"Thinking About Science Themes" covered in this article: Science is a process of discovery that helps society by answering questions. The questions involve a specific problem that, when solved, will improve something that society values. Let's take this research as an example. Society places a value on healthy pine trees for a number of reasons. In this study, the scientists studied pine trees that people were going to use during the winter holiday season to decorate their homes. When an insect attacks and damages or kills a large number of holiday pine trees, society considers this a problem. Fewer holiday trees might mean higher prices for the people who want to buy them. Trees damaged by insects might also be less attractive. The problem can be stated as a question, such as 'What can be done to prevent an insect from attacking pine trees?' Scientists can ask many different questions that stem from the same problem. In your own words, develop another question that scientists could ask, based on the problem of insects attacking pine trees. Specific "Thinking About Science" Themes:"Thinking About Environmental Themes" covered in this article: You know that plants have fragrances. Think about the fragrances of flowers and newly mown grass. Scientists call these fragrances volatiles (vol uh tilz). They are released when a chemical inside the plant is exposed to air. When exposed to air, the chemical evaporates, which causes it to be dispersed in the air. Many plants have volatiles that humans cannot smell. Insects, however, can smell many of these volatiles. Most insects smell volatiles using special cells on the surface of their antennae. The volatile attracts the insects to the plant. They can then use the plant for food, as a place to lay their eggs, or as habitat. Name one example of an insect that uses its antennae to find food. In this research, the scientists were interested in finding out how to prevent a particular insect from being attracted to pine trees. In this case, when the insect smells the volatile and finds the pine tree, its use of the tree damages the tree and can even kill it.
