Each unit is made up of a series of investigations, which are in turn consists of several activities. Driving questions and overviews for each unit are included below. Unit 1: Why do some clothes stick together when they come out of the dryer? Students develop a model of electric interactions to explain electrostatic phenomena. To develop and revise their models, students collect evidence related to how charged objects interact with other objects. They develop a particulate model of materials and a model of atomic structure to start building an understanding of the mechanism of charging objects. Unit 2: How does a small spark trigger a huge explosion? Students further develop their model of electrostatic interactions by incorporating the relationship between electric potential energy and electric forces. In particular, the unit focuses on the electrostatic attractions and energy conversions involved in the formation of molecules chemical reactions.

Lesson 1 — Pretest and Features of Ecosystems students as questioners Activity 1. Activity 1. NGSS Performance Expectations This lesson helps students start thinking about all of the NGSS performance expectations for this unit but does not focus on their mastery on of any of them. Three-dimensional Learning Progression In previous Carbon TIME units, students learned to explain macroscopic processes plant growth, combustion, decay, etc. In this unit, they must connect the macroscopic and atomic molecular scales to matter cycling and energy flow at the larger ecosystem scale. When organisms use organic matter for cellular respiration, ALL the matter goes back into CO2, water, and minerals, while ALL the energy leaves the ecosystem as heat which is ultimately radiated out into space. So, matter cycles and energy flows through ecosystems. Are they connecting scales? Students will need to apply what they learned about transformations of matter and energy in individual organisms to ecosystem-scale processes—to see how matter cycling and energy flow in ecosystems result from the atomic-molecular processes of photosynthesis, biosynthesis, digestion, and cellular respiration.

Matter and Energy Unit Test (TEKS)
The study of energy is performed by physicists. There are a number of different types of energy that include potential energy or stored energy , kinetic energy the motion of objects , thermal energy caused when there is a sharp change in temperature , chemical energy caused when a substance is transformed through a chemical reaction , nuclear energy is energy associated with an atomic reaction , mechanical energy is the sum of potential energy and kinetic energy and electrical or electromagnetic energy changes that are caused by the flow of charged ions or electrons through a current. The energy in matter can cause the matter to change. For example, if you the mass stand still at the street corner waiting for the traffic light to turn red, you have potential energy. The potential energy is the ability to move forward across the street but by standing still, that potential energy is being stored.

The Particle Theory of Matter - Section Quiz
Defining Matter and Density Chemistry is the study of matter and the changes it undergoes Particle nature of matter means that properties of matter depend on the particles that make up matter Matter occupies space volume and has mass. The relationship between mass and volume is referred to as "density". Refer to Table T for the formula used to calculate the density of a substance. Answer: 0. Properties of Matter The definition of substance is key to understanding matter. A substance is matter that has "uniform composition", meaning that wherever the sample of the matter is found, it is made of the same thing.
Piersa, Amanda / Matter and Energy
Gold is a substance because it is only made of gold atoms no matter where it is found in the universe. Pure water, H2O, is a substance since it is made of two hydrogen atoms combined with one oxygen atom no matter where it is found in the universe. The ratio of hydrogen to oxygen will always be 2 to 1. Salt water is not a substance since some samples may have more salt or less in the water, so the composition is not "uniform". The ratio of salt and water can be different and still have "salt water". Know the difference between physical and chemical properties.
Science Fusion Grade 6-8 Module H: Matter & Energy Assessment Guide
A physical property is a characteristic of a substance that does not change the substance into a new substance. For example, properties such as melting point, boiling point, density are physical. The melting point of a substance is the temperature that a substance changes from a solid to a liquid. The change from solid to liquid does not create a new substance, therefore, the melting point is referred to as physical property. Chemical property is how a substance combines with another substance to create a new substance.
CONNEXUS ANSWERS
For example, a property of the metal zinc is that when it is combined with hydrochloric acid, it produces a new substance such as hydrogen gas. In each of these examples, the observed property is not the result of the creation of a new substance. Examples of Chemical Properties Include: 1 a metal reacting or combining with an acid to produce hydrogen gas new substance , iron rusting iron combines with oxygen in the air to produce iron oxide, a new substance , combustion as a result of lighting a match due to the substances in the wood combining with oxygen to produce carbon dioxide, which is part of the visible smoke a new substance Know the difference between physical and chemical changes.
HS-LS1-7: Cellular Respiration and Energy Transfer
Examples of physical changes are phase changes, dissolving a solid substance in a liquid, changing the shape or size of a substance, etc. A chemical change creates a new substance as the composition changes of the original substances. A match burning is a chemical change as the substances of the wood combine with oxygen to create new substances such as the gas CO2. Law of Conservation of Mass states that mass in a chemical or physical change cannot be created or destroyed, it just gets rearranged.
Classwork and Homework Handouts
Classifying Matter All matter can be classified as either as a "Substance" or "Mixture". As discussed above, "Substance" is matter that has a uniform composition. There are two categories of substances: elements and compounds. An element is matter that can only be broken down into one substance. Examples: gold, oxygen, hydrogen, iron See Table S for a list of examples of other elements. A compound is a substance that is made of two or more elements in a fixed ratio. Differentiate between homogenous and heterogeneous mixtures In homogeneous mixtures there is no boundary between the substances.
1.E: Matter and Measurement (Exercises)
It looks like it is smoothly blended together. Example: Salt completely dissolved in water. There is no visible boundary between the salt and water as long as you do not add too much salt. In heterogeneous mixtures there is a visible boundary between the substances. Example would be a mixture of oil and water where a boundary that can be seen. A bowl of salad is a heterogeneous mixture since you can see the individual boundaries of the lettuce, tomatoes, olives, etc. Identify matter as a mixture, compound or element. Energy, Temperature and Heat Energy exists in two forms: 1 kinetic energy and 2 potential energy.

Kinetic energy is the energy of the motion of the particles. Chemical potential energy is a more difficult concept, but it relates to the stored energy that is in a substance based on its composition and the forces that that keep the particles of a substance together. Exothermic: A change that releases heat to the surroundings is referred to as "exothermic". For example, when a match is on fire, the change is releasing heat to the surroundings. Endothermic: A change that absorbs energy from the surroundings is referred to as "endothermic". For example, when you heat water to boil it, the process of boiling is "endothermic" since the change requires that water absorbs heat from the surroingings. Significant Figures, Scientific Notation and Percent Error Scientists indicate the precision of measurements of an instrument by the number of digits reported called "significant figures" Significant figures for a measurement is all the known digits that can be read plus one estimated digit.
Study Guides/ANSWER KEYS
The number of significant figures in a number can be determined using the following rules: a all nonzero digits are significant b zeros between nonzero digits are significant c zeros to the left of the first nonzero digitS are not significant d zeros at the end of a whole number are not significant, unless followed by decimal e all FINAL zeros after a decimal point are significant Examples: a The number could be rewritten in scientific notation as 2. For example: mass of substance A is measured at 6. Since the volume is a less precise measurement, the calcualtion of denisty must be to only 1 decimal place.
