The periodic table has so much more to it than meets the uninformed eye. An inquiry-based lesson leads learners through the history of the discovery of several transuranium elements. They then use informational resources to build a...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, young scholars build molecules based on the chemical formulas of common...

Show learners the power of mathematics as they model real-life designs. Pupils graph a periodic function by comparing the degree of rotation to the height of a ferris wheel. 

Given a value of one trigonometric function, it is easy to determine others. Learners use the periodicity of trigonometric functions to develop properties. After studying the graphs of sine, cosine, and tangent, the lesson connects...

Scholars use data to analyze and determine which sets of information need to be counted. They create a model to explain differences among chemical elements using graphs to prove concept mastery.

Have young mathematicians create new identities! They explore the even/odd, cofunction, and periodicity identities through an analysis of tables and graph. Next, learners discover the relationships while strengthening their...

Help learners discover the unique characteristics of the tangent function. Working in teams, pupils create tables of values for different intervals of the tangent function. Through teamwork, they discover the periodicity, frequency, and...

What does math have to do with the behavior of the earth and sun? Learn how the movement of celestial bodies has influenced the development of trigonometry. Scholars connects the details in mathematics to their...

Knowing the addition formulas allows for the calculations of double and half formulas. The fourth installment of 16 has the class use the addition formula to develop the double angle trigonometric formulas. Using the double formula,...

The key is ... After a day of instruction on key features of graphs, groups create a poster and presentation on the key features of their given function graph. The resource provides an extension activity of "telephone" using...

Six middle school chemistry lessons about the periodic table and bonding complete with handouts and animations.

Students explore the periodic table and learn the basic information given for elements: the name, symbol, atomic number, and atomic mass for each element.

Students interpret the information given in the periodic table to describe the arrangement of electrons on the energy levels around an atom.

Explore the elements found in the Periodic Table of Elements and what role some of them play in the universe. Test your knowledge of the elements and the organization of the table by completing a puzzle.

Young scholars use the water-displacement method to find the volume of different rods that all have the same mass.

Students are presented with a table that shows the populations of foxes and rabbits in a national park over a 12-month period. This is the second Foxes and Rabbits task. In this problem, students must find trigonometric functions that...
