Scale/Ratio
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...

Using Map Scales to Figure Distances and Areas
The asteroid is getting closer and the question is whether the state of Alabraska is large enough for the shelter calculated in the previous activity. Teams determine the scale of their project and then use the scale on the map to...

The Earth and Moon to Scale
In this Earth and Moon instructional activity, 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...

Scale Model of the Solar System
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...
Curated OER
Galaxies to Scale
In this scales and galaxies activity, students 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.
Curated OER
Dimensions of the Solar System
A set of instructions that help learners draw concentric orbital arcs to scale of each planet. There is a table to complete with data and questions to check understanding of realistic orbits and relative sizes.
Exploratorium
Life Size - Explore the Size and Scale of Microscopic Biology
Compare sizes of microscopic items. Given a set of labels of microscopic objects, pupils try to place them in order from smallest to largest. Scholars then compare their lists to the actual comparisons along with the measurements of the...
Journey Through the Universe
Voyage of Discovery
Did you know that Pluto is smaller than the United States of America? It is difficult to conceptualize the size of planets and the distance between them, and the lesson addresses those exact issues. After a discussion, pupils create...
Curated OER
Exploring Scale And Ratio
Learners 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.

Mapping the Bone Field: An Area and Scale Exercise
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.
Polar Trec
Drawing Diatoms like Ernst Haeckel
Why do scientists rely on drawings rather than just photographs of their research studies? The lesson introduces drawings of microscopic organisms and the importance of accuracy. Young artists draw organisms and learn why focus and...

Scale Drawings of Birds
Students create their own copies of Phoenix Birds using a grid system.

Packing for a L-o-o-o-ng Trip to Mars
Pack just enough to fit. Crews determine what personal items to take with them on a trip to Mars. Each team must decide what to take with them on a two-and-a-half year trip to Mars and whether their items will fit within the allotted...
NOAA
To Explore Strange New Worlds
It's time to boldly go where your class has not gone before! The introductory instructional activity in a five-part series takes young oceanographers aboard the NOAA Ship Okeanos to begin a study of ocean exploration. The instructional...

Designing a Hiking Trail
Put your students' map skills to the test with this engaging cross-curricular project. Given the task of developing new hiking trails for their local community, young cartographers must map out beginner and intermediate...
Curated OER
Build an Approximate Scale Model of an Object
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.

Planet Scaling using Extra Terrestrial Tools
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...

Making Models To Understand Our Home
Students investigate the concept of a model and how it is used to represent something that is real. They recognize how the model can be applied to other types of concepts like the solar system. Students create a scale drawing of a house...

Nano What?
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....

Footprints: Take a Step into Estimation
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.

Megabeasts
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...

Historical Climate Cycles
What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over...
