This resource is an introduction to electrolysis for a lower ability group. It firstly introduces students to some key terms in electrolysis and then what this process entails.

For this worksheet, students complete particle diagrams as a liquid is heated then cooled. Students also include a description of each diagram. There are two versions of this worksheet based on the ability of students. The mark scheme is also included.

This lesson draws on the familiar concept of how pole in magnets behave when their magnetic fields interact before relating this to the charges of subatomic particles and their behavior when in contact. Students then compare the Plum pudding model and nuclear model of the atom before getting an overview of the alpha particle scattering experiment. The lesson then closes with students understanding what the evidence from this experiment reveals about the structure of the atom and nucleus.

Students observe simple experiments to separate different mixtures, where the best/ most appropriate technique(s) is chosen using the apparatus provided. A mark scheme is also included and along with referenced video links of experiments.
