for Rainbow Day
The students will explore Sir
Isaac Newton as the scientist who discovered the spectrum of light and
create a timeline of scientific discoveries and inventions.
- Read the book or share
information off a website regarding Isaac Newton as an important
scientist in our history. Specifically discuss how he
discovered white light is composed of all the colors in the
spectrum. He did this by using a prism and sunlight.
- Discuss how many important
discoveries and inventions occurred throughout history. Isaac
Newton discovered the spectrum in 1666.
- Work as a class to create a
timeline featuring other important discoveries. Use the
following link for reference; http://www.crimsonbird.com/science/timeline.htm.
The detail of the timeline will depend on the age of the
children. For example younger children may just
need 4-5 points on their timeline - 1. 1500's a scientist discovered
that the planets revolve around the sun, 2. 1600's Isaac Newton
discovered the spectrum of light, 3. 1700's the hot air
balloon was invented, 4. 1800's the steam boat was invented, 5.
1900's the first airplane took flight. Older students may
include more dates on their timeline. For younger students
this will be a more general lesson on what a timeline is and what it
- Have a lesson on Hawaii, where rainbows occur more often than
other parts of the country, due to its climate.
- Discuss rainbows and how they play a part in various
folklore. A good variety of these are discussed in the book The
Rainbow and You by E.C. Krupp.
