Planning & Investigating
Skills used before and during laboratory investigations in Science 10 Unit A.
You’ve encountered many of these ideas in earlier grades. In Grade 10, they are applied more deliberately to chemical investigations, measurement, and evidence-based decision making.
These skills help you work safely, collect reliable data, and think clearly about what your results mean, which are all essential for success in chemistry.
Topics in this section
Lab Safety and WHMIS
Understand laboratory safety rules, hazard symbols, and how to make safe decisions when working with chemicals.
Laboratory Equipment and Measurement
Learn how to use common lab equipment correctly and why accuracy, precision, and units matter.
Observations vs. Interpretations
Practice separating what you directly observe from the conclusions you draw based on those observations.
Physical vs. Chemical Properties and Changes
Use evidence to determine whether a change is physical or chemical and why the difference matters.
Diagnostic Tests and Chemical Identification
Explore how chemical tests are used to identify substances and why reliable evidence is essential.
Some classes may also complete an external WHMIS certification as part of their laboratory preparation. Your teacher will provide details if this applies to your course.
