Students explore concept of current in electrical circuits. They examine how energy from the sun can be used to power everyday items, including vehicles.

Students develop a pathogen based upon their knowledge of pathogens and after presenting it to the class, they then suggest ways that the pathogen might be combated. Next they identify possible physical or behavioral changes in a...

Tenth graders study the diversity of life in the world. They classify and sketch organisms into the 6 kingdoms.

Fourth graders are divided into small groups and collect 4 objects from the playground. They take 5 to 10 minutes to classify their groups and discuss their findings including the terms "living" and "non-living". As a class they discuss...

Students explain the difference between dominant and recessive genes, identify what causes differences in the traits of parents and their offspring, and explain how sex is determined. They will also improve their reading and...

Fourth graders explore the bones, joints, and other attributes of the skeletal system.

Students explore the importance of molecular shape and charge in molecular-recognition. They examine the interaction between antigens and antibodies. Students design and build 3-D visual models to represent molecular-recognition...

Students determine which of three beverage samples contains the most vitamin C. They then apply their knowledge to an additional situation. Students use beverages that have a large, definite difference of vitamin C content to...

In this business and statistics worksheet, students read real-life business problems, arrange data, and identify the probability method best used to determine the answer. They identify the type of random sample, draw stem-and-leaf plots,...

Fourth graders explore the muscular system of the human body.

Fourth graders practice reading in the content areas (science) in order to explore the interdependence of the body systems. They answer written questions after reading.

Students discuss different ways to spread infectious diseases. In this bioterrorism activity, students model the rate of smoke emission using CalRoad software. They analyze the effects of airborne release of...

Fourth graders model the activity of an enzyme acting on a substrate and observe relationships. Have students place toothpicks in a pile. One member of the team should break as many toothpicks as possible, in 10 seconds.

Sixth graders explain what a negative feedback system is and they distinguish it from a positive feedback system. They describe examples of how negative feedback is used in both nature and technology. , Students define homeostasis, and...

Learners perform experiment in which they model convection as it occurs in our Sun. They also explain that convection acts where the effect of gravity and heat are present (low density fluids can rise and cool, and high density fluids...

Learners examine the structure and functions of DNA. They discover the effects radon has on one's DNA and how it leads to cancer. They discuss why DNA is so important to us.

Students assess some common inherited traits which are easily observable and note their phenotype for the trait. Students compare their phenotypes to those of their parents and attempt to describe the pattern and manor of inheritance.

Pupils used collected data to distinguish what pets they have or would like to have. They correlate findings with appropriate technology--Excel. At the end of the lesson they tabulate a bar chart and present their findings to the class.

Students create DNA models using colored construction papers. For this biology lesson, students identify enzyme restriction sites. They model how DNA plasmids replicate when taken up by a bacterial cell.

Students examine the work of scientists and determine how they test their theories.

Eighth graders explore the art of conversation. In this giving instructions lesson, 8th graders discuss and respond to rules, play a game, and practice giving instructions to one another. Students are preparing for communicating in English.

Students conduct Internet research on Antisense Oligonucleotide Therapy. They design a puzzle to represent these processes, read and summarize an article, conduct research, and design a theoretical experimental procedure.

Second graders participate in walking a route in a neighborhood with parent volunteers in order to stress the importance of looking and listening for moving cars. They take this "field trip

Students analyze light bulbs and their design. They create filaments and build a circuit for testing the filaments. Through experimentation, students discover how filament wire works. They explore the role of protons, electrons, and...
