Investigable Questions: a skill companion
A small set of reusable sheets that grow one inquiry skill: noticing a pattern, asking a question that tests the relationship behind it, and predicting a result with a reason, including knowing when a pattern can no longer be trusted. Print the scaffolds once and slot them into the science lessons you are already teaching.
What a skill companion is
Inquiry skills are not a topic of their own. They grow inside the science units a class teaches all year, such as Habitat Conditions and Survival; Earth, Sun and the Day-Night Cycle; Electrical Circuits and Energy; and Reversible and Irreversible Changes. 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 skill on its own first.
Start here: five minutes
- Read the pairing map on the next page: it shows which scaffold fits which science lesson.
- Print the question maker and the prediction sheet, one each per child, whenever a lesson starts from a pattern children have noticed.
- Cut out the question cards once. They are reused all year, and the blank cards fit any topic.
- Open the free interactive unit on your board when you want a worked example of the skill.
- Run the one-page mini-lesson first if you want to teach the skill before folding it into a topic.
No science background needed
This pack is written for the busy generalist teacher. Each scaffold explains itself in plain words, and the answer sheet gives the card key, the worked predictions, a model question and prediction for every Year 6 topic, and a quick three-level guide. The step up from Year 5 is the relationship: children say how two things are linked (the more light, the taller, up to a point), predict inside the range they tested, and explain why a prediction far outside it is a guess.
Slot the skill into your science lessons
The same skill of posing a question about a relationship and predicting fits into every science unit. This map shows a pattern children can notice in each Year 6 topic, an investigable question about the relationship behind it, and which scaffold to reach for. You do not run these as extra lessons; you fold them into the science you teach.
| When you teach | Pattern children can notice | Investigable question | Scaffold to slot in |
|---|---|---|---|
| Habitat Conditions and Survival (AC9S6U01) | Seedlings on the windowsill grow taller than those in the dim corner | How does the number of hours of light each day affect how tall bean seedlings grow in 10 days? | Question maker, then the prediction sheet |
| Earth, Sun and the Day-Night Cycle (AC9S6U02) | In winter it is dark before sport practice ends; in summer it is light | How does the month of the year affect the number of hours of daylight in our town? | Question maker, then the question cards |
| Electrical Circuits and Energy (AC9S6U03) | The torch glows brighter with two cells than with one | How does the number of cells affect how brightly a bulb glows, within the bulb’s rating? | The mini-lesson, then the prediction sheet |
| Reversible and Irreversible Changes (AC9S6U04) | Ice melts faster in a drink than on a plate | How does the temperature of water affect how long an ice cube takes to melt? | Prediction sheet, then the question cards |
| Any science topic | A pattern a child spots for themselves | The child names what changes and what is measured, the relationship expected, and a prediction with a reason | Question maker first, then a blank card |
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 children are working on.
- Turn a pattern into a question a fair test can answer, with one thing to change and one to measure: “Frame the question: change only the number of cells”.
- Read the relationship in measured results, and question a reading that breaks it: “See the pattern in the brightness readings” and “Find the reading that breaks the pattern”.
- Tell a prediction reasoned from the pattern from a guess: “Sort the reasoned predictions from the guesses”.
How the scaffolds build the skill
The question maker turns something a child noticed into an investigable question about a relationship, naming what to change, what to measure and what to keep the same, and the relationship they expect. The prediction sheet reads a pattern that rises and then levels off, predicts one result inside the tested range and one just outside it, and asks when a pattern stops being safe to use. The question cards sharpen the first step: some questions test a relationship, some ask for one fact, and some are opinions no measurement can settle.
Ask about a relationship
Science often starts with a pattern you notice: when one thing changes, another seems to change too. An investigable question asks how the first thing affects the second, so that a fair test can find out.
What I noticed
My investigable question
To test it fairly
The relationship I expect
Teacher note: if a child ticks “Not yet”, the question usually has nothing to change or nothing to measure. Help them name one of each, then reword it with “How does ... affect ...?”.
Predict inside and outside the pattern
A reasoned prediction uses the pattern you measured. Inside the range you tested, the pattern guides you well. Outside it, the pattern may change, so the further out you go, the less sure you can be.
A. Read the pattern
Class 6B grew bean seedlings for 10 days under a lamp on a timer. Each group got a different number of hours of light a day; the pots, soil, water and seeds were kept the same. They measured the average height.
| Light (hours) | Height (cm) |
|---|---|
| 2 | 3 |
| 4 | 6 |
| 6 | 8 |
| 8 | 9 |
| 5 | ? |
| 10 | ? |
Mark your two predicted points on the dashed lines of the graph.
B. My own prediction
A relationship, one fact, or not science?
Cut out the cards. Lay down the three grey heading cards, then sort the question cards under them. For each question that does not test a relationship, try rewriting it on a blank card so that it does.
Teacher note: four cards go in each pile. The answer sheet lists which is which, and why. The blank cards let children write their own questions and swap them with another table to sort.
From a pattern to a prediction you can trust
Use this stand-alone lesson to teach the skill on its own, before you fold it into a science topic. A ruler ramp, a marble and a stack of books give the class a relationship of its own in a few minutes: the higher the ramp, the further the marble rolls. The three scaffolds then turn it into an investigable question, two predictions and a sort.
We are learning to
- notice a pattern between two things and turn it into an investigable question,
- predict a result inside the range we tested, with a reason from the pattern,
- explain why a prediction far outside the range is less sure.
Success criteria
- I can ask a “How does ... affect ...?” question that names what to change and what to measure.
- I can say which of two predictions I trust more, and why.
You need
- a ruler with a groove (or card folded into a channel), a marble, a stack of books, a tape measure and masking tape,
- the question maker and the prediction sheet (scaffolds 1 and 2), one each per child,
- the question cards from scaffold 3, one set per table, and the interactive unit on your board (optional).
Lesson flow (about 30 minutes)
| 5 min | Notice a pattern Roll the marble down the ramp resting on 1 book, then on 4 books, and mark where it stops each time. Ask: “What changed when the ramp was higher? Where else have you seen that?” |
| 10 min | Ask about the relationship Each child fills the question maker. Show the board (see the box). Ask: “If we raise the ramp and swap to a bigger marble, can we tell what changed the distance?” |
| 10 min | Measure and predict Roll from 1, 2 and 4 books, three rolls each, and record the middle distance. Children predict 3 books (inside the range) and 8 books (far outside), then test 3 books. Ask: “Why are we surer about 3 books than about 8?” |
| 5 min | Sort the questions Tables sort the question cards under the three heading cards. Ask: “This card asks for one fact. What could change, and what could you measure?” |
Running it shorter? Stop after the question maker, and pick up the measuring and the cards in your next science lesson.
Watch for these ideas
- A question that names only one thing, like “how far does a marble roll?”. Ask what they would change.
- Changing two things at once, such as the ramp height and the marble. Then nobody can tell which change mattered.
- Trusting a prediction far outside the tested range as much as one inside it: at 8 books the marble may bounce or skid.
Make it easier, make it bigger
- Easier: give the frame “How does the height of the ramp affect ...?” and let children finish it.
- Bigger: graph the class’s results and decide whether the pattern is the more, the more all the way, or levels off.
Answers and look-fors
The next sheet has the card key, the worked seedling predictions, a model question and prediction for each Year 6 topic, and a quick three-level guide.
Answers and look-fors
Question cards
| Card | Question | Pile | Why |
|---|---|---|---|
| A | How does the number of hours of light each day affect how tall bean seedlings grow? | Tests a relationship | Change the hours of light, measure the height. |
| B | Is a gecko a nicer pet than a frog? | Not science | ‘Nicer’ is a matter of taste. |
| C | What time did the sun set yesterday? | Just one fact | One known answer; nothing is changed. |
| D | How many cells does our classroom torch hold? | Just one fact | Count once; there is no second thing to measure. |
| E | How does the temperature of water affect how long an ice cube takes to melt? | Tests a relationship | Change the water temperature, time the melting. |
| F | Is summer the best season of the year? | Not science | ‘Best’ is an opinion. |
| G | Which colour of wire looks the coolest? | Not science | Looks are a matter of taste; brightness does not depend on it. |
| H | What is the temperature of the tap water right now? | Just one fact | One reading, with nothing changed. |
| I | How does the number of cells in a circuit affect how brightly the bulb glows? | Tests a relationship | Change the cells, measure the brightness (within the bulb’s rating). |
| J | How does the month of the year affect the number of hours of daylight in our town? | Tests a relationship | Compare the months, measure the daylight hours from sunrise and sunset times. |
| K | Which plants grow in the school garden? | Just one fact | A list to observe; no relationship is tested. |
| L | Is melted chocolate more delicious than solid chocolate? | Not science | ‘Delicious’ is a matter of taste. |
A rewrite at standard turns, for example, ‘What is the temperature of the tap water right now?’ into ‘How does the time of day affect the temperature of the tap water?’.
Predict inside and outside the pattern: the seedlings
Each 2 more hours of light, the height grew by 3, then 2, then 1 cm (3, 6, 8, 9): the gains shrink each time, so the pattern rises and levels off. At 5 hours, inside the range and between the readings at 4 and 6 hours, about 7 cm is a confident prediction. At 10 hours, just outside, the next gain should be about 0 cm, so about 9 cm, said with less certainty. At 24 hours a day nothing was tested anywhere near, so the pattern cannot say; only a test can.
Question maker and prediction sheet: what a good response sounds like
| Topic | A question at standard | A prediction at standard |
|---|---|---|
| Habitat Conditions and Survival | How does the number of hours of light each day affect how tall bean seedlings grow in 10 days? | I predict 6 hours will grow taller seedlings than 2 hours, because plants use light to make their food, so more light should mean more growth, up to a point. |
| Earth, Sun and the Day-Night Cycle | How does the month of the year affect the number of hours of daylight in our town? | I predict the longest days in December and the shortest in June, because in December our half of Earth is tilted towards the Sun. |
| Electrical Circuits and Energy | How does the number of cells affect how brightly a bulb glows, within the bulb’s rating? | I predict three cells will light the bulb more brightly than two, because each added cell pushes more current through the filament, which glows hotter. |
| Reversible and Irreversible Changes | How does the temperature of water affect how long an ice cube takes to melt? | I predict ice will melt fastest in the warmest water, because warmer water passes heat to the ice more quickly. |
A quick three-level guide
| Move | Working towards | At standard | Beyond |
|---|---|---|---|
| Pose a relationship question | asks about one thing only, or asks for an opinion | asks how one thing affects another, naming what to change and what to measure | names the relationship expected and how to keep the test fair |
| Make a reasoned prediction | predicts with no reason | predicts inside the tested range from the pattern, and says why | uses the size of the steps to predict a number, and says how sure it is |
| Know the limits of a pattern | trusts a prediction far outside the range as much as one inside it | explains why a prediction outside the tested range is less sure | suggests a test that would check the pattern further out |
A child at standard poses a question about a relationship and predicts its result with a reason, inside the range that was tested. The skill grows all year, so keep the scaffolds coming back in every science topic.
