Cyanide, a coordination compound, is used in the extraction of gold and silver. Part 24 in the series of 36 delves into the world of coordination compounds. Classes learn, through readings, discussions, and answering questions, how to...

The color of the sky depends on the time of day. Young scholars experiment with scattering different wavelengths of light to recreate the color of the sky. They observe both the longer blue wavelengths and the shorter red and orange...

It's all about the scale—they're not just wires, they're nanowires! The second instructional activity of the series builds on the oxidation-reduction experiment in the first instructional activity. Scholars synthesize a sample of...

Electromagnets come in both large and small scales—from big machinery in scrap yards to hard disk drives. Here's a resource that provides directions for building a variable electromagnet on a stand. Scholars then experiment with the...

What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Bacteria get more resistant to antibiotics every year. Learn the reason for this pattern and how scientists are addressing the problem in a six-week unit. Learners analyze different types of bacteria and their adaptations.

Star light, star bright ... just how long can you wish on that star? Well, it depends on its mass. The presentation explains the life cycle of stars based on their sizes. Scholars learn about the life expectancy of a star based on the...

Are you looking for a good, solid instructional activity on sedimentary rocks? This one, produced by the Illinois State Museum, is just such a instructional activity. Middle schoolers identify common rocks and minerals by analyzing...

Students are introduced to Sea Floor Spreading and how it provides evidence for Hess's and Deitz's theory of Continental Drift. They use paleomagnetic data to calculate the rate of Sea Floor Spreading.

Does the angle of a solar panel change the output? Emerging engineers find out! Demonstrate for your class how they can angle a straw to match the angle of light rays coming from a source. Then turn them loose to experiment with the...

On this physics handout, pupils read about the Hadron Collider used to make new sub-atomic particles by accelerating protons. They solve 6 math problems that include translating electron volts to Joules. This is geared toward high school...

The concise slides in this presentation give a good amount of detail for many aspects of matter chemistry.  There are summaries and diagrams for particle movement in solids, liquids, gases and plasma.

This wonderful recap of powerful figures in scientific history includes pictures, important dates, and the information about their inventions or impact. Atomic structure and the photoelectric effect are introduced. The first slide gives...

Physics fanatics will shriek over this monster-themed construction application! They design an invention with the intention of competing one of 50 missions and test it out with real physics applications. 

I think I lost an electron. Are you sure? Yes, I'm positive! Starting with a hands-on demonstration and problem solving activity, young scientists define vocabulary related to circuitry and currents. Then they build their own circuits...

Taxonomy is the study of organisms and how you phylum. Three biology activities are included, helping scholars understand four of the six kingdoms, specifically Protista, Plantae, Fungi, and Animalia. Scholars observe and classify...

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

Students read The Wheels on the Bus by Maryann Kovalski. They complete a variety of cross-curricular activities surrounding the study of travel and transportation. Included are reading, art, math, science, writing, social studies, and...

Students isolate three species of bacteria using the plate streak method, implement sterile microbiology techniques, and produce pure cultures of each microorganism at the end of this exercise. They write a descriptive paragraph for each...

In this space science vocabulary worksheet, students read the definitions for 6 common terms. Students then look up 4 words and write the meanings. Students alphabetize the vocabulary words on another piece of paper.

High schoolers observe crystals under the microscope. In this science lesson, students compare how the crystal look like using their eyes, hand lens and microscope. They identify the type of crystal based on the amount of light they...

In this layer of the earth worksheet, students label and color each layer of the earth. Then students are asked to describe each layer below.

In this instructional activity on the life cycle of the butterfly, students look at 4 pictures representing the life cycle stages, and choose words from a word box that match each picture. Students then number the pictures in the correct...
