Determining substance density, studying elastic properties of bodies, and measuring the coefficient of sliding friction.
The 8th-grade material is often divided into theoretical control, practical training, and laboratory works: Determining substance density
The 9th-grade workbook contains approximately 8 laboratory works: studying elastic properties of bodies
Each workbook usually follows a standard format: Preparation for the experiment , (step-by-step instructions), Data tables for results, and Conclusions . Data tables for results
Volume of solids and liquids, size of small bodies, and mass of bodies using weighing methods.
