Most kids KNOW the info, but haven’t put in the vocabulary – and some just totally flub the idea of SUBTRACTING heat…they want to “add cold” which leads to a great discussion about heat energy (not cold energy). Cold is a descriptive word that describes the absence of heat energy.
I make the kids draw this chart out multiple times.

6. Demo – hand-warmer
Explain the hand-warmer demo Ms.Garris showed.

7. How long will the candle burn?
21% Oxygen in all Jars – but that equals a smaller amount of oxygen in a small jar
Largest Jar = ____ sec
Medium Jar = ____ sec
Small Jar = ____ sec

8. Hypothesis: (What do you think will happen?)
Candle demo
Dec. 7, 2017
Question: How does the amount of air affect how long a candle will burn?
Hypothesis: (What do you think will happen?)
Data: (Make a chart to record your burn times)
Trial 1
Trial 2
Trial 3
Average
Large Jar
Medium Jar
Small Jar
Conclusion: (Was your hypothesis correct? Why or why not?)

9. Mixture of Gases in Air All Other Gases Argon = 0.93%
Carbon Dioxide = 0.04%

10. How long will the candle burn?

Largest Jar = ____ sec
Medium Jar = ____ sec
Small Jar = ____ sec 2)
Largest Jar = ____ sec
Medium Jar = ____ sec
Small Jar = ____ sec

11. NITROGEN A major part of proteins, including DNA
Dilutes (thins out) the oxygen – too much or too little oxygen and we would die!
Turned into useful form
by nitrogen-fixing bacteria

12. OXYGEN Necessary to survive! Our cells use oxygen to create energy
All of the oxygen in our atmosphere has been created by plants – photosynthesis!
Burning requires oxygen

13. CARBON DIOXIDE Used by plants for photosynthesis
A greenhouse gas – carbon dioxide helps keep our planet warm
Increases in CO2 have been making the planet warmer: global warming!

14. TRACE GASES OZONE helps filter out the sun’s harmful rays
ARGON is used in light bulbs because it will not catch fire even in extreme heat
WATER VAPOR can condense to form clouds
HELIUM inflates balloons and
blimps

15. Why is the atmosphere important?
Has oxygen that living things need to survive.
Traps energy from the sun keeping earth warm
Protects living things from dangerous radiation from the sun.

16. Hot vs Cold lab
Put your lab set up onto white paper (it makes it easier to see)
Be ready to observe and RECORD your observations.

25. Making a foldable: Layers of the Atmosphere On the inside, include notes about each layer: ) How thick is this layer? ) What’s in the air here? ) What is the temperature? ) What happens here? *Use the textbooks (pg ) and the green “Weather & Water” books (pg. 9-11) to find the answers. *Decorate the outside with pictures of what happens in each layer.
Layers of the Atmosphere
400 km
Thermosphere
80 km
Mesosphere
50 km
Stratosphere
12 km
Troposphere
0 km

26. TROPOSPHERE Thinnest Layer (0-12 km)
Average Temperature of 25°C (Temperature drops as you go higher)
All of Earth’s weather happens here.
Air here contains water & dust.
Most of the atmosphere’s air is here (this layer is very dense).

27. STRATOSPHERE 10-50 km above earth’s surface
There is almost no water or dust in this layer.
Contains the OZONE LAYER (which absorbs UV radiation from the sun)
Very cold, until the top of the layer, where it warms to 0°C.

28. MESOSPHERE 50-80 km above Earth’s surface.
Temperature plunges to -90°C (the coldest in the atmosphere)
Meteors burn up here while entering the atmosphere.

29. THERMOSPHERE Thickest layer (80-400 km above Earth’s surface).
Air is extremely thin. Atmospheric gases fade into outer space.
Temperature can spike to 1,800°C.
