The student can measure the volume of CO2 collected in each balloon using a measuring cylinder or by displacing water in a container. They can also use a gas syringe to measure the amount of CO2 collected. Additionally, they can track the time it takes for the balloons to fill up with CO2 to make comparisons.

How can the student make a quantitative observation of the CO2 collected in the balloons?

The student can measure the volume of CO2 collected in each balloon using a graduated cylinder or syringe to calculate the total volume of gas. They could then compare the mass of the balloons before and after the experiment to determine the mass of CO2 collected. Finally, they could use a color-changing pH indicator to analyze the acidity of the collected gas, indicating the presence of CO2.


A student found that the mass of the naphthalene collected was less than the mass determined by difference. What would account for the smaller amount of the naphthalene collected?

The naphthalene solid has a significant vapor pressure, as indicated by its strong odor. The solid naphthalene will evaporate, decreasing the mass of solid naphthalene present.m collected + m evaporated = Delta m


A beaker contains table salt dissolved in water describe one method a student could use to separate salt?

The student can use the process of evaporation to separate salt from water. By heating the solution in the beaker, the water will evaporate, leaving salt crystals behind. These salt crystals can then be collected once all the water has evaporated.


Scientists use critical thinking skills throughout the process of research or experimentation. A student notices that their energy level always seems to decrease when they drink soda but they seem to?

This observation could lead the student to conduct further experiments to determine if there is a correlation between drinking soda and decreased energy levels. They could design a controlled study to investigate this relationship and gather quantitative data to analyze the potential effects of soda consumption on energy levels. The process would involve forming a hypothesis, designing an experiment, collecting data, and drawing conclusions based on the findings.

Evidence of teaching effectiveness can include student performance data, student evaluations, peer evaluations, and classroom observations.


Is student rank in class qualitative or quantitative?

Student rank in class is considered a qualitative measure, as it represents a student's position relative to their peers rather than a numerical value with consistent intervals. While ranks are often represented by numbers (e.g., 1st, 2nd, 3rd), they categorize students into groups based on performance without implying equal differences between ranks. Therefore, student rank is more about ordinal classification than quantitative measurement.
