Physics learners experiment with three laboratory activities to learn about air resistance and friction. First, they use a hair dryer to move different sized spheres to determine the relationship between cross-sectional area and air...

Four activities immerse beginning chemists into the world of elements. They examine the periodic table, use cobalt hydroxide to learn about chemical formulae and valence electrons. Also, they name binary compounds and examine the...

Junior geneticists construct models of DNA to discover sequencing and pairing of nucleotides. They use the models to simulate protein synthesis and then translate the codes into physical traits. Finally, they use the traits to create a...

If I want to build up my heart, where should I start? Science scholars use statistics in a sports physiology setting during an insightful experiment. Groups measure resting and active heart rates and develop a scatter plot that shows the...

Four fabulous activities immerse amateur astronomers into measuring objects that we cannot handle. The experiences are applied to NASA's Space Interferometry Mission, which will take measurements of planets around stars other than our...

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

Junior geologists work through three mini-lessons that familiarize them with the formation and location of fossil fuels. Part one involves reading about petroleum and where it comes from via a thorough set of handouts. A lab activity...

Does it cost more per year to heat Bill's home in North Dakota or to cool Bubba's home in Georgia? Using heat transfer concepts, mathematical equations, and critical thinking skills, young engineers work in groups to determine who is...

Physical or earth scientists construct this clever contraption to demonstrate how size effects frequency. Several paper rings of various sizes are taped onto a board and shaken to create vibrations. The resonant frequencies are easily...
