Interactive Tools
Zoom into cells, unwind DNA, build force diagrams, and explore passive cooling.
A small library of interactive web tools for science teachers and students. Built to project in lessons, work in revision, and stay out of the way. No accounts. No ads. Just open and click.
Biology
07 toolsZoom into the Cell
cell → nucleus → DNA
A continuous zoom from a whole cell down to the bases of DNA. Toggle between animal, plant, and bacterial cells. Click any organelle for GCSE-level detail.
Zoom into DNA
a double helix, in five steps
Chromosome → double helix → gene → nucleotide → base pairs. Built for Triple Biology. Click each part of a nucleotide to see what it does and why it matters in the exam.
Genetics Vocab
twelve questions · staged reveals
A check for understanding for the seven core genetics terms: allele, dominant, recessive, genotype, phenotype, heterozygous, homozygous. Twelve questions move from forward chains through reverse problems to a final trick question — each answer reveals in stages so a teacher can cold-call between every step.
Genetics Recap
whole-unit recap · diagnose, recall, practise
A teacher-led recap of the whole B9 inheritance unit, built for the first lesson back. Opens with diagnostic hinge questions, then moves through five sections — DNA structure, alleles and genotype/phenotype, Punnett squares, sex determination, and genetic disorders — each with a recall prompt, a quick task, and independent practice. Tackles the “1 in 4” misconception head-on and ends with a say-it-then-write-it task.
Specialised Cells
six cell types, six adaptations
Sperm, egg, ciliated, root hair, nerve, red blood. Click adaptation hotspots to learn how structure links to function — with mark-scheme-aware exam tips.
The Microscope
eyepiece, objective, focus
An interactive microscope for the classroom — adjust magnification, focus the image, and explore what a real specimen looks like under the eyepiece. Pairs well with the cell-zoom tool above.
Diffusion & SA:V
why small cells diffuse faster
Particles diffuse from a high concentration outside a cell to a low concentration inside, until equilibrium. Three sliders change the rate — temperature, concentration gradient, and the cell's surface area : volume ratio — with a live crossings counter and a time-to-equilibrium readout. Built to make the counterintuitive result visible: a bigger cell has more membrane but fills more slowly.
Physics
05 toolsForce Diagram Builder
drag, label, balance
Build free-body diagrams for objects in motion or equilibrium. Drag force arrows, label them, and see whether the resultant is zero.
Particle Model
why solids, liquids, and gases behave that way
Watch particles in solids, liquids, and gases. Heat them, cool them, change their state. Explore how the model explains pressure and diffusion — the everyday physics behind the everyday world.
Energy Stores
a roller coaster, three stores, conservation
Drag a cart along a roller-coaster track and watch gravitational and kinetic stores swap energy. Toggle friction to see thermal appear. Predict-mode hides the answer until you're ready. Total energy stays at 1000 J — conservation, made visible.
Specific Heat Capacity
build the apparatus · sequence · 6-marker
A five-stage builder for the AQA Combined SHC required practical. Click through the apparatus stage-by-stage, sequence the method on an empty bench, drill equipment and method with quizzes, fix a bad 6-marker, then write your own with a scaffolded frame. Built for Year 9 first attempts at the extended response.
What is Power?
two fans, two batteries — power as a rate
A teacher-talk diagram for introducing power. Two fans run side by side on Low and High while their batteries drain live — High empties faster. Build the idea one step at a time: same stores, same transfers, just more energy each second. Each step has a cold-call prompt with a teacher-controlled answer reveal. Click or use arrow keys to advance.
Chemistry
03 toolsAtom Counter
read a formula · count the atoms
Drop a chemical formula in — H₂O, CO₂, Ca(OH)₂, 2H₂SO₄ — and see exactly how each atom is counted, including subscripts, brackets, and big multipliers. Built for KS3 to make formula-reading click.
Naming Compounds
three rules · then the test
The three KS3 naming rules — –ide for metal + non-metal (NaCl), prefixes for two non-metals (CO₂), and –ate names for polyatomic groups (CaCO₃). Each rule starts with a prediction, walks through an animated worked example, then four tap-to-build practice questions. Ends with a mixed challenge where pupils have to choose the rule themselves — including the AlCl₃ trap.
The Rock Cycle
three rock types · one endless loop
An interactive hub: tour the Earth's layers, then click each process — cooling, weathering & erosion, heat & pressure, melting — to see how igneous, sedimentary and metamorphic rocks turn into one another. Opens into full explorers for each rock type, including a crystal-growth lab and a fossil-forming sequence.
Environmental Design
01 toolRevision Booklets
Bitesize topics, with answers you can hide and reveal.
Topic-shaped revision booklets, sized for one sitting. Hide-and-reveal answers, embedded interactives, and bitesize summaries — built to work on a phone the night before, or in school during tutor time. No login. No tracking.
Year 7
05 resourcesCells, bitesize
eight short topics · microscopes to specialised cells
Why we need microscopes, the parts of one and how to use them, what's inside every cell, animal vs plant cells, the magnification equation, unicellular bacteria, diffusion in and out of cells, and four specialised cells. Each topic is a bitesize summary with hinge questions and a hide-and-reveal quiz. Print-ready PDF pack included.
Particles, bitesize
four short topics · solids, liquids, gases, pressure
The particle model and how to draw it, properties of states and why they flow, the four changes of state with melting and boiling points, and gas pressure as collisions. Includes the particle simulator embedded at three different points — states, heating, and pressure.
Atoms, bitesize
six short topics · atoms to the periodic table
What an atom is and how it differs from an element, how our model has changed from Dalton's solid sphere to Bohr's planetary model, the three subatomic particles (PEN), reading atomic number and mass number, electron configuration in shells (2, 8, 8), then using group and period numbers to predict electron arrangements. Ten worked examples with a labelled Bohr atom and a simplified periodic table.
Energy, bitesize
six short topics · stores, transfers, joules
Fuels and the chemical store, joules and kJ, heating, kinetic and gravitational stores, the elastic store and transfer by a force, then transfers by electric current and waves. Includes the energy-stores roller coaster interactive embedded at the right moment.
Power, bitesize
six short topics · the equation, units, calculations
What power means and how to compare devices, the power equation P = E ÷ t, calculating energy with E = P × t using the FIFA method, kilowatts and kilojoules, working with minutes in calculations, then linking back to energy stores and conservation. Twelve worked examples and a watch-out for every common unit-conversion mistake.
Year 8
02 resourcesGenetics, bitesize
five short topics · hide-reveal answers
