Science Fun!!!!!!
In my science class we had an interesting experiment. We are learning about the Earth. Our teacher wanted us to learn more about the mantel. She explained to us that the mantel is a solid but acts as a liquid. Many of us were confused. How could a solid be a liquid? Well we conducted this experiment. First you will need the following materials: half a cup of cornstarch, half a cup of water, a spoon, and two beakers. Next pour the water into the cornstarch. Take the spoon and mix the water and cornstarch together. You will realize that the mixture will become harder and harder to stir. After mixing take your hand and take a good amount of the mixture. If you let it be the mixture will melt in your hand and start to drip down. But, if you touch it, it will suddenly become hard. This is a good example of what happens in the mantel. Plasticity is the term that explains this experiment. The mantel has this specific property. As a result the crust can float on the mantel. I learned a lot about the Earth and this experiment was fun!!!

October Sky
In my class we watched an amazing movie known as "October Sky". It is about a young boy known as Homer Hickam who watches one night as the Soviet satellite Sputnik zoomed across the night sky in his hometown of Coalwood, Virginia. He becomes inspired by the Sputnik and soon begins to build rockets with his friends Quentin Wilson, O'Dell Carroll, and Roy Lee. But, Homer's father dislikes the rocket building because he hopes for Homer to become a coal mine worker. Determined to win the science fair Homer ignores his father's remarks and soon the "Rocket Boys" start to build rockets. When they begin to launch rockets at their launch site at Cape Coalwood they were soon accused of starting a forest fire. Homer soon had to stop building and launching rockets which depressed him deeply. Homer's father soon gets into a coal mine accident and Homer takes over because Jim, Homer's brother received a college scholarship. Homer soon proves that they did not cause the forest fire after his father gets better. The fire was caused by a flare that was shot from a nearby airport. Soon the "Rocket Boys" enter the science fair which they won. When Homer also wins the nationals he is overwhelmed by college scholarships. When he arrives back to town he is a hero. He shows the medal to his teacher who supported him throughout the entire event, Ms. Riley, who was diagnosed with cancer. They then launch their final rocket which Homer's dad attended and launched. Homer and the other boys graduated from college. Homer's father died due to Black Lung Disease and Ms. Riley died due to cancer. This movie had many connections to Earth Science. For example, Homer's father worked in the coal mines which are located underground. Homer Hickam's story proves that you can accomplish anything if you put your mind to it.

Bugs Found with Heat Sensors!!!!
Scientists believe that the western conifer-seed bug, Leptoglossus occidentalis, has infrared radiation that comes out of it. The bugs navigate this thermoscape using infrared receptors to locate the seed-bearing cones they feed on. Scientists at the Simon Fraser University in Burnaby, British Columbia, and several colleagues discovered that the bugs were often attracted to warm objects in poeple homes. To find out more, the team measured the teamperature from different pine trees. Cones were as many as 27 degrees Fahrenheit warmer then needles and emitted stronger infrared radiation. Then, theseted the ability of the bugs by offering them a strong or weak infrared source. The insects overwhelmingly chose the strong radiation. Scientists believe that some plants use radiation to advertise pollinators to come to them. I believe that this discovery is important because if we learn more about infrared the more we can use it.
