How many planets can you name? Did you get all 13 in our solar system, including the dwarf planets, or were you surprised when you read there are 13 planets? The activity helps scholars understand the scale of the universe including the...

Can we model how large the solar system really is? Attempt an astronomical feat with a hands-on-activity that uses a roll of toilet paper. Young scientists measure the distances of the planets from the sun to create a scale model of...

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...

How in the world can something as big as the solar system possibly fit in your pocket? Complete this simple modeling activity and find out, as young scientists gain an appreciation for the incredible scale of outer space.

Extremely large or extremely small numbers are difficult to comprehend. To help understand the massive scale of the solar system, learners complete two activities. First, they create a model to compares the size of the bodies in the...

Scholars go on a hunt to locate objects that best fit the measurements to create an eye-catching scale model of the solar system. 

Create a scaled model of our solar system in your classroom! Scholars work collaboratively to build paper mache planets and hang them in their proper position to showcase each planet's location in the solar system.   

Ever wonder why Pluto isn't considered a planet? Or how large the Earth is compared to the other inner planets? Explore the universe with a series of projects that simulate different aspects of our solar system. The activities require...

Why do scientists use models? In the first installment of 22, groups create scale models of our solar system. They then share and discuss their models.

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...

The moon orbits Earth while the Earth is rotating, and the Earth revolves around the sun. This can be a tricky concept for young astronomers. Implement an activity that helps distinguish between the movements of Earth's systems around...

Don't just look at pictures of the Milky Way galaxy, build it with this hands-on activity in which scientists recreate the galaxy we live in.

Since you can't go to the comet, bring the comet to you. Young scientists build models of comets using everyday materials and then participate in a simulation of the interaction between the comet and other bodies in the solar system....

How can December 21 be the shortest day of the year when all days are 24 hours long? Pupils see how to build a model showing the differences between winter and summer solstices and equinoxes. Using this model, classes can then discuss...

Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this activity builds off of that concept by having pupils use a data table to create their own scale models of the interiors...

Since a field trip to the moon isn't possible, bring the moon to young astronomers! Participants use everyday materials to create models of the moon and represent the features on its surface. The materials serve as a tactile as well as a...

Get to know our galaxy with an astronomy-themed, hands-on activity. Scholars watch an informative video, answer questions, and construct a model of the Milky Way in order to examine its contents and the distance inside it.  

The sun isn't just a ball of yellow! Young scientists learn about the features of the sun using a hands-on modeling activity. They build models of the sun using common household items to represent sunspots, solar prominence, and the...

On September 26, 1991, four women and four men entered the scientific experiment, Biosphere 2; the doors were sealed for two years in order to study the interactions of a biosphere. In the activity, scholars explore biospheres by...

Can people really measure time just by using the sun? Scholars venture outside on a nice, sunny day to build sundials and learn how people measured time 600 years ago. The class builds two different sundials while gaining practice with...

Protect the marshmallows! Groups create contraptions that will keep marshmallows in a cup, even after dropping them from a certain height. This is a fun way to model the shock-absorbing capabilities of spacecraft.

Comets are also known as dirty snowballs or icy mud balls. With your super scientists, create a model comet nucleus to discover how they are made and take part in a scientific discussion to learn how it behaves.

Investigate invisible forces. Young engineers design a setup that changes the direction of a steel ball using a magnetic force. The purpose of the setup is to model the gravitational pull of spacecraft by planetary bodies.

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...
