with the smallest surface area under the same volume. The candy we eat has science too. The hard candy will become smaller and softer after a while in the mouth. This is because the temperature and saliva in our mouth slowly melt the candy. Science is in our lives. As long as we observe carefully, we can find many interesting things. Thank you! Read more exciting novels for free
