A Successful Science Experiment.
What a busy term it has been and it's already the end of Week 5. Team Moana have been really busy getting their heads around our science unit based on the classification of life forms. We learned that living things all carry out seven processes and that you can remember them by using the acronym MRS GREN. This stands for Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition. We decided to do an experiment to see if plants really do respire. The scientists say that plants take carbon dioxide from the air, use it inside their cells to grow, and release some oxygen back into the air as they don't need all of it. We tested this hypothesis by putting leaves in warm water for a few hours. If it was true, we should see little bubbles of oxygen forming on the surface of the leaves. It worked!!!! It was very cool!! Ariana took this very good photo using an iPad so now we have proof that our experiment worked. We don't know why the bubbles are only on...
