Antibody Attack - Discover How Antibodies Launch Attacks on Invaders
Jump into the action and help antibodies defend against an antigen attack! Investigators match antibodies with antigens to model the body's identification and recall of specific pathogens. Young biologists also recognize that each...
Exploratorium
Skin Shield - Explore the Body’s First Line of Defense Against Pathogens
Make pathogens and the body's defense systems come alive for young biologists in a hands-on activity. Investigators model the skin's protection against infection by observing and comparing changes in a punctured tomato and an intact...
Exploratorium
Secret Codon - Write a Message in DNA
String up a message. Pupils string together colored beads to code a word or short phrase. Each color represents one of the four DNA bases. Using a combination of three bases, learners create an amino acid that stand for each letter of...
Exploratorium
Breakfast Proteins - Construct a Protein through Cereal Additions
Match my cereal sequence. Pupils view a sequence made by colorful cereal rings and create copies of it. Learners must either remember or write down the sequence to transport the code to another location. Scholars replicate the cereal...
Exploratorium
Life Size - Explore the Size and Scale of Microscopic Biology
Compare sizes of microscopic items. Given a set of labels of microscopic objects, pupils try to place them in order from smallest to largest. Scholars then compare their lists to the actual comparisons along with the measurements of the...
Exploratorium
Cellular Soap Opera - Soap Films Can Behave Like Membranes
Soap, suds, and cell membranes. Pupils create a model of a cell membrane by using soap films. They experiment with trying to pass different objects through the film without popping it. Using a tube, they create a passageway through the...
Exploratorium
Viral Packaging
Create a protective protein shell as a package. Using the included template, pupils tape together 20 triangles to create a 20-sided shape to represent the protective shell of a virus. The model of the protein shell incases the nucleic...
Exploratorium
Traveling Networks
Show your class the path to understanding graph theory. Scholars learn about basic graph theory using an activity based on the Bridges of Konigberg problem. They draw networks on the playground and decide whether it is possible to travel...
Exploratorium
Measuring and Mapping the Playground
The school playground is a great place to learn about math. Pupils measure the dimensions of a playground using baby steps and individual strides. They use their measurements to create a scale drawing of the playground by applying an...
Exploratorium
Angle Hunting
Do angles change with distance? Using a previously made tool, individuals find and measure angles on a playground. They observe that angles are the same measure regardless of the distance at which they're measured.
Exploratorium
Handy Measuring Ratio
Your hand can be a handy tool for measurement. Young mathematicians learn how to estimate the height of objects by applying similarity. They find the horizontal distance from the object where spreading their outstretched fingers results...
Exploratorium
Stride Ruler
Take it all in stride! Scholars learn to estimate distances using their strides as measurement. They take 10 steps next to a set of meter sticks and use the final distance to estimate the length of each step. Once they've found the...
Exploratorium
Making a Translation Tesselation
Make masterful art using math. An interesting activity has learners create artwork involving tesselations. First they cut out a base shape from index cards, then they apply translations to complete their masterpieces.
