Periodic table metals cover work

Periodic table metals cover work

(0)
Worksheet on using data about elements and spotting trends. Broadly related to metals and non-metals but more about data handling and analysis. Mathematical skills - graph drawing, calculating density and volume. Suitable for use as a half hour cover task.
Carbon NMR problems

Carbon NMR problems

(0)
This is a workbook with a variety of problems related to C-NMR (no proton NMR in this resource). It can be printed out and given to students to work through. All problems have solutions included on a separate page to the problems so that you can print these separately if you want to. Contains worksheets on: Counting carbon environments Matching structures to spectra Predicting spectra Interpreting simple spectra Integrated problems where students must use C-NMR, IR and mass spec, as well as information about chemical reactions, to deduce the structures of molecules (4 long problems - I print these on A3 and give them to my students to do in groups after we have covered C-NMR but before we start H-NMR. It usually takes them about an hour to get all four)
Structure and bonding long answer questions
sasioc

Structure and bonding long answer questions

(0)
Twenty long answer questions for Edexcel Topic 2: Structure and Bonding. Includes IMFs. I put students into groups of three and give each group one or two questions. Each group writes three answers for their question: a poor answer, a middling answer and a model answer. Each group gets a different question to do this for. They then go round and look at other groups’ work and try to rank and, if possible, mark their three answers, before being set some or all of the remaining questions for homework. This can lead to a nice discussion about how to structure answers and what students looked for when deciding which answer was the best.
Moles Sudoku
sasioc

Moles Sudoku

(0)
Tougher moles questions for able GCSE or iGCSE students. Also suitable for Year 12. Answering the questions correctly should enable students to fill in the Sudoku - if the Sudoku doesn’t work they have got an answer wrong. This means that students can check their work to some extent. Questions are colour-coded according to difficulty and can be solved in any order. Some spaces have more than one question listed. In these cases all questions give the same answer so students can mix and match, or try the easier question before seeing if they get the same answer from the tougher one. Good as a revision activity. I have previously printed it on A3 and got students to work together on it.
Element, compound or mixture?
sasioc

Element, compound or mixture?

(0)
A quick worksheet in which pupils look at diagrams and decide whether they are looking at an element, compound or mixture. Most of the diagrams are of substances that will be familiar to pupils, eg. air.\n\nThis is a good starter or plenary or alternatively an activity that you can use when introducing elements (pupils label 'element' or 'non-element') and then return to later.
Oxidation Numbers Game - Redox
sasioc

Oxidation Numbers Game - Redox

(0)
Print two or more copies with two slides per page of A4 and trim to give A5 cards. Each copy should ideally be on a different colour of paper. I have laminated two sets of these and use them every year. The numbers are arranged in a number line. Each team of students gets a stack of species cards and must race to place them all on the number line at the place that shows the correct oxidation number. The clock stops when the fastest team finishes and whichever team has the most right answers at this point wins. I usually only let one student from each team go up at once, like a relay, although they can call out help to each other. I also usually get teams to mark other teams’ work and adjudicate if they think another team has got one wrong. I’ve included a “how-to” guide for working out oxidation number, that you could allow students to use if you wished.
Introduction to Equilibrium I

Introduction to Equilibrium I

Print on A3 or A4. Ask students to annotate the page, showing how the different concepts are linked, to get them thinking about the topic.
Ethanol Handout

Ethanol Handout

Fill in the blanks style handout for topic: Ethanol (Edexcel iGCSE Chemistry until 2017)
Elements Cards

Elements Cards

(1)
Each card contains information about an element. They can be used in a wide variety of ways. Recently, I gave them to an able year 8 class and asked pupils to sort the elements into groups based on their properties to introduce the idea of the Periodic Table. I have also given the cards to pupils and asked them to tell me what the properties of metals and non-metals are.
Alkanes handout and quiz

Alkanes handout and quiz

(0)
Fill in the blanks style handout for a lesson on the Alkanes topic, covering what an alkane is, displayed formulae, naming alkanes and combustion of alkanes. Powerpoint quiz suitable for use with mini whiteboards as either an individual or a group activity.
Alkenes handout and naming quiz

Alkenes handout and naming quiz

(0)
Handout on alkenes topic, covering definition of an alkene, naming alkenes and simple addition reactions of alkenes. PowerPoint quiz on naming alkenes suitable for use with mini whiteboards or as a group “pub quiz” activity.

Fill in the blanks style handouts for alkanes, alkenes, cracking and ethanol. Whiteboard quizzes on alkanes and naming alkenes Worksheet on crude oil, alkanes and alkenes Designed for Edexcel iGCSE
Moles revision questions

Moles revision questions

(0)
A set of confidence interval questions (activity described on sheet) for moles calculations. Includes Finding Mr Molecular + empirical formulae Reacting masses Writing formulae for ionic compounds I use this as a small group activity. I print it on A3 and get students to work together on the problems, assigning each one a score depending on how sure they are that they’ve got it right. Answers included.
Metallic Bonding Key Words Plenary

Metallic Bonding Key Words Plenary

(0)
A quick matching activity to be used as a starter or plenary following initial learning about metallic bonding. Pupils match key words to their definitions. A couple of words have no definitions listed and pupils must write their own.
Chemical and Physical Change Cards

Chemical and Physical Change Cards

(4)
I used these when I covered chemical and physical changes. The cards are very versatile: I've had able pupils sort cards into what they think physical and chemical changes are and then explain their criteria, I&'ve given pupils a list of which is which and asked them to produce a set of criteria for working it out and I&';ve given these to pupils who have already covered physical and chemical changes and simply asked them to sort the cards into two groups. There are a few slightly tricky examples in there that can lead on to practical work or promote discussion, eg. hydration of cobalt chloride
