CO2 Experiment

This experiment went well the last time.

My first attempt failed. There was not enough CO2 transferred. I know this because the matches did not go out. The matches stayed lit because it feeds on O2. CO2 smothers the fire.

The second and third experiments were a success because we shortened the straw. This transferred more CO2 to the glass successfully.

The experiment was making CO2 for my earth atmosphere/greenhouse because there is plant life inside.

We used:

1. Baking Soda

2. Vinegar

3. Cup with a lid and hole (for straw)

4. Straw

5. Glass to transfer and observe CO2

6. Matches to prove CO2 presence and density

Atmosphere Observation

So far the Aloe plant is almost dead.

But the grass has grown 7.5 inches.

My hypothesis is still the same. The grass is taking most of the resources.

Also I think that since the plant is still in a cup it can not absorb most of the nutrients it needs.

Nov 24 Observation - Hypothesis

My guess is that what is happening is that the outer core water is evaporating.

I know this is because I saw not only water going up but bubbles inside of the water and in the tube from the outer core.

And then the water that we sprayed, due to density - is more dense then the dirt SO the water sank deeper into the crust, into the Moho

The Moho is the part of the crust that is between the upper crust and mantle.

Atmosphere Observation

We are one week after making the earth/greenhouse and life is doing well except for the Aloe plant.

I have felt and observed the Aloe plant and it is dry and going stiff.

My hypothesis is that since the grass is 1.5 inches tall, the grass is absorbing more CO2 then the Aloe plant.

I have also noticed that there’s water in the areas that I did not put water in - like the mantle/rocks and sand.

One more observation - the deeper you get into the crust/dirt the more moisture you find.

Stratosphere & Mesosphere

Journal Entry

The planes fly at what we call the stratosphere.

In the Stratosphere, you find an important layer of gas called the Ozone.

The Mesosphere is only accessible by Rocket.

Driving Question

My Driving Question - how is the Earth’s Atmosphere created?

I will answer this question by making an atmosphere myself, by researching and watching documentaries. The materials I am going to use are:

1. Gravel and Heater - core

2. Orbies (super-absorbent polymers) - inner core

3. Sand - outer core

4. Sand - Mantle

5. Soil - Crust (MOHO)

6. CO2 - Mesosphere

7. Spray bottle - Rain

Just a review, these are the layers of the earth:

1. Crust

2. Mantle

3. Outer Core

4. Inner Core

I hope the living organisms live through the experiment.
