In this lesson we will describe atoms using the nuclear model, including the charges and mass of the three subatomic particles. We will use the periodic table to calculate the number of protons, neutrons and electrons for any given element.

In this lesson we will describe the development of the atomic model, comparing the nuclear model with the plum pudding model and explaining how new evidence from the gold foil experiment led to a change in the atomic model.

In this lesson we will investigate a range of specialised animal cells and relate the function of the cell back to their structure.

In this lesson we will define diffusion, explain factors that affect diffusion and discuss examples of diffusion in the body.

In this lesson we will Identify variables to change, measure and control to investigate diffusion work safely in order to collect and record data to test the hypothesis. We will process the data to calculate a mean, accounting for anomalies, displaying data appropriately, including a table for results with units.

In this lesson we will define an isotope, compare isotopes based on information given and calculate RAM of isotopes given their abundance and give answers to a specified number of significant figures or decimal places.

In this lesson we will describe the composition of the air we breathe in and out, explain the results of an experiment to prove the differences and then collect, display and process data appropriately.

In this lesson we will understand key ideas about the life and work of Dr Fiona Wood.

In this lesson we will recall key terms, definitions and structures related to cells, tissues, organs and systems. We will describe ways in which cells, tissues and organs are specialised for function. Finally, we will explain adaptations in terms of diffusion.

In this lesson we will describe transverse and longitudinal waves in terms of amplitude, wavelength, period and frequency.

In this lesson we will describe how materials differ in terms of their properties, and describe how light behaves at the boundary of two media (reflection) using ray diagrams.
