In this molarity instructional activity, students determine the concentration or molarity for each of the solutions. Students manipulate the molarity formula to calculate the moles, mass, or volume of each problem.

Explore ethanol and how it is produced. Young scientists investigate photosynthesis and fermentation to the concept of conservation of energy and mass. They discuss the environmental and economical benefits of ethanol as a fuel additive.

After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

By playing games to review information, your class will be able to recap their unit of study, and also clarify any snippets of information they may not have remembered.  This jeopardy game covers the main categories regarding...

Examples and practice questions will help real-life understanding of the Principle of Moments concept. These great slides define the types of levers and pivots, and then give examples of the typical seesaw situations that help the...

Send physics learners into orbit by assigning this seven-problem worksheet. They will calculate the mass of a satellite, construct a force diagram, determine the radius of the orbit, and more. Physics worksheets can become wearisome, but...

Young chemists get a handle on the behavior of gases when viewing this presentation. It incorporates thorough explanations of the ideal gas law, molar mass, empirical formulas, and partial pressures. A highlight is the learning check...

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

A 10-lesson unit takes young historians through a study of The Great Depression and life in the 1930s. The crash of the stock market, the Dust Bowl, unemployment, and mass migration west are all addressed through the analysis of primary...

Here is a fantastic reading passage and discussion question to challenge your advanced learners. They read a passage describing arguments against the mass production of tomatoes for fast food resulting in poor treatment of workers. Then...

The Columbia Exchange was one of the first major instances of mass international trade. Learners cut out 24 images of trade commodities and glue them on a map of the world. It'll be fun for kids to see where so many products they use...

Guide first-time physical science learners through the periodic table of elements by having them record the atomic number, atomic mass, number of electrons, number of protons, number of neutrons, or the name of an element when given it's...

What better way to learn about muscle than by dissecting one? Using cow muscle (beef), learners compare bundles of yarn to muscle fibers as they explore each. The supplemental reading about astronauts losing muscle mass in space and what...

Being an astronaut takes not only high mental acuity, but also a high level of physical fitness, especially for those who spend a long amount of time away from Earth, such as the astronauts serving on the International Space Station....

Compare the volume of an orange to the volume of liquid that can be extracted out of it. Also compare the mass of an apple before and after it has been dried out. In both of these activities, children find that there is an appreciable...

Inflate this unit on the science of air with these math skills practice and word problems. Accompanying the children's story Mr. Slaptail's Secret, this resource covers a wide range of math topics including the four basic...

Colored boxes with white font present the basic periodic table of elements to your young chemists. All of the basics are included: chemical name, symbol, atomic number, atomic mass, and the number of electrons in each orbital. A brief...

Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...

As the Summer Olympics are approaching, incorporate Olympic-type games into the classroom. From straw javelin to cotton ball shot put, these games are sure to keep leaners engaged. The best part is that there is math involved! Pupils...

Why was Sir Newton so important to the field of science? Pupils discuss his contributions, specifically his Third Law, as they learn about gravity and the center of mass. They work multiple problems to ensure their understanding and...

How do you properly illustrate the extreme size difference between two planets—Earth and Jupiter? With the help of jellybeans, of course! Create a scale model of Jupiter's mass compared to Earth using a fishbowl, 1,400 beans, and a...

Stimulate interest in ocean currents with a simulation. The first installment of a five-part middle school series teaches future oceanographers about the forces that interact to cause ocean currents. A simulation shows how wind and...

Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank...

Carbon is the fourth most abundant element in the universe (in terms of mass), behind hydrogen, helium, and oxygen. Scholars learn about the carbon cycle, from ways carbon is removed from the atmosphere to how it is added in...
