Charts can be a useful tool in teaching science. They provide an engaging visual medium that can help students understand and interpret complex information in a clear, concise way.
They are also useful for monitoring labs and detecting systematic errors in laboratory analyses. This article discusses the use of charts in laboratory lessons to teach students critical thinking skills and how to use quality control (QC) tools to solve biases in their lab analysis results.
Laboratory Techniques Chart
Labs are fun but they can also be hazardous if you don’t know what you’re doing. Luckily, there are charts to help guide you and your students through the maze that is the lab. The Laboratory Techniques Chart is a full-color chart that features 23 panels highlighting the best and brightest laboratory tools and techniques. It’s like having a laboratory manual at your fingertips, but in a format that you can hang on the wall.
The chart is mounted on black Snap-Grip trim. Printed on the tear-proof synthetic stock with top and bottom stiffening rods, the chart measures 36″ x 44″. It’s one of the most useful lab supplies you’ll ever buy. It’s a must-have in any aspiring biochemist’s toolbox. You may even find yourself using it in your own lab after all. The Laboratory Techniques Chart is a good bet for labs that are looking to save money and time while improving the safety and quality of the lab experience.
Laboratory Safety Chart
The Laboratory Safety Chart is a set of symbols that help lab workers identify the hazards present in their area. They are standardized, using pictograms, and are adopted by laboratories around the world as part of The Globally Harmonized System of Classification and Labeling of Chemicals (GHS).
The corrosive material hazard symbol is used to warn employees about the presence of a substance that can eat away at or burn skin. All employees who work with corrosive substances should be properly trained and wear protective clothing and personal protective equipment (PPE) when working with these chemicals.
Health hazards in a laboratory include carcinogens, respiratory sensitizers, reproductive toxins, aspiration toxins, and target organ toxins. These chemicals can cause serious, long-term health problems if not handled correctly.
Fire safety is an important aspect of a lab and a must-have for any laboratory. Employees should be properly trained and know what to do in case of a fire. This includes knowing where the fire extinguisher is located and how to use it effectively.
Laboratory Equipment Chart
There are many different types of lab equipment that can be used in any laboratory. However, there are some standard pieces that every lab must have to function properly.
These include a Bunsen burner, lab stands with rings or clamps, and crucibles for melting and testing metals at high temperatures. They are all essential pieces of kit that you won’t be able to work without!
A test tube is another piece of non-reactive chemistry lab equipment that’s used to hold samples in the laboratory. They are available in many different sizes and come in either glass or plastic materials.
A jar is another type of container that’s used in a science lab to store liquids. They are usually narrow-mouthed for easy pouring and can be made of either plastic or glass. They come in many different sizes and stem lengths as well.

Laboratory Procedures Chart
A constant reminder of proper laboratory procedures, this full-color chart features 23 brightly-colored panels that illustrate a wide range of lab equipment and techniques. From a laboratory burner, test paper, buret, pipet, tongs, balance, and filtering to measuring liquid volumes, setting up distillation, and collecting gas by water displacement.
These procedures are shown in a step-by-step fashion with easy-to-read captions, so every physical science and chemistry class can benefit from this reference chart. It’s printed on tear-proof synthetic stock with top and bottom stiffening rods complete with eyelets for easy hanging.
Control charts are a visual tracking system to help identify when a procedure is not meeting data-quality objectives. The chart can be used to detect problems before they become serious and allow analysts to pause and find solutions, eliminate the source of the problem, or prevent an out-of-control situation from occurring.
