Evolution Lesson Review Questions

1. Explain the difference between artificial selection and natural selection.
Artifical selection is when the breed is not valied which means that the breed of the species is unexpected. Natural selection is when the breed comes from the ancesster of the breed. It is as if the breed from the accesstors is a gene.
2. How does common ancestry between two species support evolution?
It’s like genes. It tells the species what it’ goning to look like, where it lives, and how it lives. Also since evolution is a way that things in life change overtime are formed it helps the breed decide what the new specie is going to turn out to be.
3. Explain the principle of overproduction. Give an example.
Overprouction is when the specie has the breed that is wasn’t suppose to have. It can’t survive in its habitate because it wasn’t made they way they were suppose to.
4. How are variation and adaptations related to natural selection? Give an example.
Well, since natural selection is how the specie is unexpected, it variations doesn’t tell you what will happen next.
5. How might the mass extinction of dinosaurs enable many new species of mammals to develop?
Once the dinosaurs die out they compost into the ground and turn into soil. Worms then live in the soil and then the birds eat the worms who then gets eaten by other mammals and so on.
6. How would natural selection have led to the development of giraffes with long necks as opposed to giraffes with short necks?
Because they gene like breed would cause the breed to dis-function and change the way the giraffe came out.
7. The beaks of hummingbirds are adapted to fit into long, thin flowers. Hummingbirds can feed on the nectar inside the flower. Write an explanation for this adaptation that Lamarck might have proposed. Then write an explanation for this adaptation based on Darwin’s ideas. Use the term natural selection in your answer.
Lamarck discovered evolution. He thought that if a giraffe stretched his neck long enough it would get longer and be able to get leafs off of high trees. He thought off springs passed on. Darwin disagreed. Like Darwin, he discovered Natural selection and Artificial selection. He discovered how different species behavior depends on the habitat they live in.

Evolution vocab

Evolution-They ways species change over time.
Darwin discovered that evolution was how animals lived.
Artificial Selection-When a specie has a gene from an ans ancestor from over hundred years.
Natural Selection- When a specie take act of their natural habitat
Isolation- Is the population by barries that lead to specation.

Evolution summary

Many would say the earth has been around for 3.8 billions years. Actually it has been around for more then that. It has been around for 4.5 billion years. That is a long time! Now, that makes me think how have thing changed over time. Well, one thing that i know that has changed are cell phones. The first cell phone was a wooden box like figure that you can use to connect with someone who is on the other line. You could use it like any other phone but you can’t carry it around. That takes me to the phones we have now. We have what is called a cell phone. Or what teens call today cells. We can send text messages, do our work, and even surf the web on these phones. They are also now very portable. All this change is called “Evolution”. Evolution is a change in different species. One example is Charles Darwin and his discovery. Darwin was twenty years old when he went on the Begal ship and sailed to the Galapagos Island in 1831. In the Galapagos Island there are 18 Islands in it. Darwin discovered that there are different species of animals and plants in those islands. He found out that it depends on the species habitat that they are created to look a certain way. He also discovered Natural Selection and Artificial Selection. He published his book in 1859.

Log 3

Name: Gum Glore

Date: Valentine’s Day

Witness: Ravi Patel

Notes: This week I started my project. I looked up how to make gum base and then when im done I will try to make different tastes myself.

Things You’ll Need:

  • Chicle
  • Vegetable Oil
  • Bees Wax
  • Powdered Sugar
  • Old Pan
  • Spoon
  • Oven
  • Waxed Paper


Step 1: Put six ounces of chicle in a shallow pan and heat to 350 degrees (F) in an oven and at the same time warm 1 ounce of beeswax in a separate pan. Warm both pans for approximately 10 minutes

Step 2: Remove the warmed chicle from oven and immediately make an indentation in the chicle with the spoon, and, into this indentation, add the ounce of warmed beeswax, plus one teaspoon of vegetable oil.

Step 3: Mix thoroughly with the spoon. Work quickly before the chicle becomes too stiff to stir. This is your gum base

Step 4: Rewarm the gum base in your pan to 350 degrees (F) for ten minutes. Remove from oven, and immediately stir two teaspoons of powdered sugar into the softened base.


Step 5
:
Rewarm yet again in the oven at 350 degrees (F) for ten minutes. Remove from oven and immediately remove from pan and place gum base on a sheet of waxed paper. Flatten to 1/4 inch with the back of your spoon, and use a knife that has been warmed by holding under running hot water to cut the gum base into 1/2 squares. Dust with confectioner’s sugar and allow to cool. Makes approximately 10 – 12 pieces of gum.

Witnessed by: Augie

Notes: Again I was making sure that I have all my stuff. I am going to start the Gum base this Wednesday and try to saute the gum in veggie juice. I will also try to find ways to flavor a plain piece of gum. After I will have Augie try them.

Matter Vocab

Matter- Anything that has mass and volume.

Mass- is the amount of matter in an object.

Weight- is how much something is pulled by gravity. W=ma

Volume- is the amount of space something takes up.

Density- is a specific property of matter that is heated its mass divided by the volume. D=M/V
