Easy science experiments at home with things from your kitchen — floating and sinking, a honey-oil-water density tower, a rainbow in a glass, a balloon rocket, baking soda and vinegar, turmeric that changes colour, sprouting seeds, magnets, a pendulum, a paper bridge and a periscope — 27 safe experiments and STEM projects with a full explanation of why they work. Each lesson lists what you need, numbered steps, what happens and why, a fair-test check, safety tips, “Show me how” help, a 20-question test, a badge, printable worksheets and free certificates.
🧪 Quick check: Floating and sinking
Each lesson has the idea, a worked example, unlimited practice with “Show me how”, a 20-question test and worksheets. Pass a lesson’s test to earn its badge; pass every lesson in a part to earn that part’s certificate (sign in to keep badges, certificates and progress).
Ages 6–14 (younger children with an adult reading along) — floating and sinking, a honey-oil-water density tower, dissolving sugar in warm and cold water, a colour-changing flower, a rainbow in a glass, the card-on-a-glass air pressure trick, a balloon rocket, a paper helicopter, the water cycle in a bowl and a Part 1 test.
Ages 7–14 — baking soda and vinegar, turmeric as an acid–base indicator, lemon invisible ink, sprouting seeds, how plants give out water, the yeast balloon, butter from cream, growing salt crystals, filtering muddy water and a Part 2 test.
Ages 8–14 — static electricity with a comb, magnetic and non-magnetic things, pendulum timing, a ruler-and-coins lever, a thread-reel pulley, the paper bridge challenge, shadows and a sundial, a mirror periscope, the scientific method and the final test.
They are classic, safe science experiments and STEM projects you can do at home with an adult, using everyday Indian household items: water, salt, sugar, honey, oil, baking soda, vinegar, lemon, turmeric, cotton, seeds, paper, coins, string, a comb, a magnet and two small mirrors. The course has three parts: Water and air (floating and sinking, density tower, dissolving, capillary action, a water rainbow, air pressure, balloon rocket, paper helicopter, the water cycle in a bowl), Kitchen chemistry and life (baking soda and vinegar, the turmeric indicator, lemon invisible ink, sprouting seeds, how plants give out water, the yeast balloon, butter from cream, salt crystals, separating mixtures) and Physics and STEM projects (static electricity, magnets, the pendulum, a ruler lever, a thread-reel pulley, a paper bridge, shadows and a sundial, a periscope and the scientific method). Every lesson explains WHY it happens and teaches the fair test: change one thing, keep the rest the same, measure the result. Lessons 10, 20 and 30 are mixed tests.

Floating and sinking in a tub, a honey-water-oil density tower, sugar dissolving in warm and cold water, a white flower changing colour, a rainbow from a glass of water, the card-on-a-glass air pressure trick, a balloon rocket, baking soda and vinegar, turmeric that turns red in soap water, sprouting moong seeds and a magnet hunt. Each lesson here lists what you need, numbered steps and the explanation.
Yes — when an adult helps. Every experiment uses everyday kitchen and stationery items. Safety rules: an adult is always present; nothing from an experiment goes in your mouth; no flames; children use only safety scissors and an adult does any cutting; any heat (a warm iron) and any hot water are handled only by the adult; never look at the Sun; never play with plug points; wipe up spills at once; keep small items like magnets, coins and balloon bits away from little children; and wash your hands afterwards.
हर हफ़्ते एक प्रयोग चुनें और बच्चे के साथ पहले “क्या चाहिए” और स्टेप पढ़ें। पहले बच्चे से अनुमान लगवाएँ कि क्या होगा, फिर प्रयोग करें और जो दिखे उसे लिखवाएँ। आख़िर में “क्यों हुआ” समझाएँ और 10 सवाल हल करवाएँ। हर बार कोई बड़ा साथ रहे, कोई चीज़ मुँह में न डालें और प्रयोग के बाद हाथ धोएँ।
Ages 6 to 14. Children of 6–8 enjoy the experiments with an adult reading the steps aloud; 9–11 year olds can do most steps themselves and answer the why questions; 12–14 year olds can plan fair tests, use the pendulum and lever sums and write lab reports.
Yes. Every lesson says what happens and WHY — density, dissolving, capillary action, refraction, air pressure, acids and bases, germination, transpiration, static electricity, magnetism, levers, pulleys, reflection and more — in short, child-friendly sentences, with “Show me how” steps for every question.
A fair test changes only ONE thing (the variable we change), keeps everything else the same, and measures the result. For example, to see if sugar dissolves faster in warm water, change only the water temperature and keep the amount of water, the amount of sugar and the stirring the same, then time it.
Yes. Every lesson has free printable worksheets with an answer key — print them, save them as PDF or solve them online. Each time you open a worksheet you get a fresh set of questions.
Sign in and pass the 20-question test of a lesson (16 or more right) to earn its badge. Pass all ten lessons of a part — Part 1 is lessons 1–10, Part 2 is 11–20, Part 3 is 21–30 — to get that part’s certificate, with a code anyone can check.
Yes. All 30 lessons, practice, tests, worksheets, badges and certificates are free. Classes with a TalentJR teacher (online or at home) are paid — request a call back for fees.
