In this lesson, students collect, grow, observe and compare bacteria and/or fungi in petri dishes, learning that microbes are everywhere and can grow rapidly on sources of food and water.
In this lesson, students read about six milestones in the history of ...
In this lesson, students read about six milestones in the history of microbiology, create a timeline of events, and learn that many scientific advances become possible only after appropriate tools and techniques have been developed.
In this lesson, students read an essay, "Portrait of a Killer," about ...
In this lesson, students read an essay, "Portrait of a Killer," about the emergence of HIV/AIDS, and learn about the basic structure of the virus by making three-dimensional paper models of an HIV particle.
In this lesson, students learn about the nutritional needs of our bones ...
In this lesson, students learn about the nutritional needs of our bones and muscles, and how to make healthy food choices, especially in terms of getting enough calcium.
In this lesson, students investigate the relationship among mass, acceleration and force, ...
In this lesson, students investigate the relationship among mass, acceleration and force, as described in Newton's laws of motion. Students will work in collaborative teams to use a wooden car and rubber bands to toss a small mass off the car. The car, resting on rollers, will be propelled in the opposite direction. During a set of experiments, students will vary the mass being tossed from the car and change the number of rubber bands used to toss the mass. Students will measure how far the car rolls in response to the action force generated.
In this lesson, students learn about healthy eating habits to meet special ...
In this lesson, students learn about healthy eating habits to meet special lifestyle needs, such as those of athletes, persons with diabetes and vegetarians.
In this lesson, students construct paper rockets and evaluate their rockets' flight. ...
In this lesson, students construct paper rockets and evaluate their rockets' flight. Following the flight of the rockets, students reconsider their rocket designs, make modifications, and fly the modified rockets to determine if the changes affected rocket performance. Students conclude the activity by writing a post-flight mission report.
In this STEM lesson, students will use the engineering design process to ...
In this STEM lesson, students will use the engineering design process to design and construct rocket-powered racing cars with which to investigate Newton's Laws of Motion. Each student will construct his or her own car from food trays, and will use inflated balloons to power the car (thrust). Students conduct three trials and measure the distance traveled by the cars. Between trials, students modify their designs to improve performance and solve any "mechanical" problems that crop up. At the conclusion of the activity, students submit a report on their racer design and how it performed in the trials.
In this activity, students are introduced to the concept of "calorie" and ...
In this activity, students are introduced to the concept of "calorie" and compare the relative amounts of energy in similar-sized portions of a carbohydrate-based food and a food rich in oils.
In this activity, students are introduced to the relationship between food and ...
In this activity, students are introduced to the relationship between food and energy. Students will observe what happens when yeast, a single-celled fungus, is provided with food (table sugar).
In this activity, students document their individual eating habits, examining serving size ...
In this activity, students document their individual eating habits, examining serving size and calories, and learn whether these dietary patterns meet their nutritional needs.
In this lesson, students learn about the skeletal system by designing and ...
In this lesson, students learn about the skeletal system by designing and building an exoskeleton or endoskeleton for an animal of their own invention.
In this lesson, students learn about endoskeletons by observing, comparing and contrasting ...
In this lesson, students learn about endoskeletons by observing, comparing and contrasting different kinds of chicken bones, and by relating their chicken bon observations to human bones.
