When you are relaxing on an air mattress in a pool and someone does a cannonball dive off the diving board, you suddenly find yourself bobbing up and down.. This . powerpoint. will show you the basics of dark matter and dark energy . Their place in the universe . By Jordan . Ilori. . DARK MATTER. Dark matter is a type of matter hypothesized in astronomy and cosmology to account for a large part of the mass that appears to be missing from the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level. Instead, the existence and properties of dark matter are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. According to the Planck mission team, and based on the standard model of cosmology, the total mass–energy of the known universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Thus, dark matter is estimated to constitute 84.5% of the total matter in the universe and 26.8% of the total content of the universe.. Science, Matter, Energy, and Systems. Scientists use a variety of methods to learn about how the physical world works.. The methods fall into a general process.. Science is used to search for order in nature.. &. Matter and Energy. .

It's what everything that occupies space and has mass is made of And everything like that is made out of chemical elements There are 92 naturally occurring chemical elements, and a number of synthetic ones Honors Chemistry Matter and Energy MATTER is anything that has mass and volume. Do you know ALL the states of matter? Kinetic Molecular Theory of Matter Assumptions: All matter consists of particles, such as, atoms, molecules, formula units. Matter Chapter 2.1 Sept 22, 2015 Objective: Distinguish between elements and compounds and categorize materials as pure substances or mixtures Lab safety: do not touch or taste anything without permission that is not yours Mono Lake.
