What to Focus On
- Science begins with wonder and simple questions.
- Investigation means asking focused questions and testing ideas.
- Observation, experimentation, and conclusion are parts of scientific method.
- Change only one thing at a time in an experiment.
- Controlled variables in the puri experiment include dough thickness, flour type, oil temperature, and dropping method.
- Observed variables may be yes/no answers or measurements.
- Everything around us is made of tiny particles.
- Particles move very little in solids and freely in gases.
- Elements are pure substances.
Common Mistakes to Avoid
Scientific investigation means only looking carefully at something and then guessing the answer.
In an experiment, many things can be changed together because more changes give faster results.
The things that are observed in an experiment and the things that are changed in an experiment are the same.
