Bath Bomb Experiment Analysis

The video demonstrates a small group investigation from lesson two, focusing on investigating gas from bath bombs in a bottle. It begins with measuring 100 milliliters of water, followed by inserting 8 mini bath bomb cubes into a plastic test tube. The test tube is then placed into a bottle without mixing the contents initially. The mass of the entire system is recorded before and after mixing the bath bombs with water, observing the bubbling reaction. Finally, the mass of both closed and open systems is measured to conclude the experiment.

What is the initial amount of water used in the experiment?

• 150 milliliters

• 100 milliliters

• 200 milliliters

• 50 milliliters

How many mini bath bomb cubes are used in the experiment?

• 5 cubes

• 10 cubes

• 6 cubes

• 8 cubes

What is the purpose of using the tare button on the scale?

• To calculate the total mass of the system

• To zero the scale for accurate water measurement

• To measure the weight of the bottle

• To adjust the scale for different units

What is the mass of the whole system before mixing the bath bombs with water?

• 140.8 grams

• 141.8 grams

• 143.8 grams

• 142.8 grams

What observable reaction occurs when the bath bombs are mixed with water?

• Solid formation

• Temperature increase

• Color change

• Bubbling

What is the mass of the closed system after the bubbling stops?

• 141.2 grams

• 142.2 grams

• 141.8 grams

• 140.8 grams

What is the mass of the open system after the experiment?

• 140.2 grams

• 141.2 grams

• 142.2 grams

• 143.2 grams

Why is it important to include the cap as part of the open system measurement?

• To account for all components of the system

• To maintain the original mass

• To prevent gas escape

• To ensure the system is closed
