How to make a rocket using common cooking ingredients
Use baking soda and vinegar to create a chemical reaction which launches a rocket (a film canister) sky high.
Spaghetti is denser than water and, therefore, sinks when placed in water. When spaghetti is placed in a solution of baking soda and vinegar, the spaghetti rises to the surface due to the carbon dioxide gas that adheres to it. When the spaghetti reaches the surface, the gas is released, and the spaghetti sinks again.
How to grow your own yeast fungus
The yeasts are one very important group of fungi. The common yeast used in baking bread grows very fast. You can complete an experiment in two days! The basic idea in this method is to measure the amount of carbon dioxide (CO2) released during the growth of yeast.
What are the most effective cleaning agents for our teeth?
The hypothesis is baking soda, salt, hydrogen peroxide, and water will be the best stain remover (and the least expensive) because they are all good cleaning substances.
What is the effect of heat and acids on milk proteins?
In this experiment you will examine the effects of heat and acid on the protein casein in milk. The process produced a substance that was sticky like a glue.
What is the dissolution rate of lactase pills
The purpose of this experiment was to determine the rate of dissolution for several dairy digestive supplements, lactase pills. I became interested in this idea because I am lactose intolerant and I wanted to buy the fastest acting pill. The information gained from this experiment would help consumers know which brand of lactase pills will dissolve fastest so they can make the best purchasin
How do Increased CO2 Levels Affect Plant Growth?
The problem with increased CO2 is its affect on global warming. CO2 is not a pollutant but it does trap infrared heat from radiating back into space. This phenomenon is known as the greenhouse effect. This global warming then affects global ecosystems by having effects on water vapor and other climate features. If CO2 levels continue to rise, the results to the planet are difficult to gauge. Som
Examine how much Carbon Dioxide is produced by different gas sources? This helps us understand the impact of these gas sources on global warming.
The purposes of this experiment is to compare the amount of Carbon Dioxide (CO2) produced by four different sources of gases.
Do different methods of cooking potatos produce a different taste?
To compare different heating methods for rate of cooking and for impact on final product quality. This will be accomplished by cooking potatoes and carrots for varied times with varied heating procedures.
What is fermentation technology and how can this be demonstrated with yeast?
The purpose of this experiment is to observe the results of cellular respiration of yeasts, using grape sugar as a substrate and yielding carbon dioxide and ethanol.
