In this algebra worksheet, learners solve rational equations including two application problems. This worksheet contains explanations to aid in understanding. 

You would think that humans make up more mass than ants do on this planet, but think again, and this time by performing calculations. Middle schoolers use scientific notation to compute and compare the estimated total mass of all humans...

Learning about the rainforest can be more fun than you think. The class discusses vocabulary-in-context as they cut cardboard boxes, destined to become part of a rainforest model. Small groups of children color, cut, and construct...

A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food...

Explore the Earth's different ecosystems through four lessons, an assessment, and extension activities. Lessons include informative text and step-by-step instructions to apply knowledge in interactive, and thought provoking ways; such as...

Have scholars show what they know with a 20-page assessment aligned to the California State Standards. The test covers concepts such as large and whole numbers, all four mathematical operations, fractions, decimals, geometric figures,...

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

Carbon, the base for all organic compounds, exists in nature in its purest form as graphite or diamonds. The 25th lesson in a series of 36 teaches pupils the nomenclature of organic compounds. Learners read about how to use the IUPAC...

Sixth in a series of 36, this lesson focuses on gases and their behavior in given situations. Learners review the states of matter and then focus on gases, specifically learning Boyle's, Charles's, Avogadro's Laws, Dalton's, and Graham's...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

A matrix is just a fancy way of making a table. Young scholars explore operations with matrices with the first lessons in the final module of a 10-unit Algebra II series. After adding, subtracting, and multiplying matrices, pupils use...

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Students identify the branches of Indiana's judicial system and determine the differences between the different courts and different types of cases. Students create a flow chart showing how a court case works its way through the legal...

Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

Third graders investigate two mathematic scenarios and determine which is correct. They compare adding columns and places (such as the tens place, hundreds place, and so on) and familiarize themselves with how to add larger numbers.

Science learners apply dimensional analysis to relate quantities in six different problems. They consider the cost of steak, a young man's growth rate, a medicine prescription, fuel efficiency, and more. This worksheet is a great way to...

Fifth and sixth graders subtract 15 mixed fractions with unlike denominators and reduce each one to their simplest form. They write and solve two subtraction problems for each model shown. Pupils find the value of n in four Algebra...

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

Students learn about and identify feelings of happiness, sadness and disappointment. In this feelings lesson, students have a show and tell time about their pets and discuss how it would feel if they lost their pet. Students watch a...

Factor polynomial functions that have two and three terms. Using Algeblocks, your class will create models to show their understanding of these concepts.

Students measure angles using a plane table kit. In this geometry activity, students use trigonometric identities to find the values of the length of a football field.

Build an interest and appreciation for architecture in your young learners with this fun 10-lesson art unit. Engaging children in using their five senses, the class first observes the environment around them, paying...
