Extraction of Allicin: The Active Ingredient in Garlic

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided instructional activity to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create...

Seeing is believing! Bring DNA to life for young biologists using a simple extraction lab. Individuals extract the DNA from wheat germ, then place it in a microcentrifuge tube for observation. They thread yarn or other material through...

Two guard cells protect every stoma on a leaf. The video explains the structures of leaves, including stomatas. It details how to identify the parts under a microscope.

Students explore atomic structure. They observe a video on atomic structure and complete a Venn diagram on the parts of the atom. Students create their own graphic organizer on the parts of the atom using Inspiration software.

What may look like a bunch of dots is actually complex science! Gilbert Lewis' work is important for understanding molecular chemistry, and his approach is great for visual learners. The video describes the process of drawing a Lewis dot...

Changing the number of neutrons in an atom makes it an isotope, but it does not change the element. Pupils complete logic puzzles, matching isotopes with their unique number of protons, neutrons, and electrons. Either on paper or timed...

The Next Generation Science Standards list Structure and Function as the sixth concept that applies to every type of science. The video explains the relationship between structure and function. To finish, it offers the progression of...

Help young botanists get to the root of photosynthesis with this series of worksheets. By completing these diagrams, students demonstrate their understanding of the biological structures and chemical reactions that make this amazing...
