Living Creatures: Exploring their Characteristics
Class 6 · Science
4 ideas in Class 6 Science, explained in plain words, with games and quizzes to practise.
Characteristics of Living Beings
Part of: What sets the living apart
Living beings share a set of features: they need food, grow, breathe, remove waste, respond to things around them, reproduce and eventually die. A cow does all of these. A toy car may move, but it does not grow, eat or reproduce, so it is non-living.
Why it matters. Children often decide that anything that moves is alive, or that anything that stays still is not. Learning to check several features together builds careful scientific thinking.
Try it in two minutes
- Pick three things at home, for example a houseplant, a clock and a pet or a toy. Ask: which of these is alive?
- For each one, ask your child to give a reason using features such as growing, needing food, or having babies.
- Ask about a tricky case: a clock has moving hands, so is it alive? Let your child explain what is missing.
Try at home. Ask your child to make a two-column list of living and non-living things in the kitchen, with one reason for each.
Conditions for Seed Germination
Part of: How seeds germinate
Germination is when a seed sprouts into a young plant. For most seeds it needs the right amount of water and air. Soil that is damp but loose holds both. A pot flooded with water has no air for the seed, and dry soil has no water for it.
Why it matters. Children learn to link a cause to an effect, and they see why plants fail when watered too much or too little. It also explains how grains are stored safely.
Try it in two minutes
- Place a few soaked moong or chana seeds on a damp cloth in one plate and dry seeds in another plate.
- Ask your child to predict which plate will show sprouts and why.
- Look every day for three or four days and talk about what is different.
- Ask: what would happen if the seeds were buried in a bowl full of water?
Try at home. Ask your child to explain why a bag of dry wheat does not sprout in the store room, but wet wheat might.
Stimuli and Movement in Plants
Part of: Growth and movement in plants
A stimulus is anything that makes a living being respond, such as touch, heat or light. Plants cannot walk, but they respond too. A touch-me-not plant folds its leaves when touched, and the upper part of a plant bends towards light while its root grows down.
Why it matters. It shows children that being alive does not always mean moving about. It also trains them to notice slow changes and explain them by cause and effect.
Try it in two minutes
- Find a houseplant that sits close to a sunny spot near the glass pane. Ask your child which direction its leaves and stem are bending.
- Turn the pot around and look again after two or three days.
- Ask your child why the plant leaned towards the window, and what the stimulus was.
Try at home. Let your child sprout a gram seed on damp cotton, lay it sideways, and draw which way the root and the upper part bend over a few days.
Life Cycles of Plants, Mosquitoes and Frogs
Part of: Life cycles of plants and animals
A life cycle is the series of stages a living being passes through from the start of its life to making new ones like itself. A bean goes from seed to plant to flowers and pods with new seeds. A mosquito goes from egg to larva to pupa to adult. A frog goes from spawn to tadpole to froglet to adult.
Why it matters. Life cycles show that living things change a great deal as they grow. Knowing the mosquito cycle also explains why we must not let water stand around our homes.
Try it in two minutes
- Ask your child to draw four boxes and label the stages of a frog's life, starting with spawn.
- Do the same for a mosquito and ask: where do the early stages live?
- Walk around your home and look for places where water could collect and stand still.
- Ask: what can we do to stop mosquitoes from developing there?
Try at home. Together, empty and dry a cooler, bucket or plant saucer once a week, and talk about why this helps.
