Phenomenon Students may have seen wet or liquid and dry measuring cups in the kitchen and wondered if a wet cup is equal in volume to a dry cup.
Essential Question How does the accuracy of a piece of glassware help determine its use? Activity Objectives Determine the percent error in volume for several pieces of laboratory glassware. Make a claim about the acceptable laboratory use of each piece of glassware based on accuracy.
B: Defining and Delimiting Engineering Problems There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem.
Safety Procedures and Precautions Remind students to be mindful of where they place glassware. Teacher Preparation and Disposal Group glassware prior to the activity. This volumetric glassware is designed as a very long, narrow glass tube. The tube has a little rubber bulb at the center and a narrow tip. The hash marks are indicators of the tube getting filled. The bulb at the center creates a vacuum that helps suck air and draw the liquid in the device. The glassware is primarily used as a media dispenser which helps transfer liquids from one container to another during experiments.
Pipettes are highly accurate with their accuracy. The size comes in a range of 12 inches to 24 inches and the graduations on the side can measure liquids within a 0.

Beakers and Flasks Beakers and Erlenmeyer flasks are some of the most often used equipment in a science lab. The flasks can be recognized by their conical base and long narrow necks.
On the other hand, the beakers are nothing but large glass jars with a spout used for pouring. What are they used for? Due to their large capacities, the vessels are mainly used to store and mix solutions to carry out chemical reactions. The vessels might be larger than others on this list but they provide nothing but crude readings. Graduated Cylinders Graduated cylinders are tall narrow vessels.
Like the name suggests this type of glassware contains proper markings that are generally present on the sides. In addition to that, it has a glass bottom that functions as a spout to pour the liquid out. Unlike the beakers, they are specifically made for measuring liquid volumes.
The cylinders come in a size range of about 5 ml to ml. Fairly high. The level of accuracy of a graduated cylinder is slightly better than beakers and flasks. This means that a ml graduated cylinder has 1 ml divisions on them. And a 10 ml graduated cylinder will give out readings as precise as 0.
