Teaches why phases happen and how to identify waxing/waning phases.
Pick a lesson.
Interactive simulations, clear explanations, and practice questions for major space topic. From beginner basics to advanced astronomy.
Middle School
Core space content most students are expected to learn.
Teaches mass vs weight and how gravity depends on mass and distance.
Teaches magnetic field lines, poles, and how field strength changes with distance.
Sort all 118 elements into their correct positions on the periodic table.
Sort examples into physical or chemical changes and learn the science behind each.
Add protons, neutrons, and electrons to create any element with a 3D rotating atom visualization.
Navigate lab scenarios and learn safe practices through realistic consequences.
Analyze famous discoveries and identify the 7 steps scientists use to answer questions.
Mix RGB lights, split white light through prisms, and discover why the sky is blue.
Examine rock samples and identify them as igneous, sedimentary, or metamorphic.
Teaches why seasons happen: Earth's tilt changes sunlight angle and day length (not distance from the Sun).
