Ideas for Progress: Science, Range 20–23

To enhance their skills in each science-related strand, students who score in the 20–23 score range on the ACT® college readiness assessment may benefit from activities that encourage them to do the following:

Score Range 20–23
Interpretation of Data
  • become familiar with scatterplots
  • identify and compare scales used in different data presentations
  • study a simple data set to determine how one variable is related mathematically to another variable
  • explain why a particular data presentation is most appropriate to use for a specific data set
  • examine line graphs to determine if they show a direct or inverse relationship between variables
  • use information from popular sources (e.g., newspapers, magazines, the Internet) to enhance understanding of similar information found in science textbooks
  • create a set of guidelines to help peers learn how to combine results from different experiments into one data presentation
  • read a science article, and describe how the values of variables are related and how one changes in relation to the other
  • compare raw data from the same experiment, or from different experiments, to determine how many and what types of data representation are needed
Scientific Investigations
  • perform several repetitions of an experiment to determine the reliability of the results
  • predict potential findings of new experimental trials based on past experimental trials
  • describe how experimental methods accomplish the goal of answering the question driving the experiment
  • describe how an experimental design could be manipulated to answer a new question
Evaluation of Models
  • evaluate whether the data produced by an experiment adequately support a given conclusion
  • examine data collected in a new experiment to evaluate whether it supports or contradicts a conclusion from a previous experiment
  • determine the parameters or limits of how known models can be applied to specific situations (e.g., the model of Newtonian physics cannot be applied to subatomic particles, climate models are modified when new data becomes available)
  • create a visual representation that shows the similarities and differences between two competing models proposed to explain the same scientific phenomenon
  • engage in class discussions to critique the strengths and weaknesses of other groups’ experimental findings
  • determine how new findings impact predictions previously made with a model
