Question

Which Science and Engineering Practice BEST describes the following statements?

"1. Use a weighing paper and balance to measure 0.2 g of baking soda.

2. Use a graduated cylinder to measure 250 ml of vinegar and pour it into the 400 ml beaker.
3. Start a timer, pour the baking soda into the vinegar, and record the time when bubbles stop forming. Do not stir the mixture.
4. Record your observations in the Qualitative Data section of the lab.
5. Dump the resulting solution down the drain and rinse the beaker.
6. Repeat steps 1-4 two more times for a total of 3 trials.
7. Repeat steps 1-5 with 0.5 g of baking soda.
8. Repeat steps 1-5 with 0.8 g of baking soda."
Options:
A. Constructing Explanations and Designing Solutions
B. Using Mathematics and Computational Thinking
C. Planning and Carrying Out Investigations
D. Developing and Using Models

Answer 1

The Science and Engineering Practice that best describes the given statements is Planning and Carrying Out Investigations.

Step-by-step explanation:

The Science and Engineering Practice that best describes the given statements is Planning and Carrying Out Investigations.

1. Statement 1 involves using a weighing paper and balance to measure the mass of baking soda, which is a part of the planning process of the investigation.
2. Statement 2 involves using a graduated cylinder to measure the volume of vinegar and pouring it into a beaker, which is a part of the carrying out the investigation.
3. Statement 3 involves starting a timer, pouring the baking soda into the vinegar, and recording the time when bubbles stop forming, which is another part of carrying out the investigation.

Therefore, the Science and Engineering Practice that best describes the given statements is Planning and Carrying Out Investigations.
