- 1. The library
- 2. The hospital
- 3. The market

Before you start
A leaf, close up: its blade, its veins and the stalk it hangs by.
- 1. The veins

- 3. The leaf's edge
The pale lines running out through a leaf are its veins, and different plants arrange them differently — some spread out like this one, others run side by side down the length of the leaf. Rub a crayon over paper laid on a leaf and the pattern comes up like magic.

Beaks, claws and fins
Read an animal's body like a set of tools: work out from a beak, a claw, a snout or a foot what its owner eats and where it gets about.
Before you start
A turtle in the shallows, with its shell, its head and its spread feet.
- 1. The shell
- 2. The webbed feet
- 3. The head
Two different jobs, two different parts. The shell is armour and does nothing to help the turtle move; the feet are spread and joined by skin, which pushes far more water than a bare foot would.

Class 4 The World Around Us · 6 of 12
Growing up with nature
Follow a natural dye from a handful of flowers to a coloured cloth, say how a village builds, stores and doctors itself out of what grows nearby, and match three festivals to the living things they honour.
Before you start
Two containers for storing grain, standing ready in the corner of the house.
- 1. The earthen pot
- 2. The bamboo basket
Look closely and neither container is bare. One of them is lined with leaves on the inside; the other has been coated right round the outside. Neither is decoration — both are there to keep something out of the grain.

Food for health
Sort everyday foods into the three groups the chapter uses, work out how much of each belongs on a plate, and match the six tastes to the things that carry them.
Before you start
A plate laid out the way the chapter describes a balanced one, in three parts of three different sizes.
- 1. The largest part
- 2. The middle part
- 3. The smallest part
Three groups, three different amounts of room. The chapter is quite clear about the order — one group takes the most space, one comes next, and one is meant to be there in small amounts rather than piled up.

Write the number of the part.
2.Why does the chapter say we need to eat a variety of foods?

Happy and healthy living
Name who and what a grain passes through before it reaches your plate, walk through eating one mouthful mindfully, and say what the chapter asks you to do when a touch feels wrong.
Before you start
Three things a day needs: a good plate, something that gets you out of breath, and a proper night.
- 1. The plate of food
- 2. The skipping rope
- 3. The bed
The chapter spends a page on each of these three and then says something surprising: they are not ranked. One of them is often treated as what you do when there is nothing else left to do, and the chapter refuses to treat it that way.

5.In the mindful eating exercise the teacher placed one small food item on each child's palm, and some of them knew it by touch alone. What was it?
6.Match each habit to what the chapter says it does for you.
- Running and skipping
- Yoga
- A good sleep
- Takes away tiredness and makes us feel fresh

- Keep us strong and energetic
7.What does the chapter say mindful eating is?

The same square of aluminium foil, three times over, in three different shapes.
- 1. Spread out flat
- 2. Folded into a cup
- 3. Pressed into a ball
Nothing has been added and nothing taken away — it is one piece of foil, weighing the same in each of the three pictures. The shape is the single thing that changes between them, and the water does not treat the three the same way.

Before you start
Three kinds of paper, seen from the side so their thickness shows.
- 1. The left sheet
- 2. The middle sheet
- 3. The right sheet
Paper is not one material. Seen edge-on, these three are nothing like each other, and what each of them is good for follows from that — how thin it is, how soft it is, and whether it soaks up water or holds its shape.
