Task 1
Rewrite this for a younger class: “Liquid water on the tray became water vapour. The amount remaining fell from 40 mL to 32 mL in our test.” Use “evaporation”, explain the term and keep the evidence exact.
AC9S4I06 • Homework
Communicating Scientific Findings and Ideas worksheet
Use eight independent written and practical reasoning tasks. An adult checks the actual work.
Open practiceEight independent tasks
Write and create accurate science messages for a named purpose and audience. Use separate paper for longer explanations and diagrams. An adult reviews the actual work.
Task 2
Source note: the National Museum of Australia’s Travelling Country account describes Ngurrara I, a Traditional Owner collaboration linked with Walmajarri and Wangkajunga peoples. The artwork represents Country, including waterholes. Write an acknowledgement and two sentences explaining how this example shares water and place knowledge. Do not copy the artwork or invent symbol meanings.
Task 3
Create a physical or drawn feeding model for a younger audience: leaves are eaten by caterpillars, and caterpillars are eaten by small birds. Add labels, directed links, a key and a caption stating one limitation.
Task 4
Write a short informative paragraph for school visitors about this scenario: introduced foxes eat native small mammals; those mammals eat some insects. Define predator and prey, explain a possible impact and say why the model alone cannot give an exact population count.
Task 5
Create a material recommendation for a parent choosing a model bag. Sample A bends and holds five counters but leaks; sample B bends, holds five and stays dry. The bag must meet all three needs. Write a report with a small evidence table.
Task 6
Create four lines of a song or a short performance script for the school community about saving water. Include two practical actions while preserving drinking, handwashing and other necessary water use.
Task 7
Plan a digital slide or draw its layout on paper to share these invented classroom data: matched tap-observation periods recorded 14 minutes of running before a reminder and 10 minutes after. Add a title, labelled visual, finding, and note that the data are invented.
Task 8
Show one of your created texts to a partner or adult. Ask what the text explains and who it is for. Record their feedback, make one useful revision and explain why the revision improves understanding.
Answers and adult review checks
Task 1
Answer: Evaporation changes liquid water into water vapour in the air. In our test, water remaining in the tray fell from 40 mL to 32 mL.
Require an actual audience-appropriate rewrite, accurate definition and both values; do not claim the water was destroyed.
Task 2
Answer: Credit the Traditional Owner creators and National Museum account. Explain that the collaborative artwork represents knowledge of Country, including waterholes; it communicates more than a current water measurement.
Require a written attribution and two supported statements. An adult may read the supplied note aloud. No unshared meanings or universal claims are needed.
Task 3
Answer: Leaves → caterpillars → small birds. The arrows show food and energy to the eater. The chain shows selected links and omits other foods or organisms.
Inspect the created model and caption, including actual labels and correct arrow direction; no need to handle living animals.
Task 4
Answer: A predator hunts and eats other animals; prey are animals eaten by a predator. Here foxes are predators of the small mammals. Predation can reduce mammal survival and may affect insects they eat. This model does not measure population numbers or include every influence.
Require original prose with accurate vocabulary, a causal link, appropriately cautious indirect reasoning and the model limitation.
Task 5
Answer: Recommend B for the tested purpose; A meets bending and load needs but not the dry-inside requirement. The table should retain each sample’s three results.
Inspect both a written report and an accurate two-row, three-criterion table. Require sample-specific evidence and no claim about every bag.
Task 6
Answer: Possible actions are turning taps off while soaping and reporting leaks to an adult. Accurate explanations can mention reducing unnecessary running.
Review the actual lyrics or script for two clear actions, suitable audience language and accurate claims; no invented litres-saved promise is required.
Task 7
Answer: The slide shows 14 and 10 minutes with a running-time label and explains that fewer minutes were recorded after the reminder in this example. It does not claim a measured volume saving.
Inspect actual layout and data labels, accurate values and units, the invented-data note and no unsupported causal certainty or litres conversion.
Task 8
Answer: A revision might define a science word, enlarge labels, add an evidence value or clarify the intended action without changing the facts.
Inspect original text, recorded reader feedback, revised text and reason. The adult reviews communication and scientific accuracy, not artistic polish.
