# Cells and Systems Word Search

In Grade 8 science, you explore how living things are organized and how their parts work together. You investigate cells as the basic units of life ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)), examine how materials move in and out of cells through diffusion ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)), and learn about major body systems like respiration, circulation, digestion and excretion ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)). This word search covers key vocabulary from cells and body systems that you will encounter as you study how organisms function and respond to their environment.

## How to play

- Find each word in the grid. Words can run horizontally (left to right), vertically (top to bottom), or diagonally (in any direction).
- Circle or highlight each word as you find it.
- Some letters are used by more than one word, so look carefully at where words intersect.

## Words to find

- CIRCULATION
- DIFFUSION
- DIGESTION
- EXCRETION
- MEMBRANE
- RESPIRATION
- STIMULUS
- STRUCTURE
