1. Given the challenge and the performance of your car on Test Drive #1, what change(s) did you make for Test Drive #2?
We made the rubber band bigger so it could have more energy and then it would go further.
2. What differences did you predict these changes would make in your car’s performance? What makes you think this?
I thought that it would make it go further, we thought that because we saw our friend’s build and saw that they had a large rubber band so we thought we would give it a shot.
3. Think about the variables such as the size of the spool, weight of the washer or tension of the rubber band. How might these affect how far or how fast your car will go?
The weight would affect the car because it would weigh down the car and slow it down. It would slow down because the rubber band would have to generate more elastic energy.
4. What worked better the second time?
It definitely went further because we shot it right and we had a better build.
5. What still is not quite working?
We still don’t shoot it right on the 1st try.
6. What questions do I have?
None
7. What might I try next?
Lessen the weight of the racer so that it can go further.
8. Explain the energy transfer that is taking place in the racer.
When we pull back the rubber band it is generating elastic energy and when we let go of the band, it converts that elastic energy into kinetic energy sending the racer flying.

1. What do you like about your initial design?
I like that it is very creative.

2. What has been challenging about the initial design?
We didn’t have enough time to do the original idea.

3. How well did your racer perform in the first race? Did it go far? Fast?
It didn’t perform well because I shot it wrong with the rubber band.

4. How will you modify your design for the second race? What variables do you feel will affect how far and fast the racer goes? Why?
I will find the way to shoot my car without it sometimes going the wrong way because it can go further than that it’s just that I didn’t shoot it right.

5. What have been your strengths and challenges during the design process?
Strengths was that we got the design done on the day we started building it. My challenge was trying to shoot the car right because 1 out 3 times I would actually shoot it right.

This is my final product for the 1st part of this challenge.

This is the original sketch of my car.

6. What questions do you have?
None.

Do you think the temperature of the room affects the time it takes an odor to get to your nose? Explain your answer. Provide two pieces of scientific reasoning to explain why.

It doesn’t because temperature doesn’t have a current and cannot move things on its own.

The Sea Lamprey is causing a decline in the Trout population.  

From one of the texts; “Fisherman’s Journal” that we read we learned that the Sea Lamprey invaded the Trout’s territory forcing them into a different area that they aren’t used to. In new territory, there is less food and/or potential predators and then Sea Lamprey will not be the only species invading a food web. Even if there is Trout still living in their natural area the Sea Lamprey not only eat Trout but they also eat a lot of smaller fish which trout also eat. Causing them to get eaten and starve thus causing them to die.

In class, we read that the Sea Lamprey have 60-100 thousand eggs that all contain more Sea Lamprey and then there will be lots of baby Sea Lamprey to go around. Since the Sea Lamprey has no natural predators in the Great Lakes they can mate freely making them eat a lot more food. Making them plenty and then eating a lot more trout than when they came because there’s more Sea Lamprey

In the video Silent Predators, we saw how much damage the Sea Lamprey can do to a trout. Their sharp teeth cut into the inside of the skin and eat all of their internal organs. This could cause, fatal blood leaking and just straight up death. This kills all trout being eaten by the Sea Lamprey making the trout population die out.

• What is the value of dissecting?

I don’t feel like there is any value in dissecting because 1st, it’s their body and their privacy 2nd, we are killing animals just to discover what’s already been discovered.

• How did the dissection help you understand what is happening between the sea lamprey and the trout?

The dissection showed me nothing because I already knew that the sea lamprey was biting the heck out of fish.

• How did you feel about dissection? If you enjoyed the process, why did you enjoy it? If you did not enjoy it, what was difficult about it?

I don’t like it because we are needlessly killing animals for us learning something that can be learned in ways that don’t harm animals it was difficult looking at the fish knowing that it was killed for me to tamper with its body.

What do you think invasive species means?

It means if a species comes and takes over a different species territory

What does it mean to invade something?

To come and come in unannounced on territory that isn’t yours

Can animals invade?

Yes, they can come into my house, be scary and force us to leave because no one wants to get eaten.

What about plants?

Yes because there are lots of plants (weeds) that spread into places that no one wants them (my backyard)

How might invasive species affect other organisms in their environment?

It could force them to move to a different area/biome where they can’t really live as well as in the area they were born in.

Today in science we tested a bean seed and a potato for starch to answer the question, “Do plants contain the food that organisms need?” Below, is my scientific explanation that explains what we learned and discovered from our lab today.

Claim:
Potato’s have starch in them

Evidence:
It turned black when we put iodine in it

Reasoning:

It turned black showing that the idodine found starch

This was one of our tests.                                   This is our final project.

Ari and I went through a lot of trial and error. 1st we had a cool design, but we needed more potential energy than we had. The 1st model fell apart so we had to rebuild it. Both of the pictures above show the final design.

Summary of my project:

Prior Knowledge:

I have played bloxels many times before. A lot last year but a little this year. I found it very fun.

Planning:
We decided to make a wolf chasing a rabbit. The player plays as the rabbit. The player has to go through the jungle to escape the wolf. The wolf chasing you is imaginary… it is just adding the effect of the story why you are running. Og didn’t get what I ment so I had to explain the game to him.
