Although developed with college classes in mind, many of our simulated laboratories are also ideal for advanced science high school classes. Based on feedback from teachers, we created special collections of our college labs covering topics from osmosis and the cell cycle to natural selection and Hardy-Weinberg equilibrium to ecology. These specially discounted "high school only" collections can be used on their own or as complements to field and wet labs and provide students a taste of the college curriculum.
Stellarium is a free open source science planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.
