Spring 2 – Could you be the next CSI investigator? – Changing materials
This half term the children will understand that some materials dissolve in a liquid to form a solution> They will use their knowledge of solids, liquids and gases to decide how mixtures might be separated, including through filtering, sieving and evaporating. The children will discover that dissolving, mixing and changes of state are reversible changes. They will explain that some changes form new materials and this change is not usually reversible, including changes with burning and action of acid on bicarbonate of soda.
They will work scientifically to:
- Plan different types of enquiry to answer questions
- Control variables where necessary
- Measure with increasing accuracy and precision using a range of equipment
- Record data and results of increasing complexity using scientific diagrams, labels, keys, tables and graphs
- Use test results to make predictions and set up further tests
- Report & present findings, including conclusions & explanations in results
- Identify scientific evidence used to support or refute ideas or arguments
Spring 1 – Could you be the next CSI investigator? – Properties of materials
The children will compare and group materials based on their evidence from comparative and fair tests including their hardness, solubility, transparency, conductivity (electrical and thermal) and response to magnets
Autumn 2 – Can you feel the force? – Forces
This half term we will explain that unsupported objects fall towards Earth because of the force of gravity acting between the Earth and the falling object. We will identify the effects of air and water resistance and friction, that act between moving surfaces and we will begin to understand that force and motion can be transferred through devices such as gears, pulleys and levers.
Autumn 1 – Will We Ever Send Another Human To The Moon? – Earth and Space
This half term we will discover how the planets in our solar system move in relation to the Sun and how the Moon moves relative to the Earth. We will describe the Moon, Sun and Earth as approximately spherical bodies and use the idea of the Earth’s rotation to explain how night turns into day.
