In this enzyme worksheet, students solve 6 problems including questions about how enzymes work, graphs of the relationship between enzyme and substrate and structures of enzymes.

In this physical and chemical changes worksheet, students will read 4 different examples of a physical or chemical change and will write in the effect of each of these changes.

Students examine electricity.  In this circuits lesson students complete an activity that shows them the configuration of circuits. 

Students investigate the chemistry of coal. This lesson serves as a review of conservation of mass, simple reactions and equation balancing. During the lesson, students research chemical components of coal, as well as environmental...

Middle schoolers use a two-liter bottle, dowel rod and index cards to design and construct a water wheel. They then calculate the power created and measure the work done by the water wheel in Watts and Joules.

Students participate in a class discussion on site of an older style bridge to help connect the significance of each organism in an ecosystem by using an analogy of bolts slowly being removed from a working bridge.

In this review of physical science learning exercise, students use recall to answer multiple choice questions about electricity and chemical changes. Students answer 25 questions.

Students compare and contrast fossil fuels and bio-fuels. They brainstorm what mining might look like in the future. Students view the film "A Day in the Life of a Coalminer." They discuss fossil fuels and the methods of extraction....

Ninth graders concentrate on arsenic poisoning as an example of the connections among health, geography, and geology as they develop a persuasive presentation about the dangers of arsenic in the drinking water, targeting a specific...

Student is introduced to the concept of energy as a common factor among all things. They list three fossil fuels and describe how fossil fuels were formed. They then tell how much plant debris it took to form one foot of coal.

Learners identify lightning in pictures from the provided Internet site. They study a definition of lightning as a form of heat energy that can be dangerous. They state and illustrate a minimum of three lightning safety rules.

High schoolers recognize that global winds move in specific directions in specific latitudes and describe that in a written form. They relate the motion of the wind belts to historical navigation.

Students view progressive slides of cloud formations and identify which type of cloud is shown as it forms. They estimate the cloud's height while viewing each image.

Students explore the energy changes from a liquid to a solid. They model the arrangement of a solid and the change in states due to changes in energy using desks and chairs. Assessment questions are provided in lesson plan.

Students study how the sun transfers heat to the earth through radiation. They examine how animals absorb energy from the sun to warm their bodies by experiment with chocolate melting. They examine sun safety.
