The Science behind Fireworks

Have you ever wondered how fireworks get their color? Today, we will be investigating how scientists are able to use the light waves emitted by different substances to create a colorful fireworks display.

Video #1 - Heating Chemical Samples

• Today, we will be taking observations of light emitted by different chemical samples.

• These chemicals are extremely useful in creating different color combinations in fireworks and other light displays.

• During the video, think about the characteristics of each light wave! Is each light wave the same? Or do they have different properties?

Multiple Choice

Each chemical substance in the video emitted identical waves:

• True

• False

Each chemical emits unique waves

• In the video, each chemical sample emitted a different color of visible light.

• Depending on the chemical, the waves emitted had unique wave properties.

• Based on the frequency/wavelength of the wave, we perceive the color of light differently.

• Scientists use these chemicals to create unique color combinations in fireworks displays

Multiple Choice

Calcium emits orange light and Strontium emits red light. Which substance emits waves with a longer wavelength?

• Calcium, because orange light have a longer wavelength than red light

• Strontium, because red light have a longer wavelength than orange light

• Neither, because orange light has the same wavelength as red light

Multiple Choice

Barium emits green light and Strontium emits red light. Which substance emits waves with a higher frequency?

• Strontium, because red light have a higher frequency than green light

• Barium, because green light have a higher frequency than red light

• Neither, because green light has the same frequency as red light
