Biodegradability??

Biodegradable is the topic- grade 3/4- By Tessa Mckenzie
What we did is- we collect a coffee filter, a string,an apple core,bread,plastic bag, metal foil . We put them in a bucket of dirt and made sure they were covered.We check up on them once a month to see if they are decompossing. We were put into groups and brainstormed (think pair shared)what would decompose. My groups prediction was that the apple core would decompose
So far the only ones that are changing (decompossing) are bread and the apple core. I do not think that anything else is decomposing because it did not change so far. Because we narrowed down the bread and the apple core those are the two finalists.
We will check in later to see the final results.
