Notes:

– The Coriolis effect describes how earths rotation steers wind and surface ocean currents

– Coriolis causes moving objects in the northern hemisphere to appear to be moving right

-Coriolis causes moving objects in the southern hemisphere to appear to be moving left

– Even though the object is actually moving straight, the earths rotation makes it look like its curved

– Earth rotates beneath freely moving objects like water and air. Compared with a spot on the planet, the freely moving objects appear to be moving

– Coriolis is an effect rather than a force because it is not forcing a motion, it’s just an appearance of a change of motion

Questions based on the video:

1. What is the Coriolis effect?

When an object in motion seems to be deflected from its corse as if a force is pulling it sideways

2. What is subject to the Coriolis effect?

The rotation

3. What is the direction of deflection in the Northern Hemisphere?

Right

4. What is the direction of deflection in the Southern Hemisphere?

Left

5. What happens if pilots do not correct for the Coriolis effect?

If they enter the northern hemisphere and keep going straight, they will look like they’re turning because the earth is rotating, so without curving, the pilots will not get to their destination because they are going in a straight line, but the earth is moving.

1. Does the volume of the solvent affect how much solute is needed to produce a

saturated solution (a solution in which no more solute will dissolve)?

Yes.

2. Present your results in a line graph. Are there any data points that do not fit the

pattern?

3. Study your data. Do you see a relationship between the mass of the solute and the

volume of solvent? Describe the relationship.

As the volume of solvent increases, so does the mass of the solute.

4. Solubility is the quantity of solute that will saturate 100ml of solvent at room

temperature. What mass of table salt would be needed to saturate100ml of water at

room temperature?

About 24- 40g because for 25mL, the amount it 6-10g so you can just multiply that by four.

5. You were given a thermometer for this activity. Explain how and why you used the

thermometer for this activity.

We weren’t given a thermometer.

6. Describe another investigation you would like to conduct that would further help you

understand the concept of solubility.

7. List 2 -3 questions that you have NOW after doing this investigation or that relate to something else we have done.

Multiplication and division are related because they are all a fact family. When you multiply two numbers together and get a product, you can do division by taking the product and divide it by one of the numbers that were multiplied to get the product, and the answer would be the other number multiplied to get the product.

For example:

3*4= 12

12/3= 4

12/4=3

1. Observation before dissection: Give a description of what you owl pellet looked like before you started to dissect it. What was its’ size, color, texture, etc….
   1.  It was pretty long and pretty wide, it was like a brownish blackish color, it was really hard on the outside but really soft and squishy on the inside. It had some fur in it and had
2. How many skulls were in your pellet? How about the number of animals in your pellet? Give the names of what you found. There were two skulls in my pellet, and there were two rodents in my pellet.

1. Give the names of the other types of bones you found in your pellet.

1. Explain what else you found in your pellet….feathers, fur, other things??

1. Did you find a complete skeleton? If you did not, give three reasons why you did not.

1. Describe the habitat where this owl lived.

1. If your owl forms one pellet each day, based on YOUR findings, how many animals would an owl eat in a week? in a month? in a year?

Darwinia 1B Focus Questions

1.According to the story, what food did the Toothpikta originally eat? What

adaptation did the Toothpikta use to capture this prey?

Toothpikta originally ate soft body insects. They used their long slender

mouthparts.

2.Describe how the environment on Darwinia changed over time. How did

the changing environment affect the Toothpikta’s food source? How did

the changing environment affect the Toothpikta?

Darwinia started having less rainfalls, which made the soft body insects dry up

and die. And without food, the Toothpikta species became extinct!

3.Over a long period of time, sometimes thousands of years, most living

organisms become extinct. Why? Use evidence from the story and the

game “Staying Alive” to answer this question.

Their prey could become extinct because of natural causes, which leads them

to no food. And the prey could become more biologically fit and overpopulate.

On a separate sheet of paper, draw a new Toothpikta, including adaptations

that will help it survive in the new environment of Darwinia. Label the picture

with descriptions of the adaptations, and their purposes.

Focus Questions for Round #2. When answering these questions, make sure to have topic sentences and

evidence. Don’t forget to check for spelling and grammar!

1. What does it mean for a species to be “Biologically Fit?”

Biologically fit means it can mate and reproduce. And it could survive and thrive.

Name:

Class:

2. In the first round of “Staying Alive” which predator was the most “Biologically Fit?” Use the data collected and your other observations

to support your answer.

Bladerunner. Because in trial 1 toothpickta got 1.1% Tweesarian got 4.166% And Blade Runner got 10.8% And it could easily catch

prey. And with its blade shaped mouth, it could get resources easiest.

3. The Prey were the beans in the first round of “Staying Alive” Which prey was the most biologically fit? Use the data collected and

your other observations to support your answer.

Whites Beans. Because the white beans got the lowest scores. And that means that it had enough of that species to reproduce, while

the others got eaten the most.

Focus Questions for “The Mythical Kingdom of Darwinia”,

Part IV

1.    Does the story tell us exactly what happened to the Tweesarians and Blade Runners in the Kingdom of Darwinia? Which species do you think you would find if you visited Darwinia today. Explain your thinking, and support with evidence.

 No. The spoon billed crackatows. Because they became really biologically fit because they had no predators, so they kept reproducing.

 Do you know any examples from the real world in which non-native species were released into the environment? What happened as a result? If you do not know of any examples, choose a living organism and imagine that it has been introduced into an area that it does not usually inhabit. What do you think might happen?

If an organism goes to a place it doesn’t belong, it could make the other species become extinct. If a gorilla ends up in northern Canada, it can take all the resources and leave the other organisms starving.

Scientists are very careful not to contaminate the Earth with samples of soil, air, etc. from space missions that may contain living organisms. Why should scientists be concerned? Support your answer with evidence from Darwinia.

Because, if a non-native species came to earth, it could kill the environment and economy. And they could reproduce and take all our food, and make the human race extinct.
