The 19 sets
Play this set opens the set in splycr, where you can read every question and host it for your class straight away. Hosting needs no account, and students join with the code on the board. A free account lets you copy a set and edit it.
The questions were written for the splycr library by Biology by Bradford. Each one plays as multiple choice, and the three wrong options were written for that question.

What the sets cover
Nineteen sets on the biology most courses teach around Grade 10, one topic each: cell structure, microscopy, transport in cells and cell division; biological molecules in four sets (metabolism, carbohydrates, lipids, and proteins and nucleic acids) and an overview set to finish them; enzymes, photosynthesis and respiration; DNA and protein synthesis, inheritance, evolution and natural selection, and classification; ecosystems and energy flow, and nutrient cycles and human impact; and the human body systems. Play the set for the topic you have just taught, or use them together as a review of the basics before IB or AP Biology.
Where students slip
- Osmosis is the movement of water, not of the dissolved substance, across a partially permeable membrane, from a dilute solution to a more concentrated one.
- An enzyme that is too hot is denatured, not killed: the shape of its active site changes, so the substrate no longer fits. Enzymes were never alive.
- Plants respire all the time, day and night. In the light, photosynthesis is faster than respiration, so the plant takes in more carbon dioxide than it gives out.
- Condensation joins two molecules and releases water; hydrolysis uses water to break the bond. Both are catalysed by enzymes.
Game modes that suit these sets
Every set plays in all eight modes. These two fit these sets best.
Racer solo
In solo Racer the track is as long as the set, up to 12 cards, and one wrong answer sends a student back to the start. Every General Biology set has 16 to 20 questions, so finishing takes twelve right answers in a row.
Boss Battle
Biology is full of pairs that look alike under pressure: diffusion and osmosis, aerobic and anaerobic respiration, condensation and hydrolysis. A wrong answer heals the boss, so a class that guesses loses ground.
Why review with a game
Answering from memory does more for recall than rereading notes, and a game gets the whole class answering, not just the students with a hand up. Every question in these sets is short, with a one-line answer, so a set makes a quick starter, a check at the end of a topic, or a review before a test.
How a class plays
- Open a set and press Host a game. Pick one of the sets above and choose a game mode. You don't need an account to host.
- Put the room code on the projector. It comes with a QR code that opens the game on a phone.
- Students join with the code and their first name. They go to splycr.com on a phone, tablet or laptop. No student accounts, nothing to install.
A free account lets you copy a set to edit it, write your own, and set it as homework.
Eight ways to play the same set
- Boss BattleThe whole class fights one boss. Right answers hit it, wrong ones heal it.
- RacerEach right answer moves you forward. Play solo or in teams.
KaboomAnswer right to pass the bomb on. Hold it when it goes off and your points go to everyone else.
SabotageRight answers earn coins and cards that freeze, steal, swap or shield.
ThroneOne student holds the throne and the rest of the class tries to take it.
SplycrQuick-fire questions. A streak stacks your multiplier up to three times.
CryoA frozen arena of frost charges. Answer a question to reload.
OutbreakA first-person zombie arena for laptops. Answer right to get back in.
Questions teachers ask
Do students need an account?
No. Students join with the code on the board and their first name, from any browser. There is nothing to install.
Is it free?
Hosting a game is free, with or without an account, and so is an account. Only generating new questions with the question generator uses credits; these sets are already written.
Which course do the sets follow?
No single exam board's. They cover the biology most courses teach around Grade 10, from cells to ecology and the human body, so they suit GCSE, IGCSE and MYP classes, or a review of the basics at the start of IB or AP Biology. Each set is one topic, named plainly.
What kind of questions are they?
Short questions with a one-line answer: a word, a name or a structure, such as the organelle where most aerobic respiration takes place, or the bond that joins two monosaccharides. They are for retrieval practice and vocabulary review.
Where do the questions come from?
They were written for the splycr library by Biology by Bradford. The biological molecules sets follow its own question sheets, retrieval quiz and task cards. Each question plays as multiple choice, with three wrong options written for that question.
Can I change the questions?
Yes. A free account lets you copy any set and edit it, or write a set of your own.
Teaching older classes, or chemistry too? The library has sets for these courses as well.
