Lab Equipment Safety: Care of Measuring Tools

The video tutorial discusses tools for measuring length and mass, such as rulers, meter sticks, measuring tapes, triple beam balances, and spring scales. It emphasizes the importance of using common sense with length measurement tools and highlights the need for careful handling of mass measurement tools to avoid damage. The tutorial also explains the limitations of these tools, particularly when measuring large objects, which can damage the instruments.

Which of the following is NOT a tool used for measuring length?

• Ruler

• Meter stick

• Triple beam balance

• Measuring tape

What is a key precaution to take when using a triple beam balance?

• Use it to measure very large objects

• Handle it securely with two hands

• Keep it near the edge of the table

• Use it with one hand

Why can't a triple beam balance measure very large objects?

• It is not accurate

• It is too fragile

• It has a limited range

• It is too expensive

What can happen if a spring scale is used to measure a very large object?

• The scale will give an accurate reading

• The spring may stretch permanently

• The scale will become more sensitive

• The scale will measure faster

What is a common issue with using a spring scale incorrectly?

• It becomes easier to use

• It becomes more accurate

• It can measure larger objects

• The spring may not work properly
