Evidence for Evolution
Learners analyze and evaluate how evidence of common ancestry among groups is provided by the fossil record, biogeography, and homologies, including anatomical, molecular, and developmental.
Equipment for Biology
Given investigation scenarios, students will determine the equipment that best fits the procedure.
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.
Heat to Go
This resource provides alternative or additional tier-one learning options for students learning about heat transfer, Chemistry TEKS (11)(B).
Celsius 4-1-1: All About Thermal Energy
This resource supports Chemistry TEKS (11)(A).
Kinetic Molecular Theory
This resources allows students to explore the postulates of the Kinetic Molecular Theory in order to better understand why gas particles behave the way that they do.
It's All About Cell Theory
This resource provides flexible alternate or additional learning opportunities for students to recognize the development and components of the cell theory, TEKS (7)(12)(F).
Covalent Bonding: Electron Dot Diagrams
Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).
6 Chapter 6: Stoichiometry
In this chapter, students are introduced to the mole, mass relationships, and stoichiometric calculations with balanced equations.
2 Chapter 10: Light
In this chapter, we discuss visible light and other forms of electromagnetic radiation.
8 Chapter 3: Measurements
In this chapter, we strengthen math skills necessary for chemistry problems and discuss the SI units of measurement. Additionally, we convert between units of measurement and discuss interpreting data from graphs and tables.
3 Chapter 14: Nuclear Chemistry
In this chapter, we discuss nuclear reactions that occur in unstable nuclides.
8 Chapter 11: Electron Configuration and Periodic Trends
In this chapter, we discuss determining electron configurations and periodic trends.
3 Chapter 4: Science and Me
In this chapter, we will discuss how chemistry affects our everyday lives and how you can find careers in chemistry.
6 Chapter 8: Gases
In this chapter, we discuss the properties of gas particles and the laws that govern their behavior.
