1 - Scientific Investigation

Scientific investigation is all about exploring questions and finding answers by thinking like a scientist. When scientists investigate, they use skills like observing (noticing details with their senses), making inferences (drawing conclusions based on what they see), and predicting (making educated guesses about what might happen). They also follow steps known as the scientific method, which helps them keep their experiments organized and fair.

Your memory strategy goes here:

Metrics

Scientists collect data using the International System of Units (SI), a.k.a. the metric system. This table summarizes important facts about measuring with SI units.

You can easily convert from one metric unit to another using the “ladder method.”

Scientific Notation

Scientific notation is an easy way to write and compare very large and very small numbers, including measurements.
