Fill the jar halfway with cream, and add the marble. 2. Make sure the jar is tightly closed, and start shaking it. You don’t have to shake hard or fast, just about once per second. Do you hear the marble rattling? 3. After a few minutes, whipped cream will coat the sides of the jar. Keep shaking.…

Corn is the number-one crop in the United States. Farmers plant trillions of corn seeds every year. Most cornstalks grow only one or two ears of corn.

Big, little, bumpy, smooth, hard, soft. Seeds can look different on their outsides. But inside every seed waits a baby plant, ready to grow. Every little tomato seed is protected by a strong outer coat. Moisture and warmth soften the coat, so a thin white root can push through. When the seed is planted, more roots grow and spread down through the soil. A little stem pushes out of the seed coat too. It pokes up out of the soil, looking for light. Two seed leaves open. They formed inside the seed to feed the baby plant until it can make its own food. You can still see the seed coat covering the seed leaves on one of these plants. Soon the plant grows its true leaves. This plant still…

Pineapples grow from spiky plants that look a bit like a pineapple fruit’s top crown. Each plant grows only one fruit and then slowly dies. But first it sprouts new shoots that grow into new plants. Originally from China, kiwifruit are also known as Chinese gooseberries. Growers in New Zealand renamed the fuzzy, brown fruit after New Zealand’s beloved fuzzy, brown bird, the kiwi. Some cucumbers have thick, smooth skins and big seeds. Some have thin skins and just a few small seeds. Cucumbers used to make pickles are often short with thin, bumpy skins. A grapefruit’s color depends on its type. The peel can be yellow, green, pink, orange, or a blend. The color of the juicy center ranges from yellow to pink to red.…
