Science, Society and Ethics: a skill companion

A small set of reusable sheets that grow one Human Endeavour idea: science can describe the options for a problem, but choosing between them means weighing environmental, social, ethical and economic effects, and different people weigh them differently. Students map who gains and who pays, score options with weights and watch the best choice change, test a water plan for a town in drought, and attach conditions that reduce a cost. Print the scaffolds once and slot them into the science lessons you already teach.

AC9S8H03
examine how proposed scientific responses to contemporary issues may impact on society and explore ethical, environmental, social and economic considerations

What a skill companion is

Human Endeavour ideas are not a topic of their own. They grow inside the science units a class teaches all year: every Year 8 topic meets a real decision, from treating burns and organ donation to quarries, wind farms, desalination and food waste. So this pack is not a full term of lessons. It is three reusable scaffolds, a map of where they fit, and a short stand-alone lesson for teaching the idea on its own first.

Start here: five minutes

  1. Read the pairing map on the next page: it gives a proposed response, with its gains and costs, for every Year 8 topic.
  2. Print the decision sheet whenever a topic meets a real choice, and the case study when you teach mixtures and separation.
  3. Cut out the cards once. They are reused all year, and the blank cards fit any topic.
  4. Open the free interactive unit on your board when you want the quarry decision as a worked example.
  5. Run the one-page mini-lesson first if you want to teach the idea before folding it into a topic.

The step up from Year 7

In Year 7 students sorted the effects of a response into environmental, social, ethical and economic, and weighed the options. In Year 8 they ask who gains and who pays, including people with little voice such as future generations; they weight the four kinds of effect and find that the best option depends on the weights, which come from values, not from the science alone; and they attach conditions that keep a response’s gains while reducing its costs.

On the board
This pack is the printable half of a free interactive unit. On screen, students pick each option in “Proposed responses to the quarry: what is gained, what is given up”, sort concerns with “Economic” and “Not economic” in “Which concerns are about the economics of the quarry?”, and add findings in “How new findings reshape the proposed response”.

Where the idea fitsPairing map

A real decision in every Year 8 topic

Every Year 8 science unit meets a contemporary issue where science proposes a response. This map names one for each topic, with its main gains and costs, and which scaffold to reach for. You do not run these as extra lessons; you fold them into the science you teach.

The three moves, and the picture that backs each one

When you want a worked example on the board, open the interactive unit and use the picture that matches the move.

How the scaffolds build the idea

The decision sheet maps who gains, who pays and who has little voice, then scores options against the four kinds of effect with weights, and changes the weights to see the best choice move. The case study weighs four ways a town in drought could secure its water. The cards sort statements into gains, costs and the conditions that reduce a cost.

Scaffold 1 · Decision sheetOne per student

Who gains, who pays, and what matters most?

NameClassDate

Science can say what each option will do. Deciding between them means weighing the effects, and different people give different effects different weight. Map the people first, then score the options.

The proposed response:

A. The people

Who gains
people or living things better off
Who pays or bears the costs
money, health, land, time
Who has little voice
future generations, wildlife, people far away
Who must be asked first
Traditional Owners, landholders, neighbours

B. Score the options, then weight them

Score each option from 1 (poor) to 5 (good) for each kind of effect. Give each kind a weight from 1 (matters a little) to 4 (matters most). Total = each score times its weight, added up. The quarry scores are filled in as an example.

Water for a town in drought

NameClassDate

A coastal town has had three dry years and its dam is low. Four responses are on the table. Several Australian cities, including Perth, Sydney, Melbourne and Adelaide, already run desalination plants, and Perth also tops up its groundwater with purified recycled water.

A. The options

OptionHow it worksIn a long droughtOther effects
A desalination plantPushes sea water through a membrane that lets water through but not salt (reverse osmosis).Works in any droughtNeeds a lot of electricity; the leftover brine, about twice as salty as sea water, goes back to the sea; costly to build.
Purified recycled waterCleans wastewater through several stages until it is safe to drink, then stores it underground or in a dam before use.Works in any droughtUses less electricity than desalination; some people dislike the idea of drinking recycled water.
A new damStores river water behind a wall across a valley.Only refills when it rainsCheap to run once built; floods the valley’s habitat, farms and any heritage places in it.
Restrictions and rainwater tanksLimits how water is used, and catches rain from roofs.Tanks run dry in a long droughtCheapest; everyone has to change habits, and it may not be enough on its own.

B. Weigh them

An environmental effect of the dam:
A social effect of purified recycled water:
An ethical question about the desalination brine:
An economic effect of restrictions and tanks:

Mini-lesson · Teacher planAbout 30 minutes

A town meeting about a quarry

Use this stand-alone lesson to teach the idea on its own, before you fold it into a science topic. The class holds a town meeting about the quarry in the interactive unit. Six people speak from their own point of view, the class sorts what they raise into the four kinds of effect, and then everyone sees how the weight they give each effect changes the decision.

Lesson flow (about 30 minutes)

5 minPrepare a view
Each group reads its role and writes the two points it will make, using facts from the unit.

Ask: “What does your person gain or lose if the quarry goes ahead?”

10 minThe meeting
Each role speaks for about a minute. The class sorts each point into environmental, social, ethical or economic.

Ask: “Which concern is not about money, but still matters a great deal?”

10 minWeigh it
Show the board (see the box). Students weight the quarry scores on scaffold 1 as their role would, then as the council would.

Ask: “Same scores, different weights, different answer. What does that tell us about who should decide?”

5 minSort the cards
Tables sort the cards, then match each condition to the cost it reduces.

Ask: “Card D has no condition yet. What condition could reduce it?”

Running it shorter? Hold the meeting and sort the concerns, and weigh the options in your next science lesson.

On the board
For a worked example, open the unit and pick each option in “Proposed responses to the quarry: what is gained, what is given up”. Then add the findings one at a time in “How new findings reshape the proposed response”.

Answers and look-fors

Decision sheet: the quarry

Who gainsThe quarry company and its workers; builders and home buyers through cheaper stone; the council through rates.
Who pays or bears the costsFamilies beside the truck route (dust, noise); the downstream farmer (water); wildlife on the ridge.
Who has little voiceFuture residents who inherit the changed ridge; the plants and animals living there.
Who must be asked firstThe Traditional Owners, for whom part of the ridge holds meaning; neighbouring landholders.
Weights (environmental, social, ethical, economic)Approve as proposedApprove with conditionsRefuse and source elsewhere
The council, weighing everything equally (2, 2, 2, 2)182826
Families living near the ridge (3, 3, 2, 1)163233
A local business group (1, 1, 1, 4)242316

The same scores pick a different best option for each group: the council’s even weights favour approval with conditions, the families favour refusal, and the business group favours approval as proposed. The science sets the scores; values set the weights. A condition at standard: dust sprays and a tree buffer along the truck route, with the council checking monthly.

Case study: water in a drought

Environmental (dam): floods a valley’s habitat. Social (recycled water): some people dislike drinking it, so trust and explanation matter. Ethical (brine): is it fair to sea life near the outlet, and is the mixing checked? Economic (restrictions): cheapest, but businesses that use water may suffer. Little voice: future residents, sea life, farmers in the valley. A recommendation at standard names one option, a reason from the table (such as working in any drought), and a condition (such as renewable electricity for a desalination plant). Science can tell the town how each option works and what it does; it cannot tell the town how much weight to give each effect.
