Why are we here? Well, if you happen to be a Golgi body, the answer is simple! Young biologists embark upon a journey through the tiny world of cellular organelles with an engaging lesson from the K20 Center. The activities open with an...

Young geologists begin exploring volcanoes of different structures and states: active, extinct, or dormant. During the lab, they make three models and compare different types of volcanoes, including composite, cinder cone, and...

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different...

Students explore scientific theories and the works of scientists.  In this chemistry instructional activity students develop a timeline  that shows how scientists work was built on the ones before them. 

In "Nuclear Arthmetic," first-time physical scientists examine atomic structure and the periodic table of elements. The are given the formula, "N = A-Z," in which N is the number of neutrons, A is the atomic mass, and Z is the atomic...

Young scientists take a trip into the microscopic world of cellular biology with this practice exercise. Given pictures of different organelles, students must correctly identify specific parts of each cellular structure to demonstrate...

Energize the cells of young biologists with an edible life science activity. Engaging students in exploring the inner workings of plant and animal cells, this activity involves using colored jello and various sweet and...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

For this atom worksheet, students review the structure of an atom. Students also explore radioactive elements and quarks. This worksheet has 10 fill in the blank, 6 true or false, 1 short answer, and 3 multiple choice questions.

In this atomic structure worksheet, students read a story with characters acting as the particles in an atom. They create a trading card for each particle, draw the structure of an atom and sing an atom song.

Rings and golden nuggets contain the element gold, but how small can you break it down before it is no longer considered gold? A helpful presentation explains the basics about atoms, elements, and isotopes through a presentation.

A basic presentation to introduce some of the terminology regarding atomic weight, atomic structure, and atomic number awaits your students. An example of the calculations finding average atomic mass for carbon is given, and a way of...

Students examine the atomic structure of elements.  In this chemistry lesson students organize elements of the periodic table according to their atomic mass, and compare their order within the periodic table. 

This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

Students observe slides of cork cells and discuss the use of microscopes. They view a power point presentation on "Looking Inside Cells" and take notes aligned with the PPT presentation. They collaborate with a partner to create an...

The pre-lab portion of the lesson introduces emerging geologists to the various layers that make up Earth. After completing a sheet on the identification of the layers, class members simulate plate boundaries and their...

Introduce students to cells, and their many parts in this biology presentation. Students see that plant and animal cells have many of the same type of structures, but also have many differences as well. They will be challenged to state...

Beginning with a pre-lab, kindergarteners trace the letters in the word earthquake and discuss what happens in an earthquake. The lab portion allows young scientists realize that earthquakes trigger shaking of different intensities...

Fifth graders search into animal and cell characteristics and their functions in this seven lesson unit. Replicas of the cell are constructed out of Jell-O as students probe the internet for details of the concepts.

In this cell organelles learning exercise, students read the structure and function of different plant and animal cell organelles to determine what organelle is being described. Students write in the 15 organelles into a chart.

In this atom worksheet, students read about Dalton's contributions to the structure of the atom. They answer five questions about Dalton's ideas, the law of multiple proportions and the law of definite proportions.
