Rates per unit of time, unit rates, and the distance and lengths of trips are solved in this 18-question assignment. Neatly presented, these questions provide your middle school mathematicians practice with unit rate skills.

The instructions for this exercise say learners should connect words on an 8x7 grid (which doesn't fit neatly on a single sheet) using vertical and horizontal lines. I think the words could be cut out and moved around on a desk or table...

At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the...

Before completing this worksheet, chemists are supposed read a portion of their textbook. Assign the chapter on bond energies, endothermic, and exothermic reactions. Then have your class answer the questions and fill in the data tables...

Your chemistry class set up six different redox reactions in the lab. Inquisitors methodically test each one and eventually order them according to oxidizing strength. This is a neat way to have the learners perform more than one...

Neatly organized and easy to read, this chart summarizes five different molecular shapes: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. It associates shapes with electron pairs and atom arrangement and lists...

Tomorrow's engineers visit an intriguing website about inventions that have changed the way we live. Biographies of child inventors on the suggested website aren't easy to find, so make sure to find some stories to share in place of...

A neat handout immerses learners in the history of canoe making. After reading, small groups of mini engineers work to craft a canoe that will not be immersed! This is an ideal exercise in engineering design for your STEM curriculum or...

Five acidic and five basic solutions are listed for your chemistry apprentices to review. For each, they must state which atom or ion is being oxidized or reduced, and then name the oxidizing or reducing agent. Finally, they balance each...

Upper elementary or middle school scientists determine what types of energy are involved in six different pictures. Then they produce examples of three different energy transformations. This activity has colorful graphics and is neatly...

A neat presentation and challenging content make this solutions worksheet an ideal homework assignment for your budding chemists. Short answer and problem solving questions get them to review molarity, products, and reactants.

What factors drive a coastal ecosystem? Marine biology or environmental studies classes find out by viewing this presentation. They meet the fauna and flora of salt marshes and mangroves. They are familiarized with threats to these...

The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...
