Have a Heart
Source Institutions
Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.
Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
Exploring Tools: Special Microscopes
Source Institutions
In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.
Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Jell-O Model of Microfluidics
Source Institutions
This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
Exploring Strange New Worlds
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Wash Away Germs
Source Institutions
Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.
Achieving Orbit
Source Institutions
In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat
Pocket Solar System: Make a Scale Model
Source Institutions
This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.
Biobarcodes: Antibodies and Nanosensors
Source Institutions
In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
Model the Sun and Earth
Source Institutions
In this activity, learners make scale models of the Sun and Earth out of paper mache.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Gumdrop Chains and Shrinky Necklaces
Source Institutions
In this activity, learners thread gumdrops together to make a model of a polymer.
Exploring Earth: Land Cover
Source Institutions
This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
DNA Jewelry Models
Source Institutions
In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.
