Students differentiate between exponential and logarithmic functions. In this algebra lesson, students use logarithmic properties to solve equations. They identify growth and decay of graphs.

Students investigate the growth and decay of an exponential function. In this algebra lesson, students apply properties of exponent solve problems. They identify any patterns they see in the graphs.

Students plot on a coordinate plane. In this algebra lesson, students identify points on a coordinate plane and graph lines given coordinate pairs. They create a model as they study bald eagles and their growth and decay.

Students explain how radioactive decay occurs. In this physical science lesson, students simulate radioactive half-life through an experiment. They graph their data and share their results in class.

Students examine the following concepts: If water supplies contain materials which rot or decompose, oxygen is used. Decay and decomposition require vast supplies of oxygen. The use of oxygen for decay of wastes may be a life or death...

Students explore, examine and study a module that focuses on the science of the oral environment and major scientific concepts relating to oral health. They investigate the process of tooth decay by interacting with stories and games...

Students sequence the steps in a normal day that can lead to tooth decay and describe how to maintain a healthy mouth.

Pupils recognize that plants and soils have a close relationship. They view a photo essay on the common practice and natural process of composting. Afterwards, they observe the process of plant decay over the course of several days.

Students practice graphing relationships between variables by studying topics such as exponential growth and decay. They conduct a series of numerical experiments using a computer model and a variety of physical experiments using mold,...

Young scholars find maps of the region to show rock formations and soil types and use GIS to compare radon levels. They describe three types of radioactive decay, interpret graphs, and follow steps to develop a nuclear bomb or energy.

Students create a scale model of the different eras, periods, and epochs of Earth's 4.6 billion year history. In addition to different time periods, other major events will also be added to the model from fabricated radioactive decay...

In this geological history activity, high schoolers define 17 terms associated with index fossils, nuclear decay, and radioactive decay.

Students begin the lesson with a review of the elements of poetry. Individually, they read a variety of poems and literature one white and one black author focusing on decay, sterility and alienation. They identify these images within...

In this word search worksheet, students locate 17 words related to earthworms. Words include decayed, present, similar, waste, enemies, and insects.

In this teeth worksheet, students have a partner examine their teeth, then on a provided diagram, color teeth that are present the color blue, missing teeth red, and an X to show fillings or decay. 

Seventh graders study elapsed time, radioactive decay and half-life.  In this time machine lesson students complete several activities and view a presentation. 

Secondary learners investigate exponential functions in a real-world scenario. They collect data on the temperature of a cooling baked potato, enter the data into lists, and graph the data using a scatter plot before finding an...

An inventive lesson plan shows learners how to collect, organize, and present mathematical data. They access websites which lead them through a variety of ways to engage in data collection. They get to design and create graphs, and...

Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...

Recycling is the focus in the sixth of a nine-lesson series devoted to forest ecosystems. Class members read an article about the responsible use of natural resources and ways to reduce land fill.

If mathematicians know the secret to compound interest, why aren't more of them rich? Young mathematicians explore compound interest with exponential functions in the twenty-seventh installment of a 35-part module. They calculate future...

These aren't models made of clay. Young mathematicians model given population data using exponential functions. They consider different models and choose the best one.

Chemists use the destructive distillation technique to produce three derivatives from a sample of bituminous coal. You will find background information, a materials list, procedures, and sample follow-up questions that you can use in...

How do people get sick? Youngsters explore the world of germs and microbes with a lab sheet and science investigation. After identifying the unhygenic practices in a picture of a kitchen, fifth graders conduct an experiment with bread...
