Looking at evolution in detail, this thorough worksheet has complex questions requiring details and explanations of natural selection and diversity. Various examples of biological characteristics are available, and students choose the...

Students identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.

Students discover how temperature effects the solubility of solutes by experimenting with a range of temperatures. They develop skills for observing, inferring, measuring, comparing and contrasting.

In this balancing chemical reactions worksheet, students balance equations, identify electrons gained or lost in atoms and identify the number of atoms of each element for the reactants and products in equations. They also answer 3...

High schoolers examine the definitions of biomas gasification and generate their own biomass gas.  In this renewable energy lesson students collect gases and roast a marshmallow. 

Students explore motions, forces and magnetism. They investigate magnetism as a force and examine the construction of a magnet. Students examine the force that magnetism produces.

In this reading comprehension activity, students read a passage pertaining to laughter and then respond to 5 true or false questions regarding the passage.

Students identify the effect of light on objects. In this scientific inquiry lesson, students use a chart to write a hypothesis about what will happen when colored construction paper is left in sunlight. Students observe and discuss the...

Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to...

Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

Learners investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...

Let's make coal flowers! With this fun activity, young learners watch and learn as they grow crystals! With simple household materials and the instructions included in this lesson plan, your class can grow their own crystals. Learners...

Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.

Pupils review what they know about non-renewable energy, compare and contrast advantages and drawbacks of each type, such as cost of energy sources, feasibility, air pollution, water pollution, and other risks, and create table listing...

Students illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect of...

Learners observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

Discover the change of the seasons by modeling the Earth-Sun system. Learners model the orbit of the Earth around the sun and explore how and why the patterns of winter and summer occur.

Students experiment with silly putty.  For this chemical changes lesson students work in groups, perform tests and collect data.

Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

Fifth graders mix vinegar with different substances and explore the reaction. They record data from the experiment. Students examine chemical change, reaction, physical change and physical reaction.

Eighth graders observe evidence of chemical reactions.  In this chemical reactions lesson plan students study chemical processes and complete a lab activity. 

Third graders are presented with the problem of: Do all liquids evaporate at the same rate? The lesson contains adequate background information for the teacher. They participate in a lab experiment in order to test the scientific...
