High schoolers explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence...

In this physics worksheet, students develop an understanding of the atomic model and how atoms relate to one another through answering the seven questions.

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

A somewhat strangely formatted slide show that contains multiple examples of matter types. The classification and state explanations given would be useful as practice of substance identification and the heating curve may prove to be...

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...

The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Snap to it! Young experimenters use Snap Cubes to model how a larger object is created from a smaller parts. Using a guide, they rearrange their cubes to create all possible arrangements of four and five cubes.

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...

Young scholars verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic...

For this molecular formula worksheet students fill in a table describing elements and chemical formulas. They identify, elements by type and how they bond. The student analyze molecular formulas to identify the number of atoms and if the...

Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.

Students explain that the Standard Model of the atom includes particles beyond protons, neutrons, and electrons. They describe the nucleus as conglomeration of quarks that manifest themselves as protons and neutrons.

In this science molecule models worksheet, student convert 8 molecule models to chemical formulas and 8 chemical formulas to molecule models.

Students explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...

It's molecule magic! Skillful scholars explore the effects of different atoms on molecular polarization using an intuitive interactive. The resource displays the charge at different locations on the molecule, then adapts as the user...

Shock your physical science class using this video to teach the basics of static electricity. Electricity is defined,and electrons are differentiated from protons on an atom model. The use of hydropower and wind are explained as ways of...

Why are bricks more likely to break than bend? Young science scholars peer inside a ceramic block and examine the effects of downward force at the molecular level. Learners can apply three different levels of force before observing their...

Aquapores allow water to travel through cell membranes while keeping other molecules out. The animation offers an up-close look at these parts of the cell membrane. It explores multiple vantage points and shows the importance of these...

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

In this periodic table worksheet, students answers 10 fill in the blank questions by reading information form a periodic table. Then also complete Bohr Models of the atoms of 12 different elements.
