This Year In Science - 10th grade intro video

This Week In Science #13

a) If we were to leave these spider habitat tanks sealed but removed all of the plants a few things would happen. The first thing would be that the spiders would die. The spider would die because they wouldn't have a source of oxygen and eventually all the carbon dioxide the spider is releasing would kill it because it wouldn't be able to breath.

This Week In Science #12

This week in science we learned and did many interesting things. We finally put our spider into our environment, we named ours Cudi. We made a little book where we put some definitions and we will be writing future observations about our spider and our spider's environment. It was really cool to feed the spider because we were able to see how he captured his pray.

We also learned things like what an energy pyramid is and the type of relationships animals have. We learned that at the bottom of an energy pyramid its always the sun and it is basically the opposite than a food chain because the arrow goes out from the thing that is being consumed showing that, that thing is giving energy to its consumer. We learned about the relationships some animals had with each other like, a mutualism relationship like a clownfish and an anemone, where they both benefit each other . A commensalism relationship like a barnacle's and a whales where one benefits and the other one doesn't get effected. And lastly a parasitism relationship like an alligator's and a leaches where one benefits and the other gets hurt from it.
