The Backyard Is a Lab

You do not need fancy equipment for real science. These experiments use household items and teach biology, chemistry, and physics through hands-on discovery.

10 Backyard Experiments

Bug Hotel: Stack sticks, pine cones, and leaves in a container. Check weekly for insect residents.
Plant Race: Grow the same seed in sun vs. shade. Measure growth daily.
Soil Layers: Dig a small hole and observe the layers. Compare to a jar of mixed soil and water.
Rain Gauge: Cut the top off a plastic bottle, invert it, and measure rainfall.
Shadow Clock: Mark a stick's shadow every hour. Watch it rotate with the sun.
Compost Jar: Layer food scraps and leaves. Observe decomposition over weeks.
Bird Feeder Study: Make feeders with different foods. Track which birds prefer what.
Water Filtration: Layer sand, gravel, and coffee filters in a bottle. Pour muddy water through.
Leaf Rubbing Collection: Collect leaves, identify species, and create rubbings.
Evaporation Race: Place equal water amounts in sun, shade, and indoors. Track which disappears fastest.
