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

In this science worksheet, students read about chemical changes. Students also answer 3 comprehension questions about the reading.

Students consider the adaptation of life forms through natural selection to fill various niches and accommodate changing environmental conditions. They select an ecosystem and conduct research to provide as much detailed information as...

Students differentiate physical and chemical changes. In this chemistry lesson, students identify five indicators that a chemical change took place. They complete a reflection journal at the end of the activity.

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 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...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

Tenth graders evaluate the physical mechanisms that cause a change in NOx emissions. In this combustion lesson, 10th graders participate in a research project. Students create a presentation of their findings. 

Pupils identify patterns and relationships from data that is collected and solve variables.  In this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

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.

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.

Through discussion, demonstration, and observation of performances by drum groups, learners discover how vibrations create sounds. Through exploration students can infer that when drums are struck they make noise due to vibrations.

If objects have no heat, how do they can gain and lose it? Scholars experiment with heat, temperature, and specific heat of various substances. They create definitions for these terms based on their own conclusions to complete the fourth...

Students investigate friction between different surfaces. In this physics lesson, students research biomaterials that can reduce friction. They calculate efficiency using a mathematical formula.

Tenth graders investigate chemical, physical and mechanical equilibrium. In this equilibrium lesson, 10th graders participate in a physical activity to show equilibrium by some students standing and some students sitting at the same...

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...

Middle schoolers experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.

Students participate in a lesson designed to illustrate these concepts using simple materials. They use Science process skills to observe, measure, predict, make inferences, and communicate while completing the activity. Proper safety...

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.

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...

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.

Fourth graders accurately describe various states of matter, Through experimentation, they change a variable to create a new state of matter. Students record their observations about the way matter is changed and the changes that occur...

Students study the aspects of a forest floor ecosystem, including decomposition, the water cycle, food webs, the needs of living things, and physical vs. chemical change over an extended period. In addition, students conduct observations...
