Yeast and sugar go beyond the pantry and into a fuel experiment. Use these common baking ingredients to assist your class in creating ethanol, a natural fuel. Pupils observe the process and gather information to elaborate...

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...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Third graders are challenged to draw their own rectangles given a specific area or perimeter. There are no examples of how each rectangle should look, so it is important for learners to persevere in finding a solution. There is more...

Get your classes moving and practicing sequences at the same time! Learners move about the room solving problems and finding their solutions. Problems include both recursive and explicit formulas and both geometric and arithmetic sequences.

Show high schoolers there is more to quadratic functions than just formulas and parabolas. Connect the math to realistic application problems with a resource that has learners consider such situations as a ball hit in the air, the...

Should every school have solar panels? The 19th instructional activity in a series of 21 has scholars research the feasibility of using solar panels at their school. They begin by gathering data on the solar energy in the area before...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

Brainstorming—the art of coming up with endless ideas. Pupils brainstorm how to solve local problems in their counties and eventually narrow their ideas down to one solution as a team.

Is light related to insulation? An informative hands-on STEM activity demonstrates how light affects temperature. First, the class investigates how light passes through different mediums and how that relates to temperature. Then,...

How can people use simple machines to solve real-world STEM problems? Learn about simple machines using a hands-on, project-based learning activity. First, pupils investigate and evaluate simple machines. Then, they receive a task that...

Continue to differentiate the rest of the trigonometric functions. Pupils see the derivatives of the other four trigonometric functions and begin to memorize the rules. Learners see examples that show that the calculus portion of a...

Given a string of numbers and math symbols, learners take the challenge to insert parenthesis in the proper places to reach certain solutions. This is a challenge, indeed, an engaging enrichment for those who need a little more math!

An educational activity allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

This is an effective simulation of how communicable diseases such as AIDS can be spread throughout a population. Classmates exchange samples from their individual cups of liquid: one of them containing a dilute NaOH solution, and the...

The vocabulary for working with variable is expressions is listed at the top of this handout. Prealgebra pros evaluate four expressions when a value is assigned to the variables. Then an explanation is given about how changing the value...

A solution will work one way or another: find solutions, or use solutions to find the function. Learners use polynomial identities to factor polynomials with complex solutions. They then use solutions and the Zero Product Property to...

A straight-forward exercise awaits your chemistry charges. Two pages provide plenty of room for them to calculate the pH of five solutions, determine the number of hydrogen and hydroxide ions, and solve problems dealing with solutions....

Starting with definitions and terms related to how electricity flows, these slides assist in understanding of displacement reactions. Some typical displacement reactions that occur with a flow of electricity through a solution are...

In this molality and colligative properties worksheet, students determine the molality of solutions and they calculate freezing point depressions and boiling point elevations of solutions.

Emerging chemists find their calling as they calculate the concentration of hydronium and hydroxide ions and the pH and pOH for several solutions. In some cases, values are given, and in others, actual word problems are written out....

Here is a resource where algebra learners show their understanding of a system of equations involving a circle and a line. Once graphed, learners see two points of intersection, one where the ordered pair is read, and a second where...

It's time to show off what they learned! The final lesson in the series is a review learning exercise on the topics learned throughout the unit. Scholars solve systems of equations using graphic and algebraic methods, solve system-based...
