This is an automatically translated description

You are now holding in your hands a notebook that describes the physics laboratory work for grade 9. It will help you in preparing for laboratory work, performing experimental research, and presenting the results of your work. The descriptions of the activities contain questions that you should answer orally in preparation for the experiment, as well as step-by-step tasks that you should perform. These tasks will help you conduct your research and draw conclusions. Measurement and calculation results should be recorded in the spaces provided or in tables, and intermediate mathematical transformations should be performed in the cells provided. After each activity, there are control questions that will help you summarise the knowledge you have acquired during the activity. In your conclusions, you should describe how you have achieved the objective of the laboratory. Additional creative tasks are intended for those who are interested in physics, do not stop there and want to learn more.

Before doing the work and preparing the report, carefully read the theoretical information provided in the textbook and repeat the safety rules for working in the physics room.
