Grade 5 Science games, Term 1: The Time-Lapse Watch

The magic watch speeds up time: children watch a seed sprout, a flower become a fruit, the seasons change and water travel round its cycle — and do it all with their own hands: contract a muscle to lift weights, guard the brain and heart with bones, spot a fair test from a cheat, and deliver pollen with the bee. All 9 chapters of the Grade 5 Science book (Term 1, Egyptian curriculum), lesson by lesson, in English or Arabic — every step in simple words, then a question from the book, and stars at the end.

Every lesson is a mission: stops open in order; at each one Azzouz explains the idea simply, the child plays it with their own hands (points, combos and a record to beat), wins a key 🔑 and answers a book question. In the middle “Run from the monster!” to collect stars, and at the end the big challenge with the lesson questions and stars ⭐. A wrong answer shows the book sentence with the answer. “📝 Exam practice” has the book’s question types, and in “🤝 Who’s the best scientist?” they pick chapters and play a quiz, chess or bowling with Azzouz or friends.

Parents’ questions 💬

Is it free?

Yes, completely free, no sign-up, and no ads inside the game.

Are the questions from the Ministry book?

Yes. Every question and every fact comes from the Grade 5 Science book, Term 1, and the Ministry assessment book, with the book pages next to every lesson.

English or Arabic book?

Both. Children pick the book they study at school — 📘 English (Languages schools) or 📕 Arabic — and can switch any time. Every English line has a small Arabic line under it for parents.

What is a “mission”?

Every lesson is a story with Anwar and Azzouz in “The Time-Lapse Watch”: stops that open in order, each with a simple explanation and a hands-on game (contract a muscle to lift weights, guard the brain and heart, plant beans in cups, deliver pollen with the bee), then a book question. In the middle a run from the monster to collect stars, and at the end the big challenge with the lesson questions.

Do they learn a fact before they are asked it?

Yes. Every fact is told in the story before any game or question needs it, so children don’t need to have read the book first.

What is “Who’s the best scientist?”

Pick the chapters, then play a quick-fire quiz against Azzouz or a friend (same phone or online with a code), or science chess or bowling. Winners can share a picture of their win.

Can parents follow progress?

Yes, the “👨‍👩‍👧 Parents & teachers” page shows stars, lessons to revise, the questions answered wrong with the book sentence, and a report to send on WhatsApp. Every question has “🚩 Something wrong in this question?”.

Does it work on phones?

Yes, on any phone, tablet or computer. Add it to the home screen like an app and it works offline (except online play).
