Space weather refers to the affect the Sun has on the Earth and rest of the solar system. The solar wind is a fairly constant stream of charged particles, mostly high-energy electrons and protons, ejected from the upper atmosphere of the Sun.
Students may know a little about solar energy, as some of their homes may use solar panels for heating or cooling purposes. The following projects allow students to set up their own investigations and manipulate variables surrounding photovoltaic cells.
