This is a thoroughly differentiated GSCE chemistry lesson on alcohols for the 2016 GCSE chemistry specification. It forms part of the AQA organic chemistry scheme of work, topic 4.7. The lesson starts with students recapping prior learning on molecular formulae. Students are then introduced to the idea that the substance in alcohol is ethanol and that there are 2 main ways of making ethanol. They write word and symbol equations for these 2 methods. More able students draw the displayed formula and dot and cross diagram of ethanol (2016 specification requirement) whilst weaker students complete the equations activity. Students then compare the advantages and disadvantages of the two methods of making ethanol. The lesson concludes with an exam question plenary. Please rate this resource and leave feedback.
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 GCSE chemistry tarsia for revision of calculating relative formula mass. 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: relative atomic mass of atoms and isotopes (isotopes are limited to isotopes of oxygen and hydrogen) and relative formula mass of different compounds. The 'fjsw' file can be opened and modified with tarsia software. The software is free to download but there is not currently a version for Mac computers.
This is a fun GCSE Chemistry tarsia for revision of balancing equations. There are 16 triangles with 18 pairs of questions and answers that make an equilateral triangle. 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: reaction with oxygen, why we need to balance equations, a variety of balanced and unbalanced equations and number of atoms. The 'fjsw' file can be opened and modified with tarsia software. The software is free to download but there is not currently a version for Mac computers.
This is a Senior High School Chemistry lesson that covers the ideal gas law.

This is a Senior High School Chemistry lesson on constructing Born Haber cycles in order to calculate lattice enthalpy for ionic compounds. Students do not calculate lattice enthalpies in this lesson but rather consider using a diamond nine how various factors affect how exothermic the lattice enthalpy value is. I suggest printing the diamond nine on slide 23 and using it as a kinesthetic activity. Please rate this resource and leave feedback
This is a Senior High School Chemistry infrared spectroscopy. Expected prior learning is functional groups and how to draw organic molecules such as carboxylic acids. Students could write on the laminated sheets using whiteboard pens. The lesson provides extensive differentiation. The IR data used is from the NIST Chemistry WebBook. Both of these resources are referenced at the beginning of the lesson. A data sheet needs to be provided as this is a lesson that uses the Chemistry data book provided by the exam board.
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 lesson on entropy for Senior High School Chemistry that has been thoroughly planned and resourced. The lesson starts by getting students to classify reactions as endothermic or exothermic. This is required knowledge so please read through these before the lesson and make sure that students have covered this content. This starter activity could be printed and laminated to be used as a card sort. The concept of entropy is introduced along with the first and second laws of thermodynamics. A stack of Jenga bricks or a stack of cards could be used to illustrate that disorder is a more likely arrangement (gases) than order (solid). The custard powder combustion demo is used to illustrate that entropy changes in the system help predict whether a reaction is spontaneous (whether it happens). Details of how to carry this out can be found online at the UK Royal Society of Chemistry wiki and other websites. Students then are introduced to the three formulae needed and complete a worksheet that I have created where they calculate entropy of a system, entropy of the surroundings and total entropy. This is used to predict whether the reactions happen (i.e. whether there is a positive value). Note that balanced equations have not been provided and students at this level should be capable of writing these and sharing them with the class. Markschemes are provided for the entropy calculations. The lesson ends with a comparison of the importance of entropy and enthalpy. Please rate this resource and leave feedback.
This is a lesson for Senior High School 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 is a thoroughly planned lesson on the production of ethanol by fermentation of glucose and hydration of ethene. It has differentiated resources and a variety of activities and exam question plenaries to check student understanding. There is an optional production of ethanol practical that could be included in this lesson or as a separate lesson. Students start by recalling the formulae for different substances then learn the symbol equations for the two methods of ethanol production. They then carry out a literacy activity where they sort the advantages and disadvantages of each method of ethanol production. The lesson concludes with an exam question plenary. The practical could be included before comparing the advantages and disadvantages of hydration versus fermentation.
This is a Senior High School Chemistry lesson on advanced titration calculations for a very able class. It walks students through the steps in carrying out a back titration for weakly soluble bases.
This is an independent learning lesson on alloys for High School Chemistry. It is designed to promote independent learning and higher level thinking through role play, designing an aeroplane and justifying the choice of metals used by using data from a data table. The lesson starts by getting students to think about what three properties metals used to make the worlds fastest jet engined plane (SR-71 Blackbird) would need. Students could be shown a short video from YouTube to prompt their thinking and write their answers on post-it notes. They they then discuss what alloys are and could be asked identify the alloys in the metal trump cards pack (this would need to be printed in advance). They are then introduced to the 4 person role play task where they design an aeroplane. Limit their on this task to around 20 minutes. At the end they could either present their work or answer the 6 mark exam question at the end of the lesson. There is a student-friendly marking grid provided. The lesson menu is available for weaker students. Please look carefully at each of the resources provided before the lesson and decide which ones would best suit your group and length of lesson.
