Young scholars investigate circles and compound locus. In this geometry lesson, students identify the distance from a point to a line. They use Cabri software to create lines and circles.

Students define the five rules of loci. In this geometry lesson, students identify the locus of points that creates a circle. They calculate the distance from a fixed line and point.

Students differentiate between ellipse and hyperbola. In this algebra lesson, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Groups plan their escape carefully. Three three-tiered puzzles help a story character escape their situation, each involving integer sequences, transformations, and geometric constructions. The teacher resource includes...

Twelfth graders review for their analytic geometry test. In this calculus lesson, 12th graders review equations of graphs, relationship between graphs and equations, and transformation of graphs. After the review students are given...

Students study Mendelian genetic terms, locate and name loci on chromosomes, karyotype construction, inheritance patterns through families.

Explore the properties of parabolas in this lesson. Construct a parabola given a focus and a directrix on the Ti-Nspire. Write equations of parabolas in vertex form and determine the a value of a parabola given a focus and directrix.

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Put together the pieces and model a parabola. Learners work through several examples to develop an understanding of a parabola graphically and algebraically. 

Learners slice cones and identify the different conics formed. They then derive the formula to solve problems involving cones. Pull out the TI calculators to visualize the slicing and the different parts and properties created.

Students investigate genetics and evolution of species. They simulate the breeding of birds using origami birds. In addition, using dice they introduce genetic variation into the species.

Tenth graders discuss their physical features, and why they look the way they do. They listen as the teacher discusses DNA, alleles, and dominant or recessive genes. Students perform an experiment with different colored markers...

Students participate in an activity where they flip coins to determine which allele they pass on to the F1 generation and draw the resulting child's face. They identify several inheritance patterns including dominant, recessive,...

Students collect DNA from cheek cells. They compare and contrast the processes of DNA replication and PCR. They discuss how this information can be used to determine guilt at crime scenes.

Students explore the mode of inheritance of chromosomes. Given a scenario, students use the Human Genome sheet to determine inherited chromosomes. They illustrate the difference between genotype and phenotype. Students develop a model...

Students gain a feeling for the significance of the Hardy-Weinberg Equilibrium without using algebra but participating in an interactice game.

Students are introduced to the construction geometrically of parabolas. Using a software program, they identify lines, segments and midpoints. They label the parabolas properties and characteristics and use a formula to determine the...

Eighth graders create a database of animals and birds in the area in which they live. They use molded prints to make a cast of an imprint from a specific animal. They identify and research animals and prepare an outline for an oral...

Students slve a case of unclear heredity using three lines of evidence and knowledge gained from the activity in this biology activity about Mendelian inheritance. The activity includes handouts and a question sheet for final, individual...

Sixth graders discover the ways archaeologists examine artifacts and where they are found. After being introduced to new vocabulary, they use artifacts from their own lives and discover what could be told about their life from them. ...
