Teenage girls learn computational design in a collaborative weeklong workshop at the New York Hall of Science.
Learn how insects have inspired engineers to make a robot that walks on the surface of water. Design your own water-walking critter using thin wire, and test its effectiveness: how many paperclips can it hold up using surface tension?
In this activity from Bedtime Math, you'll build a stuffed-animal zip line and practice measuring time, distance, and angles.
Watch an interview with a couple who built a home from shipping containers. Then, design and construct a scale model of a unique shipping container home using printed templates, and estimate the cost of flooring and paint based on model dimensions.
Use the physical characteristics of ice to determine where and how several mystery samples could have been frozen.
Perform an experiment to determine whether smooth or wrinkled fingers are better at holding wet objects. The experiment requires only a water bottle, paperclip, and plastic ruler. Downloads: Video, student data sheet, illustrated instructions
By building their own pinhole camera, students will learn how cameras, telescopes, and their own eyes use light in similar ways.
Explore color by creating color-filtering glasses using paper and tinted cellophane.
In this activity, students will conduct a series of hands-on experiments that will demonstrate how the working of these veins, known as capillary action, enables water to travel throughout the length of a plant. Students will learn how the forces of water...
Use household materials to investigate and explore their ability to smell an odor. Students will compare and contrast results to determine if some individuals have a better sense of smell than others. Students also will observe the Maillard reaction and ...
In this activity, students will discuss the differences between the Bear Creek Wind Park and Bergey Windpower turbines. Students will learn the basic parts of a wind turbine and then build their own model wind turbine out of recyclable materials. Students...
In this lesson, students will be amateur mycologists--collecting and analyzing various mushrooms. Through observation and discussion, students will gain knowledge of the basic anatomy of mushrooms, their life cycle, and their method of reproduction throug...
In this activity, students will sort and classify interactions between pairs of organisms under the appropriate symbiotic relationship of commensalism, parasitism, and mutualism. Then students will observe mutualism in action, as they perform a termite di...
In this activity, students will observe three “mystery” mammal skulls and compare and contrast the features of each skull. Students will learn the anatomical terms for skull features such as orbits, nasal passages, and foramen magnum. Students will learn...
In this activity, students will learn how to prepare deep well slides for observing two types of microorganisms called Paramecium (a group of protozoa, or single-celled organisms, which move with cilia, so they are called “ciliates”) and Euglena (microorg...
In this activity, students will research general information about bettas and use that information to determine suitable habitat requirements and maintenance. Students will work collaboratively to perform weekly maintenance duties to keep their betta aliv...
Geologists are greatly interested in minerals because they can reveal an enormous amount about the history of the geologic environment in which they are found. Geologists can classify and identify minerals by observing various properties such as strea...
In this activity, students review how human physical traits, such as eye color, are determined by specific segments of genes. Students will use basic crafts materials to build a simplified model of a pair of chromosomes that represents some of their own p...
