It's a chocolate-based introduction to the rock cycle!
Like rocks, chocolate can be squeezed, heated, cooled, and weathered into tiny particles. Chocolate can go through these processes safely and at normal temperatures, unlike rocks.
Create "sedimentary," "metamorphic," and "igneous" chocolate using your supply of chocolate. Make a wonderful treat at the end of it all!
Materials:
Blocks of white and dark chocolate Cupcake liners made of aluminum foila container to hold the hot watera plastic knife or another straightforward scraperMaking "sedimentary" chocolate first:
1. Scrape a few tiny pieces of chocolate from your blocks.
2. Place all of these scrapings on a piece of aluminum foil and push down. You could press the chocolate shavings onto the aluminum foil after folding it. You may even stand on foil packets that were sealed.
3. Note how the consolidated group of chocolate scrapings in the foil now resembles sedimentary rock.
Make "metamorphic" chocolate next:
1. Fill some aluminum foil or a cupcake holder with a small pile of your sedimentary chocolate, possibly some of your original unused scrapings, and a few small chunks from your initial blocks.
2. Float this mixture in water that is moderately heated.
3. Keep an eye on the foil and chocolate as they begin to melt when the heat from the water is transferred to them.
4. When the chocolate feels soft to the touch, remove the foil (for safety, use the plastic knife, not the fingers).
5. Allow the chocolate to cool. The chocolate has now chilled and only half melted, resembling metamorphic rock.
Make "igneous" chocolate next:
1. Fill your aluminum foil or cupcake holder with a tiny mound of sedimentary and metamorphic chocolate and a few pieces from the initial blocks.
2. Float this mixture in extremely hot water.
3. Observe how the heat from the water is transferred to the foil and melting chocolate. The chocolate should be allowed to melt until smooth liquid forms.
4. Carefully remove the melted chocolate from the aluminum container and let it cool. Now that your chocolate has melted and cooled, it resembles volcanic rock.

Under what circumstances might the plates of the earth stop moving?
For the earths core to cool enough for convection to stop, then the plates would have no convection current to move them.
What do you mean by convection?Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity.
Convection occurs on a large scale in atmospheres, oceans, planetary mantles, and it provides the mechanism of heat transfer for a large fraction of the outermost interiors of our sun and all stars.
Fluid movement during convection may be invisibly slow, or it may be obvious and rapid, as in a hurricane.

Scientists believe the smaller prokaryote in this example evolved into which organelle? Think about it! HINT: ATP and "Heterotrophic"

The endosymbiotic theory states that chloroplasts and mitochondria used to be free-linving bacteria that got phagocyted by another cell. The correct option is 2. Mitochondria.
What does the endosymbiotic theory state?
The endosymbiotic theory proposes that mitochondria and chloroplasts were once free-living bacteria that were phagocytized by another cell but not digested.
These bacteria got to adapt to their host, and both cells became interdependent.
Both organelles have many similarities with other free-living bacteria.
Chloroplasts probably derivate from cyanobacteria because both cells absorb sunlight, produce ATP, and organic molecules. Mitochondria derivate from rickettsias because they produce ATP in the same way by using the Krebs Cycle and Oxidative Phosphorylation.From the phagocytosis moment, these two cells became so dependant on each other, they could not survive without the other one.

Blood flows in layers within the lumen of blood vessels, with the layers in the middle of the lumen flowing fastest. this is known as laminar flow.
What is Laminar flow ?The majority of the circulatory system typically operates with laminar flow. It is characterised by parallel motion of concentric layers of blood along a blood vessel's length. The middle of the vessel has the highest velocity (Vmax).
Laminar flow is when the flow is fastest in the centre of the blood vessel and slowest along the wall of the vessel, where there is greater friction (where there is less friction).Blood flow in the body is typically laminar. Laminar flow can, however, be disturbed and turn turbulent under situations of high flow, particularly in the ascending aorta.

We often do not think of gas in terms of having mass. The atmosphere is something we live in and breathe. In this experiment, we will investigate whether gas does truly have mass.
Hypothesis: If gas does indeed have mass, then different volumes of it will have a different mass. This could be demonstrated by using a simple balance and comparing the two different volumes, captured by means of balloons.
Materials needed:
two balloons of the same size
meter stick
string
paper clips
Procedure:
1. Suspend the meter stick from the middle in such a way as to be able to move the string to balance. See the diagram below.
2. Attach each balloon to either end of the meter stick, making the apparatus balance.
3. Blow up each balloon to different volumes, thus measuring out different volumes of gas.
4. Attach the balloons as shown in the diagram below using the paper clips. Be careful to attach the balloons in the same place as where the apparatus balanced.
5. Answer the following questions in the writing space provided in this assignment.
Did the suspended balloons balance?
If they did not, which balloon tipped the scale down?
Did your results validate the hypothesis?
Give an explanation for your results, including a discussion of how the data collected either validated, or disproved the hypothesis.
The suspended balloons did not balance. The bigger balloon tipped the scale down. And yes, it validated the hypothesis that gas does have mass, as the bigger balloon weighed down the scale.
Gases have mass. Gas particle gaps are completely empty. Chemical reactions can produce gases as a byproduct. Under some circumstances, bonding between gas atoms is possible.
Loosely packed molecules can be found in gases. Gases have weight because the molecules that make them up have mass. Because of this, a balloon with air inside weighs more than one with none.
After combining the vinegar and baking soda, one of the paper bags will be "poured" with gas from the pitcher, which will cause the scale to tip toward that end even though nothing actually was poured into the bag. It is demonstrated by this that gas has mass and is heavier than oxygen.
