Tetromina

On Friday, a scientist named Mr. K-O came to our class and discussed what he does as a scientist, and conservation. He talked about how us kids in this generation can help for a better Earth for the next generation. He also answered our questions about what he loves most about nature. In my title,you can see that it says, "Tetromina." If you should guess why and get it right on you first try, you are sheer genius. Tetromina is one of the many things scientists play around with to figure stuff out, like why there are predators and why there are prey, and why things are different between animals and humans. These are things that people want to ask, and scientists want to answer. As soon as possible I hope. While Mr. K-O was visiting, he showed us some interesting news he found in his science magazines while reading on the plane. He compared the Earth to a bank. We only have so much, and when we run out, we have no more. Just like when we run out of food. What do we do? We go to the grocery store. What happens when the grocery store is out of food? We go to a different grocery store. What happends when all of the grocery stores run out of food? We starve. Never take more than you need people! Save a life. Some ways you can help the Earth are:

1. If you see trash on the ground, pick it up. We don't need that there.
2. If you aren't using the light or the water, turn it off.
3. For you adults, if you go to the same work, carpool instead of driving your own car. It causes less polution in the air.
4. Recycle your old water bottles, paper, boxes, etc. , etc.
5. Dispose of batteries properly. We don't need the Earth having electrical shocks everyday, and we don't need the Earth having less and less animals.
6. Don't let oil and debris go into the drains. This can back up the drains.
7. Leave animals in their natural habitat. There's no need to keep it as a pet.
