Yes, the CBSE Class 7 syllabus includes practical or project-based components. These components are designed to enhance the students' understanding and application of the concepts learned in different subjects. Here are some details about the practical or project-based components in the CBSE Class 7 syllabus:

Science:
- The Science syllabus includes various practical experiments and activities that students need to perform in the laboratory. These experiments are aimed at helping students understand scientific concepts, develop practical skills, and learn scientific methods.
- Some of the practical experiments in Class 7 Science involve topics such as heat, light, electricity, acids and bases, and natural resources. Students are required to perform these experiments, record observations, and draw conclusions.
- Apart from experiments, students are also given projects related to different topics in Science. These projects may involve research, data collection, analysis, and presentation. Projects help students develop research skills, critical thinking, and presentation skills.

Mathematics:
- The Mathematics syllabus in Class 7 also includes practical components. Students are encouraged to solve real-life problems using mathematical concepts and skills.
- The syllabus includes word problems that require students to apply mathematical knowledge to solve practical problems. These problems can involve topics such as fractions, decimals, percentages, ratios, and geometry.
- Additionally, students are given projects or assignments that involve practical applications of mathematical concepts. These projects may include activities like measuring and calculating distances, areas, volumes, or conducting surveys and analyzing data.

English:
- In the English syllabus, students are often assigned project-based tasks like writing essays, stories, or reports. These tasks require students to research, gather information, organize ideas, and present their work effectively.
- Students may also be assigned group projects, where they need to collaborate with their peers to perform tasks such as creating presentations, dramas, or debates on specific topics.
- These projects and activities help students improve their communication skills, creative thinking, and critical analysis.

Social Science:
- The Social Science syllabus in Class 7 includes practical components such as map work, project work, and field visits. Students are required to study and analyze maps, interpret data, and understand geographical and historical concepts through practical applications.
- Students are also assigned project work that involves researching and presenting information about different historical events, cultures, or geographical features. These projects help students develop research skills, data analysis, and presentation skills.

Overall, the CBSE Class 7 syllabus includes practical or project-based components in subjects like Science, Mathematics, English, and Social Science. These components aim to enhance students' practical understanding, application skills, research abilities, and overall cognitive development.
