In this experiment the students will be determining the pH of household products along with other solutions using several different indicators as well as a pH meter. The experiment also has the student determining what the buffer solution is in an aqueous solution. The student will also be testing the pH of milk of magnesia and will see how it affects the stomach acid. Lastly the student will be using the carbon dioxide found in their breath to neutralize a base.…
You may want to use a new beaker for this experiment so the products and/or water don’t mix.…
My name is Madison Johnson. I am in the 9th grade. I am in Mrs. Logan’s biology class. I am doing my project on “The Magic Floating Egg”. Eggs sink in normal tap water and I am testing whether or not changing the density of water will make the egg float. I was looking at projects on sciencebuddies.org and I saw that multiple people had done this. I am trying to prove that when you add a certain amount of salt to water, it will make it more dense. I took pictures of the results. This information can be useful because we can test the density of salt water versus the density of normal tap water..…

A dental implant is a small titanium rod that looks like a screw. The screw replaces the tooth root and the dental crown replaces the visible portion of the tooth. Implants are surgically embedded…

The purpose of this experiment is to observe reactions of chemicals that can be found in consumer products. Through observation, students should be able to interpret the chemical reactions and determine some characteristics, such as pH and solubility. Method…
When the experiment was finalized the vinegar solution enlarged the eggs mass. Before the vinegar solution it was 55.1 grams and after the solution it was 67.9 grams. The volume of the egg was also increased. At the beginning it was 50 mL after the solution it was 60 mL; it had a 10 mL difference. It is visible that a hypotonic solution was present. This rejects the hypothesis made. When the egg was placed in 150 mL of vinegar and left intact overnight the egg did sink to the bottom and remain that way, however, the mass was increased instead of keeping it the same, by approximately 13 grams. Furthermore, the volume was also increased it did not remain the same. By analyzing the data it can be determined that the water had a larger concentration and did not have to balance out with the vinegar. The vinegar acted in a peculiar way although it eroded the shell and took some weight off the water flowed inside the egg due to the low concentration of the vinegar.…

Early Childhood Caries (ECC), also referred to as Baby Bottle Tooth Decay (BBTD), is a disease that causes severe and swift decay of baby teeth. It usually begins with the upper front teeth, then moves on to the molars. Unfortunately, by the time most parents notice the decay, it may be too late to do anything about it. That's why it's important to understand the causes of ECC and learn how to prevent it before it even starts.…
Dental Implants – Dental implants are artificial tooth roots that anchor replacement teeth. Usually made of titanium or another biocompatible material, they are surgically placed in the socket of the jawbone and covered with a dental crown. Implants are a secure and permanent tooth replacement option.…
I will ask the students to submerse a hard-boiled egg (one per students) in dark soda and ask the students what they think it will happen to the eggs.…
Background: Pepsinogen is an inactive protein that is the mucus lining of the stomach. When converted to pepsin, the enzyme is used to break down large or undigested protein they has been absorbed by the small intestine. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). In the intestine the gastric acids are neutralized (pH 7), and pepsin is no longer effective.…
