Learners discover that multiplying transformation matrices produces a composition of transformations. Using software, they map the transformations and relate their findings to the matrices. 

Students find the percent composition of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a sample of potassium chlorate to decompose it into potassium chloride and oxygen. They weight their initial...

Analyze functions by decomposing complex functions and composing simple functions. Through a detailed lesson plan, pupils learn the vocabulary and notation related to the composition of functions. Practice includes both evaluating and...

Young mathematicians solve composition of functions. They add, subtract, multiply and divide functions and then identify the domain and range of each function. An embedded animation shows three different applications of function...

Students discover their body weight and composition. In this health instructional activity, students use a body mass indicator to identify their percentage of body fat. Students develop an exercise plan and record progress throughout a...

Can you follow a composition of transformations, or better yet construct them? Young mathematicians analyze the composition of dilations, examining both the scale factor and centers of dilations. They discover relationships for both...

Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...

Students solve two functions at once. In this algebra lesson, students add, subtract, multiply and divide composition functions. They use the correct notation and substitution to get their answer.

Use an activity to illustrate the different forms of a quadratic function. Here, the task asks learners to use composition of given functions to build an explicit function. The process emphasizes the impact of the order of...

Scholars take transformations from the second to the third dimension as they extend their thinking of transformations to include three-dimensional figures. They explore how to use matrices to represent compositions of...

High schoolers investigate the structure of the atom and its composition. For this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate...

It's time to roll up those sleeves and get a little dirty in the second lesson of this series on the science of food. Investigate where plants and animals get the minerals they need to live in this two-part exploration of soil. First,...

Beyond the phases of the moon, this comprehensive lesson plan covers geologic history and geology. Amateur astronauts examine photos of the lunar landscape, experiment with the creation of craters, and delve into information about the...

Students solve composition of functions. In this algebra lesson, students find the sum, difference and product of functions. They find the inverse of a function.

Students solve problems using the composition of functions. In this algebra lesson, students analyze the graph of a quadratic equation for its vertex and intercepts. they find the inverse of the function using addition, subtraction,...

Students perform soil tests for pH, nitrogen, phosphorus, potassium, composition and water percolation rate and assess the conditions in the schoolyard.

Students are introduces to soil profile classification. They remember that classification of soils is an important aspect of studying soils as it aids in predicting how soils react to weathering, transport nutrients or pollution. ...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

Young scholars investigate the chemical composition of pennies dated 1983 or later. In this chemical composition of American coins lesson plan, students scratch the surface of the penny to expose the zinc core. They put the penny in...

Fourth graders review by sorting and classifying minerals. They describe the composition of a mineral and use rules to classify that mineral. They complete a mineral scratch test and place the results in a table in the second activity.

Fourth graders examine soil to find its contents, and how much water and air they can measure.  In this soil composition lesson, 4th graders perform three experiments and record their results.  In one experiment they examine...

Fourth graders create dances through a randomly generated process (such as throwing a dice) and perform their dances for the class. Class work is based on Merce Cunningham's "Chance Dance" and includes walking, skipping hopping, and...

Students investigate how soil composition affects plant growth. In small groups, they plant various seeds in different soil mixtures, record plant and seed growth, and analyze the results.

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...
