Time to rock and roll! Young scientists test their knowledge about rocks found on Earth and what they tell scientists. A 10-question quiz focuses on the different types of rocks, how they are formed, and what they are made of.

Humans have only inhabited Earth for a short part of its existence. An online resource explains how scientists use clues from rocks and fossils to piece together information about Earth prior to humans. The online instruction includes...

Believe it or not, some dinosaurs are not extinct. Discover this and other interesting facts about dinosaurs in a 10-question online quiz. As individuals answer questions, the resource provides them with feedback and additional facts...

A famous fossil of fighting dinosaurs holds as many questions as answers. Scholars first analyze the fossil itself by virtually highlighting the specific bones of the dinosaurs and read about their function and importance. They then test...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

Pupils learn of multiple ways astronomers look for planets outside of the solar system. By completing a hands-on activity, scholars discover that trying to see the planets directly because of the glare from the nearby star is nearly...

Just when is the universe's birthdate? Pupils use previously collected spectra data to find the redshift and radial velocity of supernovas. They then calculate the distance before finally creating a Hubble diagram. Finally, individuals...

Is the sky falling? Learners use a simulator to modify the mass and velocity of asteroids and collect data on how they influence the diameter and depth of the impact crater. They use their results to draw conclusions and make predictions...

Laws of motion apply both in space and on Earth. Young experimenters model object impact on the Earth and moon. They use data to determine the effect mass and velocity have on the resulting craters and how that relates to the energy of...

Can plants grow on the moon? The second lesson in a five-part series has pupils explore the resources available on the moon to determine if plant life is possible. They use lava rocks as their soil and draw conclusions about the...

Horses come in all shapes and sizes, but all belong to the same species. Young scholars explore the different traits and connect the information to genetic modification. The interactive gives them the option to read about 18 different...

Who doesn't want to know more about the mysterious dinosaurs? Learners read about dinosaurs and the process scientists use to continue learning more about the animals in an interview-type format. A paleontologist responds to submitted...

Design a mission over the rainbow. Small groups spend several weeks together determining a mission related to spectroscopy. The teams build spectrographs and analyze the design to determine whether it will carry out the mission. At the...

Transform the classroom with energy. Pupils learn about different types of energy and practice identifying the types in the first lesson of six in a solar versus wind energy unit. The class sees examples of how one type of energy can be...

Get your hands on electricity. Pupils investigate magnetic fields and make the connection to generators in the fourth lesson plan in a series of six lessons on wind versus solar energy. Learners use a small electric motor as a generator...

No conversation about culture is complete without considering climate. Scholars first view videos of climate witnesses who describe the climate in their regions and how climate change affects their daily lives. They then write essays or...

Talking about weather isn't just for making conversation. Young scientists gather evidence from an interactive activity to make connections between daily and seasonal weather. They analyze data from different areas and compare the...

The periodic table has so much more to it than meets the uninformed eye. An inquiry-based lesson plan leads learners through the history of the discovery of several transuranium elements. They then use informational resources to build a...

Star light, star bright ... just how long can you wish on that star? Well, it depends on its mass. The presentation explains the life cycle of stars based on their sizes. Scholars learn about the life expectancy of a star based on the...

Amaze the class with the creative adaptations species employ to trick predators. An online interactive lesson introduces learners to six different species with unique adaptations. Each species highlights a different adaptation and its...

There is a scallop that relies on sight so much that it actually has more than 100 eyes! There are many species that rely heavily on one sense or another. An online interactive resource has youth read about several of these animals. The...

It actually is possible to have too much of a good thing when it comes to climate change. A slide show lesson describes how burning fossil fuels contributes to climate change. Individuals read about the scientific process and the...

What do cats and human DNA have in common? The second instructional activity of a series focuses on the mapping of mammal genomes. Scholars learn about the structure of DNA as they compare the chromosomes of humans and felines.

Examine the sequence of key events in the history of genetics. An engaging lesson asks scholars to sort events to create a timeline of biotechnology milestones. Arranging the events gives learners a perspective on the development of...
