Introduction: Have you ever tried to make a bottle rocket using only baking soda and vinegar? This is known in science a chemical change. The science behind this is you mix to two compounds, baking soda and vinegar. When they mix it is called reactivity and it creates a gas in the bottle. So how much baking soda added with 10mL of vinegar would it take to shoot the cap the farthest? I thought 15mL of baking soda would shoot the cap farther than other amounts because it would have more baking soda to react with the vinegar. Thus, leading to a bigger and better reaction. The independent variable was how much baking soda I added and the dependent variable is how far it shoots.
Materials:
• Baking soda
• Film canister
• Vinegar
• Paper towel …show more content…
The first launch ended up going a total of 400cm and went far because it was pointed strait and not up. The second launch on trial A, went 367cm, making a big popping sound and hit the ceiling reducing how far it would have gone. My final launch on trial A went a total of 514cm but it took about 6 seconds for the lid to blow off. Overall, my average was 307cm. Trial B was a little different because I added 5mL of baking soda. The first launch went 359cm but there was bad aiming on my part and I hit the ceiling. Then, on the next launch I only got 350cm.This was due to a little too much baking soda causing the whole paper towel to launch out. But, on the last launch I got a total of 476cm, which which sent the cap past the table and onto the counter. This time my average was 395cm. On trial C, my first launch, the cap didn’t go very far having adding 5 more mL of baking soda. The cap only went 341cm. Now you had to operate quickly so the reaction would work. On the next launch I got 287cm but this test hit the counter and launched within a second or two. Finally, our last launch, and I got 500cm and I notice the measurements were bouncing unpredictably. My average for trial C was

Force and History of World

...Forces and Motion For Students of Baldwin Wallace College Spring Semester 2011 Monday – Wednesday 10:00 – 11:15 am Room 139 Wilker Faculty Richard Heckathorn The materials for this course were organized and edited by Richard Heckathorn using materials from a program called Operation Physics and includes materials developed by him. The original OPERATION PHYSICS activity sequence to improve physics teaching and learning in upper elementary and middle schools was funded by the National Science Foundation. Original Material Copyright 1992 by American Institute of Physics Materials edited and photoduplicated with permission. FORCES & MOTION INTRODUCTION WORKSHOP LEADER’S TOPIC INFORMATION INTRODUCTION TO FORCES & MOTION An understanding of force and motion is fundamental to the study of almost all other physics-related topics. Yet it is a topic often overlooked or only cursorily introduced in elementary and middle school science, even though it is a topic typically identified for inclusion in the curriculum for these grades. A primary reason for this is that many teachers do not feel comfortable about their own understanding of the topic. Consequently, this may be the most needed of all of the OPERATION PHYSICS workshops. This workshop leader’s notebook is divided into two parts: PART ONE Motion Part One begins by introducing participants to the concepts of space and time....

Raspberry Ketone

...Part I Essay For ages we all have craved the body of an Adonis/ Aphrodite`s, some say that this are just genes passed on, some say that you can only get it with intense training at least 4 times a week. But the 21 century, the century of speed, no one has time to lose countless hours in the gym so we started looking for some help. We tried different chemicals but in the end we realized that the answer was still in Mother Nature. And so Raspberry Ketone was discovered. A raspberry ketone is generally described as the aromatic element of a raspberry that one first recognizes when in close proximity of a raspberry. While this ketone clearly affects the scent associated with a raspberry, this is not the only thing that can be affected by a raspberry ketone, though. More specifically, raspberry ketones are now being associated with not only weight loss and fat burning, but they are also being through to aid in reducing the likelihood of having liver cancer and cell damage. Raspberry Ketone represents a new element on the market that helps in the fight for a perfect body, sustaining weight loss and fat burning. Just recently been proven to give individuals who regularly consume this product the upper hand in the battle against weight again and fat retention. This represents part of the sales pitch that the company offers, but what does science say? There is some proof for this product but nothing is certain and there were no human studies recorded...

The Impact of Not Having the Arts in Elementary Schools

...The Impact of Not Having The Arts in Elementary Schools A Review of the Literature Detra B. Bynum Capella University Author Note This paper was prepared for Education 5200, taught by Leonard Snyder Abstract My literature review will show a connection between cognition, social and emotional development and the arts. Some students in schools where the arts are an integral part of the academic program tend to do better in school than those students where that is not the case. It will also show why it is so important to have art and music classes in the elementary schools. It will also show how the teachers can help develop cognitive skills by using the arts in their lesson plan. They can intertwine the creative arts curriculum with other subject such as reading; math and science to develop better studying, concentration and listening skills. Studies will show that children need expressionism with the other subjects to complete their learning process. The review will show why the arts need to be implemented back in the curriculum of elementary schools. We have the opinions of others, that younger school children should be required to study math language; science and history are those people who think it may not be necessary to learn art and music. Contrary to those people's viewpoint, my strong opinion regarding that statement is that younger school children have to be required to study art and music. This literature review may point...
