Students observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board from...

In this compounds instructional activity, students are given a bag of colored gumdrops that represent specific atoms. They construct ionic and covalent bonds with gumdrops using the key provided and the compounds to build. They fill in a...

Young scholars explore the concepts of force and effort by observing simple machines. In this physics lesson, students attempt to sharpen a pencil without any help, bite into an orange with their lips curled over their teeth, and other...

Students investigate how Hardy-Weinberg Equilibrium is established and what assumptions and conditions are necessary to reach Equilibrium. They model alleles using materials such as index cards, M & M's and goldfish.

Fourth graders study the uniquely diverse structural design of leaves and demonstrate knowledge of interdependence between structure and environment through research, laboratory activity and written summary.

Learners create models of DNA and RNA using string and beads. They use beads representing the four nitrogenous bases of DNA to create a portion of a strand of DNA, and it's corresponding RNA. Then, students examine how many of their...

In this inheritance patterns worksheet, students create a visual of a Zork using chromosome strips to represent alleles from the father and the mother to determine the traits in the offspring. Students translate the genotype to the...

Students examine how to forecast weather. They examine the different types of weather and learn the correct vocabulary.

High schoolers discuss and identify the types of adaptations that are made by different organisms in order for them to survive. In groups, they describe the features of beaks and discuss how it affects their chances for survival. They...

Students observe leaves. In this math and science cross-curriculum leaf lesson, students take a nature walk and collect leaves. Attributes are assigned and leaves are sorted in various ways. Students use non-standard or standard units of...

Students simulate the Earth's revolution around the sun using CEENBoT. In this earth science lesson students calculate the Earth's distance in AU and it's speed of revolution. They explain how the Earth's movement cause seasonal variation.

High schoolers draw a diagram that shows the law of reflection. In this physics lesson, students investigate the relationship between the angle of incidence and angle of reflection. They explain how light travels as it reflects on a...

Ninth graders create a model of a hydroelectric generator. In this physics lesson, 9th graders discuss how energy can be transformed from one form to another. They make a flow chart for different energy generating plants.

Learners 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...

Students create spider webs. In this spider webs lesson, students research various types of spider webs then write a report about  a spider of their choice.  Students also make their own web similar to an orb spider. 

Fourth graders explore the use of technology to monitor and forecast weather. They investigate the different types of weather monitoring and forecast tools. Students interpret radar images and discuss the traditional types of weather...

Young scholars explore how archaeologists and other scientists use different clues to piece together a picture of the past. Students perform activities that allow them to conduct three types of scientific research. They discuss their...

Eighth graders identify different types of adaptation in organisms. In this biology instructional activity, 8th graders explain how adaptation help organisms survive. They complete a worksheet at the end of the instructional activity.

Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

Young scholars research the availability, usage and demand for water in the local area historically and use projections of the availability, usage and demand for water up to the year 2050. They gather data and present the information in...

Students define and differentiate between point source and non-point source pollution. Students discuss various types of pollution including air, water and land pollution, analyze demonstrations and complete a worksheet.

students gather information during field trip to the zoo. They use and present their findings of the types of birds, cats, primates, and other mammals to their teachers and classmates by producing a slide show using Real Slide Show 2.0.

Students build a model of a suspension bridge and test the amount of weight it support. They identify different types of bridges: suspension, arch, girder, truss, cantilever, cable-stayed and moveable.

Students examine the types of hawks found in Illinois and compile a list of them. Using different species of hawks, they compare and contrast their characteristics. They work together to create their own hawk model for the classroom.
