#### Atomic Structure & Nuclear Radiation

(0)
Lesson recapping atomic structure and isotopes and introducing nuclear radiation. The power point forms the lesson presentation and includes links to the youtube videos that the video worksheets are designed to be completed with and answers are included on the following slides. The lesson would be well accompanied by a set of questions from your school’s textbook or an exam question from a past paper. Structure of the lesson: -Starter recapping atomic structure (also a suggested homework) -Content on the structure of the atom - relative sizes of nulceus and atom -Recap activity (video worksheet) on isotopes Introduction to nuclear decay and why it happens Video worksheet activity Introduction to the three main types of nuclear radiation (to be discussed in more detail in a following lesson)

#### Current around series and parallel circuits

(0)
This resource is ideal for pupils struggling to understand how current is the same at all points in series circuits and shared between branches in parallel circuits. Each power point is a set of repeated slides containing a circuit diagram and imposed on this are 4 “electrons” (image of a toy electron) that move around the circuit with each change of slide. The students can clearly see that for the series circuit all 4 electrons pass each point whereas in the parallel circuit they split, with 2 passing through each branch. The video could also be used to guide pupils to deduce how current varies in each type of circuit if they don’t have access to electric circuits and ammeters.

#### Pollination, Fertilisation and Germination - KS3 worksheet

(0)
Double sided worksheet ideal for printing on A3. Pupils can either use a textbook or knowledge organiser alongside the worksheet to form an information hunt or as a summery activity where pupils review and apply their learning of pollination and germination.

#### Physical Changes vs Chemical Reactions

(0)
Lesson for the differences between physical changes and chemical reactions. The lesson starts with a quiz where pupils have to state whether they think a change is physical or chemical and answers can be indicated by either red and green coloured cards or on whiteboards. There main activity is the combination of content delivery from the presentation accompanied by the student worksheet. Answers are embedded on slides. Plenary reflects on progress made by answering questions, colour coded by difficulty.

#### Half-Life Lesson

(0)
Lesson power point and activity on half-life. The power point has a starter that recaps writing decay equations. There is then a brief recap of nuclear decay before explaining half-life and activity. Pupils would then complete the worksheet of practice questions for calculating half-life and the answers are provided on the slides. This would then be followed by past paper questions that introduce finding half-life from a graph.
