Aimed at mixed ability year 8 class Starter: Write a hypothesis for what students think will happen to the amount of a solute that can dissolve as temperature increases Main: Practical, have different water baths, see how much sodium bicarbonate dissolves at each temperature Record results on worksheet Differentiated worksheet higher or lower ability. Once completed practical evaluation and conclusion on each practical. Different tasks for higher and lower ability students

Aimed at a mixed ability year 9 class starter: Differentiated starter task from previous learning. Bronze = level 4 silver – level 6 gold = level 8  (to be gaining a level 8 answer needs to be really detailed) students have done this at KS3 Go through and green pen answers   Main Talk about safety for the practical, demo practical with distillation to get pure water Students carry out rock salt practical to get salt Answer questions when done, extension question available also Plenary 5 mins Identify the three processes we have learnt about today   Homework - differentiated Summary sheet on separation techniques

aimed at mixed ability year 9 class Starter Activity Differentiated Bronze/silver/gold questions from previous lesson Main – Think, pair, share – how big is an atom. Copy down the size of an atom and nucleus intho their books Copy key words need to be able to define ion and isoptope for level 4 Explain that atoms can lose or gain electrons. And what happens if they do. Students make notes on this, then go through a few examples. Students practice working out electron/proton/neutron for ions Extension task for students who finish Explain what an isotope is, do one worked example of finding proton/neutron numbers then their go at finding how many protons and neutrons are in carbon isotopes Exam practice if time Plenary Identify whether the pictures are atoms, ions or isotopes

Aimed at a mixed ability year 9 class Starter Activity Draw and label the atom – discuss that its changed over time Main – Watch video of history of the atom – try and list the scientists and their discoveries Use textbooks or ipads to research the history of the atom and fill in the timeline. Differentiated version, blank version for HA students and LA version with question prompts Extension fill in the gaps sheet Plenary Draw the current atom from memory and label it

Aimed at a mixed ability year 9 class Starter Activity Exam question starter – go through and green pen Main – Recap where to find the number of electrons an atom has, go through electronic structure rules. Do a few examples on the board Two worksheets – first worksheet students need to find out the number of protons, neutrons and electrons each element has, the second they need to draw the electronic structures Extension:  explain why sodium and lithium might react in a similar way Write a step by step guide for somebody to explain how you draw electronic structures Plenary Exam question plenary – spot mistakes in the electronic structures

Suitable for KS3 Includes Recall starter Element mixture or compound particle diagrams and task Mini demo or practical to show how we can separate mixtures Written task to explain how properties can help us separate mixture Peer assessment grid recall plenary

Suitable for year 7/8 Recall starter Followed by explaination and practice of the new keywords solute/solvent/solution Questions and tasks provided with answers mini practical to do with solubility, does it dissolve or not? Questions for follow up to the practical Recall plenary

A tutoring powerpoint I used does not include percentage yield. Comes with a key question document and exam questions. All answers to powerpoint included as animations or in the notes below

Two lessons, can be combined into one.

Lesson includes a practical to investigate how temperature affects solubility. Comes with an optional work sheet.
