Grade 5 Science Connections Worksheet
| # | Answer | Explanation |
|---|---|---|
| 1 | Both can perform tasks or actions. | Robots and human bodies can both move and do work, even though they do it in different ways. |
| 2 | b) respiratory system | The respiratory system brings oxygen into the body and helps remove carbon dioxide. |
| 3 | computer | A robot’s computer or controller gives instructions, similar to how the brain helps control the body. |
| 4 | 1-D, 2-B, 3-C, 4-A | Each body part has an important job that helps the body work properly. |
| 5 | An arm and hand | Robot arms often copy the movement of human arms and hands when lifting or holding objects. |
| 6 | True | Bones protect many important organs, including the skull protecting the brain and the ribs protecting the heart and lungs. |
| 7 | The body’s health, especially how the body is working overall; one possible answer is the immune system or general body health. | A temperature check helps people notice if something may be wrong in the body, such as a fever. Because this is Grade 5 and easy difficulty, accept 'general body health' as correct. |
| 8 | a) digestive system | The digestive system breaks down food and moves nutrients through the body. |
| 9 | To detect information from the environment, such as light, touch, or sound. | Sensors help robots notice what is happening around them, similar to how humans use their senses. |
| 10 | C, D, A, B | A robot first senses information, then sends it to the controller, receives a signal, and then acts. |
| 11 | Both help create movement. | Muscles move body parts, and motors move robot parts. |
| 12 | a) copies a human skill | Assistive machines and robots often help people do tasks or support a human skill. |
| 13 | The nervous system | The nervous system sends quick messages to help the body respond to danger. |
| 14 | Because mistakes could hurt patients or give wrong information. | In real life, hospital robots must be precise so they can safely help people. |
| 15 | b) energy source from food | Food gives the body energy, just as a battery gives power to a robot. |
| 16 | Sample answer: A robot could help a person walk if their legs are hurt, or remind a person to take medicine. | There are many correct answers as long as the robot is helping with a real body need. |
| 17 | The eyes and nervous system | The camera collects information like eyes do, and the controller uses that information like the nervous system. |
| 18 | False | Robots can copy or model different body parts and systems, such as arms, eyes, or even movement and control. |
| 19 | Sample answer: A robot could help guide students by giving directions or checking that hallways are clear. | Robots can be helpful by sharing information, guiding people, or helping keep order. |
| 20 | Sample answer: It could help lift heavy items and copy the muscles and arms. | Students should give a reasonable robot design and match it to a human body part or system. |
