This kit is a unique teaching tool for introducing your students to the fascinating chemistry and physics behind invisible inks, i.e. colorless substances usable for writing that can be made to turn to color using a chemical or physical process. Students investigate how organic fluids and chemical reagents can be used as invisible inks. Relying on historical example, students create various invisible inks (and security) documents for other student groups to analyze and decode! Includes materials for two detailed activities (each with a ‘model’ and ‘inquiry’ investigation paths – a total of four investigational activities), which can accommodate up to 40 students. Also contains a DVD with PDF Teacher and Student Guides and other digital content (see below). Covered concepts include: data analysis, chemical & physical processes, elements, mixtures & compounds, pH indicators, transmitted vs. reflected light, the periodic table, fluorescent compounds, types of chemical reactions, and hypothesis testing.
United's series of STEM based curriculum kits accent the scientific method and independent inquiry featuring hands-on learning materials and exciting interactive digital content that can be accessed on a computer, tablet or your mobile device. Kits contain structured, guided, and open investigations, at introductory, intermediate, and advanced levels, to make inquiry based learning affordable and fun. Requires additional household materials for independent investigations.
For pennies per experiment, your students have access to digital PDF content such as:
- Independent Investigation Inquiry suggestions
- Background information including content tables and concept animations
- Powerpoint concept presentation (and video version)
- Comprehensive Glossary
Student activity PDFs have a special Typewriter functionality allowing them to take notes, record experimental data, and answer analysis questions. They simply e-mail their worksheets back to you!
