Can every question be answered using the scientific method? why or why not? can a theory change over time? if so, how? can a law change over time? if so, how? what is a scientific model? list the types of models and describe each one. what is the importance of the metric system? (i didn't know what subject to put this in xd)

Not always. For an idea to be considered scientific, it must be testable and observable.

 Theories may take many years to prove or disprove. In some cases, a theory needs extensive research before scientists have enough data to accept or reject it.

 Laws DO NOT change over time. You should know that

 Models are crucial tools in science. Without models, it would be difficult or impossible to observe, explain, and understand many parts of Earth and its various systems.

 1. Small-Scale Objects: Models are made to represent objects that are very small. This type of model makes it so the object being studied can be seen without a microscope. A model of a cell or an atom is an example.
2. Large-Scale Objects: Models are made to represent objects that are very large. This type of model makes it so the object being studied can be seen in a manageable area. An example of this type of model is a scale model of a building or of the solar system.
3. Distant or Unobservable Objects: Distant objects may be shown in models. For example, models are made to represent the locations of objects very far away in space. Sometimes, objects can never be seen. For instance, the interior of Earth may be shown as a model.
4. Maps: Maps are another type of model that scientists use. Street maps are a common type of map. Other types of maps help scientists to explore the ocean floor, study water flow, find oil deep in the ground, or study the surface of the moon.
5. Computer Models: Computer models and simulations are useful for predicting future events. Climate models run by powerful computers help scientists to understand and predict Earth's weather.
6. Equations and Graphs: Equations are models that use symbols (including letters and numbers) to represent data, processes, or events. Chemical equations are used by chemists to model chemical reactions. Equations may also be represented in graph form to show the relationships between sets of data.


 To minimize misunderstanding between scientists, measurement has a common language: the metric system.
