Students view a video about viruses, how they infect, and how the body defends against them, then learn the basics about HIV. In an associated activity, students will create a card game to clarify the specific ways that HIV is transmitted.
Students explore Newton's first law of motion. In the associated activity, students will experiment with variable speeds and distances to see how far and how fast they can throw an egg without breaking it.
Students learn about air pressure and how changes in atmospheric pressure can relate to weather patterns. Students will demonstrate air pressure in an associated activity.
Students view a video about antibiotics and learn how they work to kill bacteria. In an associated activity, students will demonstrate how antibiotics work and how antibiotic-resistant bacteria can survive a medication's actions.
Students learn about the types and amounts of food that Arctic explorers eat in order to get the energy they need to complete an expedition. In an associated activity, students will collect food labels from the different foods they eat and analyze the labels to discuss the calorie and nutrient information for each one. In the culminating activity, they will plan an appropriate meal list for a seven-day Arctic expedition.
Students learn about the physics behind how a bicycle works. In an associated activity, students find out how to bike more efficiently by calculating gear ratios.
Students learn about fats and how excessive fat and calories in the diet can contribute to health problems. In an associated activity, students will plan a three-day backpacking trip to the Rocky Mountains based on their understanding of the need to balance supply of and demand for calories.
Students learn about drinking water - where it comes from, why and how it is treated before municpal use, and how ocean water distillation may be used to alleviate water shortage problems in some communities. In an associated activity, students will build a device to distill seawater to create drinking water and discover some of the costs associated with producing freshwater from the sea.
Students learn about the use of ethanol as an alternative fuel source. In an associated activity, students test a variety of substances to see which ones are easiest to ferment for fuel.
This video will help students understand the nomination process for political parties. They will learn how primaries and caucuses help determine the candidate that will best represent a party platform, the role of delegates and super delegates in the election process, and the impact of "Super Tuesday."
Students learn about glass and how it is made, and how this affects it use, especially as related to technology. In an associated activity, students investigate butter and compare it to glass.
Students learn about infrared radiation. In an associated activity, students compare the behavior of a beam of infrared radiation to that of a beam of visible light and make observation when different materials are placed in its path.
In this lesson, students will examine some of the mistakes and misjudgments made by the British that led to the failure to win the Revolutionary War. Students will understand the major developments and chronology of the Revolutionary War. They will also investigate the social and economic impact of the war, including economic contributions of European nations and how their involvement influenced the war's outcome and aftermath.
Students learn about the phsyics behind the Olympic luge event. In an associated activity, students will design and build super fast luges and exciting luge courses to investigate forces and friction. Students will run several time trials and collect and record data, then graph the results.
Students learn how the plants in the rain forest are specially adapted to life in the rain forest. In an associated activity, students work in small groups to investigate how buttressed roots work.
Students learn about the process of wastewater and sewage treatment. In an associated activity, students will observe what happens when different sized particles are settled in water by creating a model sedimentation tank to see how sludge and effluent are separated.
Students learn about the physics behind a ski jump. In an associated activity, students demonstrate the conversion between gravitational potential energy and kinetic energy by investigating how to launch a projectile as far as possible.
