Light travels in a vacuum at 300,000 km per second (186,000 miles per second). Space does not have any light. We can see things in space due to light bouncing off of the objects in space. Infrared light has a wavelength that is too long for the human eye as well.

The process of photosynthesis converts light energy to stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen.

Light Facts

• 01Light is made up of energy.
• 02Light travels in a straight line.
• 03The speed of light is exactly 299 792 km per second.
• 04This is the speed when light is travelling in a vacuum and not obstructed by the atmosphere.
• 05Travelling at the speed of light, you could go around Earth 7.5 times in a second.

People and other animals can see because there is light. Light is a form of energy. The Sun is a very important source of light energy. Without the energy from the Sun, there would be no plants or animals on Earth’s surface.

The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space.

Facts about Gas Gas is essential to life on Earth. Oxygen helps produce energy in the human body, and carbon dioxide is used by plants for photosynthesis. Fire is formed from a combination of hot gases. Natural gases are lighter than air.

5 Ideas to Teach Light

1. Go on a Light Hunt. Students look around the room to find examples of items (mediums) that transmit, reflect, refract, and absorb light.
2. Hands-On Vocabulary Lessons. I adore these 2 lessons from my Hands-On Science Vocabulary.
3. Small Group Science.
4. MUST-HAVE Observation Stations.
5. Periscope Challenge.

Light is a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. Light is a kind of kinetic energy Which enables the human eye to see or make things visible. The energy is released in the form of a photon and more photons come out as the substance gets hotter.

3.1 identify a variety of natural light sources (e.g., the sun, a firefly) and artificial light sources (e.g., a candle, fireworks, a light bulb).

Since fireflies communicate using their light, you can sometimes attract them by using a flashlight of your own. Pay attention to the light patterns that the fireflies are emitting, and copy them by switching your flashlight on and off. Consider placing a blue piece of paper over your flashlight to turn the light blue.

Most of us have fond memories of catching fireflies or lightning bugs on warm summer nights. Many people kept them in jars—sometimes a jar full of fireflies can produce enough light to read by. If you want to catch fireflies, here are a few tips that will help you along.

Air holes dry out the air in the jar, and fireflies need damp air to survive. There is plenty of air in the jar to keep the insects alive for a day or more.

Take a look at six ways you can not only bring fireflies to your customer’s yard, but also make the yard a paradise for fireflies.

1. Let the grass grow.
2. Create a water feature.
3. Turn off porch lights.
4. Plant native trees.
5. Avoid pesticides.
6. Start a wood pile or add an extra one.

Whether you know them as Lightning Bugs or Fireflies, these are beneficial insects. They don’t bite, they have no pincers, they don’t attack, they don’t carry disease, they are not poisonous, they don’t even fly very fast.
