Video · 1:46 · Crafty Clover explains, from A Million Whys Book 29

Place ten seeds on a damp paper towel, fold it, and slip it into a plastic bag. Keep it somewhere warm and check each day. After a week or so, count how many sprouted. If seven sprout out of ten, that's 70 percent. If very few do, buy fresh seeds or plant extra. Seeds lose their liveliness with age, and storage conditions matter.

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How can you test whether old seeds will still sprout?

The Big Idea

You found an old packet of seeds! Will they still sprout? Let's test them.

The Setup

Step one: The Setup. Place ten seeds on a damp paper towel, fold it, and slip it into a plastic bag. Keep it somewhere warm and check it each day.

Counting

Step two: Counting. After a week or so, count how many seeds sprouted. If seven out of ten sprout, that's 70 percent.

Decide

Step three: Decide. If very few sprout, buy fresh seeds or plant extra. Seeds lose their liveliness with age, and how they are stored matters.

A Closer Look

Let's take a closer look! Easy math. Keeps them moist. Helps sprouting. Find the percent.

Quick Facts

Quick facts! Seeds last longer when they are kept cool and dry. Ten seeds are easy math. Seven of ten is 70 percent. Seeds age over time.

Think Like a Scientist

Now, think like a scientist! Put ten old seeds in one damp towel. Put ten new seeds in another. Seal each in a bag and keep them warm. Count the sprouts after a week. Which packet had the higher percentage?

Outro

To test old seeds, put ten on a damp paper towel in a plastic bag, keep it warm, and count the sprouts after a week, so seven out of ten means 70 percent. If few sprout, buy fresh seeds or plant extra. Science is amazing! The world is full of surprises. Keep asking big questions, and keep exploring with me!
