  Solutions, Concentration, Solubility, Molarity, Graphing | High School

  Activity: Concentration and Solubility Mark as Favorite (32 Favorites)

  In this activity, students will use news articles and EPA publications to compare Federal drinking water regulations to the concentrations found in Flint, Michigan. Students are introduced to the unit parts per billion (ppb) and compare it both conceptually and mathematically to molarity. As a group, students use data to compare the solubility of various lead salts and perform solubility calculations.

• 

  Elements, Periodic Table, Review | High School

  Activity: Clueless Crossword Mark as Favorite (22 Favorites)

  In this activity, students will need a pencil and eraser as they are challenged to complete a crossword puzzle without any traditional clues! Instead, students are given a list of element symbols and tasked with determining the element name for each symbol. Then, using the names, they will then attempt to place each one correctly in the puzzle. With only one possible solution, this puzzle can be very tricky!

  Interdisciplinary, Photosynthesis | High School

  Activity: Algae Trivia Mark as Favorite (4 Favorites)

  In this activity, students will participate in a trivia game created in support of the 2023 Chemists Celebrate Earth Week (CCEW) theme, The Curious Chemistry of Amazing Algae. Students will participate individually or as a team to test their knowledge about algae and related chemistry topics.

• 

  Precipitate, Reactions & Stoichiometry, Solubility Rules, Balancing Equations, Chemical Change, Chemical Change | High School, Middle School

  Lab: Predicting Precipitates Mark as Favorite (31 Favorites)

  In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.

• 

  Quantitative Chemistry, Percent Composition, Measurements, Observations | High School

  Lab: Dehydration of Hydrated Salt Mark as Favorite (15 Favorites)

  In this lab, students are introduced to chemical measurement in a hands-on investigation using a heat source and a hydrated compound. Students will determine the percentage water lost, by mass, from a hydrated compound during the heating process. Additionally, students will analyze and interpret their results in a claim, evidence, reasoning format.

• 

  Atomic Structure, Atomic Mass, Electrons, Ions, Subatomic Particles, Density, Periodic Table, Quantitative Chemistry, Dimensional Analysis, Mole Concept | High School

  Activity: A Pound of Numbers Mark as Favorite (28 Favorites)

  In this activity, students will review a series of fundamental chemistry questions and select the answer from two choices provided. Upon completion, the sum of all the correct answers will equal the number of grams in one pound. Students can then use dimensional analysis to determine the number of grams in one pound for comparison.
