observations can be used as a basis for posing questions to identify patterns and relationships, and to predict the outcomes of investigations

• making predictions based on previous observations of potential changes about the mass of ice in a sealed container as the ice melts, such as predicting how quickly ice will melt at different ambient temperatures or predicting whether the mass of ice in the sealed container will change when the ice has melted
• predicting which objects will reach the highest temperature when they are heated
• predicting the effect on food chains when living things are removed from or die out in an area, based on current observations and discussion
• posing questions about why some materials are used more often than others for particular products
• posing questions about substances that are difficult to classify as solids, liquids or gases, such as toothpaste, slime, foam and hair gel
