In a playful way they will become familiar with making predictions, observations, identifying, sorting, reasoning, gathering data, comparing and evaluating. This resource includes: A clear explanation (with examples) of how to use this resource Two posters for your classroom to help visualize the concepts of sinking and floating. Various recording sheets to record the experiments (differentiated): Sink or Float? (Cut and paste pictures to record the result after testing) Test & Sort (Testing, identifying and recording results) Make a Prediction (Creating a visual record of their prediction, and observation. Evaluate prediction in comparison to result with a smiley to enhance future predictions) Predict & Test (Data handling: create a more abstract record of prediction and observation) Step by step instruction of how to conduct the following experiments (incl. photos + explanation of why it works this way): Experiment: Do eggs sink or float? Experiment: Does an orange sink or float?
