Although it isn't hard to make, there are lots of pieces, so I'll photograph them carefully.
This lesson would also go really well with The Stuff of Stars by Marion Dane Bauer (which I would read beforehand) and The Photographic Card Deck of the Elements: With Big Beautiful Photographs of All 118 Elements in the Periodic Table by Theodore Gray (which I would do afterwards, looking at all of the element cards and laying them out to form the periodic table).
In Waldorf, a study of Chemistry begins in grade 7. So if you didn't do this lesson in Astronomy, I would definitely suggest it for the beginning of Chemistry and the Elements. A wonderful book of science experiments for the elements in grade 7 is The Book of Ingeniously Daring Chemistry: 24 Experiments for Young Scientists by Sean Connolly.
write the symbol for each on its tile on both sides with a sharpie
here are her colors and the diameter of the circles
Hydrogen - yellow - cut eight 8" circles
Helium - orange - cut seven 7" circles
Carbon - purple - cut six 6" circles
Oxygen - green - cut five 5" circles
Neon - dark pink - cut four 4" circles
Magnesium - blue - cut three 3" circles
Silicon - red - cut two 2" circles
Iron - black - cut one 1" circle
alternatively, a child familiar with the lesson can try to lay out the steps in order and then flip them over to if he/she is correct
it's a long presentation so I would allow at least 8 feet of space
for everything to fit in the photo I had to put my supernova below which is not ideal... I just did this for the photograph and would have it all in one long row for the students... it is important that they see it is a linear progression
I realize that some of the most-recently discovered elements were artificially created in the laboratory by scientists, but I would not go into that at this time... the idea here is that it is an impressionistic lesson which deeply affects the child in a hands-on and visual way, and those more abstract details can be addressed in grade 7 during a study of the atom and its parts
