Types of Science Investigations
Students will distinguish between descriptive, comparative, and experimental investigations.
Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.
This resource provides flexible alternate or additional learning activities for students learning about the gravitational attraction between objects of different masses at different distances. IPC TEKS (4)(F)
Elements and Compounds
This resource provides flexible alternative or additional learning opportunities for students to differentiate between elements and compounds on the most basic level, Science TEKS (6)(5)(C).
A Tier 1 earth science instructional resource for kindergarten.
Forces at Work
A Tier 1 force and motion instructional resource for grade 3
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
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.
