Ratios are super important for projects about the environment. They make Year 7 Math lessons fun and useful. Ratios help us understand real-world problems, like how to compare different amounts related to the environment.

Examples of Using Ratios in Environmental Projects:

1. Waste Comparison:

   • Students can gather different types of waste from their homes, like plastic, food scraps, and paper. They can then create ratios based on what they find. For example, if a student collects 3 bags of plastic waste and 2 bags of organic waste, they could write this as a ratio of 3:2.

2. Water Consumption:

   • Students can keep track of how much water they use in a week. They can compare this amount with what the average household uses to find a ratio. If one house uses 200 liters of water and another house uses 100 liters, the ratio would be 200:100. This can be simplified to 2:1.

3. Plant Growth:

   • Students can watch two types of plants to see how they grow over time. If Plant A grows 6 cm in 3 days and Plant B grows 9 cm in the same time, they can talk about the growth ratio. This would be 6:9, which can be simplified to 2:3.

These activities not only help students learn about ratios but also make them feel responsible for the environment. It’s pretty cool to see math used in real life!
