Decay and Dice

Enable students to

1.	Relate radioactive decay to dice shaking
2.	Understand the meaning of “A ∝ N” and “k”

Apparatuses

Included in package

1.	Chart plate	x 10
2.	Dice shake (multi- or single-deck)	x 10
3.	Spare parts	x 1
4.	Worksheet file (read only)	x 1
5.	Presentation file (read only)	x 1
6.	Spreadsheet file (read only)	x 1

Not included in package

7.	Felt pen (water soluble)	x 10
8.	Forceps (for picking up dice)	x 10
9.	Tray (for holding dices)	x 10
10.	OHP	x 1

In a double-lesson, teachers could

1.	Draw students’ attention to the short- and long-term features of typical radioactive decay
2.	Pave the way of using dice model for simulating radioactive decay
3.	Allow students to use the dice model and collect data, sharing by OHP projection
4.	Interpret data from individual groups (more likely by aggregated result using the spreadsheet file)
