Study pushes, pulls, friction, and balanced testing so conclusions come from evidence instead of guesswork.
In an investigation, change only one factor at a time when possible. That makes it easier to see what really caused the result.
Open one card at a time, read the text together, and use the audio button when hearing the line once helps.
force basics
Forces act by pushing or pulling objects.
Example: Pushes and pulls are forces.
friction
A rough surface usually creates more friction than a smooth one.
Example: Friction affects motion.
fair test
Only one variable should change if you want useful evidence.
Example: Fair tests control the variables.
science reasoning
Reliable testing needs more than one attempt.
Example: Repeated trials improve trust in results.
