We were busy today building beaches with wet sand to test the effects of constant ocean waves on the shoreline. New vocab word: EROSION!! / Estuvimos muy ocupados hoy contruyendo unas playas con arena mojada para investigar los efectos de olas de mar en la costa. Nueva palabra de vocabulario: ¡¡EROSIÓN!!

Our second round of the experiment required us to build sand dunes on our beach and insert toothpicks to represent plant roots. We then tested the effects of ocean waves again. Final conclusion: Dunes and plant roots help beaches not to erode so quickly! / La segunda etapa del experimento nos requieró construir unas dunas de arena y colocar palitos de madera para representar raízes de unas plantas. Luego, investigamos los efectos de las olas del mar una vez más. Conclusión final: Las dunas y las raízes funcionan para evitar los efectos de erosión.
