Life from Non-Life? A Quantitative Determination

Students interpret a message sent to space using a radio telescope and draw inferences from the interpreted message. Working with a partner, they interpret data that scientists believe is a message from aliens. They work on organizing...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Students receive bloodstain pattern evidence from a crime scene. They answer a series of questions through inquiry, observation, measurement, and analysis. Pupils complete this challenge, by reconstructing the evidence through four...

What can we learn from the data? Young scholars analyze actual solar data to answer specific questions. The activity presents an opportunity for an open-ended investigation of the data to conclude a five-part series on solar winds.

No one wants to be average, so mathematicians use the term mean instead of average. The video explains how to calculate the mean, how to calculate the percent error, and why this information is important. Finally, the video considers the...

Life existed on Earth more than four billion years ago, much earlier than scientists predicted. Eons presents a lively video as part of a larger series. It explains the recent findings on multiple continents that alter the timeline of...

Information is provided on Gray's Reef, Florida Keys, and Flower Garden Banks marine sanctuaries. Young marine biologists then visit the FishBase and REEF databases to collect fish species information for each location. They then...

Making observations and collecting qualitative and quantitative data is a vital skill all scientists need to practice. Help your scientists with partial and no sight learn how to use their other senses to make observations for...

When you think of secret messages and data storage, DNA doesn't normally come to mind. Viewers watch a video that explains how scientists use DNA to store information. It describes some recent advances in the area.

The topic is fascinating, but there is not much for learners to do here. Food borne illness has always been a problem for humans to face, and here, data from the Center for Disease Control is analyzed. Learners look at the number of...
