Building Tetrahedral Kites
Working in teams of four, students build tetrahedral kites following specific instructions and using specific materials. They use the basic processes of manufacturing systems – cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control – to manufacture complete tetrahedral kites within a given time frame. Project evaluation takes into account team efficiency and the quality of the finished product.
The Mummified Troll: Devising a Protection Plan
Students are introduced to the parameters of an engineering challenge in which their principal has asked them to devise an invisible security system to cost-effectively protect a treasured mummified troll, while still allowing for visitor viewing during the day. Students generate ideas for solving the grand challenge, first independently, then in small groups, and finally, compiled as a class.
Will It Fly?
In this lesson, students will learn about kites and gliders and how these models can help in understanding the concept of flight. Students will design and build their own balsa wood models and experiment with different control surfaces. The goal of this lesson is for students to apply their existing knowledge about the four forces affecting flight and apply engineering design to develop a sound glider. They will also communicate the reasoning and results of any design modifications made.
Power, Work and the Waterwheel
Waterwheels are devices that generate power and do work. Students construct a waterwheel using two-liter bottles, dowel rods and index cards, and calculate the power created and work done by them.
Design Your Own Rube Goldberg Machine
Engineer and cartoonist Rube Goldberg is famous for his crazy machines that accomplish everyday tasks in overly complicated ways. Students use their new understanding of types of simple machines to design and build their own Rube Goldberg machines that perform simple tasks in no less than 10 steps.
The Boxes Go Mobile
To display the results from the previous activity, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved.
The purpose of this activity is to demonstrate some of the different parts of an airplane through the construction of a paper airplane. Students will build several different kinds of paper airplanes in order to figure out what makes an airplane fly and what can be changed to influence the flying characteristics of an airplane.
A Merry-Go-Round for Dirty Air
Students observe and discuss a cup and pencil model of a cyclone to better understand the science behind how this pollutant recovery method functions in cleaning industrial air pollution.
Engineering for the Earth
Young students are introduced to the complex systems of the Earth through numerous lessons on the Earth’s natural resources, processes, weather, climate and landforms. Key earth science topics include rocks, soils and minerals, water and natural resources, weather patterns and climatic regions, wind, erosion, landforms, and the harvesting of fossil fuels — all presented from an engineering point-of-view. (See the Unit Overview section for a list of topics by lesson.) Through many hands-on ac
History to Enrich Mathematics Learning
This resource guide highlights online resources that talk about the history of mathematics in a way that can help students see real-world connections in mathematics.
Edd Presnell: Dulcimer Maker
Edd Presnell, a mountain craftsman and native of Watauga County, North Carolina, demonstrates and comments on the construction of a dulcimer. Presnell learned his craft from his father-in-law. Film includes a brief performance on a finished dulcimer by his wife, Nettie. This 16mm film is archived in the Thomas G. Burton and Jack Schrader collection in the Archives of Appalachia, East Tennesse State University.

Ready, Set, SCIENCE!: Putting Research to Work in K-8 Science Classrooms
What types of instructional experiences help K-8 students learn science with understanding? What do science educators teachers, teacher leaders, science specialists, professional development staff, curriculum designers, school administrators need to know to create and support such experiences? Ready, Set, Science! guides the way with an account of the groundbreaking and comprehensive synthesis of research into teaching and learning science in kindergarten through eighth grade. Based on the recen
The lemon battery challenge
In this activity, students will learn how a chemical reaction can produce electricity. Learners will create a wet-cell battery to determine how much power it takes to run an electric car.
Green Science: Investigating green—Creating surveys to answer questions
Being green means different things to different people. Some suggest that being green means saving energy, not wasting paper towels, going solar, harnessing wind, using less fertilizer, or buying products that are organically grown. Given that being green can mean a lot of things, what does “being green” or “going green” mean to both you and your students? To find out, we need to make informed decisions by collecting data. Therefore, the purpose of this article is to become familiar with
Learning about Multiplication Using Dynamic Sketches of an Area Model
Students can learn to visualize the effects of multiplying a fixed positive number by positive numbers greater than 1 and less than 1 with this tool. Using interactive figures, students can investigate how changing the height of a rectangle with a fixed width changes its area.
Explore a few of the ways plants pollinate each other in this video segment from Sexual Encounters of a Floral Kind.

Male Weedy Seadragon Carrying Eggs on Abdomen
This very short video gives excellent real life, close up footage of a male Weedy Seadragon carrying eggs on his abdomen. Weedy seadragons are one of only two species of seadragons, the second is known as the leafy seadragon (Phycodurus eques) due to the greater number of leaf-like appendages along its body. Seadragons resemble the seahorses to which they are related, having a bony-plated body and elongated snout; their tails are not prehensile however. This is a great resource to help buil
Professor Germaine Greer - An Insight - Full Interview
Warning: Explicit Content Professor Germaine Greer delivered the 2010 Winifred Mercier public lecture at Leeds Met on Tuesday March 23. Born in Melbourne and educated in Australia and at Cambridge University, Professor Greer's first book, The Female Eunuch (1969), took the world by storm and remains one of the most influential texts of the feminist movement. She has had a distinguished academic career in Britain and the USA and makes regular appearances in print and other media as a broadcast
