Gallery of Cells
While all cells have a great deal in common, there is no end to the variation among them. These images provide a sense of the wondrous diversity found in the world of cells.
Energy of Motion
By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated by pendulums and roller coasters. They come to understand that ...
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 activiti
The Growling Stomach
In this lesson, the students will investigate what types of plants and insects they could eat to survive in the Amazon. They will research various plants and/or insects and identify characteristics that make them edible or useful for the trip. The students will create posters and present their findings to the class.
A House is a House for Me
Students brainstorm and discuss the different types of materials used to build houses in various climates. Small models of houses are built and tested against different climates.
Engineering and the Human Body
The Engineering and the Human Body unit covers the broad spectrum of topics that make-up our very amazing human body. Students are introduced to the space environment and learn the major differences between the environment on Earth and that of outer space. The engineering challenges that arise because of these discrepancies are also discussed. Then, students dive into the different components that make up the human body: muscles, bones and joints, the digestive and circulatory systems, the nervo
In this unit, students first are introduced to the historical motivation for space exploration. They learn about the International Space Station and are introduced to new and futuristic ideas that space engineers are currently working on to propel space research. Next, students learn about the physical properties of the Moon. They are asked to think about what types of products engineers would need to design for us to live comfortably on the Moon. Lastly, students learn some basic facts about as
As Charlotte uses her web to communicate, the students will also create a web to send a small message. The students will learn how a spider creates its web, and about the different types of webs spiders make. With this knowledge, the students will design and create their own web and incorporate a message.
Tower Investigation and the Egg
Towers have been a part of developed society for centuries. Towers serve a variety of purposes, from lookouts to cellular towers. In this activity student groups will build three types of towers, engineering them to hold an egg one foot high for 15 seconds.
In this unit, students look at the components of cells and their functions and discover the controversy behind stem cell research. The first lesson focuses on the difference between prokaryotic and eukaryotic cells. In the second lesson, students learn about the basics of cellular respiration. They ...
Weather and Atmosphere
In this unit, students learn the basics about weather and the atmosphere. They investigate materials engineering as it applies to weather and the choices available to us for clothing to counteract the effects of weather. Students have the opportunity to design and analyze combinations of materials for use in specific weather conditions. In the next lesson, students also are introduced to air masses and weather forecasting instrumentation and how engineers work to improve these instruments for at
Forces on the Human Molecule
Students will conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In this activity, students will play the role of molecules in a beam subject to various loading schemes.
When I started teaching this subject I found three kinds of texts. There were applications books that avoid proofs and cover the linear algebra only as needed for their applications. There were advanced books that assume that students can understand their elegant proofs and know how to answer the homework questions having seen only one or two examples. And, there were books that spend a good part of the semester multiplying matrices and computing determinants and then suddenly change level to wo
Something Fishy-Fishing in Ireland Quiz

The user will be enabled to test his/her knowledge on various types of farming in Ireland. The user will be enabled to test his/her knowledge on the products of farming in Ireland. The user will be enabled to develop an understanding of the importance of farming in Ireland as a primary industry.
Language Arts: words for animal groups
Perhaps you knew that sheep come in flocks and cows come in herds? But what about 56 other animal types? This is an exhaustive test of familiar and exotic words for groups of animals. Suitable for secondary school students as well as the general learner and even the wisest of philologists.
16 questions about fictional sleuths. Get those little grey cells going and test your knowledge of great fictional sleuths.
Learn about velocity and acceleration vectors. Move the ball with the mouse or let the simulation move the ball in four types of motion (two types of linear, simple harmonic, circle). See the velocity and acceleration vectors change as the ball moves.
States of Matter
Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.
