A video showing what different Leaf Perservation Methods look like (including how to preserve leaves using a Glycerin Bath). The results are inconclusive. Generally yellow and green leaves perserve better than red leaves. We compare laminating, pressing of leaves, glycerin bath and coating in PVA glue.

Turn this into a S.T.E.M. activity by predicting the outcomes with the kids and investigating what happens with colours and their chemical make up.
