Teaching template 1 Science words in use: compare, evidence and conclusion Learning goal: I can use science words to describe results and support a careful conclusion. Practice data This invented example is for language practice, not a real experiment. Group Factor compared: hours of light each day Measured outcome: growth after two weeks Water A 6 hours 8 cm Same amount B 3 hours 5 cm Same amount Water is the only condition explicitly stated as equal. No other condition is specified. Match the science words variable: a part of an investigation that can change result: what was observed or measured evidence: information used to support an idea compare: describe what is the same or different pattern: a relationship that appears in the observations conclusion: a statement that answers the question using evidence Use the words 1. The factor compared was ______. The measured outcome was ______. 2. Water was the only condition explicitly stated as equal. Another condition I would keep equal in a future comparison is ______. 3. Group A grew ______ cm. Group B grew ______ cm. 4. Group A grew ______ cm more than Group B. 5. The evidence shows ______. 6. My conclusion is ______ because ______. Check the limit Does this small practice data set prove that light always causes more growth? Write one reason for your answer.

Teaching template 1 Science words in use: compare, evidence and conclusion: teacher notes Teacher check Expected: factor compared, hours of light; measured outcome, growth after two weeks; only stated equal condition, water. Group A grew 3 cm more. Pupils should say the fictional values show a difference in this example, not prove that light caused it. An additional condition such as plant type is a possible future control, not a condition stated as equal in this table.
A teaching sequence
Explain six common science words and use evidence and because to connect a result with a cautious conclusion.
Read the six investigation terms
Read variable, result, evidence, compare, pattern and conclusion with their displayed definitions.
What does evidence mean in this invented practice task?
Identify factor, outcome and stated control
Identify hours of light as the factor compared and growth after two weeks as the measured outcome. Water is the only condition explicitly stated as equal; no other condition is specified.
Which condition is actually stated as equal, rather than assumed?
Complete frames through table evidence
Underline the part of the practice data that supports a statement and complete the sentence frames using the table.
What value supports the comparison between Group A and Group B?
Write a careful conclusion with a limit
Write a short conclusion. Include one limit: two groups alone do not show that the pattern will always happen.
Why do these two groups not prove that light always causes more growth?
Before you teach
Look for the thinking behind an answer, choose the support your class needs and leave room for an independent response.
What to look for
Expected: hours of light is the factor compared; growth after two weeks is the measured outcome; water is the only condition explicitly stated as equal. Group A grew 8 cm and Group B 5 cm, so A grew 3 cm more. The fictional values show a difference in this example, not that light caused it. Follow up: ask which additional condition, such as plant type, pupils would keep equal in a future comparison; the table does not state that it was equal here.
Give a little support
Pre-teach variable, result and evidence with gestures or labelled examples. Let pupils rehearse the sentence aloud before writing and keep the values visible.
Take the idea further
Ask pupils to suggest one additional condition to keep the same and one way to repeat the practice investigation. Explain why more observations would strengthen a conclusion.
Things to keep in mind
The values are invented for language practice, not experimental evidence. Hours of light is the factor compared and growth after two weeks is the measured outcome. Water is the only condition explicitly stated as equal; no other condition is specified. The values show a difference in this example only and do not prove that light caused the growth.
Keep the idea. Make it yours.

Extra Page
This one-page English science language template supplies invented growth values: Group A receives six hours of light and grows 8 cm; Group B receives three hours and grows 5 cm. Pupils match terms and write a cautious conclusion using evidence and “because.”
Storytime Sidekick
The note that both groups received the same amount of water, while no other condition is specified, gives pupils a concrete limit to include in a conclusion. The data are explicitly for language practice, not a real experiment.
After the Bell
Underline the values, time period and stated water condition before writing. Use a sentence frame that reports the difference and then names what remains unknown.
Open Book Pause
These invented values cannot support a real claim about light and plant growth. Do not infer that water is the only controlled factor; the source says other conditions are unspecified.
