Research has shown that high-stakes testing causes damage to individual students and education. It is not a reasonable method for improving schools. Test-taking anxiety is common among high school and college students. The anxiety can be quite stressful and

Animal testing Aristotle and Erasistratus were the first two early Greek physician-scientist performed experiments on living animals. In 1859‚ Charles Darwin’s evolutionary theory reinforced the conception that animals could serve as models for humans in the study of biology and physiology. Animal testing plays a large important role in pharmaceutical and medical advances‚ but many question the mortality of such use of the animal’s life. More than 100 million aninals are used for testing every single

The experiment I picked was the conservation concept‚ where the idea that merely changing the appearance of objects does not necessarily change other key properties. In other words‚ just because I put the same amount of water in a bigger case‚ doesn’t change how much water there is. I predict that both the girls would fail at conservation concept‚ and always

Using information about how you completed this ELISA experiment‚ outline a procedure for testing for antibodies in the blood. 9. Explain why in sudden outbreaks‚ it may be better to test for disease antigens rather than for antibodies. The antibodies are there to help and kill of the antigens‚ but don’t contain the whole
