Chemistry Case File #21: The Missing Isotope | Chemistry Mystery Activity

Make Isotopes and Average Atomic Mass calculations relevant with this no-prep digital case file! Turn your students into Astrochemists! In "The Missing Isotope," a meteorite has crashed on Earth. Initial scans show it contains Magnesium, but the mass readings are all wrong. Students must analyze the sample's percent abundance to calculate the new average atomic mass and prove the rock's extraterrestrial origin. This activity is the perfect way to move beyond boring worksheets. It gives stud

A complete one-period lesson on static electricity for Grade 9 Science (SNC1W). The 12-slide presentation introduces charging methods (friction, conduction, induction), the electrostatic series, and the Law of Electrostatics through a dark-themed, visually engaging format. The 4-page follow-along worksheet walks students through vocabulary matching, electrostatic series predictions, a charging methods comparison table, and real-world application questions covering lightning formation, fuel truck

DNA Fingerprinting-Gel Electrophoresis "paper lab"!

Absolutely no prep! Just print and go! This activity will teach students why and how gel electrophoresis is used. Students will also analyze a gel or "DNA fingerprint" and help to solve a crime! This is a great product for a Biotech unit if you do not have the equipment to run an actual gel or use as a fun pre-lab! Used by thousands of students!

Chemistry Case File #12: The Great Solution Switch | Chemistry Mystery Activity

Do your students struggle to understand the math behind Molarity and Dilutions? This no-prep digital case file puts those equations into a real-world context that makes sense! Turn your students into Lab Managers! In "The Great Solution Switch," a lab accident has destroyed the critical chemical solutions needed for an experiment. Students must save the day by calculating exactly how to recreate the missing solutions from a concentrated Master Stock. Students will master the Dilution Equat

Students use PhET Sim to explore density in an inquiry based lab. Check out the Sim here:: http://phet.colorado.edu/sims/html/density/latest/density_en.html?fbclid=IwAR09bUeRxx_DckEweccfg2_1DozdustsrS4RJYOtwDkaHwiyJ6RDzLTofPIThis lab first walks students through finding volume through water displacement. Then students explore densities of different materials with the same mass but different volume, same volume but different mass, and then same density but different masses and volumes. Fina

Conservation of Momentum Lab Series using Marbles

This listing features two labs about the conservation of momentum using marbles. I facilitate this activity series on successive days in my eighth-grade physical science class. This lab set aligns with our unit about Newton’s three laws. In the first lab activity, students determine if there is a positive correlation between the number of marbles released down the ruler ramp and the number of stationary marbles ejected upon impact on the bottom, flat portion of the track. In the second lab acti
