Which of the following objects provides evidence that humans can make light sources?
Which of the following objects provides evidence that humans can make light sources?
A flashlight is a human-made object, so this gives us evidence or proof that humans can make light sources. The Sun and lightning are both natural sources of light, so nature, not humans, created them.

What illuminates this birthday cake?
The candles on the top illuminate this cake. From the picture, we can observe that the only source of light is coming from the candles, and without them, it would be dark. The background of the picture is dark, so there are no other sources of light.

Illumination is necessary to see objects in the dark. I tested this by looking into a dark room with no lights and a dark room with different light sources (candles, flashlights, and lanterns). When I used a light source, I could see what was in the room. When I did not use a light source, I could not see.
Is this statement evidence-based, or is it an opinion? How do you know?

To see objects in the dark, I must use a light source to illuminate it. I know this because I performed a set of investigations and collected data. The data showed that when I went into a dark room, and my brother held up a toy, I could not see what it was. When I used a flashlight, I could see the toy.

This is an evidence-bassed statement because there is no personal opinion mentioned, and the writer collected data to conclude. Using data is a form of evidence that helps support a conclusion.

Objects can be seen if a light is available to illuminate them or if they give off their own light.
Objects can be seen if a light is available to illuminate them or if they give off their own light.
This statement is true. Objects cannot be seen if it is dark. There has to be light from an outside source, or the object has to produce its own light to be seen.

Nancy cannot find her favorite shoes in the back of her dark closet. She grabs a flashlight and sees them! Why couldn't she find them before she turned on the flashlight?
Nancy cannot find her favorite shoes in the back of her dark closet. She grabs a flashlight and sees them! Why couldn't she find them before she turned on the flashlight?
Nancy could not see her shoes in the dark closet because humans cannot see when there is no light. The light must shine on an object and reflect into our eyes for us to see the object clearly, or it must make its own light. Shoes cannot make their own light, and the back of the closet was too dark for her to see.

What does the word illuminate mean? Example: I had to illuminate the dark cave to see if there was danger up ahead.
The word illuminate means to light something up. Humans have good vision, but we do not see well at night because there is limited light. Our eyes rely on light to reflect off the surface of an object so that we can see.

Which choice would be the BEST to illuminate a dark room?
Which choice would be the BEST to illuminate a dark room?
The best choice to illuminate (or light up) a dark room would be a lantern. A radio would give off little to no light, and a small candle would only produce enough light to see a few inches ahead of you. A lantern would give off much more light and help you to see in the dark.

Which object makes its own light?
Which object makes its own light?
A glow stick produces its own light. You can use a glow stick to illuminate a small dark area or to make yourself more easily seen at night time. Glow sticks make their own light when two chemicals are mixed after snapping or shaking the stick.

Bobby's teacher placed a secret object in a cardboard box and taped it closed. She poked small holes in the sides with a pen. She asked Bobby to look inside and tell her the secret object. He tried hard but couldn't tell what was in the box. What is the reason why Bobby couldn't see what was in the box?

Bobby couldn't see in the box because it was too dark! Tiny pinholes are not big enough to let enough light inside the box. If Bobby were to make larger holes or more holes, it would allow more light in to illuminate the object.

Lightning bugs use their internal light source to attract other insects. They might eat the other bugs that come to visit them, or if they are from the same species, they may become mates.

Why are you able to see these beautiful fish lanterns even in the dark?
Why are you able to see these beautiful fish lanterns even in the dark?
These beautiful oriental fish lanterns are visible in the dark because there is a light source inside of them illuminating the darkness. Humans must have light to reflect off of an object's surface for our eyes to process the image.

Which of these objects would illuminate a cave so we can see the objects inside?
The best object to bring into a cave would be the fire torch. This would illuminate or light up the area around you so that hidden objects (or dangers) would be visible. In the dark, without any light source, we would not know what is up ahead.

What would happen if you put a mirror in front of a laser light?
What would happen if you put a mirror in front of a laser light?
When a mirror is placed in front of a light source, it will reflect the light or cause it to be bounced back. If I were to shine a laser light on a mirror in front of me, the light would be reflected and appear on the wall behind me. Other objects may cause light to be blocked or will allow it to pass through, but a mirror will reflect it.

What would happen if you put a piece of plastic wrap in front of a flashlight?
If you put a piece of plastic wrap in front of a flashlight, there would be little change because the light would pass through. Plastic wrap is transparent and allows light to be seen through the other side. Other objects may block or reflect light, but something clear would allow it to pass.

If you tried to shine a flashlight through a sheet of black construction paper, it would block the light. Light would not be able to pass through to the other side, and it would not be reflected. Something dark in color and also a thicker material like construction paper would block light from passing.

If I were to place the chocolate bar in the Sun, it would melt due to the heat. The rays of light from the Sun are not only bright but hot. Chocolate is something that melts, and sitting under warm light would cause that to happen.

What makes a shadow?
What makes a shadow?
A shadow is created by blocking light. Shadows need a light source like a lamp, the Sun, or a flashlight and an object to block the light. A simple way to see a shadow is standing outside during the day and looking down! Your body blocking the sunlight will create a shadow of your figure on the ground. Another easy way to make a shadow is by putting your hands in front of a flashlight in a dark room.
