Don't lose your marbles — you'll need them for a instructional activity on neurotransmission. Young scholars build a neurotransmission model using marbles, beads, rubber bands, string, and other elements. After studying specific...

What does stretching a balloon have to do with equilibrium? Groups explore preconditioning by stretching a balloon to a point of equilibrium. They then measure the amount of force required to stretch the balloon to the same point several...

Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value...

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

Use simple machines to escape from a tree house. Pupils learn about simple machines and how they are useful in everyday life in a STEM lesson. Groups then design a device to rescue a friend stuck in a tree house.

It might be silly to determine the creep rate of putty but groups will enjoy making different formulations of silly putty and playing with them to understand how the different mixtures behave. The second part of the activity has groups...

Get the ball rolling and challenge your class to figure out how to make a ball move. The instruction segment is between two STEM activities devoted to doing just that. The first is simple and involves making a ball move from some...

Show us your moves. Using sensor equipment, scholars track the motion of different movements, such as jogging, skipping, or jump roping. They analyze velocity and acceleration and create graphs representing each movement.

Will that structure survive the force? The differentiated lesson allows pairs to choose the structure they would like to construct and the building materials they wish to use. Individuals record their findings in...

Convey your interest in conveyor belts. By considering different size tubes, groups create a conveyor belt that can transport boxes of candy at least four feet. Also, the conveyor belt must make a 90-degree turn—quite a difficult task!

Learners apply the principles and concepts associated with energy and the transfer of energy in an engineering context through the designing and making of a musical instrument. After the accomplishment of the design, students must...

In this genetic worksheet, students will match 6 terms associated with gene engineering to their correct definition. Then students will complete a table indicating if the vector is mechanical or biological. Finally, students will...

Middle schoolers work on problems in which they investigate conduction, convection, and radiation. They attempt to maintain the warmth in one can of soda while cooling the other as much as possible in a thirty minute period. They examine...

Students examine renewable energy sources such as solar, water, and wind. They experiment to determine how renewable energy is transformed into electricity. They investigate the role of engineers who work in the field of renewable energy.

Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. In seeing how falling water can...

Students determine what the pulse is before examining how to measure the heart rate in different situations. They build a simple device that measures the heart rate, take heart rates, and record them on a worksheet. They discuss how...

Students observe a model of a waterwheel to investigate the transformations of energy involved in turning the blades of a hydro-turbine into work. They work as engineers to create a model for a new waterwheel while considering resources,...

Students investigate horsepower as a unit of power. They examine history and discover that scientists and engineers of high achievement are considered to be among the most valued contributors to their culture.

Young scholars examine the relationship between energy and the environment. In groups, they participate in experiments to discover the law of thermodynamics and the differences between potential, kinetic and mechanical forms of energy. ...

Students research the mechanics of liquid chromatography. In this technology lesson, students calculate the concentration of unknown samples. They write a report about their research and lab results.

In pairs, learners build a piezoelectric generator from readily available electric components in the second and final installment of the two-part series. Tapping the piezoelectric element produces enough electricity to light an LED....

Glide into the study of flight. An engaging lesson has scholars research information on the Wright brothers. They develop props and produce a recreation of the first flight at Kitty Hawk. They then report on the event as if they were...

Students create a model of centrifugal compressor wheel following step-by-step instructions. In this technology activity, students use SolidWorks to create curved surfaces. They give practical applications of a centrifugal compressor.
