Astrophysics:
Fly through the universe in 3-D, faster than light, through the
Milky Way! Make your own comet and learn how astronomers see far,
far away – EXPLORE THE UNKNOWN! |
Fingers get cold in dry ice |
Wear gloves |
Electronics 2:
Build an electronic voice monitor! Stuff and solder
a pc board, mount IC’s (integrated circuits) and assemble the unit.
After assembly, monitor your voice volume with the LEDs. What does it say– WISE
GUY! |
You
could burn yourself or solder can “pop” into and damage your eye
|
Always pick up a hot soldering iron
ONLY by the handle; keep the tip and the metal barrel away from
fingers, skin, clothing, and anything else that can get burned; put
the iron back in the holder |
