From quantum foam to the universe itself, plus everything in between, what is the scale of the world around us? Inquisitive physicists grapple with the proportions of all things great and small using a fascinating interactive. Scholars...

The fifth lesson of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments include a...

Words, words, words! This presentation uses plenty of them to define the atom, outline the history of what we know about atoms, and explain atomic and mass numbers. That's all! Informative, but not interesting, this slide show would be...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Imagine what would it have been like to watch a dramatic battle of the Civil War in your own backyard. Young scholars ponder this scenario while looking at firsthand accounts from the Battle of Franklin, along with modern photos of the...

Give me a home where electric buffalo roam and I'll show you an ohm on the range. Introduction your classes to potential and kinetic energy, electricity, and renewable resources with a resource that combines observation, direct...

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

Students observe 3 models that show Dalton, Thomson and Rutherford's theories of the structure of the atom. In this structure of the atom lesson plan, students observe each model and write a summary of each theory of the atom.

In this atomic structure activity, 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.

Learners investigate what is inside three different boxes using indirect observations and relate it to the discovery of the structure of the atom. In this atomic structure lesson plan, students explore the history of atomic structure by...

In this atom worksheet, high schoolers 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.

For this masses of atoms worksheet, students complete a chart of 7 isotopes with their isotope symbol, atomic mass, atomic number, and the number of protons, neutrons and electrons. They calculate the average atomic mass of two elements.

In this atomic structure and periodic table worksheet, students complete a table with isotopes, their atomic masses, the number of protons, neutrons and electrons and mass number. They also find the average atomic mass of atoms and...

Students discuss how changing the structure of atoms and molecules can change the properties of a substance. They brainstorm and review their own examples of phase change with the help of a phase change diagram. Students describe the...

Students investigate the structure of atoms. Students read information about the Rutherford model, the Bohr model, and the Quantum Mechanical model examining each for its scientific validity. They watch a PowerPoint presentation of alpha...

In this atom worksheet, students complete a 3 D graphic organizer for the structure of the atom. They define atomic structure, electron cloud, proton and neutron. They cut out the terms to make flaps with definitions.

Eighth graders read and interpret the Periodic Table. They also make decisions on how to group and arrange different kinds of matter and draw the structure of atoms of pure elements. Finally, 8th graders contrast and compare basic...

Rutherford performed his famous experiment in 1907 with Marsden, showing the true atomic structure. This interactive simulation compares Rutherford's historical experiment to the Plum pudding model of the atom. In both models, alpha...

Changing the number of neutrons in an atom makes it an isotope, but it does not change the element. Pupils complete logic puzzles, matching isotopes with their unique number of protons, neutrons, and electrons. Either on paper or timed...

Students explore atomic structure. They observe a video on atomic structure and complete a Venn diagram on the parts of the atom. Students create their own graphic organizer on the parts of the atom using Inspiration software.

Atomic structure is reviewed with connection to the gain or loss of electrons. The movement of electrons and the resulting behavior is summarized. Practical uses of static electricity is explained, with diagrams of the most common...

A simple activity for introductory chemistry classes is thoroughly explained in this lesson plan. Each individual receives a sealed box containing an unknown object. Inquisitors use indirect evidence to draw conclusions. This activity is...

Almost a complete lesson in itself, this presentation will enhance any bonding and compounds unit. The concepts included are charges of atoms lending to particular molecular structures, the stability of bonds and how to diagram them....

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures.
