Virtual Labs
The Virtual Labs Series produced by the Howard Hughes Medical Institute (HHMI) has won top honors in the Pirelli INTERNETional Award competition. More than 1,200 multimedia entries competed for the Top Pirelli Prize, which recognizes the best multimedia products designed to use the Internet to educate about science and technology. Read on...

The lab will familiarize you with the science and techniques used to make transgenic flies. Transgenic organisms, which contain DNA that is inserted experimentally, are used to study many biological processes. In this lab, you will create a transgenic fly to study circadian rhythms.

The purpose of the lab is to familiarize you with the science and techniques used to identify different types of bacteria based on their DNA sequences. Not long ago, DNA sequencing was a time-consuming, tedious process. With readily available commercial equipment and kits, it is now routine. The techniques used in this lab are applicable in a wide variety of settings, including scientific research and forensic labs.

The focus of this lab is on heritable diseases of the heart. You are cast here as a virtual intern to accompany a doctor examining three different patients. Each patient is examined using more than one diagnostic tool, and at each stage, the doctor will invite you to examine the patient yourself and ask for your opinion.

Record electrical activities of individual neurons while you deliver mechanical stimulus to the attached skin. Inject fluorescent dyes into the neurons to visualize their morphology. Identify the neurons based on the morphology and the response to stimuli, comparing them to previously published results.

Components of the immune system called antibodies are found in the liquid portion of blood and help protect the body from harm. Antibodies can also be used outside the body in a laboratory-based assay to help diagnose disease caused by malfunctions of the immune system or by infections.
This virtual laboratory will demonstrate how such a test, termed an enzyme-linked immunosorbent assay (ELISA), is carried out and show some of the key experimental problems that may be encountered.

4A The Universe #3
Nine planets of very different size, composition, and surface features move around the sun in nearly circular orbits.... 

4G Forces of Nature #2
The sun's gravitational pull holds the earth and other planets in their orbits, just as the planets' gravitational pull keeps their moons in orbit around them.... 
   

10A Displacing the Earth from the Center of the Universe #2
Telescopes reveal that there are many more stars in the night sky than are evident to the unaided eye, the surface of the moon has many craters and mountains, the sun has dark spots, and Jupiter and some other planets have their own moons.... 
   

11B Models #1
Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly, or that are too vast to be changed deliberately, or that are potentially dangerous.... 
   

Planet Size Comparison
Mercury is the second smallest planet; only Pluto is smaller. In fact, Mercury is not much larger than our moon. In this animation, you can find out how Mercury "sizes up" to Earth or any other planet. The first two planets that show up on the screen when you open this animation are Earth and Mercury. At the top of the screen, students can choose what planets they want to compare. At the bottom of the screen, students can see the dimensions for each planet as well as how they compare in size.
This animation was created before scientists in the International Astronomical Union voted for a new definition of a planet, which effectively removed Pluto from the list. So, Pluto is included in this animation. You may want to alert students to this fact. You also could use this as an opportunity to discuss with your students how scientists reach these kinds of decisions and what constitutes a planet.

Using the Resource
Planet Size Comparison can be used to enhance students’ understanding of our solar system and to help them gain a better appreciation for the sizes of the nine planets, plus the sun and the earth’s moon. This animation would be useful when addressing the Physical Setting benchmarks that focus on the universe. It could also be used when doing lessons on scale, models, systems, or displacing the earth from the center of the universe. When doing a lesson on scale, for instance, this animation could be used to allow students to see the relative sizes of the planets by comparing any planet against another and viewing them at the same scale. So, students not only get a visual image of two planets next to each other, they also can see the diameters of the planets and a ratio in which the diameter of the smaller object is taken to be one unit.

One feature of this animation of which you should be aware is that the size of the planets as they appear on the screen may vary depending on the size of the planets next to them. For instance, even if students keep the Earth in the left-hand screen as they compare it to other planets, its size may change from how large it appears when compared to Mercury versus the sun. This could cause some confusion among students so you may want to make sure that they understand that the size of a plant on the screen may vary simply due to the limitations of the animation itself.
