Activity 3.2 - Observing Soda Water Fizzing (30 min)
Target Student Performance
Students record data about changes in mass and BTB when soda water fizzes and reach consensus about patterns in their data.
Resources You Provide
- BTB, blue (less than 1 cup per group of four students)
- digital balance (1 per group of four students)
- Petri dish, plastic (2 per group of four students)
- sealable, 9.5-Cup container (1 per group of four students)
- soda water (less than 1 cup per group of four students)
- (Optional) Molecular modeling kits
- (From previous activity) 3.1 Predictions and Planning Tool for Soda Water Fizzing
- 3.2 Soda Water Fizzing Class Results 11 x 17 Poster (or spreadsheet)(1 per class)
- 3.2 Observing Soda Water Fizzing Worksheet (1 per student)
- 3.2 Assessing the Observing Soda Water Fizzing Worksheet (1 per group)
- 3.2 Observing Soda Water PPT (1 per class)
- BTB Information and Instructions Handout
- (Optional) BTB Color Handout (1 per group)
Prepare the BTB (see instructions in the BTB Information and Instructions Handout), Petri dishes, soda water, digital balances, plastic containers, and safety glasses for students to retrieve for their groups. If you plan to use the poster to record student data, print one copy of the poster before class and post it on the wall. Print one copy of 3.2 Observing Soda Water Fizzing Worksheet for each pair of students. Prepare a computer with an overhead projector to display the PPT. Optionally, print one copy of the BTB Color Handout for each group.
Use the class discussion to interpret how successful your students are at identifying patterns in the class data. Use the 3.2 Assessing the Observing Soda Water Fizzing Worksheet to determine if your students had any trouble with data collection.
