The object that would be most appropriate for investigating light reflection would be a mirror. Mirrors reflect images and light, whereas paper and clothing absorb light. Using a mirror would allow someone to shine a light on the mirror and record how it reflects and study why.

The best object for investigating light passing through a material would be the plastic wrap. All of the other answer choices would either reflect or block light from passing so they would not help with this investigation. Plastic wrap is clear and would allow the light to pass through.

If Matt is wondering what makes shadows beside the flashlight, he needs to explore other light sources. Looking around inside and outside will give Matt other light sources and views of shadows. Keeping recordings of the investigation will provide Matt the data and evidence he needs to make a conclusion.

The best plan for an investigation into how and why people block like would be to research online and then view with his eyes examples of light being blocked. He could record what he sees on the walk, in his own house, and the reasons online that he finds to answer his questions.

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.

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.

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.

Light travels in waves outwards from its source. Light travels in a straight line. It can be altered when it is absorbed, refracted, or reflected.
