To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

Did you realize the visible light spectrum is less than three percent of the electromagnetic spectrum? A hands-onlesson includes five activities and experiments for scholars to explore and discover many advanced science concepts. They...

Though the walrus spends roughly one third of its time on land, it eats organisms that live on the bottom of the ocean. The first in a series of five, the instructional activity uses a variety of plant and animal cards to have scholars...

Do you ever give your class the "teacher look"? Without saying a word, they become silent and engaged (hopefully). How do they know what you're thinking? Explore the concept of nonverbal communication and how it relates to our...

Do you want to learn about how you learn? Help pupils become the best learners they can be by teaching them how their brain works. The resources available include videos about brain structure and a study guide full of activities that...

The subject of this life science reading comprehension instructional activity is the excretory system. After examining the provided article, readers respond to a series of questions using evidence found in the text.

These two pages cover the gamut of topics regarding reproduction and DNA replication. Structures, processes, functions, and reasons for them are tested here. The questions are mostly multiple choice, but there are also a few...

The ciculatory system is introduced here by means of clear, labelled diagrams and charts with details. After learning the basics of the heart strucure, a sequence of slides help show the flow the blood as the heart muscle contracts. A...

Bored with frog and earthworm dissections? Had your fill of fetal pigs? Anatomy students will be intrigued by the sheep's brain, and you will be prepared with guiding questions, extension activities, and pictures as they dissect one —...

Energy doesn't come out of nowhere! An engaging lesson has learners investigate energy as it transforms from one type to another. They collect data to prove that energy is not lost as it changes.

This sequence of slides covers each main macromolecule that is involved with human structure and function. The history of nucleotide research and the way that they are formed is summarized, a diagram accompanies the explanation. The main...

Classify living things with a set of worksheets that has pupils sorting and indentifying living and non-living things. Learners use the worksheets as a basis for finding their answers. 

My, what big energy potential you have! Scholars learn about the energy potential of using algae as a biofuel. A PowerPoint presentation first describes the structure of algae and then how researchers use algae as biofuel to produce energy.

Scientists work every day to find solutions to genetic diseases. Scholars learn about the process of gene sequencing, mutations, and the results. They explore genetic diseases and therapies to intervene and help and, through case...

Most pupils know about the flu, HIV, and other viruses, but they don't know what each actually looks like. This interactive shows their relative size, structure, and allows for comparisons. It stresses the similarities and differences...

After being introduced to the genus Straptococcus, biology buffs set up agar plates, esculin slants, and salt broth tubes with different species to test. The level of laboratory skills required to perform this activity makes it most...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

This is your brain on drugs ... literally! Your neuroscientists-in-training examine the evidence of drug use on the human brain and how neurons change their connectivity when altered by drugs. They then work together to create testing...

Don't lose your marbles — you'll need them for a lesson on neurotransmission. Young scholars build a neurotransmission model using marbles, beads, rubber bands, string, and other elements. After studying specific neurotransmitters,...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

The human body is an amazing thing! Explore the body with your high school class as they investigate each system in detail. They learn components of each organ system and disease processes that can negatively affect general health and...

After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...
