## Activity Introduction

Activity details: Students learn the definition of green space through exploring a map of their neighbourhood or area. Students will determine whether the area that they live in has enough green space and will design a new town that is greener.

Key lessons and understandings of activity:
Students use satellite images to estimate the percentage or ratio of green space in their local area. They make judgments about what is adequate green space.

Activity outline

Begin this activity by asking your students to define the term ‘green space'. What do they think it means? Does it refer only to public parks and gardens or should it include private gardens as well? The Oxford Dictionary defines green space as: 'an area of grass, trees, or other vegetation set apart for recreational or aesthetic purposes in an otherwise urban environment'.

Using Google Earth, ask students to look up their neighbourhood or local area and find out how much green space there is around their school, their home and in the suburb or town that they live.

### Challenge 1

Students have to estimate what percentage or ratio of the local area is green space. They are to attempt this just once coming up with their own solutions. (E.g., create a print out of the local area, d

### Instructions:

Step 2: Your job is to estimate what percentage or ratio of the local area is green space. How will you do this?

Step 3: Once you have made your estimates, compare the estimates and the methods other students tried. Answer the questions below.

Questions:

1. Did all students come up with the same estimates?

2. What was your method of estimating the green space?

3. Do you think the amount of green space changed over the last 100 years? If so why?

4. How could you had more green spaces to the area?
