Introduction Egeria densa, also known as Elodea densa because of its previously incorrect classification in the Elodea genus, is the most popular aquatic plant
For chemistry teacher Siobhan Julian, teaching the history of atomic theory by lecture “was dry and tedious and boring for everyone involved.†Then she took a fresh approach—one that focuses on doing science to learn science history.
Introduction This laboratory activity explores the topics of stoichiometry and limiting reactants in a fun, delicious way! Mass/mole relationships and
Lead students in an engaging and creative project where they build a model that demonstrates the flexing action of the
Ballistics is the study of projectile motion and a critical area of investigation in forensic study. When a projectile is
Students perform forensic hair analysis to learn how hair structure aids crime investigations. They compare samples under a microscope, identify features like medulla and cuticle, and explore the limits of hair evidence without DNA.
Blood evidence can be analyzed as either biological or physical evidence, making it a powerful specimen for teaching forensics across
Students use silver nitrate to develop latent fingerprints, learning the chemistry behind the reaction with chloride ions in sweat. This hands-on forensic activity demonstrates how prints become visible and explores real-world crime scene applications.
Ultraviolet-sensitive beads change color when exposed to ultraviolet (UV) light. Students can use these beads to perform inquiry-based experiments to
Investigate physical science and engineering concepts including buoyancy, displacement, and density. Students construct an aluminum foil boat prototype and measure how much weight their boat can carry before taking on water or sinking.
In this activity, students use a solar-powered model, such as the dancing flowers often sold at discount variety stores. They carefully disassemble the plastic housing and attach a sensor to the capacitor, then use probe ware to graph the voltage across the capacitor.
The Connection Between Taste, Smell, and Flavor The sense of taste and smell are closely related. Humans can distinguish 5
Budgets and all the administrative work around them are always top frustrations and stressors for lab managers and college or
Introduction Growing snowflakes in a bottle can be a fun demonstration to show your students, or they can grow their
Dry ice is added to a basic solution of dish detergent and universal indicator. Commercially, dry ice is used as
Sculpting the musculature of the lower leg Human anatomy is often taught using a systems approach–skeletal system, nervous system, digestive
This lab activity will guarantee a snow day! Teach solutions and crystallization while making snowflake decorations for your classroom. Looking
