With the sentence method, you write down the key ideas from a lecture in a numbered list. You can combine this method with other techniques such as using abbreviations or acronyms so that you can further reduce note-taking time and space.
The sentence method allows you to record a lot of information and is easier than writing down whole sentences or paragraphs. On the other hand, you usually end up with an extensive list of ideas. Related ideas are not grouped together and the main ideas and supporting ideas are not clearly distinguished.
Because of this, you would need to take an extra step, which involves reviewing, editing, and organizing your notes to make sense of what you have written down.
Your revised notes might look like this:
TOPIC: CHANGES IN MATTER
Matter: has mass, occupies space
Can undergo 2 types of change: physical and chemical
Phys: id and properties do not change
Example: boiling water returns to water
Chem: id and prop change
Example: burning wood becomes ash and gas
Evidence: change in properties, like bubbles (not in H2O), change in form; temp/color change
