This exercise encourages students to develop hypotheses, conduct an experiment partially of their own design, and develop methods for data collection and data analysis.
A Solar Array is the main component of a PV system that requires a precise design, and is constructed based on the needs of a PV system. The energy needed to operate, charge or maintain a system is determined by the operational requirements and capacity of the system and Solar Array.
Quantifying the sedimentation velocity (terminal velocity) of a spherical particle in a liquid is of importance because it relates to areas in industry that process and transport suspensions of particles.
Throwing an object across the classroom is an example of a parabolic trajectory. Students will be able to experiment with a tennis ball, with paper and later on, with a constructed mini-rocket. The results and the effects of the different sizes and shapes of the objects will be recorded.
In this 8th grade physical science laboratory activity about chemical reactions, students are challenged to: 1) create a reaction that would be suitable to deploy a car's airbag; and 2) construct a model of an airbag that will provide enough cushion to protect a hard-boiled egg.
