
How are instruments that transmit and detect waves used to extend human senses?
Students will understand that…
 Scientific questions need to be asked so they can be tested empirically and structured in the form of testable predictions.

Data must be collected to address scientific questions and support predictions.
 Data analysis is conducted to search for regularities and patterns in observations and measurements.
 Evidence and scientific knowledge is used to construct scientific explanations, models and representations.

Mathematical reasoning and quantitative applications can be used to interpret and analyze data to solve problems.

A critical interdependence exists among science, technology, and society.
 Changes in the natural and designed world are caused by interactions.

Interactions of an object with other objects can be described by forces that can cause a change in motion of one or both interacting objects.

The interaction of an object with other objects is governed by conservation principles.

 Interactions of an object with other objects can be described and explained by using the concept of the transfer of energy.
 Attractive and repulsive interactions at a distance can be described using the concept of fields.
