There is 30 percent more carbon in the atmosphere today than there was 150 years ago. The first lesson in the four-part series teaches classes about the carbon cycle. Over two to three days, classes make a model of the cycle,...

Explore the excited states of atoms through an interactive lesson. Scholars adjust the initial speed of atoms and observe the kinetic energy of the system as the atoms interact. As they change the initial speed and location of the...

Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Here's a stat for your pupils: 18 percent of the human body is carbon! Part 10 in the series of 12 takes pairs on an adventure through the carbon cycle. After a class reading about carbon, pairs read and choose their own adventure...

In this Bohr model and wave mechanical model worksheet, students read about the differences between these two models of the atom. Students answer four questions about these models.

Upcoming chemists construct atom or molecule models out of candy. This is a classic idea that learners really enjoy; however, this lesson plan is vague. There is no instruction about the structure of atoms or molecules. Make sure you...

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

Positive and negative numbers are everywhere in the world around us. Whether it's charged particles in atoms, a hot air balloon rising and falling in the sky, or a series of bills and checks being delivered in the mail, this...

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...

In this location of electrons worksheet, students read about the quantum mechanical model of the atom and the location of electrons. They complete a table given eleven elements with the sublevel notation, the Bohr notation and the...

Students construct models of hydrocarbon molecules using candy and toothpicks. In this hydrocarbons lesson plan, students are given a sheet with the molecular formulas of hydrocarbons. As a group, they construct each molecule using...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

In this molecular model worksheet, students use a molecular model kit to construct 13 different molecule models. After constructing the molecules, the students complete 32 short answer questions.

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...

Neatly organized and easy to read, this chart summarizes five different molecular shapes: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. It associates shapes with electron pairs and atom arrangement and lists...

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

Electricity travels at the speed of light, 186,000 miles per second. Through a simulation, classes see how the structure of energy bands in crystals of atoms determines how materials conduct electricity. Participants can change the...

Learners see how electrons are transferred in the bonding of NaCl. They then create models of NaCl using styrofoam balls and toothpicks to assist them in explaining the formation of ions and ionic bonding. 

In molecules, bonds rotate about the nucleus due to the repulsion of subatomic particles. In a simulation, learners manipulate the bonds of a molecule to meet the atoms' needs. They can then see the specific molecular shapes of five...

Students explain scientists' ideas about the structure of the atom over the last century. They develop a pictorial history of the changing ideas about the atom and write a caption describing the scientific thinking behind the model.

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...
