Graph or Diagram to support our learning - Worksheet - Year 4

For Year 4 students, understanding the separation of mixtures and the changes of state in solids, liquids, and gases is a fundamental aspect of their science curriculum. A worksheet designed to support their learning might include graphs or diagrams that visually explain these scientific concepts. The worksheet poses questions such as "How do we go about separating sand, salt, and water?" and "How do some solids, liquids, and gases change state?" These questions encourage students to think about the processes involved in separation techniques and the transition between different states of matter.

When discussing the separation of sand, salt, and water, a diagram might illustrate the steps of filtration and evaporation. Filtration would show how sand can be removed from the mixture by passing the solution through a filter, leaving the sand behind, while the salt and water pass through. Evaporation would then be depicted as the process of heating the saltwater solution until the water turns into vapour and leaves behind the salt. Another part of the worksheet could focus on the changes of state, using a graph or diagram to show how solids melt into liquids, liquids evaporate into gases, and gases condense back into liquids. These visual aids are crucial in helping Year 4 students grasp these scientific concepts more effectively.
