Sink and Float - Experiments

The hands-on experiments in this resource, allow students to observe which objects sink or float in water.
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?
