Environment
Environment projects for class 1 to 5: 14 ideas.
Each project below opens to its own page with what it shows, the science behind it, the materials, safety, step-by-step instructions, what you should see and viva questions. Many can be made from things at home; where a kit helps, the page links one.
Other subjects for class 1 to 5: Physics, Chemistry, Biology, Maths, Earth and space, Electronics and robotics, Computing and coding.
Plastic bottle bird feeder
Waste plastic can be reused instead of thrown away, and a feeder lets you observe local birds. Keep a diary of which birds visit and when.
Food chain and food web model
Energy passes from plants to plant-eaters to meat-eaters. Taking one living thing out of the web affects all the others.
Four-bin waste sorting game with 40 picture cards
Household waste belongs in different bins: wet kitchen waste for composting, dry recyclables, hazardous items like batteries and medicines, and sanitary waste. Sorting cards into four coloured bins teaches the habit and shows how little should really go to a landfill.
What rots and what does not: a six-week burial test
Natural materials such as peels, paper and cotton are broken down by soil organisms within weeks, while plastic, foil and glass stay unchanged. Burying samples and digging them up shows which waste is biodegradable and which will stay in a dump for centuries.
How much water a dripping tap wastes, measured and scaled to a year
A tap that drips once a second seems harmless, but catching the drips for ten minutes and multiplying up shows it wastes thousands of litres a year, enough to fill a water tanker. Measurement turns a small leak into a number people act on.
Bucket versus running tap: measuring water used for daily tasks
The same task, such as brushing teeth, washing hands or washing a plate, uses many times more water when the tap runs than when water is taken from a mug or bucket. Measuring both ways gives the family hard numbers for saving water.
Biodiversity diary of one square metre kept for a month
Even one square metre of garden or wasteland holds dozens of kinds of living things: grasses, weeds, ants, beetles, spiders, snails, birds that visit. Watching the same patch daily and recording every species shows how rich ordinary ground is and how it changes with the weather.
Gravity-fed bottle bird feeder that refills itself
Seeds fall under gravity to fill a small tray as birds eat them, so the feeder keeps itself topped up. It shows gravity and also helps garden birds in the hot summer.
Newspaper roll pencil stand
Old newspaper can be turned into something useful. Reusing paper saves trees and reduces waste.
Bottle cap mosaic picture of a fish or a flower
Plastic caps can be reused to make art. We sort by colour and see how many small parts make a large picture.
Egg carton flowers and a crawling caterpillar
Waste egg cartons can be turned into toys and decorations. A caterpillar model also shows the first stage of a butterfly.
Old sock puppet family for a storytelling show
Old clothes can be reused instead of thrown away. Making puppets and telling stories also builds speaking and imagination.
Newspaper gift bag to replace plastic bags
A strong paper bag can be folded from old newspaper, which cuts down use of plastic bags. Folding and gluing teach geometry too.
Plastic bottle hanging planter for a small herb
A waste bottle can hold soil and a living plant. Drainage holes let extra water out so roots do not rot.
