Tides and gravity labs
How does gravity cause tides in the oceans? This section, part of an interactive laboratory series for grades 8-12, introduces students to four activities on tides and gravity that cover critical orbital speed between Earth and the moon, gravitational forces between two bodies, tidal effects from the sun and moon, and the change in tidal levels over time. The activities include hands-on animations of concepts whose variables can be manipulated by students. Questions posed to students include ans
Science Sampler : The sweet Earth
A great number of geologic processes either take unimaginable lengths of time to complete, or happen in places that cannot be directly observed, such as under the Earth's crust. It is, therefore, necessary for an Earth science teacher to find a connection between students' experiences and the geologic process they are studying to help them better understand that which is often unobservable. One Earth science topic with a tendency to be beyond the reach of direct observation for students is rock
Graphing for Area
Middle School, difficulty level 2. Graph six points and find the area of the resulting hexagon.
The future of energy, efficiency
Energy-efficient appliances and vehicles can greatly reduce the amount of energy Americans use. This informational piece, part of a series about the future of energy, introduces students to the consequences of using energy more efficiently. An example about baking a pie provides students with a practical definition of efficiency. A discussion of energy-efficient appliances and processes follows as students read about the Energy Star label. The overall efficiency of a power plant is described, sh
Observe an animation of volcanism at a subduction zone
This Earth science resource features an animation of the volcanic activity that occurs when an oceanic plate subducts under a continental plate. An introductory paragraph provides background information about the events depicted in the animation. These events include the creation and eruption of magma and the formation of volcanic mountains at a subduction zone. Key features such as the asthenosphere are labeled at the beginning of the animation, and arrows indicate the direction of the oceanic
Uncertainty in the science of climate change
This November 1, 2007 entry in the NSDL Expert Voices blog Connecting News with National Science Education Standards deals with uncertainty in the science of climate change and how scientists deal with it. Though uncertainty is integral to science, few middle school students recognize that. Teachers can use this opportunity to introduce students to uncertainty in science and how scientists account for it. Additional links to teaching resources related to climate change, the nature of science, an
This is a series of experiments about dinosaurs and paleontology that was designed for use in the second grade. Each activity gives the needed materials, what to do, and what to think about. All are designed so the student uses everyday, inexpensive materials and they reinforce information that has already been taught. The Teacher's Notes provide the purpose of the activity, preparation, and notes.
Number and Operations
The study of numbers and operations is the cornerstone of the mathematics curriculum. Learning what numbers mean, how they may be represented, relationships among them, and computations with them is central to developing number sense.
This activity focuses on getting students to think about disabilities and how they can make some aspects of life more difficult. The students are asked to pick a disability and design a new kind of sport for it.
Conducting a Parametric Dependent Samples t-test (Paired Samples t-test)

Who Can Make the Best Coordinate System?
Students will learn about coordinate systems in general by considering questions concerning what it is that the systems should do, and who decided they would look the way that they look. They will attempt to try and make their own coordinate system using a common area across all groups and compete to see who can make the best one. Students then analyze why it is that some systems work better than others and consider what those observations mean for evaluating and choosing geographic coordinate s
Service-Based Engineering Design Projects
This unit describes a general approach to guiding students to complete service-based engineering design projects, with specific examples provided in detail as associated activities. With your class, brainstorm ideas for engineering designs that benefit your community or a specific person in your community. Then, guided by the steps of the engineering design process, have students research to understand background science and math, meet their client to understand the problem, and create, test and
Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood control, irrigation, recreation), and their importance (historically, currently and globally). Through an introduction to kinetic and potential energy, students come to understand how dams generate electricity. They learn about the structure, function and purpose of loc
Designing a Thermostat
Students investigate circuits and their components by building a basic thermostat. They learn why key parts are necessary for the circuit to function, and alter the circuit to optimize the thermostat temperature range. They also gain an awareness of how electrical engineers design circuits for the countless electronic products in our world.
Cellular Respiration and Population Growth
Two lessons and their associated activities explore cellular respiration and population growth in yeasts. Yeast cells are readily obtained and behave predictably, so they are very appropriate to use in middle school classrooms. In the first lesson, students are introduced to yeast respiration through its role in the production of bread and alcoholic beverages. A discussion of the effects of alcohol on the human body is used both as an attention-getting device, and as a means to convey important
Microsoft's Google accusation
Microsoft officially filed a complaint with European Union regulators claiming Google is using its dominant position in Internet search advertising to block competition.
7.2 Developing a strategy Present notes/records that show you have planned your use of skills to work with others. Your evidence must include: the goals you hope to achieve over 3–4 months or so; you should indicate how these goals relate to the context in which you are working and to your current capabilities; notes/records about the resources you might use and what information you need to support you in developing your skills and completing the work; for e

Diffusion and Adoption of OER
Its time for a no-holds barred match to see who was right Aristotle or Galileo as we answer the question.. Do heavier objects fall faster than lighter objects? And, of course, what Mr. O video would be complete without something just plain ridiculous like say dropping water balloons off a 20+ foot balcony. (Yes, it was fun, but dont try it at home kiddies!). (05:31)
