Model of digestion
มุมมอง 4483 ปีที่แล้ว
A primary school model of digestion using buckets and tights to highlight the different organs along the alimentary canal and linking it to GCSE level content on chemical and physical digestion.
Introduction to Enzymes
มุมมอง 1233 ปีที่แล้ว
A video touching on the basics of enzymes, their structure and function, the lock and key theory, and a brief overview of the factors that affect their rate of activity. Aimed at those in the 4th form (Year 9).
Investigating the effect of temperature on enzymes
มุมมอง 4083 ปีที่แล้ว
Using celery as our source of catalase and some hydrogen peroxide, we see the volume of oxygen gas produced in 1 minute under different temperatures.
AQA GCSE Biology - Required Practical - Enzymes and pH
มุมมอง 7583 ปีที่แล้ว
Required practical for AQA GCSE Biology. Investigating the effect of pH on rate of enzyme activity. Enzyme = pepsin, substrate = albumin, present in a range of pHs.
AQA GCSE - Required Practical - Food Tests
มุมมอง 1873 ปีที่แล้ว
Required practical for AQA GCSE Biology. Using food tests to determine whether a solution/substance contains: glucose, starch, protein or lipid using the Benedict's, Iodine, Biuret and Emulsion tests.
Cauliflower Cloning
มุมมอง 7673 ปีที่แล้ว
Micropropagation is the regeneration of whole plants from small pieces of plant material. In this case we use a tiny piece of a cauliflower, an explant, in place of the endangered species that the protocol was designed for. This was done using SAPS' protocol.

Ultrafiltration and selective reabsorption
Dude THANK YOU this helped me with the teretetary (even I don’t even know how to say it) Strutcture
Hey great videos ! I just wanted to ask, the experiment where you measured yeast respiration, you had used oil, could you please tell me what oil it was, that would be great !
Hi there and thanks! It was just some sunflower/cooking oil.
FUN FACTS: -Shadows are darker on the moon -Sloths can hold their breath longer than dolphins can -People used to say "prunes" rather than "cheese" when having their photo taken - The largest recorded snowflake was in Keogh, MT during year 1887, and was 15 inches wide -The average person walks the equivalent of three times around the world in a lifetime -You cannot snore and dream at the same time -A sneeze travels about 100 miles per hour (faster than a cheetah) -I met Harry Styles in 2014 (to this day, its the best thing that's ever happened to me) p.s what's your view on Liam's split with Cheryl

These are the type of videos I live for. Some people love football, some people love alcohol but me, I'm all about that nerveimpulsestopmotion #Biology4life #inspirational
Thanks bois, really helped out with my revision
Life changing
Thanks guys!!! Stumbled during my biology revision!! Really useful!!!! Keep up the good work 😊
Now I can pass my GCSE Biology. Thanks Cecelia. More like traitor lol. Gayyy.
