Leonardo da Vinci: The Scientist
Did you know the artist who painted Mona Lisa was also an impressive scientist? This is part 2 of a 3 part hands-on unit study on Leonardo da Vinci: The Artist, Scientist, & Inventor. This lesson will cover his work as a scientist. Build a working hydrometer and hygrometer, begin a nature journal, write notes in a secret code, and more! These lessons are geared toward 3rd-4th grade level children and their siblings. They were created by another creative teacher for a weekly homeschool co-op. We meet each week for 2 1/2 hours and have 16 children between the ages of 1-13. Use these fun lessons with your classroom, family, or homeschool co-op group!

Lesson Plan on Leonardo da Vinci: The Scientist
1. Pray. Read Proverbs 20:12.
2. Introduce Leonardo da Vinci as a scientist. Emphasize how he used his eyes to observe things rather than blindly accept what the Greeks & Romans taught.
3. Have children close their eyes. Rearrange 5 items in the room. Have children open their eyes. Can they tell what has changed? Were they attentive to detail like Leonardo da Vinci?
4. Read some of Leonardo da Vinci: Dreams, Schemes, and Flying Machines by Heinz Kuhne, focusing on his scientific discoveries and observations.

5. Show the painting of Lady with an Ermine (Portrait of Cecilia Gallerani). Briefly explain how Leonardo da Vinci made many observations about how light works (called optics) and applied it to his art.
6. Get 2 volunteers to demonstrate. Have one child hold a flashlight and shine it from various angles toward the side profile of the second child. Ask the children what they observe and the light and the shadows.
YOU WILL NEED: a flashlight
7. Explain that a hygrometer is an instrument used to measure the humidity, or amount of moisture, in the air. Many people credit Benjamin Franklin or Horace-Bénédict de Saussure for this invention, but Leonardo da Vinci actually invented a hygrometer a couple hundred years before they did. We gave each child 2 plastic drinking cups with 2-3 holes punched through the top so that we could string yarn through them. One cup had the bottom covered in wax (done by dripping melted candle wax into it). The children attached the cups to each side of a wire hanger, looping it over and tying it through the holes. We used tape to match sure 1 cup stayed on each side. We placed 3 cotton balls in the cup without the wax. This can show how much humidity is in the air because the cotton balls will fill absorb water. That cup will show itself to be heavier when there is more moisture in the air.

YOU WILL NEED: candle, lighter/matches, hole punches, wire hanger (per child), 2 plastic cups (per child), yarn, scissors, & 3 cotton balls (per child)
8. Hydrometers are used to measure the density of water. They are especially important in the shipping industry when ships sail into different bodies of water. Leonardo da Vinci designed the first hydrometers. We will create simple models. Pair up children into groups of 3. Give each child a straw, a small ball of clay or play-dough, and a small nail that can fit inside the straw. Give each child a glass of water. One glass should have regular tap water. Another glass should have slightly salty water. The third glass should have extremely salty water (made by boiling the water and then stirring in lots of salt). Emphasize that all 3 glasses contain water. Have each child place the ball of clay on the bottom of the straw and then drop the nail down into the straw. This is your hydrometer. Each child should place their hydrometer in their glass of water. Have them compare how high or low their hydrometer floats compared with the other children's in their group. A less dense liquid will allow the hydrometer to sink lower. You can also compare cold and hot water. To find out more information, go to www.ecawa.asn.au.
YOU WILL NEED: (per child) a straw, nail, ball of clay/play-dough, a glass, & salt
Writing Backwards/Mirror Writing
9. Leonardo da Vinci wrote his letters backwards in his notebooks. He may have done this in order to not smear the ink since he was left-handed and/or as a "secret code" to deter others from stealing his ideas. Attempt to write backwards by using the Mirror Book that can be printed from dynamic2moms.webs.com. Have children write something and then use a mirror to check to make sure they wrote it correctly. Some children found it helpful to practice on a sheet of scrap paper first.
YOU WILL NEED: mirror pages from dynamic2moms.webs.com (optional), writing utensils, & compact mirrors
10. Leonardo da Vinci learned so much for careful observation, and he was forever making detailed drawings and notes on whatever he observed. Pass out a spiral notebook to each child. Give them a few minutes to design the front cover. If desired, give a short lesson on how to add shadows and shading in with a pencil. You can get ideas on what to do and show from www.artinstructionblog.com. Then head outside and tell them to find something outside. Have them draw as much detail as they can. If you are not limited by time, have the children exchange notebooks and try to identify what the other child drew. If the weather is bad, have the children sit next to a window to draw something outdoors.
YOU WILL NEED: (per child) spiral notebook and pencil plus items for decorating the cover of the notebooks
11. Five minute review of what we learned.
