10 lessons in this unit
Reviewing scientific observation
Review how scientists observe with their senses and simple tools, and learn to tell an observation from a guess.
Lesson 2Asking investigable questions
Learn to ask questions that can be answered by looking, measuring or testing, and to tell them from questions that cannot be tested.
Lesson 3Making simple predictions
Learn to make a prediction, a thoughtful guess based on what we know, and to compare it with results.
Lesson 4Comparing objects
Learn to compare objects by size, shape, colour, texture and mass, using words like bigger, smaller, heavier and lighter.
Lesson 5Measuring using simple tools
Learn to measure length, mass, time and volume with simple tools and standard units, and to read scales carefully.
Lesson 6Recording observations
Learn to record observations clearly with words, numbers, tables and tally marks so that others can understand them.
Lesson 7Drawing scientific diagrams
Learn to draw clear scientific diagrams with a pencil, a title and labels with lines.
Lesson 8Organising observations
Learn to organise observations by sorting into groups, making simple tables, Venn diagrams and block graphs.
Lesson 9Explaining results
Learn to explain what results show, using because, and to say whether the results support the prediction.
Lesson 10Science safety
Learn the safety rules for science work: listening, tidying, handling equipment, protecting eyes and hands, and what to do in an accident.
