Digestive System – Grade 7 Science Worksheets

Home >> 7th Grade Science Worksheets >> Digestive System

The Digestive System is one of the vital systems of all living beings. The food we eat gets converted to the much needed energy only due to our digestive system. All the organs of this system work in perfect synchronization to make sure that maximum nutrition is extracted from this food and passed on to our Circulatory System.

This Grade 7 Worksheet aims at strengthening a student’s Science concepts about the ‘Human Digestive System’.  Other than fill in the blanks and definitions, it also includes diagrammatical questions that makes it fun and interesting. This worksheet can be used by tutors as a ‘Diagnostic Assessment’ to plan and design a Grade 8 student’s future learning sessions on this topic.

It can also be used as an ‘End of Topic Test’ to assess a student’s assimilated knowledge about the topic.
