Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
DNA Fingerprinting
Source Institutions
In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.
Mixtures and Solutions
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce
Rocket Science
Source Institutions
Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.
The Water (Hydrologic) Cycle: Transpiration
Source Institutions
In this lab, learners grow broad bean (also called fava bean) plants in three EarthBoxes for a few weeks before exposing one to wind (using a fan), another to heat (using a lamp), and the third to not
How Do We Convert Electrical Energy into Mechanical Energy?
Source Institutions
In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.
Using Solar Energy
Source Institutions
In this activity, learners discover how solar energy can be used to heat water.
Newton Car
Source Institutions
In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.
Geothermal Power Plant Model
Source Institutions
In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
Strong Bones, Weak Bones
Source Institutions
Most people will break a bone in their body at some point in their life, but how much force does it take to break one?
Build a Battery
Source Institutions
Learners build a simple one-cell battery and use an ammeter to measure the flow of current.
Experimenting with Naked Eggs
Source Institutions
In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.
DNA Extraction from Wheat Germ
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.
Floating Candles
Source Institutions
In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.
Hot and Cold
Source Institutions
In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.
Visualizing How the Vestibular System Works
Source Institutions
In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the
Ziptop Bag Chemistry
Source Institutions
In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.
