Frequently asked questions
Which science exhibition project is best for Class 5?
Popular Class 5 science exhibition projects in the ebook include the Obstacle-Avoiding Robot Car, Line-Following Robot, IoT Wi-Fi Weather Station and AI Gesture-Controlled Robot Arm. Each comes with viva questions and a presentation script.
What are easy school projects for Class 1 and Class 2?
For Class 1, try Rainbow Walking Water, Balloon Rocket Race or Paper Cup Telephone, made with things from home. For Class 2, the Lemon Battery, Pizza-Box Solar Oven and Light-Up Greeting Card are easy working models.
What do I get, and in what format?
One PDF ebook of 400 A4 pages: 50 step-by-step STEM projects for Std. 1 to 5 in five levels, a technology guide, a component picture dictionary, 10 bonus ideas, a progress tracker, a completion certificate, an evaluation sheet and a glossary.
How will I receive the ebook?
It is an instant download. As soon as your payment is confirmed you get the download link on screen. Nothing is posted to you.
Can I open it on my phone, and can I print it?
Yes. The PDF opens on any phone, tablet or laptop. It is sized for A4 paper, so you can print the whole book or only the project you need, at home or at a print shop.
Which standard is it for?
Std. 1 to 5 (about age 6 to 11). Level 1 is for Std. 1 and each level climbs one standard, up to Level 5 for Std. 5. Older children who are new to STEM can start one or two levels lower.
How much do the materials cost?
Level 1 uses things from home. Every project lists its materials with an approximate rupee cost, so you can plan before you buy. For example, the electronics kit for Level 2 is about ₹250–400, while an Arduino robot car in Level 5 is about ₹1,400–1,800. Prices are approximate and vary by shop and city.
Do we need a computer?
Not for Levels 1 and 2. Level 3 uses Scratch, which is free and runs in a web browser. Levels 4 and 5 need a laptop or desktop computer with a USB port to upload code to the Arduino board.
Which levels need an Arduino?
Levels 1 to 3 need no Arduino. Arduino (or a compatible board) is used in Level 4 and in most Level 5 projects, and the IoT projects use a Wi-Fi board. The ebook explains what to buy, level by level.
Are the projects safe for children?
All electronics projects use low-voltage batteries or USB power only, never 230V mains. Steps that need a grown-up are clearly marked ADULT SUPERVISION REQUIRED or CHILD SHOULD NOT PERFORM THIS STEP ALONE.
