Question

What materials do you need to do this exercise?

1) Fifteen containers: five large, five medium, and five small
2) At least one 100-ml graduated cylinder
3) Larger and smaller cylinders (optional)
4) Colored water
5) Phone to take pictures
6) Chart to record estimates and actual values

Answer 1

The exercise involves measuring the volume of liquids, commonly performed in chemistry class, requiring containers, graduated cylinders, colored water, a phone for pictures, and a chart for recording.

Step-by-step explanation:

The exercise described appears to involve measuring, estimating, and recording the volumes of liquids, which is generally an activity performed in a Chemistry class. The necessary materials for the exercise include various sizes of containers, graduated cylinders for precise measurements of liquid volume, colored water to easily observe the meniscus, a phone for taking pictures of the setups or measurements, and a chart to note down the estimates and actual values observed during the experiment.

Remember to always read the meniscus at the bottom of the curve of the water level when using graduated cylinders to measure liquid volume. This is crucial for obtaining accurate readings.

The materials like micropipettes, pH meters, and Pasteur pipets mentioned in the reference are typically found in a chemistry lab and provide additional context for the kind of activities that could be performed around measuring and recording volumes in a chemistry educational setting.
