Content

I used the connections ( teachers, peers, texts, and internet) a lot. We did a lot of research so the internet was a really big source. The two things that actually helped the most was having our teacher available for any questions and being able to talk to my peers if i had any problems. Thanks to that I was able to understand the content to apply it to my work.

Product & Presentation

In the projects our class did, me and my partner did cite our sources but not in MLA/APA format. I was not aware that we did have to cite them in that matter. We did revise and edit our work because we wanted our work to be good quality. The way we adressed our audience was formal yet we managed to use some humor in it.

Individual Work Skills

Throughout the semester  I didn't really need our teacher to keep telling us step by step what to do. I had a pretty good idea of what I had to do in our project. I did ask quesions just not as many as I would have wanted.

Collaboration Skills

I did become a leader when I had to. I respected the ideas an opinions of others. I wasn't always focused and engaged but I managed to keep myself on track. I helped others understand what was going on when they needed it.

Project Management Skills

I did horrible on meeting dead lines on some assignments. I did set goals and met some of them. I could work on mannaging time better. I can create plans effectivly and solve problems.

I could work on managing time and meeting ALL my deadlines.

Tue, 31 Jan 2012 08:43:00 -0800 Experiment Design #2 http://wshsarelit.posterous.com/experiment-design-2 http://wshsarelit.posterous.com/experiment-design-2

Q: How does the position we hold the javelin affect how far it is thrown?

 

Hypothesis: If we change the position we hold the javelin then the distance will change.

 

Materials:

 

  • Javelin
  • Wind measuring tool
  • Measuring tape
  • Video Camera

Procedure:

  1. Find a large thick grassy area
  2. Set up video camera at an appropriate distance
  3. Measure wind and record
  4. Set position of hand that is needed ready to be thrown
  5. Throw Javelin
  6. Measure with measuring tape from the spot thrown to the nearest area on the javelin  and record
  7. Repeat steps 4-7 with every hand position. Do three trials

Thu, 26 Jan 2012 08:21:07 -0800 Experiment Design http://wshsarelit.posterous.com/experiment-design http://wshsarelit.posterous.com/experiment-design

Q: How does the angle you throw the javelin affect the distance it lands?

Hypothesis: If we change the angle of the javelin then the distance will change.

Materials:

  • Javelin
  • Hylen
  • Track spikes

Procedure:

  • Before we start we're going to record how Hylen feels, wheather she's sore or got a lot more buffer than she was. We're also going to record the weather conditions and the condition the grass is in.
  • The angles we're going to try are 45 degree, 65 degree, and a 35 degree. We're going to use a trick we learned in geometry to make sure we have the right angle.
  • The distance is going to be measured using a measuring tape. We're going to measure in feet and inches.
  • We're going to take video and take notes on the throw.
  • In the end we're going to make posters and present our findings.

Tue, 17 Jan 2012 08:52:00 -0800 Physics of Sports Project Proposal http://wshsarelit.posterous.com/physics-of-sports-project-proposal http://wshsarelit.posterous.com/physics-of-sports-project-proposal

* What is your experimental question?

How does the angle the javelin is thrown affect the distance it lands?


* Why do you want to answer this question?

We want to help Hylen improve.

 
* What is your hypothesis?

If the javelin is thrown at a 45 degree angle it will go the furthest.


* What are your main variables (manipulated, responding, controlled)?

Wind, speed, the position of the hand.

Thu, 03 Nov 2011 08:49:00 -0700 Bridge Prototype Designs http://wshsarelit.posterous.com/bridge-prototype-designs http://wshsarelit.posterous.com/bridge-prototype-designs

DESIGN 1:

This is my very first design. I didn't think about it i just started designing it and my bridge looks like it would be sturdy and would hold up.

Bridge_design1

DESIGN 2:

My second design was based on my first one. Since my first one had  a lot of weight in the middle so I made some changes. I took off some weight from the middle and added an arch at the bottom for support

Bridge_design_2

DESIGN 3:

I decided to make this bridge on a smaller scale just to see how it worked out and if it worked as well as the bigger bridges I designed before.

Bridge_design_3

 

DESIGN 4:

With this design I decided to make a small replica of my second bridge design.

Bridge_design_4

 

DESIGN 5 & 6:

With these two designs I was just experimenting and trying something different that i thought would work. At first the designs weren't working so I changed and improved them and they worked perfectly.

Mon, 24 Oct 2011 19:50:00 -0700 WEBQUEST-BRIDGE DESIGN http://wshsarelit.posterous.com/webquest-bridge-design http://wshsarelit.posterous.com/webquest-bridge-design

FORCES:

1a. Compression-A force that squishes something together.

1b Tension-A force that stretches something.

1c. Buckling-An affliciton developed by people moving in and out.

1d. Shear-A force that causes material to slide past another in opposite direction.

1e. Torsion-An action that twists a material.

LOADS

2. Dead Load- Anything attached to the structure.

Live Load- Things that move in or on the structure.

Settlement Load- When soil beneath structure settles uneven.

Thermal Load- When the structure expands and shrinks with the temperature.

Earthquake Load- When the ground beneath a structure moves back and forth.

Wind Load- When wind blows on the structure.

Dynamic Load- When beams vibrate too much.

3. Live Load- too much weight breaks the structure but when renforced by a thinck beam it is less likely to bend and break.

Settlement Load- the structure sinks when settlement is uneven but when you put concrete pillars underneath it becomes stable.

Thermal Load- too much heat makes the structure break but if you put roller joints it gives the columns and beams freedom to expand and contrast.

Earthquake Load: moves the structure too much and the structure ends up breaking but when you renforce with shear balls it stiffens.

Wind Load- the structure couldn't withstand the strong winds and toppled over but if you add diagnal braces it stabilized th structure.

Dynamic Load- the structure vibrates too much so you add a thick beam and it becomes less likely to bend.

SHAPES

4. The triangle is the strongest shape because it is the most stable and rigid shape used in contrustions these days.
