This is a lesson for A level chemistry on electrochemical cells. It starts with students constructing a fruit cell and combing four of these cells to make a battery that powers a light bulb . These are made from a whole lemon, piece of clean copper, piece of clean zinc, electrical wires, crocodile clips and light bulb. This could be shown as a demo if there is not much time. Students offer explanations as to how this works. They are introduced to the theory behind how batteries work, what a half cell is and notation for writing half cells and E-cell. The hydrogen / H+ / platinum reference electrode is then introduced as a standard that is used to compare the voltage different half cells. Reinforce the idea that platinum is used because it a very unreactive electrical conductor. Students then use the electrode potentials table (go through this) to write the voltage and reactions for different combinations of half cells. This could be set as homework instead. The lesson finishes with an exam question plenary. Please rate this resource and leave feedback.

This GCSE chemistry lesson has been designed for the 2016 specification for AQA. The lesson begins with a recap of addition and condensation polymers. It then moves on to covering the key biochemical points that students need to know for GCSE chemistry and deliberately leaves out GCSE biology content. The lesson then moves on to students comparing the strength of their own bioplastics from the previous lesson with nylon. If students make the bioplastics in this lesson then allow at least 2 days for the bioplastic to dry before testing it. The lesson concludes with students analysing their data.

This GCSE chemistry lesson on transitions metals has been designed to meet the AQA 2016 specification and is part of the 4.1 atomic structure scheme of work. The lesson starts with a recap of the order of the reactivity series and asks students to put lithium and rubidium in this series using prior knowledge from reactions of the alkali metals (required prior learning). Students are then introduced to the key question for the lesson - this is revisited at the end. Students then watch a 4 minute video about the SR71 Blackbird (YouTube link is on the slide). This is the worlds fastest jet powered plane that is no longer used by the American military and flew at speeds of up to mach 3.2. Students then write on post it notes three properties that metals used to make this plane should have. If they struggle they could choose 3 properties from the data sheet. These are put on the whiteboard with their names on the notes and one student comes to the front to read out 3 post it notes. The teacher could compare the reactivity of iron filings and potassium with water (RSC practical link is included and can also be found online). Students then answer a few questions that require analysis of the data sheet. This is an important exam skill. They then use these answers to write an extended 6 mark question and then peer mark this using the student friendly marking grid. There is an optional 4 person role play task included in a separate PowerPoint for longer lessons or classes that are good with group work. The lesson menu can be printed and used with weaker students. Please rate this resource and leave feedback.

This is a lesson for Senior High School Chemistry on fuel cells. It begins with getting students to consider whether hydrogen would be a good source of energy to power cars for the future. Required learning from previous lessons is electrode potentials and half cells. The hydrogen balloon demo could be shown at the start to get students to appreciate that a lot of energy is released in a short amount of time from a small amount of fuel. Hydrogen produces the most amount of energy per gram for any chemical fuel. Students then draw a diagram to show how the standard electrode potential of an oxygen half cell could be determined - i.e. use a H+ reference electrode in one beaker and connect using a salt bridge to another beaker with O2- ions and O2 gas being bubbled through and using platinum as the electrode. Students then learn that O2 gas is reduced in the presence of H2O (i.e. bubbled through water) to OH- ions not O2- ions. This forms the basis of the hydrogen fuel cell where oxygen is bubbled in to one beaker with a platinum (or carbon) electrode, hydrogen is bubbled into another beaker with a platinum (or carbon) electrode and a salt bridge is attached between the beakers. Students could carry out this practical in pairs by using balloons filled with hydrogen and oxygen and allowing the gases to escape under water in the 250ml beakers. Filter paper soaked in sodium hydroxide could act as the salt bridge. Students then compare different types of fuel cell and write overall equations. There is a 5 mark exam question that can be used as an end of lesson plenary or homework. Please rate this resource and leave feedback.

This is a comprehensive set of differentiated lesson resources that cover polar covalent bonding. Within the lesson are Pauling electronegativity values that can be used to determine the extent of covalent bonding between two atoms. The lesson begins with a recap of ionic and covalent bonding definitions from GCSE. There is then a discussion on electronegativity differences between atoms. Students then carry out the kinesthetic task where put different comments about bonding on a scale from pure covalent to pure ionic. This scale can be printed on A3 paper. The comments can be printed on A4 paper. There is then a peer editing question task and plenary exam questions with markschemes. Please rate this resource and leave feedback.

This is a lesson written for the AQA 2016 chemistry specification that covers the following: the three types of bonding, the reaction of sodium chlorine demo, how to work out the charge on an ion by comparing the number of protons and electrons, why ions form (stable octet) and how to work out the formula on an ionic compound using a method that I have created called 'WiSC'. The lesson concludes with a differentiated plenary. Please take the time to carefully look through this presentation before the lesson as there a lot of animations that carefully sequence different concepts.

This forms part of the chemistry scheme of work for the new 2016 specification. The homework task is set in advance so that students can mark their homework as a starter activity. There is an optional starter activity to show students as they walk in which is a recap of what atoms and elements are. The video is the worlds smallest video created by IBM. It shows atoms of an element moving around - the key point being that atoms of a particular element are identical. The first activity looks at understanding how to work out the number of subatomic particles. Students are then introduced to the concept of isotopes. The next activity looks at electron shells the more able students are introduced to ions. The lesson finishes with an exam question plenary. Please rate this resource and leave feedback.

This is a fun yet challenging High School Chemistry tarsia for revision of the paper chromatography. There are 16 triangles with 18 pairs of questions and answers that make a parallelogram. I suggest that the A4 tarsia is printed on card and then the outline is cut out. Students can then quickly cut out the individual triangles. Included are the following topics: Rf value, adsorb, solvent, soluble and uses of chromatography. The 'fjsw' file can be opened and modified with tarsia software. The tarsia software is free to download but there is not currently a version for Mac computers.
