Choose a location in your home. This may seem like an easy task, but there are a number of factors that need to be taken into consideration prior to choosing a space. The room should have ample counter space, good lighting, running water and temperature control. There should be some sort of ventilation, such as an exhaust fan or at least a few windows that can be opened. Additionally, the flooring should not carpet, as chemicals in a lab can easily be spilled.
Buy storage cabinets that can be locked. Keeping dangerous chemicals away from the reach of children or animals is a very important safety feature of any science lab. Also make sure to put labels on all chemicals.
Buy safety equipment. Goggles, gloves, a first aid kit and a fire extinguisher are essential.
Purchase lab supplies specific to the type of experiments you wish to perform. This may include a microscope, test tubes, scissors and various chemicals.
