Section 1 Assessment p. 179


Section 1 Assessment p. 179          Mohamed Amarouch

1.a. Darwin’s important descriptive observation included the diversity of living things, the remains of ancient organisms, and the characteristics of organisms on the Galapagos Islands.
1b.  The tortoises on a island had dome-shaped shells. Those on another island had saddle shells. The iguanas on the Galapagos Islands had big claws that allowed them to grip slippery rocks, where they fed on seaweed. The iguanas on the mainland had smaller claws. Smaller claws allowed the mainland iguanas to climb trees, where they ate leaves.
1.c. Adaptation is a trait that helps an organism survive and reproduce. Claws of Galapagos help the iguanas to hold on to slippery rocks, that is their adaptation. The mainland iguanas had small claws, which helped them climb trees to eat leaves, which is their adaptation.
2a.The seaweed that is in the Galapagos island forced the iguanas to climb the slippery rocks so that’s how they have big claws.
2b. Selective breeding supported Darwin’s hypothesis by the observation that he saw from the farmers and also what he did to the pigeons. Darwin had bred pigeons with large, fan-shaped tails.
3a. Variation is any difference between individuals of the same species. Natural selection is the process by which individuals that are better adapted to their environment are more likely to survive and reproduce than other members of the same species
3b. After a long period of time, natural selection can lead to change. Helpful variation may gradually accumulate in a species, while unfavorable ones may disappear.
3c. All the members of species would have the same traits. Natural selection would not occur because all individuals would have an equal chance of surviving and reproducing.

Solar Energy vs. Coal Essay


Essay                                              Mohamed Amarouch


Solar Energy vs. Coal

These two forms of energy produce the same energy, but every one has different process and effects. One is renewable (solar energy) and the other is non-renewable (coal), this gives them advantages and disadvantages. Solar energy and Coal may be different but they produce the same kind of energy.

Solar energy is fitter for the environment, more then 10,000 homes in the United States use solar energy. Photovoltaic systems are solar systems that produce electricity token from sunlight. Solar energy is only useful when the sun is shining, but, pollution can be a disadvantage for solar panels; it can decrease ability of photovoltaic systems. We use solar energy every minute of the day because of the sun. It is more used than any other fossil fuel on the earth. To get solar panels, it costs $215 for only one but to build solar power station, it costs a lot. It is really expensive. A bad thing about solar energy is that it doesn’t give out energy if the sun is not present, so if there is a cold country who really needs heat, solar energy will not help.

Coal is one of the three most important fossil fuels. Coal must be dried before being burned successfully.There are about 861,000 coal supplies in the world. The countries that produce the most coal in the world are China and the USA.
Coal takes a million years to create and therefore it belongs to non-renewable energy sources. Coal is one of the three most important fossil fuels. Coal must be dried before being burned successfully.
Different types of coal have different uses. Steam coal is mainly used in power generation. Cooking coal is used for steel production. Solar energy works when sunlight photons hit a solar panel, bumping electrons creating an electrical current. Coal Energy produces a lot of pollution.


Between these two resources Coal is better form solar energy. It can be used in nighttime and it gives more energy then Solar gives. Even if Coal pollutes our planet it doesn't make that much of a difference if we still use it today. People think coal is old school as a energy source but in fact it is the most used energy source in the world. One of the biggest advantages of coal is that it inexpensive. Coal is a solid so that makes it easier and safer to transport compared to other energy sources.

Science Fair

Science Fair Question: Which detergents will effect color and texture of a jean?

Hypothesis: I think that the detergent Ariel will effect the jeans the most because it has the reputation of having strong effects on jeans.

Introduction: My science Fair is going to be focused on how detergents effect color and texture of a jean. My cause will be detergents and my effect will be the washing machine. I will compare the texture and color of my jean with a sample. Then I could see which jeans, color and texture changed by comparing it to the sample of jean.

The Silurian Period





Warm up:

The process of making a brochure needed a lot of focus and creativity.
Before I could start righting my information I needed to find the exact space (were I could put my information.) Next I had to use my creativity by choosing colors that blend in with my time period. My most important learning by creating this brochure was to blend my creativity with my information for me that was my biggest challenge.

CAN PENGUINS FLY?


My critical thinking: Yes, I think that these penguins can fly , by using speed, energy and strength by running faster and by bending their spine downwards, the penguins use the energy and strength from the constant speed it is using. Here are reasons penguins can't fly, their wings do not contain the primary flights (that helps the wings support the animals body). Also penguins can't fly because their wings are adapted to swimming. The birds wings are conneceted to their body that gives them the ability to support the speed and weight.The bird that is the most related to penguins and that has the ability to fly is the puffin bird ,the puffin birds have almost the same wings as penguins, but puffin wings are connected to the body (with supports the body while trying to fly.)



REAL ANSWER: NO PENGUINS CAN NOT FLY THE BBC WAS AN APRIL FOOLS DAY SPECIAL VIDEO.
