Updates to Videos and Workbooks
UPDATE 6 June 2021
This update applies to ebooks and printed books for Biology 2 Triple, Combined Science Higher and Combined Science Foundation. In the chapter Required Practical: Sampling, question 1c should read “The students counted snails. They used a 0.25m2 quadrat which they threw ten times. They found 84 snails.“
UPDATE 27 January 2021.
This update applies to the ebooks and printed books for Biology 2 Triple. In the chapter Pyramids of Biomass, question 1f should read “Explain why mammals and birds expend a greater amount of energy in respiration than other animals.” The answer should read “Mammals and birds maintain a constant body temperature even when the environment is cold. This means that they need a high rate of respiration to release the energy for this. In contrast, animals that do not maintain a constant body temperature do not need such a high rate of respiration.”
UPDATE 12 January 2021
This update applies to the ebooks and printed books for Biology 1 Triple, Combined Science Higher and Combined Science Foundation. In the chapter Bioenergetics Required Practical Photosynthesis question 3, the answer should read “In the table, we have 36 and 40. This gives us a total of 76. Dividing 76 by 2 gives us a mean value of 38.”
The answer PDFs have been updated. Please download the updated version.
UPDATE 23 August 2020
This update applies to the ebooks and printed books for Physics 1 Triple. In the chapter Nuclear Fission and Nuclear Fusion, question 3 should say “Krypton” for the second product of the reaction, rather than “Strontium”.
UPDATE 11 August 2020
This update applies to the ebooks and printed books for Physics 2 Triple, Combined Science Higher and Combined Science Foundation. The chapter “Acceleration” has an omission in the answer to question 4a (Triple and Combined Science Higher) and question 4 (Combined Science Foundation). The acceleration of the car during part C of the graph should have a negative sign as the car is decelerating. The correct answer is -0.096 m/s2 East.
UPDATE 5 August 2020
This update applies to the ebook and printed book for Physics 2 Triple. The chapter “Floating or Sinking” has a mistake in the diagram for question 3. The correct diagram is below.
UPDATE 21 May 2020
This update applies to both the ebook and printed book for Physics 1 Triple, Combined Science Higher and Combined Science Foundation. The chapter “Power of Components” has been updated. This affects question 3 only. Please download the updated question from the link below (the answer to this question has not changed).
UPDATE 20th April 2020
This update applies to both the ebook and printed book for Biology 1 Triple. The video for Monoclonal Antibodies has been updated. This has affected question 2. Please download the updated question 2 from the link below (the link also includes the updated answer).
UPDATE 29th February 2020
This update applies to both the ebook and the printed books Physics 2 Triple and Physics 2 Combined Science Higher. The answers to the chapter “Vector Diagrams” contains an error. For question 3a, the answer should say that the scale chose is 1cm = 0.5N and the resultant force is 6.6N. The answers to the Amazon books have been updated and the answers to the ebooks will be updated tomorrow.
UPDATE 8th February 2020
This update applies to both the ebook and the printed book Physics 2 Triple. The chapter “Magnifying Glasses” has a mistake on the diagram. The correct diagram is shown below. Both the ebook and the printed book have been updated with the correct diagram.
UPDATE 19th March 2019
For the Physics 2 video Required Practical 7 Acceleration, there is an omission in the first part of the practical (investigating how the force affects the acceleration of an object of constant mass). We are changing the force on an object, while keeping the mass constant. To do this, we use a mass on the end of a string to provide the force (which is the weight of the mass). We then change the force applied by decreasing the mass on the end of the string. Now the key point here is that we must not change the overall mass of the system. So, when we remove mass from the end of the string, we need to transfer that mass onto the toy car. That way, we have reduced the force applied (ie the mass in the end of the string) but we have not changed the overall mass of the system.
Sorry about that. I will update this video for 2019-2020.
UPDATE – 11th March 2019
We have made a change to the Chemistry Paper 1 Triple book. Chapter 4 – Structure and Bonding page 33 has been updated with the answers for the first section (The Three States of Matter). Please re-download that chapter from your accounts page.
Please revisit this section periodically to check for updates or changes to Videos and Workbooks.
I am now taking bookings for school visits.
You can get more information on the School Visits page.
Are your Videos and Workbooks for the AQA specifications?
Yes both the Videos and Workbooks apply to the AQA specifications. However there is also a huge amount of overlap with the other exam boards. I will be producing specific Videos and Workbooks for the other exam boards in the near future, please check the website for updates.
Do the Videos cover Higher and Foundation?
Yes, all of the Higher and Foundation content is covered in the videos. Anything that is specifically for Higher students is clearly flagged up in the relevant video.
How do I buy a Workbook?
Click on Workbooks, this will take you to the relevant section of the shop. There are workbooks available for Triple, Combined Science Higher and Combined Science Foundation. Be careful to select the correct workbook.
All payments are taken through Paypal although you do not need a Paypal account.
How do I view a Workbook?
When you buy the workbooks you will be emailed the files you need and instructions on how to view them. Keep your eye out for two emails (check spam folders), one from freesciencelessons (order complete and file download emails. If you used a Paypal account this one will go to that address) and one from Locklizard Licensing (instructions, viewer download and your license file. This one will go to the address associated with you freesciencelessons account).
The workbooks are protected PDF files that are licensed specifically to you and your device (2 maximum), after purchase you will need to download the secure viewer and upload your license to view the files.
If you have any issues using the viewer please visit the Locklizard Knowledge Base in the first instance.
Can I view the Workbooks on any device?
The Workbooks are secure PDFs viewed through the Locklizard Safeguard viewer, the viewer is available for MacOS and Windows computers and viewer apps are available for both iOS and Android mobile devices. The viewer will NOT work on jailbroken devices or ones with custom ROMs installed. The viewer will also not work on an Android emulated environment.
Can I print the workbooks?
Yes. Because the workbooks are very large I have divided them into smaller chapters to make it easier for you to print them. The license entitles you to print a total of two copies of each chapter.
Please note that printing of the workbooks is not possible from mobile devices.
Do I need to be connected to the Internet to view a Workbook?
You need to be connected to the internet to be able to purchase a Workbook, install the viewer and upload your license. After this has been done the viewer will connect to the Internet every seven days to check for updates and license changes etc.
How do I know if the workbooks have been changed or updated?
I do update the workbooks (and the videos) periodically, often because I want to make something clearer. You need to regularly check the updates section in the FAQ.
Will you be making Videos and Workbooks for other exam boards including iGCSE?
Yes, I am planning in the future to cover all the main exam boards including iGCSE. This will take some time though.
When will the other Workbooks be available?
Each Workbook covers every single video and takes a great deal of time to write. I am aiming to release a new Workbook every two to three months.
I think I spotted a mistake in a Video/Workbook what should I do?
Occasionally the odd mistake does crop up and I really appreciate it people let me know. If you do think you have spotted a mistake please leave a comment on my youtube channel freesciencelessons or via twitter (@ukscienceguy).
Can I get a level 9 if I just watch your videos?
Some students may be able to get level nines by basing all of their revision on my Videos (as well as past paper questions). However I would strongly recommend buying my revision Workbooks as these complement the Videos and will make your revision much more effective. I should point out though that the grade you get will depend both on your ability and the amount of work you put in. I cannot guarantee any grade for any student.
Where are the A-level Videos?
I have already produced several videos on A-level Biology and Chemistry and will be producing more later in 2019. However I am focusing on the GCSE Workbooks at the moment and these are involving a great deal of work.
Why are the Videos free but the Workbooks aren't?
It’s really important for me that the Videos are free. This means that anyone around the world can benefit from them. However the Workbooks take hundreds of hours to produce. I should point out though that I’ve made the Workbooks as cheap as I can. Considering the huge amount of content in them I think they are really excellent value for money.
Can you make a Video on a specific topic if I contact you?
Sorry but I cannot provide that service. Each Video takes around 5 hours to produce. I still have to make GCSE Videos for other exam boards and also A-Level Videos.
If you have any issues with viewing the Workbooks or other problems not covered in the FAQ then please email firstname.lastname@example.org.
