Cork to a Window

Today in class we had to do a project where we measure amounts of vinegar and baking soda. Our group did not touch the window but we got a few centimeters away only if we shot it higher. We were given a box a of baking soda and a beaker of vinegar. Our tries varied, we just couldn't get the amounts right. We were told to find the exact amount of vinegar and baking soda that will shoot our cork from one side of the room to another. We have another day to do this but it will still be difficult. More then one try is available so there will be many chances to get this correct. I think that this lab can help our problem solving and measurement skills. It is also a really fun project, we learn and have fun. Just what kids need.

Extra Credit Response!

"In Science the credit goes to the man who convinces the world, not to the man to whom the idea first occurred." Said by Sir William Osler (1849-1919) Canadian physician.

I think that this quote means that even if you thought of something and didn't share it you should not get credit. I think this because when you get an idea that you think can change the world or even help the world you should share it because your idea isn't going to share itself. The minute you have an amazing idea, or an idea you think is amazing you should share it with people (be sure to use the copy right button :p.) Be sure to share your great ideas with the world instead of letting somebody else take all the credit when they share it with the world. When a man or woman does share it with the world, the world won't believe if you thought of the idea, they'll give all the credit to the person who shared it.

Plasticity Lab

Today in science class we were assigned a lab called the Plasticity Lab. When we sat at our lab tables we saw corn starch mixed with water with blue food coloring. I had to evaluate whether or not this mixture was a solid or a liquid. This experiment's solution was very hard to determine whether or it was a solid or a liquid because at first when we rolled it up between our hands the corn starch turned into a solid. After we pulled our hand away and left the corn starch on just one hand it became a liquid. I finally came to a conclusion that the mixture is both solid and liquid.

Flamingo's specialities

Flamingo's are known for its wonderful unique look but have you ever wondered why most flamingos only stand on one foot? This beautiful bird has caused Matthew Anderson, a psychologist at Saint Joseph's University in Philadelphia to question many aspects. One question he had, but later on recieved an answer is, "why do flamingos only stand on one foot?" He found out that they do this because with one leg they keep their body heat up and they don't strain both leg muscles. If a predator came near a flamingo, they would have the energy to run because both legs aren't stiff. Matthew Anderson when to the Philadelphia Zoo and observed flamingos too see what their movements are and how they stand and rest. When flamingos are in cooler weather, they stand on one leg, when it is warmer they stand on two legs. Flamingos usually spend most of their time in the water, water tends to take most of your body heat away, this is why flamingos conserve their body head by lifting one leg and keeping it near their body so they can be warmer. Personally, I think that flamingos are unique animals and that they stand with only one leg because they like to keep their balance and practice balancing. Also, I believe that what Matthew Anderson did was good because most people don't observe flamingos of all animals, so Mr. Anderson decided to make a change and research weird questions about flamingos like, "why do flamingos only stand on one leg?"

Hello Mrs. R

yooooo(:

Corn Starch

The mixture was very soft and gooey. Also, when the gushy substance was in your hands it was hard like a solid, when you lifted one hand upwards the substance became liquid. When you are rolling the mixture in your hand it becomes a solid and turns hard. When you life one hand up it becomes softer and softer and turns into a liquid. When I pushed my finger inside quickly the substance felt soft and then hard. When my finger went inside slowly the substance felt hard. Ways corn starch and water combined compares to Earth's mantle because of the movement. A solid that acts like a liquid is the athensopshere, a soft layer,which is molten lava, that is similar to the corn starch because the liquid acted as the solid. The layer is a harder layer right under the crust is the lithosphere, the corn starch is turned into solid under the palm of your hands.

October Sky Response Blog

A few ways the movie October Sky relates to Earth Science is that underground the mines are formed. Another example is how the rocket was stuck in space and could not come back. Also, Homer's father tried to help a man because something happened in the mines under ground, but he failed, therefore causing Earth's substance to fall on the poor man. Lastly, Homer won the science fair and is going to the nationals, this relates to Earth Science because with all the rockets shooting upwards can cause some reaction in the sky and/or ground.

Physical Science also appears in this movie various times. A few ways are that when the rocket finally worked that gave him a higher chance of being in the science fair at his local high school. That relates to physical science because physics moves the rocket. Also, during science class for Homer, he poured chemicals in the sink and a girl threw a flame into the sink, this caused a chemical reaction caused by physics and made a large flame. The last sign of physical science I found in the movie is when the coal fell on the man and unfortunately died. Physics caused the coal in the mine to fall upon the man's head.

How math is used in this movie is when Homer and his friends are trying to figure out what is needed to build a rocket. Another way is when Homer and his friends are trying to figure out where to launch the rocket. Lastly, when Homer tries to figure out where his last rocket landed to prove himself not guilty of causing a forest fire.

Character Ed was also used in this movie. Six ways they were used are :

• Homer wanted to build a rocket and he is eager to build it.
• Homer's dad is rude and mean to Homer because of his dream.
• Homer and his friends are cooperating.
• Homer & friends didn't want to get in trouble once again so they burned down the rocket house.
• Homer has to provide money and work in the mines so his family can keep his house, so Homer gives up his dream for the time and works in the mines.

• Homer's dad can get back to work and Homer can begin to work on teaching everybody about rockets.

These show how Homer showed Character ed in the movie October Sky.
