Pie-Pan Convection
Source Institutions
It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.
¡Huellas Digitales!
Source Institutions
En esta actividad, los aprendices leen sobre como Mateo y Cientina conducen una investigación forense para descubrir quien llevó unos dulces.
Magnetic Pendulum
Source Institutions
In this activity about magnetism (page 15 of the PDF), learners will explore how opposite and similar magnetic poles affect a swinging (pendulum) magnet.
Standing in the Shadow of Earth
Source Institutions
This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.
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.
Where Was That?
Source Institutions
In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.
Macromodel of Microarray
Source Institutions
This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.
Finger Reading
Source Institutions
In this activity (10th activity on the page) about the sense of touch, learners make Braille letters out of cork or cardboard and map pins.
The Model Neuron
Source Institutions
In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.
Chemical Breath
Source Institutions
This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.
Pulse of Life: Measure Your Pulse
Source Institutions
In this activity, learners take their own pulse and explore how heart rate is affected by various activities.
Moving Molecules!
Source Institutions
In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw
Magnification vs. Resolution: Can you see the flag on the Moon?
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.
Race to the Top
Source Institutions
In this math game (Page 6 of the Are You Game? PDF), learners examine the probability of rolling sums from 0 to 12 with two dice. The first player to reach the finish line is the winner.
Cooling the Mummy's Tomb
Source Institutions
In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.
What Causes Pressure?
Source Institutions
In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.
From Gas to Liquid to Solid
Source Institutions
What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.
Is It Possible: Estimating Measurement
Source Institutions
In this activity, learners will decide together on a question about how far, long or high the group could reach together.
Gravity-Defying Water
Source Institutions
In this activity, learners explore gravity and air pressure as they experiment with holding a glass full of water upside down, without spilling it, using a simple piece of cardstock.
A Mole of Gas
Source Institutions
In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.
