People associate calories with food, but what is a calorie? Young scientists measure the number of calories in samples of food to better understand the concept. They test a variety of samples, take measurements, and compare their results...

Why do we sweat? Scholars analyze data about body temperature, sweating, and other factors to better understand sweating. They note the changes after drinking ice water to sweating, skin temperature, and body temperature. Analysis...

Young scientists explore hearing through multiple experiments, demonstrations, and activities. They focus on the changes in hearing over a lifetime, how we can determine where a sound is coming from, and the ability to filter noises.

Not all fat is bad—eating good fats actually helps with weight loss. Learn how the body uses fat through a 27-slide presentation that breaks down the path fat takes from entering to exiting the body. Understanding why fat is helpful and...

How do police determine the speed of a car that has hit a stopped vehicle? Scholars determine the momentum of the car system both before and after a collision. They identify instances where the law of conservation of momentum appears to...

Should people take vitamins or get the needed minerals through diet? Experts disagree based on many different factors. Scholars compare study findings and discuss the differences. They learn the importance of comparing results across...

DNA writes 64 different words but only codes for 20 different amino acids. Budding scientists learn about where each of these numbers come from and why they aren't equal with an online interactive. The resource explains the research, the...

One of the first models of DNA appeared to be a triple helix. Young scientists learn about the many scientists who worked to find the shape of DNA. They observe multiple models, tests, and experiments to understand the conclusions. An...

In 1993, Phillip Sharp and Richard Roberts won the Nobel Prize for their discovery of split gene theory. Learn about the breakthrough with the help of an online interactive. Hear both scientists explain it in their own words, watch an...

Have you ever been so tired you missed a major announcement? Eric Wieschaus woke to a call explaining he won the Nobel Prize, but he thought it was just a dream until Christiane Nusslein-Volhard, a co-winner, explained it to him later...

Everything evolved from a common ancestor, but how did modern plants and animals develop so many more genes? Scholars use an online interactive to learn about the process. They begin to understand common genes with an animation, multiple...

Personalized medicine prevents many trial-and-error scenarios when time counts the most. Learn how gene expression and screening genomes improves health outcomes in cancer patients, those with auto-immune disorders, and more. An online...

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...

A day in the life of a wasp queen is not as royal as it may sound. Pupils assume the role of the wasp queen to complete an interactive activity that simulates building a colony. They make decisions along the way and note the changes from...

The term periodic in periodic table has meaning. Young scientists view a video to learn about the periodic table and then use the provided resources to create their own tables. They focus on patterns of the chemical properties of each...

Can organic molecules come from a pre-biotic environment? Stanley Lloyd Miller proved it is possible when exactly the right conditions exist. Learn about his experiment and the other experiments later building off of it that changed the...

Twelfth graders display simple machines through the use of graphics, experiments, and animation. They apply problem solving and design and skills.

Learners use chart data to determine the location of the epicenter of an earthquake. This task assesses students' abilities to generalize and infer, organize data, interpret data, and apply mathematical concepts.

Seventh graders complete a challenge to create a catapult that projects a marble or other projectile at least one meter. While experimenting they apply the Four Question Strategy to answer the question, " How can I make one modification...

Students explore the building of a pyramid and how pulleys were used to change the direction of applied force. They demonstrate the mechanical advantage of using a pulley and apply it to modern engineering.

Learners apply the principles and concepts associated with energy and the transfer of energy in an engineering context through the designing and making of a musical instrument. After the accomplishment of the design, students must...

Students calculate distance, velocity, acceleration and time on their fantasy trip to the black hold. They apply Newton's Laws of Motion and calculate circular motion. They discuss any questions that may arise.

Young scholars are able to analyze gravity as an universal force. They are able to determine how the force of friction retards motion. Students are able to apply Newton's Laws of Motion ot the way the world works.

Learners study concepts of energy and energy transfer. They look at how these concepts apply to musical instruments. They study the law of conservation of energy. They use the concepts studied in the lesson to design a musical instrument.
