Archimedes Bucket and Cylinder

I measure the weight of a mass using a spring balance, then submerge it in water. The buoyant force reduces the weight, but adding the same mass of water to the bucket restores it. A simple and clever demonstration of how the displaced water equals the mass added!

 

Peptide Bond

​Exploring protein structure in A-Level Biology: Starting with simple amino acids like glycine and alanine, forming a peptide bond by removing water. Step by step, building the protein's primary structure. #Biology #ProteinSynthesis #STEM

Sugar added to food

 Exploring sweet taste preferences in A-Level Psychology: Evolutionary pressures associate sweetness with high energy and non-toxicity. Food companies exploit this by adding excessive sugar to products, appealing to our natural instincts. #Psychology #FoodScience

Building a Network

 A-Level Computing: Understanding networking theory is one thing, but building a network from scratch is a whole new challenge! Students configured devices to communicate, added resilience with a load balancer, and set up a firewall for security. #Networking #ComputingEducation

Optically active Glucose

 A-Level Chemistry: Viewing a glucose solution through two polarising filters. The light is initially extinguished, but glucose rotates it, allowing some to pass through. This is dextrose; laevose rotates the light in the opposite direction. #Chemistry #OpticalActivity

Galileo's Bells

 Using Galileo's Bells to demonstrate the square relationship of acceleration: With the @pascoscientific smartcart for precise data recording and a very inaccurate water clock for interval timing. A perfect blend of modern tech and historical methods! #Physics #STEM

Sum and Products of the roots of Polynomials

 Exploring the sum and product of polynomial roots: Teaching students how coefficients reveal the relationships between roots and equations. A key concept bridging algebra and deeper mathematical insight! #MathsEducation #Polynomials
