Rebuilt 48 labs across computer science, mathematics, physics and biology as the fifth lab generation. Each now opens with short warm-ups that build the scene up piece by piece, asks you to act on the object itself, dragging, cutting, wiring, swinging or sliding it, instead of choosing from menus, keeps your working and your record beside the picture, and shows the result of every test in the same view on a phone or a laptop. An Experiment mode on the same model is open from the start, so you can explore freely and come back to the guided path where you left it.
Added eight new labs: Search and Sort, Digital Signatures, File Access and Hashing and ASCII and Unicode Character Encoding in computer science; Powers, Roots and Index Structure in mathematics; and Exercise and Breathing, Oxygen Debt and Recovery and Transport in Plants in biology, which open the Gas exchange, Respiration and Transport in plants topics.
Added Business as a new subject for Cambridge IGCSE Business 0264, with its own catalogue page and two guided labs: Quality Control and Assurance, where you place an inspector in a stool workshop and stop faults at their cause, and Exchange Rates and Trade, where you move the rate at a currency booth and pay real import bills and export orders to see who gains when a currency strengthens.
In computer science the networking, hardware, logic and data labs are now guided: you cut a message into packets and route it, choose when each Ethernet station sends, step a real program through the CPU, wire gates and flip-flops and test every input, follow pages from the drive into RAM, and sign, encrypt, hash and search real data to see what each mechanism catches.
In mathematics every geometry, number, algebra, probability and statistics lab is now a construction you make and test yourself: swing a rod to find how many triangles fit, tilt a line and read its equation, stretch a solid to a target capacity, place pupils in Venn regions, spin a fair and a biased wheel, slide decimal rows until the repeating tails cancel, and build the triangle or shape that checks your answer.
In physics and biology you turn a laser to find the critical angle, push a piston and use your own readings to find pV, slide a lens and screen to focus real images, change coil turns and watch grid losses, drag a ripple-tank gap, change the seeds a bird population can reach, read a breathing trace, follow lactic acid to the liver and cut a watered plant to find xylem and phloem.
Lab pages for the new generation fill the frame exactly as reviewed, with the exam alignment shown as syllabus chips beside the site name on wider screens; catalogue cards for the new and redrawn labs (including Solids, Time Zones, Memory Management and Data Transmission) follow the new card style with one blue accent.
Redrew every catalogue card illustration in a consistent, simpler style, with one small blue accent marking each lab’s key idea.
Redesigned the developer guide and design system pages as one consistent reference, covering how labs teach, how they are built and checked, and every shared colour, type style and component.
Rebuilt two networking labs as guided step-by-step investigations that work on phones as well as laptops. In TCP/IP Protocol Stack you choose the wrapping order, the layer that reads each header and the ports and addresses, then send the bundle through a router and see exactly where delivery holds or stops. In Encryption in Data Transmission you predict what the receiver and an eavesdropper will see, fit symmetric or asymmetric keys, then send and watch who can read the message.
Added a “Try our Exam Builder” link to the About page from the homepage and subject catalogue headers, with an animated monochrome mark and styling that matches the footer links.
Reworked four Mathematics labs around clearer guided investigations of coordinate geometry, non-right triangles, prime factors, and ratio with flow rate.
Added a guided transformer and power-transmission investigation that connects winding ratios, cable current and heating loss.
Reworked Circle Theorems around guided geometric investigations, with consistent missions and working, progressively introduced calculations and theorem reasons, and an open experiment for comparing constructions.
Reworked Motion Graphs into seven connected trolley and graph investigations, followed by an open journey editor for comparing saved speed–time and distance–time profiles.
Catalogue cards now identify Guided and Simulation learning experiences where classified.
Guided labs keep their main interaction steadier, with more compact mission and feedback areas and checkpoint changes that preserve reading position.
Reimagined six investigations around direct visual manipulation, small guided steps, linked working and open experiments: similarity, straight-line equations, histograms, total internal reflection, gas compression and natural selection.
Restored full challenge instructions and accessible Run and Check controls in Python Programming Practice, with scrolling that keeps the workspace reachable above the site footer.
Organized the Pseudocode and Python Translator controls into settings and execution rows, stabilized button sizing, and clarified its icons across desktop and mobile layouts.
Fixed missed clicks when building TCP/IP packets, improved recovery when correcting a stack, and replaced repeated guidance prompts with one expandable explainer and one-time interaction introductions for the layers, Send and Compare controls.
Redesigned the homepage with four compact feature cards, explanatory tooltips and seven animated previews of real labs. Smooth aerial passes follow the action, with softer edges, a shared pause control and more breathing room above the catalogue.
Subject pages now lead with the subject name and place their selectors beside the first labs. Added the copyright symbol alongside the Examplicity trademark in site and download footers.
Refreshed all 57 labs with consistent Working and exam controls, clearer goals and evidence cards, readable labels and purposeful interaction cues, while preserving their distinct diagrams and workbench layouts.
Improved direct manipulation and working across Mathematics, including percentage bars, histogram handles, coordinate constructions and repeating decimals. Restored the Bounds instruments and proof stages, with separate Core and Extended investigations.
Clarified networking devices, packet flows and draggable parts; improved programming consoles, recursive frames and neuron controls. Memory Management now shows other ready CPU work continuing during page transfers. Parity & ARQ brings its byte matrices forward and shows result feedback when needed.
Made science predictions, measurement cards and checkpoints clearer, with direct controls and pulsing cues for required actions. Refined Selection’s population visuals and Gas Compression’s piston grip.
Added a developer and AI remix reference with a living design guide, learning contracts and practical adaptation guidance. Standalone downloads link to the live lab and developer reference.
Reduced offline download sizes across the catalogue while preserving self-contained operation and reusable design components for remixing.
Added flip-flop feedback, recursive call-stack and artificial-neuron investigations for Cambridge International A Level Computer Science 9618.
Added Cambridge IGCSE Mathematics 0580 investigations for similarity, relative frequency, expected frequency, replacement and conditional sample spaces.

Improved prime-factor progression and expanded replacement and similarity practice while preserving each lab’s direct manipulation and evidence trail.
Relicensed Examplicity under the MIT License.
Made direct and search-result lab links open inside the full Examplicity navigation and footer frame.
Improved standalone lab downloads, changing-state announcements, catalogue routing safeguards, and keyboard access to bitmap painting, scheduler arrivals, and sound navigation.
Standardized lab title headers across narrow and wide activities, expanded the pseudocode translator workspace, and kept assisted repeated-percentage challenges interactive.
Added keyboard control to circle constructions, network builders, transmission routing, and the 3D perspective check.
Kept the recurring-decimals manipulative fully visible without an internal scrollbar.
Added five Cambridge IGCSE Mathematics 0580 labs covering time-zone scheduling, sequence patterns, motion graphs, straight-line equations, and perpendicular-bisector construction.
Added five Cambridge IGCSE Mathematics 0580 labs for circle theorems, surface area and volume, right-triangle trigonometry, trigonometric graphs, and non-right triangle solutions.
Added five Cambridge IGCSE Mathematics 0580 labs for three-dimensional trigonometry, transformations, vectors, scatter diagrams, histograms and cumulative frequency.
