1-2: Finding Out
- A problem is a situation that seems to be missing some information.
- An exercise is a situation where known steps need to be taken to find a solution.
- Solving problems involves looking for pattern, making predictions, and testing the predictions.
- Often, a model can be developed that helps to solve a problem.
- A hypothesis is a testable prediction.
- A theory, based on many observations, is the most logical explanation of why things work.
- A scientific law is a summary of many experimental results that describes a pattern in nature.

1-3: Getting Real with Special Effects
- New technology, new materials, and computer assistance heave helped to make some events and objects in movies seem much more realistic than they have seemed in the past.

1-4: Exploring Science
- An experiment is an organized prodedure for testing a hypothesis.
- Typically, an experiment will have a control, which is a standard for comparison, and two types of variables.  
- Independent variables are adjusted to different values by the experimenter.
- Dependent variables have values that change with a change in an independent variable.
- Tested experiments can be done safely when everyone is aware and follows standard safety warnings.
