This is a fun expanding brackets fun High School Mathematics tarsia. There are 16 triangles with 18 pairs of questions and answers that make an equilateral triangle shape.

These are thoroughly differentiated resources designed for an AS level chemistry lesson on reduction of carbonyl compounds. Objectives are framed as learning questions and graded C to A. There are clear AFL plenaries using mark schemes. There is a graded Who Wants to be a Millionaire quiz for an end plenary. The starter is an engaging scents demo using butanal (pleasant) and butanoic acid (rancid butter). Pace and student effort is the key to delivering an outstanding lesson using these resources. Mark schemes can be printed. Please rate this resource and leave feedback.

This is a lesson for A level chemistry where students are introduced to Hess Law through the topic of vectors that they would have learned at GCSE. The lesson starts with a GCSE recap on vectors then moves into discussing that some enthalpy changes reactions cannot be calculated or are difficult to calculate and so alternative reactions are used. Students then learn that the exams require them to use a few types of enthalpy change to calculate an unknown enthalpy change. These are bond enthalpies, enthalpy of combustion and enthalpy of formation. Students are told how to draw the arrows. Please note that this a very difficult topic for all students and do not assume that the lesson can be rushed for the brightest students. Please rate this resource and leave feedback.

This is is an introductory lesson on atomic structure for High School Chemistry that begins with a fun film characters elements starter. There is then a discussion on how elements are made in supernovae. Students then consider rules for naming compounds and how to write formulae. They then then write the formulae for 12 substances. The challenge is to write empirical formulae. The lesson concludes with a consideration of how some of the chemicals are harmful to fish such as Nemo. Titanium dioxide in suntan cream causes water and oxygen in seawater to react to form hydrogen peroxide that is toixc to fish. Answers are included.

This is a lesson on entropy for A level 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 RSC 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 chemistry lesson designed for the 2016 specification for the exam board AQA and topic 4.7 organic chemistry. This lesson covers content that is new to GCSE and was previously covered only in A level chemistry. The challenge with planning this is that students are greatly limited by what they learn at GCSE. For example they do not learn about terms such as 'arene', 'carbonyl', 'amine' and do not recognise that (CH2)6 = CH2CH2CH2CH2CH2CH2. The lesson recaps addition polymers then introduces condensation polymers as polymers that are found in nature as well being man-made. There is an exam of an easier A level past paper question on identifying the monomers. Most A level questions on this topic are far too challenging to be put into the 2016 GCSE specification. Students then compare the environmental impact of natural vs manmade polymers (RSC paper cups activity - link has been provided) and answer a 6 mark exam question. They then peer mark the exam question using a student friendly marking grid. There is the option of carrying out a bioplastics practical that I have created - note that the bioplastics take at least 2 days to dry out. Please rate these resources and leave feedback.

This is a comprehensive lesson on atomic theory designed for the AQA GCSE specification. The starter is a recap crossword on atomic structure (assumed knowledge). The lesson then takes a chronological journey from the ancient Greeks to alchemy to the Enlightenment and then the 1800s/ early 1900s where Rutherford et al developed the modern model of the atom. The theory activity works really well with all ability and shows that there is little or no evidence to support the early cubic model but there lots of evidence to support the GCSE Bohr model. The lesson finishes with a 6 mark question that is peer marked using a marking grid. Please rate this resource and leave feedback.

This lesson forms part of the chemistry GCSE atomic structure scheme of work for the new 2016 AQA specification. The starter is a fun kinsthetic activity where students put element cards into groups. These cards are available to buy from Royal Society for Chemistry. A link is included on the slide. Alternatively students could make a pack of element fact cards for homework and bring them to lesson for the starter activity. Students are then introduced to Dobereiner and Newlands. They watch a 3 minute YouTube video about Mendeleev and answer the questions provided. Students then consider that Mendeleev missed group 8/0 elements and swapped iodine / tellurium so that the group 7 elements are all non-metals (i.e. why de not always put elements in order of increasing atomic weight). There is an activity where students consider the good and bad things about each scientists methodology and write an explanation for why we now use Mendeleevs table. Finally there is an exam question plenary. Please rate this resource and leave feedback.
