Who doesn't love science experiment?! It's such a great way to teach the scientific process. Students are always engaged and learn quickly about hypotheses, making important observations, and drawing conclusions. Sink or Float I always use this experiment to introduce the scientific method. It is simple, quick, and to the point. After introducing and discussing the scientific method, I practice this experiment. Students ask questions, make a hypothesis about which objects will float, they design an experiment, act the experiment out, and draw conclusions. All of these steps can be found in these Science Journals. You can grab them by clicking here or by clicking any of the pictures. Students begin with different objects from around the classroom. Be sure to pick some that will sin and some that will float. Pom poms and sticky notes are good objects that float. I also used a counting bear and an eraser. Students then fill a cup with water and drop each object in. They will record their observations and decide if their hypotheses were correct. Stomach Acid Experiment A colleague had told me about this experiment to show how stomach acid breaks down food during the digestion process. It sounded so cool so I just had to try it! It was perfect timing while we were studying the digestive system. The experiment is simple: Get fruit (frozen or fresh), lemon juice (or lime), and baggies. Put the fruit in a baggie and soak in lemon juice. And that's it. The acid in the lemon acts as stomach acid would and begins to break down the fruit (or food) that is in your stomach.

Summary of the celery experiment: you put celery stalks in water with food coloring and the color travels up the stem into the leaves and changes colors. Students start by making a hypothesis, or prediction, about what will happen. They continue to plan and carry out an experiment (with your help of course!) Students love to write down their observations each day and see the progression of the food coloring traveling up the celery. This is a great experiment to do while studying parts of a plant. It amazes students to see the celery changing to the color of the water.It is a great way to show how stems bring water to the leaves of plants.
