  Activity: Cupcake Conversions, Bench to Bakery Mark as Favorite (10 Favorites)

  This activity will help to reinforce the importance of scientific measurement and apply it to the introduction of chemical reactions. Using an example of baking a single batch of cupcakes, students will plan for a larger production scale in a commercial bakery. This will help to introduce the idea of producing a reaction at the lab bench and converting it to mass production. In addition this activity investigates how chemistry is used in everyday life and challenges students to consider potentials errors that may occur when completing chemical reactions in the kitchen.

  Conservation of Mass, Measurements | Middle School, High School

  Lab: Mass of a Gas Mark as Favorite (9 Favorites)

  In this lab, students will perform a simple chemical reaction in a closed system to produce a small amount of gas. They will collect mass measurements for the reactants and the products in order to demonstrate the conservation of mass during the reaction. They will also release the produced gas from the closed system in order to verify that gasses have mass.

• 

  Density, Observations, Measurements | Middle School, High School

  Lab: Penny Boats Mark as Favorite (8 Favorites)

  In this lab, students will explore Archimedes’ Principle and how it relates to density. Each student will be given a piece of aluminum foil and asked to design and build a boat that will hold as many pennies as possible without sinking when placed in water.

• 

  Measurements, Accuracy, SI Units, Significant Figures | Middle School, High School

  Activity: Simulation Activity: Measuring Volume Mark as Favorite (34 Favorites)

  In this simulation, students will participate in a 10 question quiz. The quiz questions are each made of two parts, with the first part requiring the student to analyze an image of a graduated cylinder in order to report an accurate measurement. Students must use the correct number of digits based on the markings presented on the cylinder when reporting the measurement. In the second portion of the question the students will determine the uncertainty value of the graduated cylinder, again by analyzing its markings. The simulation is made up of several different sizes of graduated cylinders, each containing unique markings, so students will be challenged to analyze each individually.

• 

  Periodic Table, Elements, Percent Composition | Middle School

  Activity: The Universe of Elements Mark as Favorite (6 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.
