This was a helpful article, recycling can be a much better substitute over throwing things on the ground or on the earth. Recycling can also preserve materials and allow for them to be used again. It's much better than just throwing away something that is re-usable. This also wasn't too hard of a guide to follow, as nearly anyone can do it. I also do agree with putting more emphasis on recycling.

This was another good article on how to make a recycling bin. It was much more detailed however, and is a more "professional" looking recycling bin. I could see myself using this method to make a recycling bin as it doesn't involve using too much materials. It doesn't take long to do, which is a plus since it is best to save time when creating things.

This article was short and simple when explaining how to create a recycling bin. It doesn't involve using many materials or supplies to make the recycling bin. All it requires you is to find a storage container and then label it according to how a recycling bin would be. This isn't as in depth as other articles, but it does get the job done. It also makes the task very simple.

I found this one as easy the guide by doityourself.com. It is very simple and inexpensive to do. Finding a wooden crate is also cheap and can be actually be obtained for free. However, the only drawback I find to the recycling bin in this article is that it is mainly for newspapers. It would be best to have an all purpose recycling bin so you're not limited on what you can put in it. This does save a lot of paper though.

Making a wooden recycling bin does take much more time than making one by different materials. It involves much time cutting and combining pieces when you easily use a different material, (such as plastic) to make one. However, making a wooden recycle bin would be sturdy. It would also be strong enough to support anything put inside of it.
For this activity, I created two designs that both worked from beginning to end. The ball was even able to make it through both loops on the first design. I created the double hills at the beginning to gain a good amount of speed.
For this activity I had to design a roller coaster that would be safe and fun according to the choices available. It took many tries, but I got it after thinking through on how it could work.
At the start of a roller coaster, potential energy builds up, gravity then takes over. After this happens, kinetic energy sets off during the ride. I also noticed that there is much more speed gained after coming down from a loop or from a downward ramp.The gravitational force also got lower as the ride went higher.

All roller coasters use physics to work. The starting point uses a mechanism to pull up the cart, and the rest of the roller coaster uses kinetic energy to move to the cart throughout. Most roller coasters do not even use engines or motors to move the coaster at all.
TLC How Roller Coasters Work
As shown at the beginning of the flash video, the coaster has the most potential energy at the first hill. This gives it a lot of energy to move downwards at a fast speed. At the next point, the energy is used and kinetic energy is increased, as the coaster is in motion. At the next hill, it again builds potential energy, then a shift between potential energy and kinetic energy continues throughout the end of the roller coaster.
For level one, it was actually simple, but it did take some time to figure out the correct points. I made the first point go downwards to give the car more speed, because as it goes down further, it'll have more speed when coming up. The speed that it gained from the first slope, allowed it to move past the first hill and reach the end. The slope was made just low enough so it wouldn't hurt the passenger.
On level two, it was pretty much the same as level one, except this time there was an extra point. This time, I used two downward slopes to gain speed when it was decreased by going upwards. This allowed the car to pass through every point. At the end, I added more of a straight edge so that the car could wouldn't stop from going to far up or have an accident by going downwards.
Level 3 took me a couple of runs to adjust the roller coaster. Many times I would run into a point where I would have good momentum and speed, but the passenger would be injured in the process. I had to make the gaps just low enough to get speed and make sure the passenger would be safe from harm.
Finally, level 4 was not too much of a hassle to finish. It wasn't as hard as the previous levels, as it was much easier to build speed with the longer length of the roller coaster. I simply used a few gaps and started with a downward slide at the beginning to gain a good amount of speed to finish. It was also easy to keep the passenger safe.
~ I'd say there is, even before High School and Middle School, I've really been interested in technology. I've wanted to build & create new things for people. One of the main things I want to do is to be an Architect, which will require knowledge of Engineering.
~ I also have an interest in automobiles, not just the look of course, but how the vehicle is designed and the work that goes into it. All of the things under the hood that power it.
