Measurement Quiz

A group of students is using a balance scale to compare the weights of 3 balls as shown. What might the students conclude about the balance scale?

1. The balance scale measures the volume of the balls accurately.
2. The balance scale shows the weight based on the amount of air in each ball.
3. The balance scale is not useful because it only works with objects that are the same shape.
4. The balance scale compares the mass of each ball to find which is heavier or lighter.

Answer: (d) The balance scale compares the mass of each ball to find which is heavier or lighter.

Elisa is experimenting with two cups: Cup A (Steel) and Cup B (Glass). She fills both cups with the same volume of water and starts heating them. She measures the temperature of the water in both cups every five minutes using a thermometer, as shown in the table below. What should Elisa conclude after 20 minutes? Time (minutes) Temperature of Water in Cup A (Steel) Temperature of Water in Cup B (Glass) 0 20 20 5 25 23 10 30 26 15 35 27 20 40 30

1. The steel cup heated up the water faster than the glass cup.
2. The glass cup heated up the water faster than the steel cup.
3. The temperature of water in both cups increased at the same rate.
4. The steel cup and the glass cup heated the water at different rates.

Answer: (d) The steel cup and the glass cup heated the water at different rates.

Lily has a rectangular block of chocolate. She cuts the block into 8 smaller equal pieces, as shown in the figure below. After cutting, Lily wants to compare the total mass and volume of the chocolate with the original block. Which of the following statements is true?

1. The total mass of the chocolate stays the same, but the total volume of the chocolate becomes smaller because the pieces are smaller.
2. The total mass of the chocolate stays the same, and the total volume stays the same because cutting the block does not change the material or size.
3. The total mass of the chocolate becomes larger, but the total volume stays the same.
4. The total mass of the chocolate becomes smaller, and the total volume stays the same because the pieces take up less space.

Answer: (b) The total mass of the chocolate stays the same, and the total volume stays the same because cutting the block does not change the material or size.

Consider the passage given below and answer the following question: Understanding Measurement Tools We use different tools to measure things in our daily lives. A ruler helps us measure the length of objects, like the width of a book or the height of a plant. It is marked with units such as centimetres or inches. To use it, place the ruler along the object and check where it ends. A tape measure is similar to a ruler but is flexible. It’s great for measuring long or curved objects, like a table or room. Pull the tape out, place it along the object, and read the measurement. A weighing machine tells us how heavy something is, like a bag of flour or our body weight. Stand still on the scale, and the number will show your weight. Thermometers measure temperature. They can tell how hot or cold something is, like a cup of tea or your body. Just place the thermometer where you need to measure and read the temperature. A clock helps us measure time. It has hands that point to numbers on a face. The longer hand shows minutes, and the shorter hand shows hours. Looking at the clock tells us what time it is. When studying how a plant grows from a seed to its full height, which tool would be best for measuring how tall the plant grows?

1. Tape measure
2. Weighing machine
3. Clock
4. Thermometer

Answer: (a) Tape measure
