A Breakthrough Study!

           In order to help many paralyzed people, scientists developed something amazing! It's a chip built in to your mind and it controls robotic hands to get things. The experiments happened at Duke Medical Center. For Cathy Hutchinson, a paralyzed woman, this was remarkable. Before, she had to rely on a helper to get things out of reach. Now, she can be much more independent. This is truly an amazing help to people in need and it is the start of much more.

Current Events: James Cameron Plunges Into Ocean

           You may know James Cameron as the famous director, working on films such as "Titanic", but over the weekend he did something even more amazing! James Cameron is the first in fifty two years to plunge that deep into the ocean! James plunged nearly seven miles into the Western Pacific! His submarine touched the dark, mysterious ocean floor. He arrived to the surface on Sunday (March 24th) evening. James Cameron broke the record for deepest solo dive!

       My opinion about this record breaking dive is on the edge. It sounds like a lot of fun, but only if you have proper training like James. He trained for seven years! At the same time, it is very dangerous. It is the deepest place in the world. Not to mention many have died attempting what he did. lastly, the bottom of the ocean is dark and it would take forever to get back up! Overall, I wouldn't be as brave as James and plunge seven miles into the ocean!

Separating Mixture

1. Take out the plastic bug using the scooper.
2. Using your hands, take out the two toothpicks.
3. Use the magnet to remove iron pieces.
4. Pour out the beans.
5. Take funnel and beaker and pour the water down the funnel into the beaker.
6. Leave the sand in the cup.
7. Place beaker on hot plate until the water evaporates.
8. Pour the remaining substance on to the coffee filter.
9. The remaining particles are salt.
10. Clean up!

Frog Dissection

           In science class, we dissected a frog. From this lab, I have learned alot. It helped me understand both the human and frog bodies. We found the heart, kidneys, lungs, the stomach, and many more organs. We even got to open the mouth and see the tounge. The dissection was very fun and educational.

             The dissection helped me understand the organs and their functions. For example, I now know that the kidneys are filters for the body. The lungs take in oxygen and release carbon dioxide. Also, the heart pumps blood throughout the body. I also got to see where the organs are all placed in a frog bodies. The kidneys are by the back of the frog. The lungs and the heart are right by each other. Overall the dissection experience was helped me understand the human and frog body.

Digestion Lab

                   On Monday and Tuesday, our class did a digestion lab. We took egg whites, acid, enzymes, and water and made examples of digestion. In beaker A the enzymes alone didnt do any major changes. In B, which was water and enzyme, the enzymes mixed into the water. Beaker C had only acid. The acid didn't really do anything either. Lastly, in D, which was acid and enzymes, the egg whites started to slowly breakdown. All in all, this lab let me understand the digestion system more clearly.
