02: Scientific Investigation Scenario 1. 2. Describe why the investigation above is not adequate to explain what types of rocks will dissolve in water. They need to use the same rocks from the backyard. You can’t compare different types of rocks. Just because it appears to shrink doesn’t mean it actually did. You need real data of what the mass of the rocks were before the rainstorm. 2. Using what Christopher and Kate have already observed‚ suggest a possible hypothesis regarding how the

Homelessness: Scientific Method Research SOCS 185 February 8‚ 2011 Homelessness is an ongoing social problem in the U.S. On top of being without shelter‚ these individuals are faced with a vast array of dangers that individuals with shelter do not face. These dangers may include exposure to inclement weather conditions‚ lack of health care‚ hate crime activity‚ substance abuse‚ and ultimately death. Acquiring homeless rates with intentions of conducting data research can be difficult being

Assessment activity 1 1. When conducting research on behalf of your organisation or for a client organisation‚ how will you determine the most appropriate data sources to use? In this case the most suitable data source will be a desk research because this information will have already been gathered‚ analysed and reported on by other companies. It means that you will not waste time and money doing what others before you have done. 2. Why are cross checks and cross references necessary?

How Do You Write a Methodology If you want to make your research appear more credible there is no option but to understand in detail‚ how to write a methodology. A research methodology will help you showcase your knowledge of using alternative methods that help in presenting your research topic more valid. The best way to demonstrate your research is by using a qualitative or quantitative research process. The following are the general guidelines that you should follow depending on the type of

In Example 2‚ the independent variable is violence (mild vs. none)‚ and the dependent variable is aggressiveness on the playground. The hypotheses in Examples 1 and 2 are examples of directional hypotheses. In a directional hypothesis‚ we predict which group will be higher or have more of something. Sometimes we have a nondirectional hypothesis. Consider Example 3. Example 3 It is hypothesized that the child-rearing

Every life created by god is equal. Bearing that in mind‚ a huge amount of people have been no-animal-testing users. They strongly propose that animals shall not be used in scientific researches.

The dependent variable is the rate of the growth of the plant and then the independent variable would be the time of day that she waters the plant. 2. Five variables that should be controlled during the experiment is the amount of sunlight‚ room temperature‚ amount of water‚ the time of day the plant is watered and the certain type of plant. To make sure the plants get the same amount of sunlight‚ make sure to put them both

Should animals be used for scientific experimentation? For many centuries people have experimented on animals. There are two main reasons for doing this: first‚ two find out more about the animal themselves‚ and‚ secondly‚ to test substances and procedures to see if they are harmful with a view to deciding whether or not they can be used on human beings. Therefore animals should be used for animal experimentation. Experiments on animals should be considered on a case-by-case basis. The proper
