Eggsperiment Purpose Is an egg similar to a human cell? Hypothesis If the egg is put in milk, then the shell will grow back. According to Mama Natural, “High-quality eggshells contain 27 essential microelements but they’re mostly composed of calcium carbonate, a form and structure that’s very similar to our bones and teeth.” Also, according to My Plastic Free Life, “eggshell powder contains roughly 400 milligrams of calcium per gram.” Since the milk I use, 2% Fat, has 295 milligrams in one cup…

Pimples abide approaching to dead skin cells naturally produces oil in excess skin blocking pores. A common misconception about blackheads is that they are caused by dirt. Blackheads are created if the pores are open and clogged pores until it turns into a black color as the air hits the open, clogged pores. Washing your face or force several times not one day gets rid of blackheads. If anything, that will dries out your skin and cause irritation. It will also cause more oil to be produced,…

Background: Isopods, or what are often called pill bugs, are crustaceans. Isopods live in damp environments. They can be found under rocks, logs and in soil. In this lab, 10 isopods were given a choice between salt water or regular water chambers to test their preference. The results were recorded every 30 seconds over a period of 10 minutes. Problem: It is known that isopods have a preference for moisture.This lab will specifically test whether or not an additive will affect a pill bug's…

The main objective of this lab was to collect 〖Co〗_2 gases that were given off by the Alka-Seltzer tablets and to identify experimental masses. The volume of gas was 724 liters, or 723.86 cm and the experimental mass was .0894 grams. A balance scale was used before and after the reaction to record the change in overall mass. First, using the scale, the flask, balloon, and Alka-Setlzer tablets were measured, 259.4 ±.05 Grams were found. What created the “〖Co〗_2 gases to be trapped” were the…

In this investigation, the mass (g) of a beaker and a graduated cylinder were calculated and recorded into a lab notebook. The density of distilled water was calculated without any NaCl by measuring the mass of a sample of water in a beaker, and then subtracting the mass of the beaker to leave the mass of water. This measurement was recorded into a lab notebook in Table 1 under “Total Mass of Solution” and “Mass of solution”. The contents of the beaker are then transferred to a graduated…

Thermodynamics of Cheetos Purpose: to analyze the caloric content of snack foods, by determining the calories of heat given off by a Cheeto, or other snack foods, as it burns. Procedure: The food sample (Cheeto) was placed on a food holder, and the initial combined mass of the food holder and the Cheeto was measured and recorded. Using a graduated cylinder, 50-100 milliliters (ml) of water was measured and added to an empty soda can that was cut in half and cleaned. The soda can was…

Aim: The aim of this investigation is to determine the effect of water temperature on the time it takes for an aspirin tablet to dissolve. Hypothesis: The boiling water will have the quickest time to dissolve the aspirin tablet. This is because its molecules have more energy and are vibrating more rapidly than the cold water. Cold tap water will have the slowest time to dissolve the aspirin tablet because it has the least kinetic energy. Why? Apparatus: Equipment: Image Kenwood Kettle Pyrex…

Frame: The purpose of this lab is to determine if the iron given in the experiment is Fe (II) or Fe (III). Knowing what chemicals are present in a reaction and what chemicals are produced is significant information that can be applied to real world situations. An example of this is rust. Rust usually occurs when iron reacts with water. By being aware of this, substances can be made to remove unwanted rust. The mass of the collected samples will decrease as it is dried due to evaporation. Excess…

your regular trash in every state except California, where they must be recycled. After disposing of leaking batteries, you may need to clean the device they were in. Although people often refer to battery acid, potassium hydroxide is a base. To remove it from a device's battery contacts, use an acid like lemon juice or vinegar and a cotton swab.…

The water bottle brand Poland Springs had mostly clear water, it was extremely transparent, except there was a very light gray tint to the water that was barely noticeable. Also, when the water was first poured into both warm and cool temperature test tubes, there were some air bubbles in the test tubes. However, after 2 days, the bubbles seemed to have disappeared from both test tubes in both environments. Within both environments there was evaporation, however, evaporation along with water…
