Sharing ideas and inspiration for engagement, inclusion, and excellence in STEM
Vernier offers more than 1,000 experiments in biology, chemistry, engineering/robotics, and physics that can promote STEM literacy and help you integrate data-collection technology into your courses.
- Use a spectrophotometer to measure color changes in DPIP due to photosynthesis by chloroplasts.
- Use reference sources to find out more about photosynthesis by chloroplasts before choosing and investigating a researchable question. Some topics to consider are listed below:
- electron transport chain
This experiment aligns with the theme of National Chemistry Week 2022—“Fabulous Fibers: The Chemistry of Fabrics”—and it is a great choice for hands-on chemistry learning all year.
To conduct this experiment, students use a spectrophotometer. The objectives of the experiment include
- Synthesize methyl orange from the reaction of a primary amine with nitrous acid.
- Calculate product purity using a spectrophotometer.
- Observe the spectroscopic changes of methyl orange under acidic and basic conditions.
- Explore how organic chemistry is an essential component of the textile industry.
This experiment can be conducted with several different sensors:
- Go Direct Acceleration Sensor
- Go Direct Force and Acceleration Sensor
- Low-g Accelerometer and a LabQuest® interface
The objectives of the experiment include
- Measure centripetal acceleration on a record turntable.
- Determine the relationship among centripetal acceleration, radius, and angular velocity.
- Determine the direction of centripetal acceleration.
