In this demonstration, students will get a better understanding of what a geyser is and what makes it function the way it does. I was worried about trying this at the high school earth science level because it is a bit elementary, but the science is sound, and it works. Materials needed are:
In this biology video, students will grasp a better understanding of how cells divide through mitosis and meiosis, but the emphasis is on how through mitosis and meiosis, the daughter cells will either contain the same number of chromosomes or contain half the amount of chromsomes.
In this video, students will gain a better understanding of biomagnification and how primary consumers are affected by chemicals that humans put out that then have a chance at affecting animals above them in the food chain. There is an emphasis on how biomagnification affected the reproduction rate of bald eagles so this is a great science video to show when teaching some environmental science.
