### Activity: Cooking with Conversions

In this activity, students will be given a common homemade recipe for German chocolate cake with measurements in English units. They will be asked to convert the English ingredients list to metric units through scientific calculations. Students will also be asked to identify the ingredients as solid, liquid or gas. While reviewing the cooking procedures, students will classify certain steps as containing compounds or mixtures as well as identify whether chemical or physical changes are taking place. The culinary chemistry involved in this lesson should be introduced throughout the activity.

• Density, Identifying an Unknown, Measurements | Elementary School, Middle School

### Demonstration: Household Densities

In this demonstration, students will make predictions about various household materials and whether or not each will sink or float when placed in water. Data will be collected and then used to calculate the density value of each item. Finally students will analyze the relationship between the density value and the observed outcome, and use their knowledge to identify unknown materials.

• Review, Dimensional Analysis, Measurements | Middle School, High School

### Activity: Dimensional Analysis Show Down

In this activity students will work cooperatively to solve conversion based problems using dimensional analysis. Students are required to independently determine an answer for each question and be able explain their method of solving with their peers. This activity is designed to allow students to work at their own pace, and for students to take on a teaching role by communicating their understanding with their peers.

### Activity: Simulation Activity: Measuring Volume

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.
