M & M Research Paper

The subject of Chemistry is one that deals heavily with a comprehension of the natural world and the individual details that make up an entire system. I was introduced to this course my sophomore year as I took on Honors Chemistry. As a student who grasps material best with hands on projects, this class fueled my excitement to be able to understand a complex subject using planned out lab procedures. From titrations to calculating the amount of copper in a solution, Chemistry gave me an opportunity to bring my own speculations into a class rather than being told directly what is occurring in a scientific process. The fascination of this class is what directed me to take AP Chemistry my senior year of high school. Even with the difficulty of

The 3 hypotheses created by the students, which are as follows, were put to the test during this lab. If an egg is submerged in distilled water, then the egg will expand in size. If an egg is submerged in corn syrup, then the egg will shrivel. If an egg is submerged in a salt solution, then the egg will shrivel. The hypothesis concerning the egg submerged in distilled water, was supported. The egg grew by 2.5 cm and weighed 12.5 grams more than it did in the beginning. The hypothesis concerning the egg being submerged in the corn syrup was also supported.The egg shrunk down to a significant size, the egg ended up being 22.42 grams lighter and a cm smaller than it’s original measurements. The last hypothesis, the one using salt water, was refuted. The students said the egg would shrink, like the corn syrup, when in reality it grew like the distilled water egg, in the end it had 13.19 extra grams and 2 cm that weren't present in the beginning.

Students will be able to describe how matter changed and explain why it changed. (Evaluation: Students were required to form a hypothesis of what would happen when a given liquid were to stay outside all day long in the winter cold and state what happened to the molecules to change the liquid into a solid. Based on what you know, how would you explain why the liquid changed into a solid?)

Hold up items from the box and have the children identify them with you. Give two contrasting objects to children and have them identify which is heavier. Ask them to predict the results of the experiment.

My project is about how much salt it will take for objects to float. In my project I will explain why certain objects float while others sink. I took three different objects with different amount of density and put them each in ten cups of water. I then put in teaspoons of water and recorded whether or not the objects floated until all the

In the lab, it was found that the properties of water are present when put into certain conditions. Within the experiments, properties of cohesion, adhesion, heat capacity, and hydrogen bonding presented themselves throughout the experiments. For instance, when water was mixed with oil in a test tube because the oil would not mix with the water because it is

The purpose of this experiment is to determine the identity of an unknown solid by measuring its solubility. Solubility is the concentration of a saturated solution. A saturated solution is one that has completely dissolved in water. Another way to define solubility is the maximum mass of solid that can dissolve in 100ml of water at a given temperature. In addition, solubility is a characteristic property, and its units are grams per 100 ml of water. Some key terms to know relating to solubility are the solute and the solvent. The solute is the substance that is being dissolved, while the solvent is the substance that is doing the dissolving. In our experiment, the unknown solid is the solute and the water is the solvent.

-Informing future students and parents about our grade 12 senior chemistry course by demonstrating labs and the chemistry behind them.

Introduction: Osmosis is the diffusion of water through a selectively permeable membrane. Due to the difference in concentration gradient, particles that are dissolved can go from high concentration to low concentration through a semipermeable membrane. The purpose of the investigation was to observe the effects vinegar, corn syrup, and water has on the mass of an egg. For the vinegar my hypothesis was, if the egg is placed in vinegar , then the shell will dissolve. For the corn syrup my hypothesis was, if the egg is placed in corn syrup, then the egg will form a new shell. For the tap water my hypothesis was, if the egg is placed in tap water, then the egg will stay the same.

Overall, I would definitely see myself using this activity and lesson in my science classroom when teaching fourth to sixth graders about chemical reactions and the indicator of color change. I believe that it is very important for educators to show how different concepts and subjects can come together to create something such as colors, like chemistry and art have done. Art is a subject that is often cut in schools because of low funding, so this is a perfect opportunity to bring art back into the classroom can connect it with science in a STEAM

    We were testing the solubility of the chocolate syrup brands while being stirred in whole milk. Our purpose is to see which of the major brands of syrup is most soluble and for what reason. This is important to our daily lives because it makes us aware of what types of materials we are ingesting and this applies to our experiment by seeing which of the ingredients take longer to dissolve. Information known is all brands are known to dissolve in milk but they all use different ingredients and they will cause a difference in the time it takes to dissolve. New information that will be gained from this experiment is which ingredients inside chocolate syrup will take the longest to dissolve, from the type of sugars in it to the syrups. We expected the Nesquik to dissolve the fastest because it did not contain any high fructose corn syrup while the other brand of syrup did. Also we observed from the syrups that nesquik was very thin, while the others were very thick and slow in behaviour. Our hypothesis is that the Nesquik will disintegrate the fastest in the milk because it lacks High Fructose Corn Syrup.

The purpose of this experiment is to see how the functions of an egg relate to a animal cell and also see the effects of the different solutions that we use on the egg during the experiment. I felt like what will happen to cell when it is placed in sugar and is placed in water is that is going to cause the cell to experience diffusion and the altering of the shape of it’s cell membrane. The way we conducted this experiment was using a shell-less egg and putting it through this process of taking it’s mass before and after each process it had to go through. Such as the shell-less egg had to sit in the vinegar for 30 minutes and after it sat for 30 minutes we had to take the mass. We saw that after doing this that the egg

Mrs. S’s goal for her students was to be able to identify chemical and physical changes based on combining different substances. These substances were developmentally appropriate because they were all household items. By using baking soda, corn starch and cream of tartar, Mrs. S eliminated the safety concern in case anything was consumed. Even though they were safe, I think it would have been beneficial to discuss as a class what they could do with the substances. This would address the safety concerns and make the lesson more developmentally appropriate. Her students are still younger, so they would have enjoyed exploring the materials, similar to the Oobleck lesson. Perhaps the students

If students were to replicate my scientific investigation, they could develop patience as the experiment involves checking it every 15 minutes for an hour. If completing multiple trials, students can develop dedication considering it may take most of a day to complete these trials. Furthermore, this experiment can allow students to become more observant and organised as it requires accuracy and bowls can be easily mixed up. Bowls with salt and sugar can be easily confused because they look so similar, and when pouring the melted liquid into measuring cups, it is important to remember what cup belongs to each of the bowls.

"I 'm in 4th grade and I love science. I have good grades, but a friend of mine has poor grades in science and I decided to help him. We want to prepare a lesson about
