1 – 5 of 5 Classroom Resources

• Dimensional Analysis, Measurements | High School, Middle School

### Animation: Measurement

In this animation, students will become familiar with three forms of measurement, including length, mass and volume. Various units of measurement will be presented for comparison, and several conversion calculations will be demonstrated using dimensional analysis.

• Observations, Physical Properties, Chemical Change, Physical Change, Dimensional Analysis, Measurements, Matter, Mixture, Chemical Properties | High School, Middle School

### Activity: Cupcake Conversions, Bench to Bakery

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.

• Physical Change, Dimensional Analysis, Measurements, Matter, Mixture | High School, Middle School

### 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.

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

• Dimensional Analysis | Middle School, High School

### Activity: Unit Conversion Online Tutorial

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.
