Students explain the content, purpose, and impact of the Tax Reform Acts of 1969 and 1986.

Introduce the inverse matrix method to solve systems of linear equations both algebraically and graphically. Using given data, your class checks their answers with graphing calculators. Handouts are included in this well-thought out lesson.

Analyze functions by their shape and equation and identify decay and growth based on the equation given. Learners graph their exponential functions and differentiate it using the logarithmic versus the exponential function.

Learners discuss the relationship between and the equivalent forms of rational numbers. They will convert numbers from decimals to fractions, understanding they are equivalent, but just different forms.

Learners will have fun creating a parachute to collect data with. They will construct the parachute in small groups, measure the materials, and create an observation sheet. Then they drop the parachute and make predictions about how long...

Learners use the on-line affine recurrence plotter to graph equations. They work on-line to create graphs of trout in a trout pond and savings account balances when interest is compounded over time. Links to the four one-day lessons are...

Explore communication in this interview skills lesson. English learners identify the techniques native English speakers use when speaking directly to a potential employer. They read handouts detailing seven steps to improve an interview...

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes. This...

Students identify the four basic natural resources. They distinguish bettween renewable and non-renewable resources. Pupils recognize that all natural resources are needed by living plants and animals. Students list consequences for...

Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...

Learners identify the stages of the water cycle. They listen to the book "Magic School Bus: Wet All Over," examine the Build Your Own Water Cycle website, predict and measure the amount of water in a jar for a week, and read a short play...

Help writers recognize how word order affects meaning, discover new words, and confirm or check meaning writing. They will explore how punctuation helps a reader understand what is written and the connections between punctuation,...

Students explore the many different food chains. They participate in a game in which the class is divided into the different parts of the food chain.

Students explore how food is made and what are healthy and unhealthy eating habits. They participate in activities to further show them foods nutritional value.

Consider complex numbers, roots, and quadratic equations. Use the discriminate as a way to determine the nature of a quadratic's roots. Then discuss the similarities and differences between quadratics with two, one, or no real roots....

Students discuss the characteristics of the biosphere, with a focus on the Tibetan Plateau. They participate in a question and answer period discussing biomes and climate patterns. They compare and contrast different ecosystems.

Students identify the biomes of the Earth and their characteristics. They discuss their favorite seasons and the weather. They share their favorites with the class.

Students observe the sky and weather to gather data. They conduct experiments to answer questions about the sky and weather phenomena. They measure, analyze and present data. They create sky windows by gluing sky colored paint chips...

Students discuss the different types of climate zones found throughout the world. They participate in activities which relate to real events. They make observations and the consequences of their actions on the environment.

Students explore the different arrangement of air molecules in high and low air pressure masses. They compare the temperature of high and low pressure masses and discover how a barometer works.

Young scholars investigate the relationship of the steps in the water cycle, and create a simulation of the water cycle in a jar.
