This is a chemistry lesson focused on properties of simple, giant ionic and giant covalent bonds. It will require a bit of teacher led input (there isn’t a powerpoint) but the lesson should be pretty straightforward, make sure you have access to water, salt and a power pack for a practical demo on conductivity.
Detailed notes for the A-Level Chemistry student on Enthalpy (32 A4 Pages). Can also be used by a teacher for refreshing their knowledge or to gain some examples to use with their students. These notes have been on the most part HAND WRITTEN and SCANNED IN, HOWEVER there are a few typed pages at the end.
-Enthalpy diagrams and interpretation
-Enthalpies of Combustion and Formation
-Enthalpy of Neutralisation
-Experimental Measurement of Enthalpy Changes (includes calculations, explanations of variations in results and a hand-drawn diagram
-Measuring enthalpy changes for reactions in solution (with method and worked calculation)
-Hess's Law and Calculation of Enthalpy (lots of examples and calculations and different methods of calculation using cycles)
-Average bond enthalpies
-Thermodynamic vs Kinetic Stability
-Suggested resources (links to videos and websites etc.)
A3 Poster Summary of Atomic Structure for A Level students - also probably useful for GCSE (Higher papers). Great to laminate and put around your classroom or science department. Enjoy!
-The Titration Technique (and associated calculations and definitions)
-Periodic Table, States of Matter and Bonding (with definitions)
-States of Matter
-Why water expands when cooled
-Notes expanded from the mind map
-Useful links to websites and videos
Complete with interview lesson plan, this lesson was originally developed for Section C1 of the now discontinued ‘Science A’ AQA Specification for Year 10 Core Exams, however this is still in the specification for the new 9-1 Chemistry (triple) exam, particularly higher tier.
• To explain how polymers are made from monomers and the difference between alkanes and alkenes.
Differentiated for learners:
All students will be able to recognise the primary difference between an alkene and an alkane and know the difference between a monomer and a polymer
Most students will be able to describe how a polymer is formed and how to show this using structural formulae
Some students will go even further and be able to express some of the complex environmental issues surrounding the production of polymers and how these can be resolved.
The lesson can be pulled off in as little as 50 minutes with good pace but has enough material for more. You will require the ‘coloured card’ method of using various coloured cards with letters on them (A, B, C or D) to match appropriately with the quiz questions. The sea of colours helps to quickly identify any students who don’t understand, and demonstrate to the observer that progress is being made.
This lesson is aimed for a double lesson, but can be amended as necessary.
Students recently completed a series of lessons on diabetes. This lesson is a required practical covering food tests. It will be written up in their lab books.This is ‘Required Practical 4’.
LOs: (We are learning …)
• How foods can be classified
• What a positive test looks like for each of the food types
• How to carry out qualitative tests to detect the presence of sugars (Benedict’s Test), starch (Iodine Test), proteins (Biuret Test) and lipids (Sudan III Test)
• To apply key terms in order to write up a scientific investigation; reducing sugars, glucose, starch, positive/negative test result, iodine, biuret, lipids
Ideally for this resource you should have access to Kerboodle. I have not included these worksheets for copyright reasons but you can access these through your school to obtain the differentiated practical sheets. Alternatively, you may use the standard AQA one in their official required practical booklet, freely downloadable on their website.
Credit for the methods and photos to CGP Books, from where the scanned images and answers were obtained.
This lesson is suitable for an interview or observation.
Students recently completed a progress check on photosynthesis and respiration. This lesson introduces homeostasis to the students, from the topic Bioenergetics.
LOs: (We are learning …)
• What homeostasis is.
• To apply key words; homeostasis, temperature, enzyme, hypothalamus, receptor, stimuli, effector, coordination centre
Differentiated for learners:
All students will be able to explain what is meant by homeostasis
Most students will be able to explain why it is important to control the internal environment
Some students will go even further and be able to describe the interactions of the key elements of control systems
As usual, I respect copyright so as a result I have not included some resources for this lesson.
A handout for students included would have been a mixture of relevant resources from Boardworks and Footprints. For copyright reasons I have not included this. Use other resources, such as textbooks or the internet to gain this research if these resources cannot be obtained.
Question table obtained from Q4 of this lesson on www.kerboodle.com with your school’s username and password, again you will need to sign up for this for copyright reasons.
