Did you use the websites provided to you for this activity? Did they help? Explain.

No, I didn’t. I looked up keywords of the summary or title that the Cornell notes gave me.

How do you think you can use your Cornell notes in the future?

Maybe if I want to be a historian or if I have a research project in the future.

What are 3 new things you learned from researching the colonies in this way? (This one you can just bullet point if you’d like)

  • Debtors Prison
  • What a Puritan is
  • What an indenture is

Why did we do this activity?

We researched the 3 British colonies Jamestown, Plymouth, and Roanoke.

How did you research for this activity?

I used my google search operators.

What were the biggest challenges you encountered during this activity?

Finding information.

How did you overcome your challenges?

I asked for help and used different search operators.

Final Scientific Explanation on Sea Lamprey and Trout

Did the Sea Lamprey Cause a Decline in the Trout Population?

 

The trout population is decreasing because of the invasion of the Sea Lamprey. According to the lesson, 5 fishermen say that the trout they catch is either dead or have massive holes in their sides. They also catch less and less trout every day. When he fished at his spot this year, he caught twice as many trout last year. The trout has a small hole only the size of a quarter but it is very deep. This means that ever since the Sea lamprey got here, the trout population got halved. When the Sea Lamprey came to the Great lakes the trout population decreased greatly. From 1950 to 1970 the trout population decreased and the Sea Lamprey increased. The Sea Lamprey is an invasive species so they came and killed all of the trout and increased their population to 300,000. This means that the trout are heavily outnumbered. Which means that there is probably more than one sea lamprey for every trout. In food webs, the Sea Lamprey have no predators and have a ton of prey. This is important because the sea lampreys population is way more than the trouts and might even be so low that they could go extinct in a few years. This shows that ever since the Lamprey got here the trout population went down due to a combined effort from Lamprey and other trout predators.

 

It was discovered that the Sea Lamprey’s eggs have a big reason for being dangerous, they can carry 60,000  to 100,000 eggs which means they reproduce extremely fast. Every 1 female that dies giving birth means about 50,000 Sea Lamprey hatch every time a female lays eggs. This means that the sea lamprey has way more of their species than the trout. Which means that the Sea lamprey has so many more of its species the Lamprey kill more trout faster.

 

Another big factor is the way the Sea Lamprey swim. The sea lamprey is an S-Swimmer which means they use their whole body to move. The trout are half-body swimmers. Which means they are slower and its movements are more sluggish than the sea lamprey. This means that the trout have little chance of getting away with all of their blood.

What materials did you choose for your build and why?

We used all of the materials that were on the packet.

Here is a picture of my plan:

Here is a picture of my first attempt at the building process:

it was our plan except without a top.

While you test:

 

What are you noticing?

We have to work everything. There is nothing she can do by herself.

What things are working?

The tower is standing up and sturdy.

What things are not working?

The rope is coming off and the slime is hard as a rock.

How will you tweak this? Make this better? (Be specific and detailed!)

I would make something else that isn’t made out of the slime.

Do you need any new materials? If so, WHY?

Yes, I need any materials that would make the other thing because I don’t want to make anything out of the slime.

What is your new plan? My new plan is to make a tower out of wood, make Rapunzel out of tin foil, braid our rope for Rapunzel to make thicker, make a slide out of our old tower.

Why will this new design work better than your first attempt? What is your evidence?

It is more sturdy and it is more realistic.
