Student Set – Acids, Bases, Salts – Digital Set – 31 Experiments
$0.00
ABOUT THIS PRODUCT:
Function and Applications
Equipment set allowing the performance of 31 experiments about the following topics:
- Acids (16 experiments)
- Alkalis (8 experiments)
- Salts (7 experiments)
In 6 experiments you can use the Cobra SMARTsense sensors Temperature and pH instead of the classic measuring device in combination with tablets (iOS and Android) and smartphones (Android).
Benefits
- The ideal combination of classic experiments (practical competence) and digital data acquisition (media competence)
- Individual teaching structure possible: you can decide to choose the measuring instrument you want (classic or digital)
- Future-proof: preparing today the transition to the digital school
- Perfectly matched to digital science lessons with tablets and smartphones
- Faster and higher learning success: The use of digital devices increases the identification and thus increases the motivation of the student’s Complete equipment set simple execution of the experiments
- The equipment is stored in a rugged, stackable and compact box, allowing quick control of completeness (foam insert)
- Experimenting literature for pupils and teachers available: minimal preparation time
- Matched with international Curriculum: all topics are covered
- Set developed by pedagogues for introduction into inorganic chemistry
Equipment and technical data
- The equipment set consists of all necessary components for the experiments; only one for the existing gas supply suitable burner must be purchased separately
- Robust, stackable storage box with a foam insert fitting to the contained equipment
- Cobra SMARTsense Temperature: Measuring range: -40 … 120 ° C, resolution: 0.01 ° C, sampling rate: 10 Hz
- Cobra SMARTsense pH: Measuring range: 0 … 14, resolution: 0.01, sampling rate: 10 Hz
