Top 10 science fair projects you can finish in a weekend
Every project on this list is one of Peabody's own, free, with the hypothesis, steps, results table and board plan on its page.
How it's ordered: Projects with two days of testing or less, the shortest sitting first.
The ten projects
- 🏀 Which ball bounces the most times? (ours): kindergarten · 1 day of testing · free. A bouncy ball squashes when it hits the floor and then springs back, and the spring pushes it up again.
- 🌤️ How does a shadow change through the day? (ours): 1st–4th grade · 1 day of testing · free. A shadow is the dark patch where the bottle blocks the sunlight.
- ☀️ Where does a puddle dry fastest: sun, shade or wind? (ours): 2nd–6th grade · 2 days of testing · free. Water dries up when its tiny bits get enough energy to leap into the air as water vapour.
- 🔦 Does a toy's shadow get bigger when the flashlight comes closer? (ours): kindergarten · 1 day of testing · free. A shadow is where the toy blocks the light.
- ✈️ Which paper goes farthest: a flat sheet, a ball or a plane? (ours): kindergarten · 1 day of testing · free. Air pushes back on anything that moves through it.
- 🚗 Does a higher ramp make a toy car roll farther? (ours): kindergarten · 1 day of testing · free. A car at the top of a higher ramp has farther to fall, so it is going faster at the bottom.
- ⛵ Sink or float: does a bigger foil boat carry more blocks? (ours): kindergarten · 1 day of testing · free. A boat floats when it pushes enough water out of the way to hold up its load.
- 🌉 Which paper bridge holds the most blocks: flat, folded once or folded like a fan? (ours): kindergarten · 1 day of testing · free. Flat paper bends easily in the middle.
- 🧽 Which soaks up the most: a sponge, a paper towel or a cloth? (ours): kindergarten · 1 day of testing · free. A sponge, a paper towel and a cloth are all full of tiny holes and gaps.
- 📄 Does crumpled paper fall faster than flat paper? (ours): 1st–4th grade · 1 day of testing · free. Air pushes up on anything that falls.
