(2) Scientific investigation and reasoning. The student uses scientific inquiry methods during laboratory and field investigations. (3) Scientific investigation and reasoning. The student uses critical thinking, scientific reasoning, and problem solving to make informed decisions and knows the contributions of relevant scientists. (4) Scientific investigation and reasoning. The student knows how to use a variety of tools and safety equipment to conduct science inquiry. http://ritter.tea.state.tx.us/rules/tac/chapter112/ch112b.html
(5) Matter and energy. The student knows the differences between elements and compounds. (6) Matter and energy. The student knows matter has physical properties that can be used for classification. (7) Matter and energy. The student knows that some of Earth's energy resources are available on a nearly perpetual basis, while others can be renewed over a relatively short period of time. Some energy resources, once depleted, are essentially nonrenewable.
(5) Matter and energy. The student knows that interactions occur between matter and energy. (6) Matter and energy. The student knows that matter has physical and chemical properties and can undergo physical and chemical changes.
(5) Matter and energy. The student knows that matter is composed of atoms and has chemical and physical properties.
(8) Force, motion, and energy. The student knows force and motion are related to potential and kinetic energy. (9) Force, motion, and energy. The student knows that the Law of Conservation of Energy states that energy can neither be created nor destroyed, it just changes form.
(7) Force, motion, and energy. The student knows that there is a relationship among force, motion, and energy.
(6) Force, motion, and energy. The student knows that there is a relationship between force, motion, and energy.

(5) Matter and energy. The student knows that matter is composed of atoms and has chemical and physical properties. The student is expected to: (E) investigate how evidence of chemical reactions indicate that new substances with different properties are formed
Part 1: Sodium Polyacrylate 5 observations when dry 5 observations after water is added Part 2: Liquids 5 observations about each liquid Combine and stir 5 observations about product
Was the result of part 1 physical or chemical change? Support your answer with evidence. Was the result of part 2 physical or chemical change? Support your answer with evidence. Suggest a possible use for each of these substances.
Claim: make you claim; was the result physical or chemical change? Evidence: describe the evidence that supports your claim. Reasoning: based on the evidence, what is your reasoning that lead to your claim?
Process Skills Used? Content Alignment (TEKS)? What would you change?
(8) Force, motion, and energy. The student knows force and motion are related to potential and kinetic energy. The student is expected to: (A) compare and contrast potential and kinetic energy
Big Question: Do all balls have the same amount of potential energy? Design an investigation that will allow you to collect data to answer this question. Do your investigation and record your results. Write a C-E-R summary or design a follow-up investigation
Predict: what do think will happen? Explain: explain the reasoning behind your prediction Observe: describe what you observed

(7) Force, motion, and energy. The student knows that there is a relationship among force, motion, and energy. The student is expected to: (A) contrast situations where work is done with different amounts of force to situations where no work is done such as moving a box with a ramp and without a ramp, or standing still

(6) Force, motion, and energy. The student knows that there is a relationship between force, motion, and energy. The student is expected to: (C) investigate and describe applications of Newton's law of inertia, law of force and acceleration, and law of action-reaction such as in vehicle restraints, sports activities, amusement park rides, Earth's tectonic activities, and rocket launches
