Bottle

Problem Plastic bottles are have been shown to be harmful in many ways. So, why do we still use them all the time? How are they harmful to us and the environment? What is a better material than plastic? Problem Statement What are the factors that are contributing to the plastic bottle problem? Variables Dependent Variable About 50 million plastic bottles are made in the US each year alone Only about 23 percent of them are recycled So about 38 billion plastic bottles are wasted each…

Would you want your child to be dehydrated during the school day? Taking water bottles out of the classrooms at school would prevent children having water nearby. If the children don’t drink enough water per day, this could leave to health issues. We need to keep water bottles in the classrooms to keep the children healthy, happy, and safe. Water bottles are a necessity for life. If our bodies do not consume enough water, we can potentially become dehydrated. Dehydration in children can…

Physics Fair – Bottle Rocket (Introduction, Materials and Method) Introduction A bottle rocket is composed of two elements, energy and fuel. The energy in the case of a bottle rocket is compressed air as it is pumped into a soda bottle, half filled with water by a bicycle pump. Compressed air is an excellent source of energy because it is very lightweight and can store a plentiful amount of energy, also it does not weigh down the rocket. Water is then used as the fuel for the rocket. Water is…

an old glass milk bottle, like Shatto, that had its lid screwed on tight and had a piece of paper inside. When I got the bottle out of the water I tried opening it to see what the note inside said. The lid was screwed on so tightly though, probably to keep out the water so the note would stay dry, that I had a difficult time of opening it. Sara came over and tried opening it with her muscles until her brain kicked in. There were lots of rocks nearby, we could just smash the bottle against one…

of the film is has to do with the water bottle industry. The film itself is basically split into two parts, half of the film talks about the water bottle industry and the other half talks about the effects that the water bottle industry has on the environment. The film starts off in a small town named Fryeburg, Maine. The people of the town talk about how the town used to be before “they” came in. The “they” in this case being one of the biggest water bottle manufactures, Nestle. The people of…

use chemical reactions to lift off into space. Using baking soda and vinegar we can simulate a rocket taking off because when mixed together, a chemical reaction occurs. By changing the amounts of the chemicals we can determine which will allow the bottle rocket to go farther. Chemical Reaction Vinegar is an acetic acid. When an acetic acid and baking soda (sodium bicarbonate) are mixed together, three new chemicals are formed, Water (H2O), carbon dioxide (co2), and sodium acetate (C2H3Na02).…

Building bottle rockets can be a fun and learning experience, as many students at UCAS found out. There were many things to test, and many interesting aspects of the rocket. Three main features of the “Mission to Mars” are how to construct the rocket, rocket performance, and physics of the rocket. When these items are viewed, it is evident that students can see the effects of physics in real life problems. And by doing so become more intelligent as teenagers want to learn more, and have fun…

Cutting Back on Plastic Water Bottles Introduction According to the CRI (Container Recycling Institute), each day in the U.S. more than 60 million water bottles are thrown away, about 22 billion per year. The ultimate problem is the misuse of the water bottles after they are consumed. About 80% of plastics end up in landfills or incinerators, and as seen many are littered and end up on the streets or in public parks. Another main issue is the cost of water bottles, not necessarily the cost…

Stevenson uses suspense not only to entice the reader, but to make sure the reader is aware of what's going on while raising questions of what will happen next. To clarify, an example of suspense being used in the story is in paragraph…

hole in the top of your parachute, it will greatly reduce the amount of swing making a more stable landing. Of course, the bigger the hole, the less effective the parachute is so you don’t want to make it too big. Our rocket is made out of a 2-liter bottle with the bottom half of another…
