Paper Electrophoresis

High school physical scientists collide with motion. They work in pairs to design a paper car that will protect a raw egg during a head-on collision. Measurements of distance traveled, time of run, vehicle specs, and photo gate flags are...

Investigate the relationships between different deep-sea organisms by DNA sequencing. A worksheet provides instructions for DNA sequencing and space to work. They simulate gel electrophoresis by cutting out paper "DNA strands." Modeling...

Please turn off the lights to conserve energy. Or not, after all energy is always conserved. This first lesson in an eight-part series includes three parts. Part A contains one hands-on activity and two inquiry-based experiments on heat...

Scientific method, linear measurements, friction, inertia. Imagine learning scientific vocabulary in an ELA class. Before researching and developing a presentation about simple machines, class members build a common, but decidedly...

Students investigate simple machines. In this simple machines lesson, students construct two simple machines and describe what they do. Students show that simple changes help machines do work with less effort. Students use a paper clip...

Pupils name and recognize six types of simple machines. They use their research to design an amusement park ride that features different types of simple machines. Students create a brochure about their ride and how it works. Simple...

Polyatomic ions... where do I begin? One of the most difficult concepts for budding scientists to learn and recognize comes to life in an enlightening resource. Show pupils some demonstrations, via the sixth video in a series of 10, to...

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint")...

Young scholars perform inquiry into the ancient art of Kirigami. The research provides a context for the lesson and how it is related to History. Students also appreciate the art for the sake of its contribution to culture.

Twelfth graders display simple machines through the use of graphics, experiments, and animation. They apply problem solving and design and skills.
