ILEARN Applied Learning 3 — Questions and Answers
Question 1: A student surveys 10 friends about their favorite lunch and uses the results to claim 'all Indiana students prefer pizza.' What is wrong with this conclusion?
- The survey should have been about dinner
- The sample size is too small and not representative of all students (Correct answer)
- Pizza is not a valid survey topic
- The conclusion is correct
Correct answer: The sample size is too small and not representative of all students
A sample of 10 friends is not large or diverse enough to represent all Indiana students, making the generalization invalid.
Question 2: A student is writing a research paper and finds three websites with different facts about the same topic. What should the student do?
- Use the website with the most colorful design
- Use only the first website found
- Cross-reference the information using additional credible sources (Correct answer)
- Combine all three websites' claims without checking
Correct answer: Cross-reference the information using additional credible sources
Cross-referencing multiple credible sources helps verify accuracy and identify which information is reliable.
Question 3: A student measures the length of a pencil five times and gets slightly different measurements each time. What does this variation MOST likely indicate?
- The pencil is changing size
- There is some degree of measurement error (Correct answer)
- The ruler is defective
- The student is not trying hard enough
Correct answer: There is some degree of measurement error
Small variations in repeated measurements typically reflect human measurement error or tool precision limits, not actual changes in the object.
Question 4: A student is asked to evaluate a classmate's argument. Which question should the student ask FIRST?
- Is the argument written neatly?
- Does the argument have a clear claim supported by evidence? (Correct answer)
- Is the argument long enough?
- Does the argument use difficult vocabulary?
Correct answer: Does the argument have a clear claim supported by evidence?
A strong argument must begin with a clear claim that is backed by relevant evidence, which is the foundation of logical reasoning.
Question 5: A student growing plants for a science fair wants to test whether sunlight affects plant growth. Which setup is the BEST controlled experiment?
- Use different types of plants in different amounts of sunlight
- Use the same type of plant with some in full sun and some in no sunlight, keeping all other conditions equal (Correct answer)
- Water some plants more than others
- Plant seeds in different soils and place them all in the sun
Correct answer: Use the same type of plant with some in full sun and some in no sunlight, keeping all other conditions equal
A controlled experiment changes only one variable (sunlight) while keeping all other conditions the same to isolate its effect.
Question 6: A student has 30 minutes to complete a project with three tasks. Task A takes 15 min, Task B takes 10 min, Task C takes 5 min. In what order should the tasks be completed to finish on time?
- C, B, A — shortest first
- A, B, C — longest first
- Any order; time will work out the same (Correct answer)
- Skip Task A to save time
Correct answer: Any order; time will work out the same
The total time is 30 minutes regardless of order, so any sequence works as long as all tasks are completed efficiently.
Question 7: Which of the following is an example of applying knowledge from math class to a real-world situation?
- Memorizing multiplication tables for a test
- Calculating how much paint is needed to cover a bedroom wall (Correct answer)
- Reading a story about a mathematician
- Watching a video about geometry
Correct answer: Calculating how much paint is needed to cover a bedroom wall
Calculating the amount of paint needed requires applying area formulas to a practical, real-world context.
