Apply scientific ideas to design test and refine a device that converts energy from one form to another.
Waves and their Applications in Technologies for Information Transfer
Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.
Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.
Generate and compare multiple solutions that use patterns to transfer information.
Earth's Place in the Universe
Support an argument that the apparent brightness of the sun and stars is due to their relative distances from Earth.
Represent data in graphical displays to reveal patterns of daily changes in length and direction of shadows day and night and the seasonal appearance of some stars in the night sky.
Develop a model using an example to describe ways the geosphere biosphere hydrosphere and/or atmosphere interact.
Describe and graph the amounts and percentages of water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth.
Earth and Human Activity
Obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment.
