Grade 6 Science Quiz: The Human Body Systems (15 Marks)

Learning Objectives

• Put the levels of organization in order — cell, tissue, organ, organ system, organism — and give an example of each.
• Name the 6 main body systems (skeletal, muscular, circulatory, respiratory, digestive, nervous) and match 16 organs and parts to the correct system.
• Describe the job of each body system in one sentence.
• Label diagrams of the digestive, respiratory and skeletal systems.
• Explain how muscles work in pairs, and how several systems work together when we exercise.
• Measure heart rate, record results in a table and bar chart, and explain why exercise changes it.

How to Use This Resource

• Use at the end of Lesson 2 or at the start of the review lesson. Students work alone for about 12 minutes. Mark with the answer key (1 mark per answer).

Classroom Activity Ideas

• Peer-mark Part A with the system cards on the board.
• Students who score 10 or less play the Which System? mode of the game before the test.

Differentiation

Support: Give a word bank for every labeling task and the sentence frames "The ___ is part of the ___ system. Its job is to ___." Let students answer the Which System? tasks with the organ cards in their hands. In the investigation, pair a stronger reader with a weaker one; any student can be the timekeeper or record data instead of exercising.

Extension: Add the excretory system (kidneys, bladder) and the idea of alveoli (tiny air sacs). Students design a fair test — "Does the type of exercise change the heart rate?" — and explain one way the model lung is different from real lungs.

Assessment

1 mark per answer, 15 marks in total. Score bands on the key: 14–15 Excellent, 11–13 Good, 8–10 Developing, 0–7 Needs Practice, with the slides to reteach.

Teacher Tips

Science words are long and new for EFL learners, so teach them as word families and link them to the body: "digest → digestion → digestive" while students rub their stomach, "breathe → respiratory" while they breathe in, "circle → circulate → circulatory" while they trace a circle over the heart. Keep the same gesture for each system in every lesson. Also watch for two common mix-ups: the spine (skeletal system) and the spinal cord (nervous system), and "blue veins" — blood is always red; blue is only a diagram color.
