Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...

Elsa is a lioness who was raised by humans in the 1950's. The Adamsons took her in after George Adamson reluctantly killed her mother. Elsa did return to the wild but maintained a very strong bond with the Adamsons until her death in...

Students investigate the 1950's pollution tragedy in Minamata, Japan. The elements of dose, response, individual susceptibility, potency, and threshold of toxicology are explored in this lesson.

Students analyze the exploration of space. In this space instructional activity, students discuss the space race of the 1950s and 1960s. Students identify important events in space exploration and analyze the reasons for a space station.

Students investigate numerical data on a possible asthma epidemic. Using statistical information, students graph and figure ratios of the epidemic. They evaluate the mortality rate from severe smog in the 1950's in London.

The Green Education Foundation found that this lesson plan, written by the Texas State Energy Conservation Office, is right up their alley when it comes to teaching sustainability. It is ideal as a first lesson plan on photovoltaic...

Learners investigate magnetic evidence that supports the theory of sea floor spreading.

Learners conduct a simulation to explore how scientists estimate the size of animal populations. They analyze a random sample and then extrapolate those results to a larger population. Additionally, they will apply the principals of...

High school physical scientists collide with motion. They work in pairs to design a paper car that will protect a raw egg during a head-on collision. Measurements of distance traveled, time of run, vehicle specs, and photo gate flags are...

Regulations exist in many places from business to schools, but what about in our genes? Learn about gene regulation with an online interactive. It uses an animation to introduce the topic, many photographs of the scientists best known...

Some people have a natural ability to jump, but did you know DNA also naturally jumps? Learn about the fun habit by looking at the research of a pioneering female scientist. Barbara McClintock fought prejudice and surpassed her mentors...

Roger Kornberg, the oldest son of two biochemists, won the 2006 Nobel Prize in Chemistry. Learn about Kornberg and his scientific research with an animation, videos, biography, and an applied problem-solving activity. A summary and...

Does natural light damage or repair DNA? Learn the answer discover the scientists who researched the topic with an online interactive. Scholars read through an online animation presenting the content at their own pace. Then, they read...

Young scholars review the meanings of global warming and global dimming. While watching a video, they take notes on different aspects of the issue. In groups, they develop a list on what can be done to reduce global dimming. They...

Students explore the concept of triangulation that is used in navigation satellites and global positioning systems designed by engineers. They determine ways these technologies can help people determine their position or the location of...

Learners read and discuss an article on the devastating effects of crystal meth on a fetus development in mice. They relate this research to the possible causes of birth defects in babies whose mothers have used meth during pregnancy.

Students design and conduct an experiment to test three organic pesticides to control ants. They view a video that demonstrates ant behavior and the role of pesticides in insect control. In small groups, they set up behavior...

Students read excerpts from Annie Dillard's memoir, "An American Childhood," with the teacher. They experience opportunities to connect English, science, nature and art together from a new and unique perspective. This approach serves as...

In this craters activity, students solve 3 problems including converting units of Joules into a number equivalent to a one-megaton nuclear bomb, finding the diameters of craters in a given picture and determining the energy needed to...

In this van Allen Radiation Belts worksheet, students are given the formula for the field line of the Earth's inner magnetic field. Students use this equation to find the polar coordinates of a field line in the van Allen Belts. They...

In this elementary particle mass worksheet, learners calculate the mass of elementary particles in kilograms and million electron Volts. Students solve 4 problems finding Top Quark mass, total quark mass of a proton and Strange Quark mass.

Learners create a website. In this technology lesson, students use digital cameras and video to document their field trip to a local fish hatchery. Learners use the photos and videos to create an instructional website.

Young scholars explore the significance of the four space programs: Sputnik, Apollo, Viking, and Voyager. In this space exploration instructional activity, students view a space exploration slideshow and complete an included chart of...
