Reversible and Irreversible Changes: a full term of science

Ten ready-to-teach lessons for Year 6 Chemical sciences. Print this pack and the term is prepared: every lesson has a plan, talk prompts, a student worksheet, cards or tickets, and answers.

AC9S6U04
compare reversible changes, including dissolving and changes of state, and irreversible changes, including cooking and rusting that produce new substances

Start here: five minutes to Monday

  1. Skim the term at a glance on the next page.
  2. Print the lesson you need (plan, worksheet, cards).
  3. Gather everyday items under You need on the plan.
  4. Open the free interactive unit on your board.
  5. Teach from the plan: timings, prompts and answers are on one page.

No science background needed

Written for the busy generalist teacher. Plain words, common muddles, and model answers are on every plan. Safety: no open flames or boiling water unless an adult controls a warm-water step named on the plan.

On the board
This pack is the printable half of a free interactive unit. On-screen pictures include: “Sort the changes”, “Dissolving sugar is reversible”, “Changing state is reversible”, “Cooking an egg is irreversible”, “Rusting is irreversible”. Lesson plans name which picture to show.

Curriculum links (Australian Curriculum V9)

The term teaches AC9S6U04. Lessons also work these Inquiry and Human Endeavour descriptors:

AC9S6I01pose investigable questions to identify patterns and test relationships and make reasoned predictions
AC9S6I02plan and conduct repeatable investigations to answer questions including, as appropriate, deciding the variables to be changed, measured and controlled in fair tests; describing potential risks; planning for the safe use of equipment and materials; and identifying required permissions to conduct investigations on Country/Place
AC9S6I03use equipment to observe, measure and record data with reasonable precision, using digital tools as appropriate
AC9S6I04construct and use appropriate representations, including tables, graphs and visual or physical models, to organise and process data and information and describe patterns, trends and relationships
AC9S6I05compare methods and findings with those of others, recognise possible sources of error, pose questions for further investigation and select evidence to draw reasoned conclusions
AC9S6I06write and create texts to communicate ideas and findings for specific purposes and audiences, including selection of language features, using digital tools as appropriate
AC9S6H01examine why advances in science are often the result of collaboration or build on the work of others
AC9S6H02investigate how scientific knowledge is used by individuals and communities to identify problems, consider responses and make decisions

Dear families

This term in science, Year 6 explores reversible and irreversible changes. We use observation, simple tests and clear science words. Ask: What did you notice today? What evidence did you use?

Try this at home
