Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Young Einsteins experiment with the acceleration of Hot Wheels™ toy cars down inclined planes at various angles. This classic physics lab activity is thoroughly explained in both a teacher’s guide and a student lab sheet. Science...

Leaf structure and its specializations for photo-respiration are detailed here.  Slides provide information about Photo-respiration biochemistry and its impact.  A class learning about classic respiration will appreciate the...

Upcoming chemists construct atom or molecule models out of candy. This is a classic idea that learners really enjoy; however, this lesson plan is vague. There is no instruction about the structure of atoms or molecules. Make sure you...

Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images...

If you need a summary of all aspects of Mendelian genetics then this  slideshow is for you. The information included is essential for complete understanding of crosses, genotypes, phenotypes, and heredity.

The various experiments and processes that were completed in the 20th century to further our understanding of DNA are summarized here. There are wonderful slides to popularize the scientists who dedicated their professional life to...

Study, manipulate, and research genetic traits. Discuss how genetic traits are passed from one generation to another. Classmates explore how they look like their parents and debate whether or not they can do anything about it? They...

By the end of this section, you will be able to describe the definition, aims, and branches of physics; describe and distinguish classical physics from modern physics and describe the importance of relativity, quantum mechanics, and...

A high school physics lab on classical mechanics in which students study force versus time and acceleration versus time. Students need access to an elevator to complete the experiments. A lab handout is provided.

A six-lesson e-textbook covering topics in one dimension kinematics. Lessons include informational text, interactive activities, and quick, interactive comprehension checks along the way.
