Some pointers and ideas to help you devise a method and practical for the new unit 19 applied science unit.
This practical is one of the 4 options for assignment B. I know that the use of IR for quantitative analysis is uncommon, but it can be done.
Find attached a journal article of a similar experiment and a short outline of a method (word doc). Journal is obviously not my own work, I have just uploaded these to help centres devise their own methods for this assignment.
I hope this is helpful for you.
Please take a look at my other resources :-)
A viscosity worksheet on identifying Newtonian and non-Newtonian fluids and a crossword which can be used as an end of topic/end of lesson activity. Both with answers!
Created for Level 3.
Laboratory design activity that could be used for an after school STEM club, mini science project, summer project or even a class task. Aimed at school level but can be as simple or challenging as you would like to make it :)
A supporting PowerPoint is attached with ideas for student instructions ie group tasks visiting laboratories, what to focus on/take notes + photos of. This can be quite hands on and you can let students measure things and do conversions, creating keys and grids in their own laboratory design plans, if you have the facility to do so.
Student (and teacher!) friendly assignment checklists for the first 2 assignments of Unit 18 (Industrial Chemical Reactions) in the Level 3 Applied Science.
I have created these using my own interpretations of the brief and teacher guidance.
Useful for teacher as can help speed up the marking process.
A resource created to assist teachers and students with delivery of the A2 OCR Chemistry PAGs.
A PowerPoint to help you structure the beginning of the PAG lesson on 10.2 thiosulfate and acid. Can easily be amended and used as a template if preferred. Alternatively, this could be given to students as a guideline to assist them with their planning and calculations.
Example results and graph for thiosulfate (part 1) included, showing the first order relationship.
Possible extension opportunities include monitoring how temperature affects the rate of reaction - an Arrhenius plot could then be done as part of the analysis. Recommended for A-A* students.
Gives students a checklist of what needs to be submitted.
PowerPoint for PAG 9.3 rates attached also. This one includes OCR past paper questions (and answers) at the end as a plenary.
A powerpoint presentation (consisting of activities and answers and a link to the RSC video on NMR) and worksheet (comic strip to help students condense information and remember the main points of NMR) to assist teaching with the new L3 Applied Science Unit 19.
This was created to help teach NMR spectroscopy. It has activities throughout and is step-by-step, I have simplified where possible.
Has a couple of extension/early finishers activities in.
I have created a series of 3 videos in which I teach NMR, the first can be found here and is about chemical equivalency :) https://www.youtube.com/watch?v=-fWA108hr8M
I created this lesson for the new unit 19 level 3 applied science, assignment B, spectroscopy. This lesson lasts about 1.5 hours including completion of activities and introduces the students to spectroscopy by recapping the electromagnetic spectrum (I have also included some points in the notes section of the powerpoint which you may wish to discuss).
The data sheet I used with my students was the OCR A A Level Chemistry one (just what was handy in the lab) and the PowerPoint refers to worksheet A which is part of their assignment. This can be found on the Pearson website, along with answers.
I have included a link to a video I created introducing IR spectroscopy, aimed at students :) https://www.youtube.com/watch?v=XxYTIuKYbvc
