About this activity
Eight science terms defined in student language: hypothesis, a testable prediction you make before the experiment; variable, the one thing you change on purpose; data, the measurements you actually recorded; conclusion, what the data lets you claim; adaptation, a trait that helps a species survive. These are the words a lab report is graded on, and students lose marks on them while understanding the science.
How to use it in a session
Anchor each one to an experiment the student has actually run. Variable means nothing in the abstract and everything when it is the one thing they changed last week. The hypothesis-data-conclusion trio is worth doing as a sequence rather than three separate cards, since they describe three stages of the same process and students confuse them in exactly that order. Fifteen minutes covers the eight with examples.
What to listen for
Listen for a conclusion that outruns the data. What the data lets you claim is a deliberately careful definition, and students routinely write conclusions their measurements do not support — which is a language problem about the word conclusion as much as a scientific one. Watch variable, which students often use for anything that changes rather than the one thing they changed.
Carrying it home
Any lab report or science homework supplies the vocabulary. Asking what the variable was, or what the data actually showed, is a two-minute conversation with direct effect on the marks.
Questions
- What grades is this for?
- Sixth through eighth, matched to middle school science coursework.
- Do I need an account?
- No, all eight cards play free in the browser.
- Why is science vocabulary a speech-language target?
- Because comprehension of academic text and instruction is a language skill. A student who understands the science and misuses hypothesis and conclusion is losing marks for language reasons.
