  Periodic Table, Elements, Percent Composition | Middle School

  Activity: The Universe of Elements Mark as Favorite (15 Favorites)

  In this activity, students are introduced to the periodic table and its elements. Student will discuss that all material in the Universe is composed of elements and that the atom is the smallest particle that still has the physical and chemical properties of any given element. Students will engage in an activity to determine the percent composition of common elements in the universe, and based on their results they will hypothesize the identity of each element based on its relative abundance.

  Density, Measurements | Elementary School, Middle School

  Lab: Weight Just a Minute! Mark as Favorite (2 Favorites)

  In this lab, students will learn how volume and mass affect density as they make comparisons and calculations.

• 

  Concentration, Mixtures, Interdisciplinary, Scientific Method, Measurements | Middle School, High School

  Lab: Effect of Salt Concentration on Plants Mark as Favorite (10 Favorites)

  In this lab, students will observe how salt concentration can affect the structure of a potato tuber.

  Significant Figures, Measurements, Accuracy, Density, Accuracy, Error Analysis, Error Analysis | Middle School, High School

  Lab: Significant Figures and Lab Data Mark as Favorite (98 Favorites)

  In this lesson, students will use laboratory equipment of different precision to collect data for several different metals, and then use the data to calculate the density of each. They will then compare their calculated densities to accepted values and determine the combination of equipment that leads to the most accurate calculation of density.

• 

  Temperature, History, Accuracy, Physical Properties | Elementary School, Middle School, High School

  Video: The Temperature Guys Video Mark as Favorite (80 Favorites)

  This video tells the story of how temperature as we currently know it evolved. The first thermometers invented in the early 1600s are very different than ones we use today!

  Conservation of Mass, History, Observations, Measurements, SI Units | Elementary School, Middle School, High School

  Video: Antoine Lavoisier Video Mark as Favorite (18 Favorites)

  This video tells the story of Antoine Lavoisier who many consider to be the father or modern chemistry. Lavoisier discovered oxygen and hydrogen and first proposed the Law of Conservation of Mass.

• 

  Dimensional Analysis | High School, Middle School

  Activity: Unit Conversion Online Tutorial Mark as Favorite (59 Favorites)

  In this activity, students will interact with a web-based tutorial that uses a drag and drop interface in order to learn how to convert between units of measurement using dimensional analysis. The tutorial allows students to learn at their own pace, and also provides feedback while they are solving problems.

• 

  Concentration, Solute & Solvent, Mixtures, Solubility, Percent Composition | Middle School

  Lab: The Perfect Kool-Aid Concentration Mark as Favorite (11 Favorites)
