Conservation of Momentum
This resource was created to support TEKS IPC(4)(E).
Equipment for Biology
Given investigation scenarios, students will determine the equipment that best fits the procedure.
Homeostasis—Succession
Given scenarios, illustrations, or descriptions, the student will identify the process of ecological succession and the impact that succession has on populations and species diversity.
Cell Specialization and Differentiation
Given examples, descriptions, and illustrations, students will be able to describe the role of DNA, RNA, and environmental factors in cell differentiation.
Valence Shell Electron Pair Repulsion
Given illustrations or descriptions, students will predict the shape of molecules based upon the extent of the electron pair electrostatic repulsion.
Chemical Bonding: Metallic Bonds
Given scenarios or diagrams, students will describe the nature of metallic bonding and explain properties such as thermal and electrical conductivity, malleability, and ductility of metals.
Nomenclature: Covalent Compounds
Given descriptions, diagrams, or scenarios, students will write and name the chemical formulas of binary covalent compounds.
Ionic Bonds: Electron Dot Formulas
Given descriptions, diagrams, scenarios, or chemical symbols, students will model ionic bonds using electron dot formulas.
Moles and Molar Mass
Given descriptions or chemical formula of a substance, students will use the concept of a mole to relate atomic mass to molar mass.
Types of Solutions: Saturated, Supersaturated, or Unsaturated
Given scenarios, graphs, diagrams, or illustrations, the student will determine the type of solution such as saturated, supersaturated, or unsaturated.
Producing Plump Produce
In collaborative groups, the students investigate the transport of water within potato cells placed in various tonicity solutions.
Teacher explains the task to the students
Energy Transfer in an Ecosystem
All matter contains energy. Energy can be transferred from one object to another. Energy transformation can occur through the conversion of energy from one form to another. Energy is never created nor destroyed; it is always transferred and/or transformed. Students will demonstrate how energy is transformed and transferred in an ecosystem. To do this, students will create energy pyramids by stacking cups that represent organisms and available amounts of energy. Students will graph and analyze the data.
Students working on the task
Plant, Parts, and Function
Students use prior knowledge of body systems as they make connections to systems in plants. Students learn that some plant systems have similar functions as the respective animal systems. The lesson highlights the following systems in plants: root system, shoot system, vascular system, and reproductive system.
3.04 Bar Charts
In this video, students learn about bar charts as well as how to read and construct one.
3.05 Comparing Distributions
In this video, students will compare bar charts, pie charts, and frequency tables to see differences in results.
2.01 Sample Surveys
In this video, students are introduced to surveys and the idea that substantial size and random selection are necessary for good results.
2.02 Sources of Bias in Sampling and Surveys
In this video, students learn about the bias that occurs in sampling.
2.03 Sampling Methods, Part 1
In this video, students learn various ways of obtaining sample data.
2.04 Sampling Methods, Part 2
In this video, students continue with practice problems about different sampling techniques.
2.05 Experiments vs. Observational Studies
In this video, students explore the differences between experiments and observational studies.
