Some of our stories from lockdown.
Since September, we have been learning about the damage that plastic pollution is doing to the environment, especially the world's oceans and their wildlife.
We wanted to know which type of bag is the most environmentally friendly. That is the type that will biodegrade or decompose the quickest in the environment. We are running a scientific experiment to find out.
We put four different types of bag into four flower pots and buried the bags in soil. We will wait for 10 days, then empty them out to check what has happened to the bags. Then we will check every month to see which bag is the first to decompose. The pots were left outside exposed to the rain, sun and wind.
Results so far.
After 5 weeks we tipped out the soil and inspected the bags. The paper bag had started to decompose and fall apart, the two compostable bags had both deformed but were still intact. The plastic bag had not changed.
After 3 months
The 4 bags remained buried soil until the end of term. In December, after being buried for 3 months we tipped out the soil again to inspect the bags. The paper bag had completely decomposed. The two compostable bags were showing signs of decay but the plastic bag appeared to be unchanged.
