Crossing the Synaptic Gap
Source Institutions
In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.
The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.
The Rumblin' Road: Determining distance to a Thunderstorm
Source Institutions
In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.
Cup Sailing Game
Source Institutions
In this online Flash game, learners will captain a sailing challenge, adjusting boat direction and sails, seeking the way to take greatest advantage of varying wind speeds and directions to catch the
Whose Fault Is It?
Source Institutions
In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
Kid Machine
Source Institutions
This activity is on page 3 (continued on page 2) of the pdf, part of the Simple Machines Discovery Box. In this fun activity, learners "create" a complex machine by simulating the parts in action.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
My Solar System
Source Institutions
In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.
Jump for the Moon
Source Institutions
In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.
Build a Soundscape
Source Institutions
This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.
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.
The Great Balloon Race
Source Institutions
In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.
The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
Sound Representation: Modems Unplugged
Source Institutions
In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.
Do a Spacewalk!
Source Institutions
In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim
Crew Strength Training
Source Institutions
In this activity, learners will train to develop upper and lower body strength in their muscles and bones by performing body-weight squats and push-ups.
pH Scale
Source Institutions
In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
Masses & Springs
Source Institutions
In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.
Can Crushers
Source Institutions
In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.
