In this atomic structure worksheet, high schoolers draw a helium atom and show the subatomic particles. They also answer questions about the Bohr model, Dalton's atomic theory and the energy of electrons based on their location in an atom.

Students investigate the question: "How does a hot air balloon work?" They build small hot air balloons ans then lauch them. Students discuss how they think a hot air balloon floats. Pupils are introduced to the use of models as a...

High schoolers create an atomic model using a computer program. In this technology lesson, students identify the difference between radius and diameter. They create circular patterns and spheres based on certain specifications.

In this periods, groups, valence electrons and masses activity, students are given information about all these components of the periodic table. Students identify 4 elements in specific periods and groups, they find the valence electrons...

Students experiment with the laws of motion. In this motion instructional activity, students explore Newton's Laws of Motion. Students work in groups experimenting with different objects and observing different types of motion.

Students draw the model for each of their atoms on Microsoft Word. They go to the internet and search other pertinent information about their atoms. They place this information and their drawings on a PowerPoint presentation to present...

In this creating bonds learning exercise, students create 2-D and 3-D models of the molecular formula provided. Students complete a chart of information about the molecular formula given.

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...

Middle schoolers examine the concepts of isotopes and atoms.  In this powerpoint lesson, students see the balance in numbers  of protons, neutrons, and electrons create isotopes and ions of certain atoms.

Students collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective filtering...

Students study the flow of water in the environment.  For this water cycle lesson students evaluate the consequences of changes in the water cycle using data. 

High schoolers create a model of a column of air and discover one of the reasons why low and high pressure systems exist and why low pressure is often associated with bad weather.

In these creative hands-on activities, learners construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

In this molecules worksheet, students answer post lab questions about types of bonds, factors that determine polarity and molecular geometry. They calculate electronegativity differences in atoms and determine the types of bonds between...

In this atoms worksheet, high schoolers answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).

Tenth graders identify stars based on their line spectra. In this astronomy instructional activity, 10th graders analyze spectrograph and determine the elements present in the star. They explain the relationship between temperature and...

Students investigate Nanotechnology. In this physic's lesson, students evaluate a hands-on model made from chocolate syrup and pretzels to determine the advantages of size.  Students weigh chocolate syrup to determine it's wait...

Young scholars examine solar, hydrogen, electric power. In this research based lesson plan, students will do simple investigations, view videos, discuss, and research how these three types of energy are used for power. They illustrate a...

In this elements worksheet, students review the Bohr model and define negative and positive subatomic particles. Students compare molecules and compounds. This worksheet has 11 short answer questions and 4 problems to solve.

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

Students investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The instructional activity includes background...

Students study atoms and their protons and neutrons.  In this physical setting lesson students work together to complete a lab activity.
