Here is a list of the main scientific concepts students learn in fifth grade! These science concepts are organized into categories. To start, just click on any link. You can do these in any order at any pace that's right for you.

Chemistry Learn first-hand the fundamental principles of this essential science as you perform real chemistry experiments. Experiment with fuels and combustion, make your own hydrochloric acid, separate mixtures, produce oxygen gas, split the water molecule, fire copper ions across a solution, capture oxide gases, create a magnesium battery, and more with this section in chemistry.
DNA molecules Life Science (Human Anatomy) A comprehensive course that teaches the fundamental concepts in human physiology and anatomy. Discover how to build a working robotic hand, measure your lung capacity, filter blood, detect genetic traits, chemically fingerprint your friends, and make a frog totally disappear.
Earth Science Far from static rocks and minerals, water remains the most influential Earth Science system that we experience every day, since it influences our energy, vegetation, biology, climate, and weather patterns. You'll get to learn about the important connections between the water systems of earth and the sun, whose energy powers the water cycle and climate.
Astronomy Discover Martian sunsets, eclipses and transits, what drives Neptune’s internal furnace when it’s so far from the sun, learn how binary planetary systems work, and more as you  construct a spectrometer to split light into its rainbow signatures, investigate the electromagnetic spectrum, and so much more!
