There are four fundamental theorems of mathematics: arithmetic, algebra, calculus, and linear algebra listed here. Each one is described on this poster or handout. The challenge for a student of math is to figure out why they are...

Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

In this ecology community status worksheet, students research their state's ecosystem, make a chart of the biodiversity, analyze the chart and identify issues with wetland species.  This page has several links to helpful web resources.

Students differentiate the types of cryptosystems and use them to communicate privately. In this algebra lesson plan, students use substitution and transposition to identify the cryptographs. They send and receive cryptograms as...

In this food web relationships instructional activity, students click on the links to learn about the food web relationships in the wetlands and answer short answer questions about it. Students complete 8 questions total.

Students develop an understanding of pi and the relationship between the diameter, radius and circumference. After a lecture/demo, students use construction paper and a compass to solve problems using diameter, radius and circumference.

Eleventh graders define various types of linear systems and three types of solutions. For this linear system and echelon forms lesson, 11th graders solve a linear system using elementary row operations. Students also describe the set of...

Eleventh graders study homogeneous linear systems. In this linear system of equations lesson, 11th graders write linear system solutions in parametric vector form. Students also identify the connection between linear independence and...

Students define vocabulary related to vectors and investigate vector problems. In this math lesson, students define basis and explore plotting vectors in correlation to their basis. Plotting polynomials facilitates student understanding.

Third graders explore the elements of a story using fairy tales from all over the world. They compare and contrast story elements, key ideas and concepts found in a variety of texts from around the world.
