Where is HIV/AIDS most prevalent and what are the current trends regarding HIV? Have groups work together to map the world's HIV/AIDS rates, then create a class map with all the data. Lesson includes cross-disciplinary concepts including...

As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

Although it was published in the year 2000, this chemistry assignment is ideal for practicing the application of Charles' law. There are seven real-world problems to solve, and plenty of space provided for doing so. Add this to your...

Elevate young scientists' skills with unit conversion using the stair-step method. Detailed instructions and a neat stair-step diagram are on the first page. Four pages of practice problems follow, mostly with real-world applications....

Zoe and RJ are trying to photograph an egret on a lake, but they are having trouble with the lighting. Reflection, refraction, and absorption are explored through their thoughtful dialogue so that your physical scientists are illuminated...

In cooperative groups, middle schoolers contemplate the probability of 18 different situations occurring. After they make predictions, they compare them to the actual risk factors. This eye-opening exercise demonstrates that the odds of...

Using a simple circuit with the battery representing the brain, future physiologists test to see which solutions conduct electrical "nerve impulses." Enlighten learners with plentiful information on electric signals in the nervous system...

Ever wonder what the villi in the small intestine do? I bet your class would love to find out. Mesh netting is used to represent small blood vessels on the outside of the intestine, and a chenille bath mat is used to represent the villi...

Glucose is a simple sugar and a molecule that can be illustrated through modeling. Scientific investigators with visual impairments use hands-on models to reconstruct the process of bonding molecules. The tools used in this activity are...

In a friendly, casual conversation on the beach, two animated teens discuss the periodic table. Assign this video to be viewed at home by physical science fans. After viewing, they can write definitions for key vocabulary terms and take...

This video about pH will not leave a sour taste in your mouth! Through clear explanations and a little humor, upcoming chemists will learn the definitions and properties of acids and bases, as well as how pH is measured. This would make...

Compound class members' knowledge of elements and compounds with this delightful video clip! As the animated characters work on baking a birthday cake, they reveal that elements are simple substances that can be combined to form...

Break your class in to the general structure and function of the brain. Brainiacs discuss what they know about it and create personalized brain development timelines. They also take a true-false, pre-assessment quiz to get them thinking...

Your class won't get on your nerves while doing this modeling activity! After teaching the structure and function of a neuron using the included diagrams, give individuals some clay and chenille stems so that they can make their own...

Human body systems students play a card game, "Locks & Keys" in order to learn that neurotransmitters carry a message from one neuron to another by fitting into a receptor site on the receiving nerve cell. While this activity can...

As part of a unit on the chemistry of the brain, thinkers learn how chemicals work to transmit messages between individual neurons and how controlled substances impact the synaptic cleft. They do so by playing a dice-and-card game in...

A lamp, four globes, and some signs taped around the room are all you need to set up a solar system simulation for teaching how Earth's tilted axis creates the seasons. (Sticky dots are also needed, but not mentioned in the materials...

In a math or life science class, "mini-me" models are created with cardstock to reflect a 1:10 scale of young scholars' bodies. Learners measure each others' heights with meter sticks, and then reduce the size by 10. After this exercise,...

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Get your class thinking with animations of neurons in action and explanations of how stimuli is transported and processed. This film makes an ideal introduction or review of the nervous system. The parts of the brain and what they...

How does this sound? It's a rockin' video starring two teenage girls talking about music, hearing, and the ear. Listeners hear that the ear does not only gather sound waves, but also helps us maintain balance. They also will get an...

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....
