Kids Corner: Interesting crab facts
If you spot a crab, the first thing you might notice is the way it moves. But do you know why these curious crustaceans walk to the side instead of forward?
Crabs scuttle sideways because their shells are wider than they are long. As a result, they can’t fully extend their legs. In addition, crabs have five pairs of limbs that are close together, making it impossible for them to move backward and forward. Consequently, because of their unique anatomy, crabs have no choice but to walk sideways.
Nevertheless, crabs are surprisingly fast and can reach speeds of up to 7 miles per hour or more. Therefore, you’d probably lose if you ever got into a race with one.
Finally, crabs have a very useful superpower. If they lose a leg, it’ll eventually grow back.
How are rainbows formed?
Rainbows are beautiful optical illusions. Have you ever seen one before and wondered how they’re made? Here’s a quick explanation.
Although sunlight looks clear, it’s a blend of many different colors. A rainbow is created when white light enters a water droplet and splits into many colors. This happens because the water scatters the light waves through a process called refraction. The pattern of colors starts with red on the outside and chan¬ges through orange, yellow, green, blue, indigo, and violet on the inside.
The rainbow effect can be seen when water drops are in the air, like after a big rainstorm or near a waterfall. If you want to see a rainbow, your back must be to the sun. The lower the sun is in the sky, the higher the rainbow’s arc will be.
Keep your eyes out for a rainbow in the sky next time it rains.
Spring craft: an egg carton garden
Do you want to learn about where your food comes from? Planting an egg carton garden is a great place to start.
Here’s a list of what you’ll need:
• A cardboard egg carton
• A pair of scissors
• A pencil
• Good-quality potting soil
• A spray bottle
• A plastic bag
• Vegetable, herb, or flower seeds
Follow these steps to start your very own garden:
1. Cut the lid off an egg carton with scissors
2. Poke a drainage hole in the bottom of each egg cell using the tip of a pencil
3. Place the egg carton lid under the bottom to create a drainage tray
4. Fill each egg cell about half full of potting soil
5. Drop two or three seeds into each cell
6. Cover the seeds with a thin layer of potting soil
7. Write directly on each egg cell to keep your seeds organized
8. Mist the seeds lightly with a spray bottle
9. Place the carton in a plastic bag to keep the seeds warm
10. Water the seeds regularly until they sprout
11. Once the seedlings are about an inch tall, place them in a sunny location
When the seedlings have two or three sets of leaves, ask your parents to help you transfer them to a permanent location outside. Separate each egg cell and plant them directly in the ground with the seedling. The cardboard will decompose in the soil.
All that’s left to do is watch your seedlings grow into mature plants.
10 fun facts about bumble bees
Bumble bees are large yellow and black flying insects that harvest nectar and pollen from flowering plants. They play an important role in keeping the world’s ecosystems healthy. Here are ten interesting facts about this hardworking insect.
1. Bumble bees have extremely fast metabolisms and must eat almost continuously.
2. Bumble bees use buzz pollination. They place their upper body close to the inside of the flower and rapidly vibrate their flight muscles, producing a strong vibration. This shakes the pollen-free.
3. Bumble bees have two stomachs: one for eating and one for storing nectar.
4. Unlike honey bees, bumble bees can sting more than once because their stinger is smooth, not barbed.
5. Bumble bees have five eyes: two large eyes on either side of their heads and three eyes on the top of their heads.
6. Bumble bee colonies die in late fall except for new queens, which hibernate underground over the winter.
7. Bumble bees beat their wings 130 or more times per second.
8. Bumble bees get their name from the word bumble, which means to buzz, hum, or move about awkwardly.
9. Bumble bees are covered in a layer of oil that makes them resistant to water.
10. The largest bumble bee species can grow to an inch and a half long.
