Microscopy is one of the most important techniques used in biology, and the microscope is considered the backbone of studying biology. This is because most details of living organisms, such as cells, algae, fungi, and bacteria, cannot be seen by the human eye. But with the aid of a microscope, biologists can study them. So National Geographic Ultimate Dual Microscope Kit is the perfect STEM kit if you want to practice your skills in microscopy. It includes 10 curated slides of various biological specimens, two sets of optical glass lenses, a Petri dish, a mini geode, and a Microscopes Learning Guide. This set also includes a brine shrimp experiment where you can track the brine shrimp's life cycle! An excellent way, indeed, to introduce biology!
