Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Modeling dough and paper cutouts in science class? Learn about how relative age dating concepts, like the Law of Superposition and cross-cutting relationships, can be used to describe the formation of sedimentary layers.

Learn why what goes up must come down in both air and liquids. Investigators discover how convection transfers thermal energy and the movement of particles in liquids and gases due to density differences by viewing an animated video....

Explore how sound travels as waves with a straightforward lesson that explains the basics of waves in relation to sound. The presentation considers sound waves in both open and closed pipes and shows how to calculate wavelength and...

Control the spread of a contagious disease. An applet allows pupils to run a simulation on the spread of a disease. Rules govern how the disease is spread and the length of time it takes to recover. Learners view the spread visually and...

Working in small groups students develop three alternative boat designs. They discuss the rationale for the type of hull, propeller, location of ballast, and type of building material used in their design. They build their boat.

Photosynthesis requires energy and produces food, and cellular respiration produces energy and requires food. An interesting lesson analyzes the factors that affect the rates of photosynthesis and respiration. Classes spend one day...

Here is a resource that is full of potential energy! Learners manipulate charged objects to convert electric potential to thermal energy using a savvy simulation. The resource includes a variety of charge settings and helpful potential...

Students investigate the concept of a model and how it is used to represent something that is real. They recognize how the model can be applied to other types of concepts like the solar system. Students create a scale drawing of a house...

Each student construct a model of a cell on a large cookie, including the parts which were discussed during lecture.? Half of the class will be instructed to make plant cell models and the other half will be in charge of animal cell...

Students discover how to classify things based on their similarities and differences. Students give the characteristics of insects and create a classification list. Given examples of various types of insects, students classify them...

Illuminate lightwaves, even those not visible to the human eye, in a concise activity about the electromagnetic spectrum. Pupils watch and listen to an animated video describing the electromagnetic spectrum as well as frequency and...

Electromagnetic waves travel though empty space, something no other wave type can accomplish. Young scientists learn more about the entire spectrum of electromagnetic waves. They sort cards and apply their knowledge to create models of...

Students play the role of science detectives in an activity used to introduce the scientific method and the concept that blood is not identical and is identified by surface markers. Students must identify an unknown sample of "blood" by...

Fifth graders continue their investigation of the plate tectonics cycle with an exploration of the movement of Earth's crust. During the lab, young geologists conduct an experiment to discover the result of different types of...

Energy transformations happen everywhere, every second of the day. The energy transformation common to most scholars is potential and kinetic energy. The three-week lesson covers multiple types of energy transformations through...

Learners explore mean, median, and mode as they model mathematics in real-world problem situations. The lesson requires the use of the TI 30X IIS.

Engage young biologists in exploring the mysteries of life with this collection of hands-on activities. Enlisting the help of numerous digital resources, students get an up-close look at the structure of plant and animal...

How does the Earth continually repair itself? Explore the answer to this question, and others, with a unit on plate boundaries and interaction. Pupils classify the types of movement at plate boundaries and identify the...

The human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...

Can a coral cure cancer? Take seventh and eighth grade science sleuths to the underwater drugstore for an investigation into emerging pharmaceutical research. The fifth installment in a series of six has classmates research the wealth of...
