CRITICAL THINKING ACTIVITY: THE METHANE CYCLE
It is the main component in natural gas. Methane is considered the simplest of alkanes, compounds that consist only of hydrogen (H) and carbon (C) elements. Methane is an odorless, colorless, tasteless gas that is lighter than air. When methane burns in the air it has a blue flame. In sufficient amounts of oxygen, methane burns to give off carbon

If the temperature is high, the body sweats in order to cool down. Since the process of sweating is done to stop the temperature change, this is a negative feedback.

LAB ACTIVITY: HEAT, TEMPERATURE AND CONDUCTION
gml.noaa.gov2 Student Sheet 2 Cooling things by conduction works the same way as warming. This time, a hot metal spoon is put in room-temperature water. The faster-moving atoms in the spoon contact the slower-moving molecules in the water. The atoms in the spoon transfer some of their energy to the molecules in the water. The spoon will get
TEACHER BACKGROUND: SPECIFICS OF HEAT TRANSFER
gml.noaa.govIn a new scenario, a metal can containing hot water is placed in a Styrofoam cup containing cold water. Heat is transferred from the hot water to the cold water until both samples have the same temperature. The transfer of heat from the hot water through the metal can to the cold water is referred to as conduction.

TEACHER BACKGROUND: NATURAL CLIMATE CHANGE
gml.noaa.govmeans cooler summers and milder winters. Slow changes in the Earth’s orbit lead to small but climatically important changes in the strength of the seasons over tens of thousands of years. Climate feedbacks amplify these small changes, thereby producing ice ages. Solar variations - The Sun is the source of energy for the Earth’s climate system.
