Measure a Bean, Why?

A beaker and a graduated cylinder differ in their primary use and accuracy. Which statement best describes this difference?

• A beaker is used for mixing and rough measurements, while a graduated cylinder is used for precise volume measurements.

• A beaker is used for precise volume measurements, while a graduated cylinder is used for heating substances.

• A beaker and a graduated cylinder are both used only for heating liquids.

• A beaker is used for storing chemicals, while a graduated cylinder is used for filtering solutions.

What are the units for mass (weight) and for volume?

• The unit for mass (weight) is grams (g), and the unit for volume is milliliters (ml) or cubic centimeters (cm³).

• The unit for mass (weight) is liters (L), and the unit for volume is kilograms (kg).

• The unit for mass (weight) is meters (m), and the unit for volume is seconds (s).

• The unit for mass (weight) is newtons (N), and the unit for volume is joules (J).

Mass and volume are different because:

• Mass measures the amount of matter, while volume measures the space an object occupies.

• Mass measures the space an object occupies, while volume measures the amount of matter.

• Mass and volume are the same property of matter.

• Mass is only measured in liters, while volume is measured in grams.

How many millimeters are in a centimeter?

• 10

• 100

• 1

If a bean measured 2 cm, how many millimeters is it?

• 20

• 2

• 200

• 0.2

What tool is used to measure volume?

• Graduated cylinder

• Thermometer

• Balance scale

• Ruler

If a beaker is filled with 200 ml of water and a goldfish is added, the water level rises to 240 ml. What is the goldfish’s volume?

• 40 ml

• 20 ml

• 60 ml

• 100 ml

If a beaker is filled with 400 ml of water and a tennis ball is added, the water level rises to 620 ml. What is the volume of the tennis ball?

• 220 ml

• 120 ml

• 400 ml

• 1020 ml

After soaking, the bean’s width and length:

• increase

• decrease

• remain the same

• shrink slightly

The bean’s mass changed after soaking.

• The mass increased after soaking.

• The mass decreased after soaking.

• The mass remained the same after soaking.

• The mass fluctuated randomly after soaking.
