10 lessons in this unit
Scientific investigation questions
Learn to turn curiosity into a testable scientific question, tell testable questions from opinions, and rewrite vague questions so they can be answered by measuring.
Lesson 2Hypotheses and predictions
Learn that a hypothesis is a testable explanation and a prediction says what will happen, write both in an if-then-because form, and see why a wrong prediction still teaches us.
Lesson 3Variables
Learn that a variable is anything that can change in a test, name the independent, dependent and controlled variables, and spot them in simple investigations.
Lesson 4Controlled investigations
Learn to design and run a controlled investigation with a clear question, one changed variable, repeated trials and a written method others can follow.
Lesson 5Measurement accuracy
Learn to measure length, mass, volume, time and temperature accurately with the right tool and units, read scales carefully, and tell accuracy from precision in simple words.
Lesson 6Data collection
Learn how to collect data carefully by observing and measuring, tell quantitative from qualitative data, use tally charts and record sheets, and avoid common recording mistakes.
Lesson 7Tables and graphs
Learn to organise results in tables and draw bar charts and line graphs with titles, labelled axes and equal scales, and choose the right graph for the data.
Lesson 8Evidence analysis
Learn to read tables and graphs for patterns, calculate averages and ranges, spot anomalies, and use the results to say whether the evidence supports the hypothesis.
Lesson 9Scientific explanations
Learn to write a scientific explanation using the claim, evidence and reasoning pattern, and to use vocabulary and ideas from science to explain why results happened.
Lesson 10Investigation evaluation
Learn to evaluate a whole investigation by judging fairness, reliability and accuracy, suggesting improvements, and posing a new question that follows from the results.
