Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
False Memories
Source Institutions
Use this activity (10th on the page) to help learners explore memory and how sometimes your brain makes up its own memories. Learners will read and try to remember the words in list #1.
Morphing Butterfly
Source Institutions
In this activity, learners explore how nanosized structures can create brilliant color.
Robot Hands
Source Institutions
This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.
The Space Place
Source Institutions
In this activity (23rd on the page), learners conduct an experiment to examine memory and learning.
Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
Shape Up!
Source Institutions
In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each
An Ice Lens
Source Institutions
In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.
Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.
Synaptic Tag
Source Institutions
In this outdoor activity, learners review the parts of the synapse and their functions by playing a game.
Secret Codon
Source Institutions
In this activity, "write" a secret message in genetic code as beads on a string.
Planaria Fishing
Source Institutions
In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.
Arctic Sea Ice
Source Institutions
In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.
Flashy Fish
Source Institutions
Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.
Let's Count Humpback Whales: Environmental Effects on Population
Source Institutions
In this activity, learners use whale count data from the Hawaiian Islands Humpback Whale National Marine Sanctuary to compare whale counts in relation to environmental factors.
Lagging Sound
Source Institutions
In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.
Feeling Pressured
Source Institutions
In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.
The Stroop Effect
Source Institutions
In this activity, learners experiment with the Stroop Effect by challenging themselves and others to try and read a list of colors as quickly and accurately as possible, with a twist.
Memory Solitaire
Source Institutions
In this online game, learners practice memory recall. They are shown a collage of pictures for two minutes, then have to write down everything they remember and check how they did.
Ambiguous Cube
Source Institutions
In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.
