methods. be sure to include your claim, evidence, and reason for connecting the evidence to the claim.
• represent your scientific explanation using a model (physical or diagram). attach an image or a video
demonstrating your model.
explain your scientific explanation using an oral communication method, such as a video of yourself, a
conversation with another student, a skit, or an audio file. attach your video or audio file.
• present your scientific explanation in a creative written form using studio,
• write your scientific explanation in the space below.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
