Seventh graders investigate the relationship between energy and matter, and measure the mass of various objects. They listen to a teacher-led lecture about potential energy, and in small groups measure the mass of various objects such...

Young scholars study oxidation and define vocabulary pertinent to it.  In this oxidation lesson plan students make predictions and create experiments

In this titration learning exercise, students determine the number of moles of an ion present in given solutions. Students calculate the relative formula mass and the concentrations of ions for solutions. This learning exercise has seven...

Students study vocabulary based on chemistry terms by creating flash cards.  For this scientific vocabulary lesson, students utilize a chemistry word or phrase to create a card which uses the term, describes it in the student's...

Students are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.

Students build and program a Lego Mindstorms Roverbot to travel for a given amount of time. They gather data on time versus distance traveled to determine a calibration constant for their robot, which relates time to distance.

Students examine how physical quantities and laws depend distance, mass and time. They examine the MKS system; meter, kilogram and second, for doing calculations.

Learners investigate Newton's Second Law of Motion as they predict the effect of a payload on the amount of energy needed to lift a rocket vertically. The constraints of the weight of the equipment carried to Mars is compared to the...

Students are assigned to groups, and determine each member's role in the group. They will design an experiment to determine a way to produce the three primary and five secondary colors. Students discuss color and mood. They listen to a...

Students name the factors (concentration, temperature, and a catalyst) which can affect the rate of a chemical reaction. They use their knowledge of particle theory to explain their observations. Pupils comprehend that the...

Learners collect evidence to make inferences about a object hidden inside a sealed box. They think critically and logically to raise questions. Students identify questions that can be answered through investigation. They formulate and...
