45-45-90 Triangles

To learn the pattern of the side lengths of a 45-45-90 triangle, students complete a gallery walk, a card sort activity starting with using the Pythagorean theorem, and activity to locate if there is an error in a presented problem and if so to identify what the error is.

###
Types of Motion

Students will distinguish between and/or interpret the types of motion.

###
Demonstration and Analysis of Dihybrid Crosses

The students will review related vocabulary, watch the teacher model a dihybrid cross, and then perform a dihybrid cross and answer questions about the outcomes with a partner.

###
Predict Monohybrid Crosses

Biology Kid2Kid videos present biology concepts taught to a student by a student. This resource contains videos that explain monohybrid crosses in both English and Spanish.

###
Cell Homeostasis: Osmosis

The focus of this resource is cell homeostasis and, more specifically, osmosis. Students investigate the concept through a virtual lab, recording and analyzing data, creating sketches to represent vocabulary, and discovering the role of aquaporins in water transport through the cell membrane.

###
Newton's Three Laws of Motion

This resource provides alternate or additional learning opportunities for students learning the three Newton's Laws of Motion. It includes a collection of interactive materilas, videos, and other digital media. Physics TEKS, (4)(D)

###
Using Logical Reasoning to Prove Conjectures about Circles

Given conjectures about circles, the student will use deductive reasoning and counterexamples to prove or disprove the conjectures.

###
Drawing Conclusions about Three-Dimensional Figures from Nets

Given a net for a three-dimensional figure, the student will make conjectures and draw conclusions about the three-dimensional figure formed by the given net.

###
Generalizing Geometric Properties of Ratios in Similar Figures

Students will investigate patterns to make conjectures about geometric relationships and apply the definition of similarity, in terms of a dilation, to identify similar figures and their proportional sides and congruent corresponding angles.

###
Determining Area: Sectors of Circles

Students will use proportional reasoning to develop formulas to determine the area of sectors of circles. Students will then solve problems involving the area of sectors of circles.

###
Making Conjectures About Circles and Segments

Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties and relationships among the resulting segments.

###
Determining Area: Regular Polygons and Circles

The student will apply the formula for the area of regular polygons to solve problems.

###
Making Conjectures About Circles and Angles

Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties of and relationships among the resulting angles.

###
Solving Problems With Similar Figures

Given problem situations involving similar figures, the student will use ratios to solve the problems.

###
Cell Comparisons

Learners compare a variety of prokaryotes and eukaryotes to determine similarities and differences among and between them.

###
Monohybrid and Dihybrid Crosses

Learners calculate the probability of genotypic inheritance and phenotypic expression using mono- and dihybrid crosses.

###
Mechanisms of Evolution Beyond Natural Selection

Learners analyze and evaluate the effects of other evolutionary mechanisms.

###
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.

###
Protein Synthesis

The learner explores the structure and function of the nucleic acids and enzymes important to the process of synthesizing proteins.

###
Electric and Magnetic Forces

Given diagrams, illustrations, or descriptions, students will identify examples of electric and magnetic forces.
