1.Only thermal energy transfers; 'cold' is absence of thermal
energy
2.Temperature measures average kinetic energy; heat is energy
transfer
3.Metals conduct heat faster, so they feel cold by drawing heat from
your hand
4.Energy is conserved; it transforms between forms but total amount
stays constant
[!] STUDY GUIDE: Big Ideas
Use to answer form questions!
1.Heat transfers in THREE ways: conduction, convection,
radiation.
Each uses different mechanisms to move thermal energy.
2.Metals feel cold because they conduct heat FAST.
They quickly pull thermal energy from your warm hand - they aren't
actually colder!
3.Heat always flows from HOT to COLD. Thermal energy
transfers until objects reach the same temperature (thermal
equilibrium).

[?] THE PHENOMENON
Write BEFORE Hook form
Why do some materials feel cold to touch even at room temperature?
A metal desk and a wooden desk sit in the same room at 20C. When you
touch them, the metal feels much colder. But a thermometer shows
they're the SAME temperature. What's happening?

Final check before Science Circle+5 pts
Q1 (NEW):
A student says "Metals are naturally colder than wood." Is this
correct? Explain using heat transfer.
Q2 (SPIRAL W1):
Two objects at thermal equilibrium have the same ___. Does this mean
they have the same thermal energy? Explain.
Q3 (INTEGRATION):
Back to our phenomenon: Why does metal feel colder than wood at the
same room temperature? Use conduction and particle motion in your
answer.
