In this activity (pages 26-29 of the PDF), learners investigate how they can develop super memories by using mnemonic devices.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

In this activity, learners investigate procedural memory.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

Learners use scientific processes to solve a crime. As they get clues, learners must create a hypothesis then adjust that hypothesis as more information is revealed.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this activity, learners perform a simulated blood test procedure.

This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

In this activity, learners will determine if the frequency and intensity of hurricanes are changing using real data from the National Hurricane Center.

Create a simple dual pendulum and get them to swing in identical ways. This is a simple, low cost, activity produced by the Exploratorium.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.
