Fifth graders perform experiments to determine the identity of an unknown gas sample. In this chemistry lesson, 5th graders fill balloons with air, oxygen, hydrogen, and carbon dioxide. They use mass and reactivity to identify the gases.

Students attempt to design and build the most stable "earthquke resistant" structure. They create model buildings and test them on a shake table to see which design holds up the best.

Students examine the concept of potential energy and see that it is the ability to do work.  In this energy activity students complete several activities on potential energy. 

Fifth graders work in teams of four to measure the rebound heights of a tennis ball dropped from four different heights. They investigate with the bouncing balls to measure changes in the type of energy they possess.

Students collect experimental data and record it on a frequency table. After accessing an Internet coin toss simulation site they discover that repetition of an experiment may result in different outcomes. They identify the mutually...

Students use this introductory lab using a tennis racquet, however it is very difficult to study because of the strings and the racquet stretch so little and so quickly during a match that students were unable to make simple...

Learners discover the science behind a tennis racket by looking at a simple toy that works in a similar way. After looking at the related mathematical equations, students experiment with the simple toy to find the spring constant k by...

Students explore weather instruments. In this weather instructional activity, students make rain gauges, anemometers, and barometers following the instructions given in the instructional activity. Students set up a weather station using...

Introduce middle schoolers to the issue of video game violence with a multifaceted approach. Learners complete a gaming survey, as well as read and discuss a news feature about violent video game sales and a handout on stimulus...

Young scholars discover and identify positive and negative electrical charges and understand that like repels and opposite charges attract.  In this physics lesson, students observe how friction can be used to give electrical charge...

Students explore current events by analyzing a news article in class. For this school ban lesson, students read a story about a high school in London that has banned physical contact between all students. Students answer study questions...

Fourth graders participate in a ball identification exercise to help them identify birds. As a class, their teacher throws them a variety of different sized and colored balls for them to describe. Using these factors, they work together...

Young scholars explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function. Students graph and...

Students experiment with varied balls to determine the bounce factor in centimeters. In this physics lesson, students experiment to find the height a ball must be dropped from the have the highest bounce rate. Students graph the results...

Students investigate the basic principles of air pressure.  In this experimental lesson students use materials to create several different experiments that help to explain air pressure and friction.

Pupils complete a hands on activity to determine how scientists use indirect observations to define problems that are not directly measurable. They complete an associate student handout.

Seventh graders relate patterns with higher math. In this 7th grade math lesson, 7th graders analyze different methods of portraying data. They relate the data to real life scenarios.      

Learners explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.

Learners examine the law of conservation of momentum. In this physics lesson, students play marbles in order to compare the mass of the marble and velocities effects. Learners receive directions of the marbles game and collect data while...

Ninth graders experiment with bouncing balls to investigate the elasticity coefficient of different sizes and types of balls. In this superball physics activity, 9th graders bounce various types of balls from differing heights. They...

Students investigate nutrition by creating ice cream in class. In this cooking lesson, students define the ingredients in ice cream and discuss how they form together to create a delicious treat. Students utilize salt, ice, milk and...

Students discuss the topic of streamflow and how it occurs. They take measurements and analyze them. They interpret data and create their own charts and graphs.

Students make observations of a bouncing ball and study how it travels.  In this height lesson students complete a lab activity and describe and explain the motion of the ball. 

Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.
