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...

Using NASA's Live Access Server, earth scientists compare the temperature, precipitation, and normalized difference vegetation index for four different locations. They use the data to identify the climate zone of each location using...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

Students prepare a sample of a commercial hand lotion for analysis by HPLC to determine the percent composition of two common cosmetic preservatives, methylparaben and propylparaben. They perform the analysis and the data is evaluated to...

Groups analyze and interpret their data from previous research in order to develop individualized findings. The teams then use guidelines to help determine what aspects of their research to include on a poster. Class members...

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

Students engage in a field study of birds and how they are in danger harm due to environmental factors. They list different possible causes in a prediction activity. The observations are done while writing up data and connecting it to a...

Fabulous! Your 5th graders should love this project. As an ongoing lesson throughout the year students use temperature probes to record outside temperature and then document their data using spreadsheets. They use their weather data and...

Reading, writing, and rings! A instructional activity from NASA combines space science with authentic reading and writing tasks. Included in this instructional activity are pre-reading activities, four mini informational...

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Don't want to sound corny, but your class will be a-maize-d by an engaging activity! Explore the history of the modern corn plant through a video and Punnett squares. Junior genetics experts get hands-on experience with actual research...

Students participate in a lab activity in which they examine a simple energy transformation system. Students test the rebound of elastomers, produce rebound data, and determine the kinetic energy transformed by the impact of a free...

Less than one percent of the water on Earth is usable in people's homes. As pupils consider this fact, they reflect on their own water usage before designing a survey to collect information on water usage by others. They then analyze...

My name is Bond, Hydrogen Bond. Written for distance scholars working on chemistry at the high school level, the lesson includes eight weeks worth of material divided into six parts: substances you use, mixing it up, your skin, what's...

Arctic sea ice reflects 80 percent of sunlight, striking it back into space; with sea ice melting, the world's oceans become warmer, which furthers global warming. These activities explore how humans are impacting ecosystems around the...

Combine math and science with fun in the sun! Scientists build a solar gnomon using reusable materials to calculate relative air mass. Mathematicians measure the pole's shadow and use the data to solve for relative air mass....

Students explore principles governing diffusion and osmosis. Students perform a dialysis tubing experiment. They obtain core samples of potato in varying concentrations of sugar-water to measure water potential of the potato cells....

Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

How do robots assist ocean explorers in collecting data and images? The final installment in a five-part series has science scholars examine underwater images collected by robots and identify the organisms shown. Groups then calculate...

Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...

Students research abiotic and biotic factors concerning the concept of an ecosystem. Record and analyze data collected. Write a lab report in proper and scientific format with thinking and analytical skills. Work as a cooperative team.

Designed to accompany the 13-minute video The Making of the Fittest: The Birth and Death of Genes, this handout serves as both a viewing guide during the video and an analysis of how the adaptations of the icefish might help treat...

Here is a thorough lesson on safety in the chemistry lab. Chemists review a detailed list of safety rules, draw the layout of the laboratory area to include emergency equipment, identify hazard warnings, and consult the MSDS in order to...
