Making Lightning
Objectives:
To bend electricity in order to make lightning
Materials
Rubber glove
Plastic fork
Tin Foil
Wood or lastic cutting board
Styrofoam late or rubber balloon !ead of hair or "ool
#ool, lo"$humidity day %& '() humidity, & *( F temerature+
Procedure
- Fold tin foil around your lastic fork so that it looks like a bigsatula- Make sure it.s as /at as ossible "ith no shar
corners-0- Put on the rubber glove and use your gloved hand to rub the
Styrofoam late or rubber balloon on your hair or "ool-
1- Place the late or balloon on your cutting board, and use thegloved hand to ick u your tin foil satula-
'- Place the tin foil art of your satula on the balloon or late-Touch the foil "ith your other hand- What happened? Ho canyou e!plain hat you sa?
(- Pull the satula u from the balloon or late, and touch itagain- What happened this ti"e? Did you e!pect that?
2- 34eriment "ith other materials- Recharge your chargedob5ect using your hair or "ool if necessary- Does your handspar# hen it touches the balloon? Why do you thin# this is so?

Homemade Batte y
Objective:
to kno" ho" a battery "orks
to make other uses of everyday things
Materials:
A lemon, or other citrus fruit
6 %or smaller+ gauge coer "ire
Wire strier7clier
A gro"n$u or older friend
Steel aer cli, small galvanized nail %one that is covered in 8inc+, or a iece of 8inc
%ideal+
Procedure
- Ask your gro"n$u to use the "ire striers to 9rst stripabout 0 70 inches of lastic
insulation o: the coer "ire- Then, re;uest that the gro"n$u clipthat iece of stried
"ire o: of the main roll-
0- #arefully straighten the steel aer cli- f they are toofar aart, the matter might lose their "ay-
6- This time, touch your moistened tongue to both "ire ends- What do you notice?
Results
When you touched your tongue to 5ust the coer "ire, you most likely "ould not have noticed
anything unusual- When you touched your tongue to ?@T! of the metal ends, you might have
felt a tingle, or noticed a metallic taste-

Magnetism from Electricity
>n 60, the Banish hysicist !ans @ersted %***C6(+ noticed that acomass needle "as de/ected at right angles to a "ire carrying an electriccurrent- Since a comass needle is de/ected by a magnet, he concluded
that the electric current someho" caused a magnetic 9eld around the "ire-Further studies by @ersted roved that any "ire carrying an electric currenthas a magnetic 9eld around it- @erstedDs discovery started the study ofelectromagnetism and the use of an electromagnet %device that uses anelectric current to roduce a concentrated magnetic 9eld+-
>n this ro5ect, you "ill determine the direction of a magnetic 9eld around acurrent$carrying "ire- =ou "ill determine the e:ect of the direction of anelectric current in a current$carrying "ire on the attern of the magnetic
9eld around it- =ou "ill also make an electromagnet, determine its olarity,and test its strength-
Objective:
To determine the direction of a magnetic 9eld around a current$carrying"ire-
Materials
encil ruler
sheet of coy aer
comass
-($volt B battery
"ire strier

'- First rotate the comass so that E on the comass is in line "ith theneedle ointing north- Then lift the comass and rotate the aer sothat its comass directions match those on the comass- Relace thecomass on the aer-
(- Place the battery on the east side of the aer, "ith the negativeterminal of the battery ointing south-
