A wonderful lesson incorporating math and physics skills along with specific details about the planetary bodies. The cross-curricular approach makes for a valid activity to challenge multiple ages and abilities. Your class could work in...

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...

Students review the units of the metric system, and practice estimating measures before actually converting between the two systems of measurement. They participate in activities to visualize a concentration of one part per million....

From quantum foam to the universe itself, plus everything in between, what is the scale of the world around us? Inquisitive physicists grapple with the proportions of all things great and small using a fascinating interactive. Scholars...

Creating a solar system map is a snap thanks to a hands-on activity! Science scholars explore the solar system by building it wherever they choose during an interactive from PBS's Space series. Users pick both the location and scale for...

Launch your class on an exploration of the solar system. Learners construct solar system models to scale and get a better understanding of our place in the vast void of space. This is a great way for them to cement their understanding of...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

Symmetry, line, shape, art, and math are all connected through a fun hands-on craft. Included are instructions to a classic activity, where learners create butterflies to show symmetry in nature and then discuss symmetry in math. It is...

Students research measurements of the moon and Earth as well as the distance between the two in order to create scale models of the Earth-moon system. With a marble to be used as the moon, they must determine how large to make Earth...

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...

Size within the solar system is a difficult thing for pupils to imagine. Using everyday objects, they build models to show the scale between the sun, moon, and Earth. They situate their props in proportional distances between the objects...

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

Outer space may be a lot closer than you think! Science scholars model the layers of the atmosphere using transparencies to gain insight into the scale of space. The resource includes ideas to tailor the activity to the skill level of...

Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

In this chemical reaction principles activity, students read about definite proportions and the law of conservation of mass. Students read about how to balance a chemical equation. Then students complete 20 fill in the blank, 2 short...

Middle schoolers discuss the importance of scaling drawings. In this math instructional activity, students create a scaled drawing of circuit boards. They explain why accuracy is very important when scaling.

Help your class understand the magnitude of the distance between Earth and Mars with an activity that asks small groups to use balloons to create scale models of the Earth, Moon, and Mars. Class members figure out the distances...

Third and fourth graders are introduced to the concept of map scale. Using an illustration, they discuss if it shows the actual size of the object and why scale is used to represent areas. They use some items in the illustration to...

Challenge young astronomers to demonstrate their knowledge of the solar system with this fun open-ended science project. Provided with a short list of requirements, students are given the freedom to use their creativity and whatever...

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

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...

Middle schoolers discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl...

Students measure various dimensions of a male and a female dolls body and scale them proportionally to average human measurements. They calculate the appropriate scale factor (magnitude) to enlarge their doll and apply that scale factor...

Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...
