In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

This game explores the different reasons we choose to eat, and helps us be aware of when our body needs food and when it does not.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this activity, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this matching activity (3rd activity on the page), learners use their sense of smell to match pairs of opaque containers filled with various smelly items like orange peel, roses, or moth balls.

In this activity (on pages 19-24 of PDF), learners soak chicken bones or eggshells in vinegar for several days.

In this outdoor simulation game, learners search for pretend animals called "sticklers" to determine and map where they live (habitat) and how spread out they are in that area (distribution).

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.

Get all wrapped up in a lesson about skin!

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this activity, learners compare ways to measure their heart rates. Learners build their own stethoscopes and learn how exercise affects heart rate.

In this creative outdoor activity, learners invent populations of make-believe organisms and then investigate real populations living in the activity site.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

Sound changes pitch relative to how you or the source of the sound is moving. Use this simple activity developed by the Exploratorium to experience the Doppler Effect yourself!
