Her project showed that the lionfish can survive in nearly fresh water. The results blew away professional ecologists. The invasive species has no predators on the Florida coast, so if they were to migrate upstream in rivers, they could pose a threat to the ecosystem.”
Charlie and his friends are going outside to investigate some awesome sports stuff! In this episode they figure out the secret to throwing a curveball, a crazy swooping baseball pitch. Turns out it’s all about physics! Spin the ball the right way and boom, you have a major league caliber pitch … it’s that easy.
Volcano eruption from the International Space Station
