In this interactive, learners develop the skills to handle a horse safely before entering the corral for the first time. The interactive consists of three stages, each explaining an aspect of the safety procedures necessary for leading a horse.
The Hot Balloon game lets you control the altitude of the balloon through heating the balloon or releasing air from the air flaps. Hot air rises the balloon through a force called buoyancy. The difference between the outside and the inside air determines the amount of buoyancy. Using weight difference, wind speeds and limited fuel the balloon can go on the farthest rides.
Instructional video on how DNA binding proteins recognize their target sequences in DNA.
Although textbooks describe this process and show illustrations, it is difficult to grasp without seeing a live demonstration.
Created for Biology 41 General Genetics at Tufts University.
This demonstration shows that an increase in temperature will speed up the water cycle. One outcome will be an increase in rainfall. A second outcome will be the increase in total evaporation of water and subsequent drought. Materials required include two aquariums, plastic wrap, 2 clamp lamps with 60 watt light bulbs, pebbles and rocks, modeling clay, blue food coloring, and water. Student worksheets, background information for teachers, and a scoring rubric are included. This is Activity 2 in Too Many Blankets, a module in the lesson series, Potential Consequences of Climate Variability and Change.
This activity is a hands-on modeling of the effects of pollution on our ground and surface water. Students will observe and record their observations as pollution is placed on the ground in their model and it is rained upon.

This activity focuses on the role of photosynthesis in a sustainable future. Students explore the effect of photosynthesis and respiration in a 'closed systems' containing plankton, marine plants, and fish. By calculating carbon dioxide uptake and production in these systems, they predict a plant: animal ratio sufficient to maintain a system in carbon dioxide 'balance' for one hour.

This short investigation from Carbo Europe explores how temperature affects the solubility of carbon dioxide in water.
In this demonstration, students explore the concept of greenhouse warming. They determine whether an increase in the amount of heat-trappping gases in the atmosphere can cause the temperature on Earth to rise. Students compare the relative heat retention in two experimental systems that are identical except for one being covered with plastic wrap. Materials required include two small aquarium tanks, plastic wrap, two clamp lamps with 60 watt bulbs, modeling clay, rocks and pebbles, and two thermometers. Teacher background information, student worksheets and a scoring rubric are included. This is Activity 1 of the module Too Many Blankets, part of the lesson series, The Potential Consequences of Climate Variability and Change.
In this lesson on cosmic rays, students will explain two examples of a cosmic ray detector. Includes information about student preconceptions and a demonstration that requires a geiger counter and optional access to a small radioactive source that emits energetic helium nuclei (alpha particles), e.g., the mineral the mineral autunite, which contains uranium. This is activity two of four from The Cosmic Ray Telescope for the Effects of Radiation (CRaTER).
In this lesson, students will view and analyze both good and bad interview techniques. Students will identify proper dress for a professional interview setting, recognize proper body language and behaviors expected at interviews, and will practice proper communication skills employers are looking for. Interviewing is an important process to gaining quality employment and a problem this lesson will address. Understand proper dress, speech, and behaviors will increase a person's chance of gaining quality employment. Public speaking skills are needed, proper persuasive communication skill, life skills such as proper dress and body language.
An interactive applet and associated web page that provide step-by-step animated instructions on how to measure angles using a protractor. Specifically, it uses a protractor to measure two angles that form a vertical pair, verifying they have the same measure. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
My resource is a paper written on the importance of our actions and how much they impact other people.
What lessons can we learn about genetically engineered organisms from the example of the jabberjay, a fictional bird in the movie “The Hunger Games”? In this lesson, students discuss the definition of genetically modified organisms, learn about the risks and benefits of research on G.M.O.’s, explore the growing do-it-yourself biology movement, and develop proposals seeking to either restrict or permit research into genetically modifying the avian flu virus.
Horizontal drilling and hydraulic fracturing are used to produce oil and natural gas from non-porous rock formations. Use this model to explore how such wells are drilled and fractured to release methane from a layer of shale. Like every energy-extraction process, there is the potential for contamination. Use the model to explore how contamination of aquifers might happen during the hydraulic fracturing process.
HydroViz is an educational "virtual" hydrologic observatory developed for a "real" watershed and is based on integration of field data, remote sensing observations and computer simulations of hydrologic variables and processes. The main purpose of HydroViz is to support hydrology education in engineering and earth science courses.

Explore the polar molecule interactions known as hydrogen bonds. Despite the "bond" name, hydrogen bonds are a special type of dipole-dipole interaction. Hydrogen bonds between two molecules (or within portions of a larger molecule) when hydrogen atoms bonded to highly electronegative atoms (such as nitrogen, oxygen, or fluorine) interact with electronegative portions of a different molecule or within the same molecule. Hydrogen bonds are particularly important in stabilizing large macromolecules, such as proteins and DNA.
This activity is a teacher demonstration of an ice cream model representing glacier movement across Minnesota. Teacher/student questions and discussion should be encouraged during the demonstration.
This is an interactive resource to help train anyone to be more observant and be able to identify suspects in the event a crime has occurred. While this is directed to employees of a financial institution, anyone can use it to increase their powers of observation. This is also a great exercise to give to students to help them become more observant of people and surroundings.
This visualization is a collection of maps, by continent, that project the impact on coastlines of a 216-foot rise in sea level, which is assumed to be the result of melting all the land ice on Earth.
