About This Drill
ACT Science — Research Summaries — Drill 2 is a Science practice drill covering Research Summaries. It contains 5 original questions created by Brian Stewart, a Barron's test prep author with over 20 years of tutoring experience.
ACT Research Summaries questions assess understanding of experimental variables and results. This drill presents three experiments examining osmosis in potato tissue under varying sucrose concentration, time, and temperature, requiring data comparison and evaluation of the students' experimental controls.
Questions in This Drill
- According to Table 1, in which sucrose solution did the potato cylinders neither gain nor lose mass?
- Experiment 2 was designed primarily to investigate how which of the following affects the rate of osmosis?
- Based on Tables 2 and 3, which of the following statements best compares the results of Experiments 2 and 3?
- Based on the data in Tables 1 and 2, if a potato cylinder were soaked in a 0.2 M sucrose solution for 60 minutes at 25°C, the most likely result would be:
- The students used potato cylinders with the same initial mass (5.0 g) in all three experiments. What was the most likely reason for this design choice?
