Students are introduced to the concepts of digital organisms and digital evolution. They learn about the research that digital evolution software makes possible, and compare and contrast it with biological evolution.

This article provides an overview of orienteering and geocaching as well as suggestions for incorporating these activities into elementary classrooms

This outstanding website provides an excellent variety of hands-on earthquake activities to help you understand what causes earthquakes.

In this activity, students will explore two given websites to gather information on Bone Mineral Density and how it is measured. They will also learn about X-rays in general, how they work and their different uses, along with other imaging modalities. They will answer guiding questions as they explore the websites and take a short quiz after to test the knowledge they gained while reading the articles.

This activity allows students to demonstrate their understanding of the Law of Conservation of Energy in the framework of student-designed investigations.

Students will review their knowledge of tension and focus on tensile loads and failure caused by them.

In this activity, participants will imagine the challenges and opportunities of asteroid mining. Participants will draw their own asteroid mining machines, and consider how these devices would extract, process, and return mined materials to Earth. They can also assume roles assigned by the activity's challenge cards, and imagine what concerns or priorities they might have as a scientist, explorer, lawyer, or engineer. While the technologies necessary for mining materials from asteroids do not yet exist, current missions exploring and studying asteroids may lay the groundwork for future asteroid mining operations. Educators should begin with the file named: Asteroid Mining - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Tablet or Smartphone.

In this activity, the students will develop a briefing for a T.V. evening news program that summarizes their experiences surviving in the Amazon rainforest. The students will have the opportunity to role play as interviewer and interviewee in presentations to the class.

A collection of 52 STEM activities and experiments for learners in PreK to Grade 8+ which are separated into Science, Technology, Engineering, and Mathematic subject areas (13 activities each). Each card includes materials list, instructions, reflection question, and a fun fact, tip, or extension.

A collection of 40 STEM activities and experiments for learners in PreK to Grade 8+ which are separated into Science, Technology, Engineering, and Mathematic subject areas (8-12 activities each). Each card includes a materials list, instructions, reflection question, and a fun fact, tip, or extension.

Students conduct experiments to determine the flow rate of faucets by timing how long it takes to fill gallon jugs. They do this for three different faucet flow levels (quarter blast, half blast, full blast), averaging three trials for each level. They convert their results from gallons per second (gps) to cubic feet per second (cfs).

All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.

Working individually or in groups, students explore the concept of stress (compression) through physical experience and math. They discover why it hurts more to poke themselves with mechanical pencil lead than with an eraser. Then they prove why this is so by using the basic equation for stress and applying the concepts to real engineering problems.

Using the LEGO® NXT robotics kit, students construct and program robots to illustrate and explore the Fibonacci sequence. Within teams, students are assigned roles: group leader, chassis builder, arm builder, chief programmer, and Fibonacci verifier. By designing a robot that moves based on the Fibonacci sequence of numbers, they can better visualize how quickly the numbers in the sequence grow. To program the robot to move according to these numbers, students break down the sequence into simple algebraic equations so that the computer can understand the Fibonacci sequence.

In this activity, the students will investigate a variety of plants and animals common to the Amazon through research. They will determine the plant or animal characteristics that make them edible or useful for the trip and learn to categorize them by comparing similarities and/or differences.

This video segment adapted from NOVA explains how the sprinkler revolutionized fire safety and also features developments in fire-safety design for high-rise buildings.

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a lighter fluid. In both cases, they see and record beautiful fluid motion. Activities are also suitable as class demonstrations. The natural beauty of fluid flow opens the door to seeing the beauty of physics in general.

Students experience firsthand one of the most common water treatment types in the industry today, flocculants. They learn how the amount of suspended solids in water is measured using the basic properties of matter and light. In addition, they learn about the types of solids that can be found in water and the reasons that some are easier to remove than others. Encompassing the concepts of force and motion, attraction and repulsion of charged particles, and properties of matter, during the associated activity students see scientific concepts they already understand through the eyes of engineers who apply them to the removal of solids from water via chemical flocculants.

Students design and create flow charts for the MIT App Inventor tutorials in this computer science activity about program analysis. In program analysis, which is based on determining the behavior of computer programs, flow charts are an important tool for tracing control flow. Control flow is a graphical representation of the logic present in a program and how the program works. Students work through tutorials, design and create flow charts about how the tutorials function, and present their findings to the class. In their final assessment, they create an additional flow chart for an advanced App Inventor tutorial. This activity prepares students with the knowledge and skills to use App Inventor in the future to design and create Android applications.
