Theories
Given laboratory investigation scenarios, students will distinguish between scientific hypotheses and scientific theories.
Moon Phases
Tier I resource for instruction on the lunar phases.
TEA Science Safety Training for Elementary School
Increase your awareness of science safety in the elementary classroom. Teachers will better understand their duty to instruct, supervise, and maintain a safe science classroom. This resource does not take the place of campus- or district-level science safety training.
Introduction to TEA Science Safety Training for Middle School
This section is the introductory text for the course.
Science Academies for Grades 5–8, Part 2 for Trainers
This resource contains the files needed for trainers responsible for training science teachers in grades 5–8 across Texas.
Science Academies for Grades 5–8, Part 2 for Participants
This resource is available to participants of the Science Academies for Grades 5–8, Part 2. The purpose of the resource is to provide participants with the training materials and documents associated with the training.
3.01 Distance and Displacement
In this video, we explore the difference between distance traveled (an example of a scalar) and displacement (an example of a vector), and we review some basic vector math.
3.02 Average Speed and Average Velocity
In this video, we explore the difference between speed and velocity, and their relationship to distance and displacement.
3.03 Kinematic Equations in One Dimension
In this video, we introduce the three primary kinematics equations and apply them to one-dimensional problems. The term "acceleration" is also introduced.
3.04 Kinematic Equations Graphical Analysis
In this video, we analyze hypothetical experiments by graphing position, velocity, and acceleration versus time, qualitatively.
3.05 Kinematic Equations in Two Dimensions
In this video, we apply the three primary kinematic equations to projectile motion problems.
3.06 Relative Motion
In this video, the inherent (classical) relativity of velocity measurements is explored, qualitatively and quantitatively, in both one and two dimensions.
10.01 Wave Nature of Light
In this video, we will study the wave-like properties of light.
10.02 Particle Nature of Light
In this video, we will study the particle-like properties of light.
6.01 The Mole
In this video, we will study the mole and its applications in chemical calculations.
6.02 Percent Composition
In this video, we will calculate percent composition or mass percent and various applications.
6.03 Empirical and Molecular Formulas
In this video, we will learn the difference between an empirical and molecular formula and how to find them.
6.04 Balancing Equations
In this video, we will learn how to balance chemical equations using the law of conservation of matter.
6.05 Stoichiometry with Balanced Equations
In this video, we will apply stoichiometric concepts to balanced equations in order to determine mass relationships within reactions.
6.06 Limiting Reactants and Percent Yield
In this video, we will investigate limiting reactants and how they affect chemical reactions
