Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

Here is an excellent cross-curricular lesson. Learners relate multiplication to area by making a grid on graph paper, and then creating the same grid in real space outside in the school yard.

How does your class measure up? Young scientists create a scale drawing of the JOIDES Resolution in a collaborative activity. The lesson incorporates mathematical principles with deep-sea exploration to focus on enhancing measurement...

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson...

Students discuss the importance of scaling drawings. In this math lesson plan, students create a scaled drawing of circuit boards. They explain why accuracy is very important when scaling.

To gain insight into the many different types of habitats, individuals must first get to know their own. Here, scholars explore their school environment, draw a map, compare and contrast their surroundings to larger ones. They then...

Young scientists gain a better understanding of space, the solar system and its vastness by creating a scale model. Students first need to calculate the distance between each of the nine planets according to the size of their scale. This...

Your class will use a set scale to convert diameters of planets to the model size, the diagram given to expand on the number of planets drawn as concentric circles, and examine the scale that would be needed to fit the larger...

For this Earth and Moon worksheet, students find the ratio of the Earth's radius to the Moon's radius, they compare the diameter of the Earth and Moon, they create paper models to scale of the Earth and Moon and they compare Earth-Moon...

Students create 3-D models of Lake Benthos. In this scale drawing lesson, students create a 3-D model of Lake Benthos. Students work in groups to create the models. Students use the models to to encourage people to conserve natural...

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...

Kids compare what printed text looks like with the naked eye and under magnification. They discuss the extremely small scale that must be used to measure the size. They learn about the micrometer unit, then draw scale models of a variety...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Sixth graders sketch their own kites by creating a scale drawing of an original design.  In this designing kites lesson, 6th graders draw a rough sketch, then accurately draw their design on large paper with a ruler, measuring...

Grouchy? Sad? Here's a great resource that shows kids how music can be used to lift their spirits. Kids collect and chart data on the effects of music on emotions. After analyzing the results of their experiment, they develop...

Create larger-than-life insects for the classroom. Bugs are usually pretty small, but during the Jurassic period they were huge. Kids use diagramming and scale conversion to enlarge a modern day insect so that it is as big as its ancient...

Students measure the actual size and distance of the solar system using scale and ratio. They watch and discuss a video, create a distance-scale solar system model, and compare the scale sizes of planets to their actual sizes.

Learn about damage associated with earthquakes and materials that best withstand a quake. A lab engages class members in the experimental design and construction of sturdy structures that can endure various earthquake...

Middle schoolers complete several projects on the Middle Ages. In this world history lesson, students complete language arts, social studies, math, and science projects. Some of these include: comparing a teenager's life now to that in...

In this scales and galaxies worksheet, high schoolers solve 7 problems including finding the size of galaxies in comparison to other galaxies and drawing scale models of the given galaxies to show their relative sizes and shapes.

Young scholars create a model of an object of their choice using sketches that they have drawn. They study what a scale model is and how to construct one. They examine the uses for scale models and why they are produced.

Aspiring astronomers solve problems involving mixed units of the same attribute, including time, money, length, and area. They convert large numbers into scientific notation, then compute and compare ratios to explain why drawing...

Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; students use grids to make and explain estimates within low and high ranges.

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...
