⚡ Veda Bites

The whole idea, one bite at a time

Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.

💡 Key Idea

Science is a process

A way of working, not a stack of facts.

Notice something. Shape it into a question. Think of a possible answer. Test it. Then read the result honestly, even when it disagrees with you. That sequence is science. The facts in your book are what it has produced.

💡 Key Idea

From what to how and why

The questions change this year.

Grade 6 asked mostly what things are. Grade 7 asks how they work and why they behave as they do. The second kind of question is harder. It is also the kind that explains the world instead of listing it.

💡 Tip

Aim one of three at any page

Three questions, all year.

When a chapter looks like a pile of new words, pick one and point it at the page.

💡 Key Idea

Curiosity comes first

Nothing lifts off without it.

Before looking and before testing comes wanting to know. Every piece of science began with somebody feeling that. Instruments without curiosity find nothing. Curiosity with only a pair of eyes can still start today.

💡 Key Idea

Nobody hands you the question

Half the skill is choosing the question.

In class you get a question and hunt the answer. A scientist must also decide which question is worth asking at all. Nobody hands them that, and the wrong choice wastes months of work.

✏️ Example

Just make it half

One answer, three questions.

Suppose the answer is to make it half. Somebody might have asked how to share a cake fairly. Or how to shorten an essay. Or how to fit a thing into an envelope. The answer alone does not tell you.

1

Science as an Ever-Evolving Process

Science is a way of working, not a stock of facts. Grade 7 moves from asking what a thing is to asking how it works and why. Its explanations get rebuilt whenever careful evidence disagrees with them.

  • Science is a way of working: notice, question, guess, test, then read the result honestly.
  • Grade 6 largely asked what things are; Grade 7 asks how they work and why they behave so.
  • Three questions guide the year: how does it work, why does it happen, what does the pattern mean.

Exploring, Asking and Taking Responsibility

Curiosity starts science, and asking the right question is half the skill. Activities are the stepping stones, not breaks. What people do changes nature and society, so science carries a duty as well as an explanation.

  • Curiosity comes before observing and testing, and every piece of science began with it.
  • In class you are given questions; scientists must also decide which question is worth asking.
  • One answer can fit many different questions, so the question fixes what the answer means.

70 questions laddered from warm-up to topper-level, each with an explanation. A taste:

Which statement describes science most accurately?

Beginner
A A way of working that notices, questions, tests and reads results B A fixed collection of facts that students are required to memorise C A set of experiments that can only be performed in a laboratory D A list of answers that stay the same once somebody has printed them
Show answer & explanation

A way of working that notices, questions, tests and reads results

Science is a way of working. Facts and experiments occur inside it, but neither is what it is.

Compared with Grade 6, the questions in Grade 7 science shift towards asking

Beginner
A what the different things around us happen to be called B which chapters of the textbook will appear in the examination C how a thing works and why it behaves the way it does D where in the world each scientific discovery was first made
Show answer & explanation

how a thing works and why it behaves the way it does

Grade 6 largely asked what things are. Grade 7 moves to how and why, which are the questions that explain.

Kavya rubs soap on a yellow haldi stain and it turns red. Which response is the scientific one?

Beginner
A Decide the shirt is ruined and throw the whole shirt away B Ask why soap changes the colour, and test whether lemon juice does too C Write the colour change down and never think about it again D Assume that somebody must have spilled red ink onto the shirt earlier on
Show answer & explanation

Ask why soap changes the colour, and test whether lemon juice does too

Noticing is only the start. Shaping it into a question and testing that question is what makes it science.

A shadow is short near noon and long in the evening, every day. Why does this interest a scientist?

Intermediate
A Because a repeated event is far easier to photograph than a rare one is B Because shadows are the only part of all nature that can be measured C Because anything happening daily must already be fully explained D Because a pattern that holds suggests a cause working underneath it
Show answer & explanation

Because a pattern that holds suggests a cause working underneath it

A pattern that keeps holding signals that a cause sits underneath, and that cause can be hunted down.
