Students analyze relationship between the increase in polygons sides and a circle. In this geometry lesson, students relate the size of the central angle of a polygon, to a circle. They compare the formula for the area of a polygon and a...

In this science worksheet, students investigate the anatomy and function of the human brain. Students read facts about the parts of the brain and what each does. Students compare the size of the human brain to that of other animals....

In this population worksheet, students will compare two population growth graphs and complete four short answer questions. Then students will investigate the factors that influence population growth in 8 fill in the blank statements and...

For this circle worksheet, students find the area and circumference of circles and compare their size using percents. Students determine the are of composite figures made of circles and rectangles. This one-page worksheet contains six...

In this images of the sun worksheet, students read about the images released by NASA's Solar Dynamics Observatory and they solve 3 problems using the given photograph of the sun. Students find the scale of the image, they compare the...

Students will examine the layers of the Earth. In this geology lesson, students create a scale model of the Earth's interior using cash register tape. They will determine the percentage of error in the scale compared to the actual size...

Students explore parts of an impact crater and compare and contrast craters found in Earth, the Moon, and Mars. Crater formation is modelled and the relationship of mass, velocity, and size of the projectile to the crater formation is...

Fifth graders study the characteristics of fossils. They create a chart comparing the different fossil size, shape and texture. Students make observations and describe fossil characteristics in journals.

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

Young chemists perform an experiment to determine if a compound is iron (II) chloride or iron (III) chloride. Then they determine the formula, balance the equation, and answer analysis questions. 

Eighth graders identify that a ratio is a comparison of two numbers and that a proportion is an equation that equates two ratios. They identify the extremes and means of proportions, as well as the product of the extremes equals the...

Learners decide whether the Reenactment Trek of 1997 parallels the attitudes and challenges of the 1847 Trek.

Fifth graders, in groups, examine different types of apples and how they are different. They also taste the differences of each apple. They use this lesson plan to explore how to make observations.

Students use the FoilSim computer simulation program, and demonstrate an understanding of the lift variables by explaining their graphical representations. They demonstrate an understanding of forces and motion.

Given a picture of "crazy hats," your class will have to determine the different fractions associated with different patterns. Your youngsters will continue practicing their fraction skills with the other word story in this worksheet as...

Students create a self-portrait that is compiled by using individual student drawings. The drawings emphasize line, shape, color and possibly texture depending upon the student's selection of materials.

Learners explore viruses and bacteria. They construct three dimensional models of microorganisms recognizing size relationships by comparing the size of viruses with the sizes of bacterial cells.

Young scholars study bears. For this science lesson, students compare black, grizzly and polar bears. Young scholars measure the bear tracks and compare the bear habitats and diet.

Students work together to create a scale model of the solar system. They write a descriptive paper and a paper comparing and contrasting the Earth to Saturn. They discuss their writings with the class.

In this satellite images activity, students observe two photographs taken by the LRO Satellite of downtown Las Vegas and the moon. They solve 3 problems including  determining the size of craters in the...

Students explain how relatively thin the atmosphere is, compared to the size of the planet, and determine the relative extent of the four major atmospheric layers.

Sixth graders examine how different soils are made up of varying proportions of clay, silt, and sand. They compare soil samples, conduct Internet research, and create a model to demonstrate the relative sizes of grains of clay, sand, and...

Students practice using mathematical issues of scale. They compare and contrast digital images verses the object in real life. They share their observations with the class.

Sixth graders explore characteristics of similar objects. Using attribute blocks, they explore the ratios of the perimeter, area and side length in similar shapes. They calculate and compare the area of shapes.
