Fifth grade students did this experiment in science class. They set up three identical notecards with the same size hole in each card and lined up the holes on each card. The last card did not have a hole in it. They turned off the lights and shined a flashlight at the first card and tracked where the light ended up on the last card. What property of light were the students investigating?

• Light can be reflected by mirrors and other shiny surfaces.

• When light travels through a lens it is refracted.

• Light travels in a straight line.

• Light can be separated into different colors.

What is the main reason this straw appears broken?

• The water acts like a mirror.

• Light does not travel through water, so the straw looks bent.

• Light changes speed and direction when passing through different materials.

• A wet object reflects light differently from a dry one.

When you stand on a step inside a swimming pool, your feet appear larger. This is because –

• light travels in waves.

• light is refracted by the water.

• light is reflected by the water.

• light is focused by the water.

A prism is a tool that separates light into all of its colors.It does this because as light passes through the prism it is –

Students set up the following experiment. They painted two identical cans, one white and one black. They suspended a thermometer inside each can and set them outside in the Sun. They recorded the temperature inside the cans every hour for three hours. What property of the cans would help explain why the temperature is higher in the black can after 3 hours than the temperature in the white can?

• Light is reflecting off of the black can and causing the temperature to rise.

• The white can is absorbing more light energy.

• The black can is absorbing more light energy.

• When light refracts off the black can, it causes the temperature to rise.

10. A fifth grade student read that shadows are longer in the winter. He decided to investigate to see if it was true. Which of the following investigations would give him the most reliable results?

• Put a stake in the ground and measure its shadow every day during the winter to see if it changes.

• Measure his shadow for the entire school year at the same time every day to see if it changes.

• Measure his shadow for the entire school year at the same time every day to see if it changes.

• Look at pictures taken at different times of year to see if the shadows look longer in the pictures taken in the winter.
