Measuring Volumes and Equipment Usage

The video tutorial introduces volume measurement using water and food coloring for visibility. It explains the equivalence of milliliters and liters and demonstrates measuring different volumes using containers, pipettes, and syringes. Two challenges are presented to measure specific volumes using available tools, enhancing problem-solving skills.

Why is food coloring added to the water in the containers?

• To make the water evaporate faster

• To change the water's temperature

• To make the water easier to see

• To make the water taste better

How many milliliters are equivalent to one liter?

• 500 milliliters

• 1000 milliliters

• 1500 milliliters

• 2000 milliliters

What is the purpose of using a pipette in the experiment?

• To heat the water

• To measure large volumes

• To remove small amounts of liquid

• To freeze the water

How many milliliters can the pipette measure at once?

• 1 milliliter

• 2 milliliters

• 3 milliliters

• 4 milliliters

In Challenge 1, what is the total volume of purple water available?

• 1250 milliliters

• 500 milliliters

• 750 milliliters

• 1000 milliliters

What is the first step to measure 750 milliliters in Challenge 1?

• Pour 250 milliliters into a container

• Pour 500 milliliters into a container

• Pour 750 milliliters into a container

• Pour 1000 milliliters into a container

What equipment is used to measure 167 milliliters in Challenge 2?

• A 1000 milliliter container

• A 100 milliliter cup and pipette

• A 250 milliliter cup, pipette, and syringe

• A 500 milliliter cup

What is the first volume measured in Challenge 2?

• 250 milliliters

• 150 milliliters

• 100 milliliters

• 200 milliliters

How many milliliters does the syringe add in Challenge 2?

• 3 milliliters

• 5 milliliters

• 7 milliliters

• 10 milliliters

What is the final step to reach 167 milliliters in Challenge 2?

• Add 1 milliliter

• Add 2 milliliters

• Add 3 milliliters

• Add 4 milliliters
