Natural human interest in patterns and algebraic study of function notation are linked in this introductory unit on the properties of sequences. Once presented with a pattern or situation, the class works through how to justify...

The language and features of functions get careful treatment in a complex but doable lesson. Learners get a lot of practice really figuring out what a graph means in context, and also identifying key features of graphs. Key ideas...

The coordinate plane links key geometry and algebra concepts in this approachable but rigorous unit. The class starts by developing the distance formula from the Pythagorean Theorem, then moves to applications of slope. Activities...

Sequences and series are traditionally thought of as topics for the pre-calculus or calculus class, when learners are figuring out how to develop limits. But this unit uses patterns and slopes of linear functions in unique ways...

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

Statistics is made approachable, and dare we say fun, in this activity on using box-and-whisker plots to analyze and compare data sets. Specific emphasis is placed on interpretations and explanations while graphing, and in using the...

This first of twelve algebra 2 resources provides a broad review of many algebra 1 concepts through a number of separable lessons and labs. Starting with the real number system and its subsystems, the sections quickly but thoroughly...

A fabulous set of examples and problems that introduce basic trigonometry concepts, this packet is set apart by the care it takes to integrate both radians and degrees into the material. After defining radians, the author demonstrates...

You have just got to do it! Reinforce math skills with an exercise on converting fractions into percentages.

Here is a resource with a descriptive approach to explaining the scientific method. It's simple, but effective for both introduction and reinforcement of this concept. 

Young scientists compile everything they have learned into a report in the fifth and final lesson in a unit on the visible light spectrum. Access to photos from observatories, telescopes, and satellites allows learners to compare...

Taxonomy is the study of organisms and how you phylum. Three biology activities are included, helping scholars understand four of the six kingdoms, specifically Protista, Plantae, Fungi, and Animalia. Scholars observe and classify...

Four out of five teenagers experiment with science by accident. This unit teaches the five parts of the scientific method through examples, guided practice, independent practice, and then through a hands-on experiment. Each step is...

The Bill of Rights is a foundational document of American democracy, much like the Nuremberg Laws were a foundational document of the Reichstag of Nazi Germany. But that's where their similarities end. Engage high schoolers in a...

The poems of Walt Whitman and Emily Dickinson are the focus of a unit that asks readers to consider how an artist's life and changes in society influences his or her work. After careful study of Whitman's and Dickinson's perspectives on...

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

It's pretty common to determine the dissociation constant for an acid or a base ... but, what about a protein? Challenge your class with a virtual lab designed to further develop their acid-base chemistry skills. Individuals determine...

Looking for an easy way to give your class experience with acid-base chemistry outside the lab? Try a detailed interactive that puts them in total control! Young chemists determine the dissociation constant and concentration of an...
