Beaker

A beaker is a flat-bottomed cylindrical vessel typically made of glass or plastic, used in laboratories to hold, mix, and heat liquids. Its design often features a spout for easy pouring and measurement markings on the side. Beakers are essential tools in scientific experiments, commonly seen in chemistry, biology, and educational contexts, fostering accurate experimentation and analysis.

Beaker meaning with examples

• During the chemistry lab, students carefully poured hydrochloric acid into the beaker, ensuring they were wearing safety goggles to protect their eyes. Each step was systematic, as they monitored the reactions while noting the changes in color and temperature, illustrating the principles they learned about acid-base interactions.
• The researcher filled a beaker with a solution of sodium chloride and distilled water, stirring it gently with a glass rod. This process was critical for preparing an isotonic solution necessary for their biological experiment, where they aimed to observe cell behavior in varying salinity levels.
• As part of her cooking demonstration, the chef utilized a beaker instead of a traditional measuring cup to accurately measure out the ingredients. The markings on the side of the beaker allowed her to demonstrate the importance of precision in baking, which can make or break the final product.
• In the classroom, the teacher demonstrated the concept of density using a beaker filled with different liquids. By carefully layering the liquids based on their densities, he created a visually engaging model that helped students grasp complex scientific principles in a simple and relatable way.
• On her desk, the science student had a beaker filled with colorful liquids, each representing different pH levels. This visual aid not only helped her study for the upcoming exam but also sparked curiosity in her younger siblings, who were fascinated by the vibrant colors and seemed eager to learn more about chemistry.
