Irina-Kira [14]

   Pick a topic.

   Research.

   Hypothesis.

   Experiment.

   Construct an exhibit for results.

   Write a report.

   Practice presenting.

Pick something you are interested in, something you'd like to think about and know more about

Then do some background research on the topic.

Decide whether you can state a hypothesis related to the topic (that is, a cause and effect statement that you can test), and follow the strict method listed above, or whether you will just observe something.

Design and carry out your research, keeping careful records of everything you do or see and your results or observations.

Construct an exhibit or display to show and explain to others what you hoped to test.

Write a short report that also states the same things as the exhibit or display, and also gives the sources of your background research.

Practice describing your project and results, so you will be ready for visitors to your exhibit at the science fair.

What were the common causes and risk factors found between the majority of the skin disorders?
Paladinen [302]
Skin is the first line of defense mechanism of our immune system. It acts as a barrier for pathogenic and opportunistic microorganisms. However, skin itself has a microbiota that does not allow other microorganisms to invade or colonize. Any wound, cut or change in the pH of skin due to environmental conditions or any disease might lead to the entry of the opportunistic microorganisms inside the skin. This leads to several skin disorders such as dermatitis, eczema, cellulitis, warts, etc. Thus, it is extremely important to keep the skin hydrated and healthy to avoid any kind of microbial invasion.
