science (2277 words) |
 | Science is first and foremost a set of logical and empirical methods which provide for the systematic observation of empirical phenomena in order to understand them. |
| Science consists of several specific sciences, such as biology, physics, chemistry, geology, and astronomy, which are defined by the type and range of empirical phenomena they investigate. |
| Finally, science is also the application of scientific knowledge, as in the altering of rice with daffodil and bacteria genes to boost the vitamin A content of rice. |
| Questions and Answers: What is hands-on learning, and is it just a fad? (2916 words) |

| Science education in elementary schools first existed as selections contained in the eighteenth and nineteenth century children's didactic literature (Craig, 1957; Underhill, 1941). |
| What children in elementary schools need is not abstract scientific principles, not the systematic study of any or all the sciences (an impossible thing), but simple, objective, convincing demonstrations of the main ideas and uses of science in the home and neighborhood and in the larger world beyond. |
