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...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

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...

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...

How do scientists identify which elements originate from meteorites? Scholars learn about a sample of material found in a remote location, analyzing the sample to determine if it might be from Earth or not. They study elements, isotopes,...

In this Dalton worksheet, students read about John Dalton and his contributions to understanding the atom. Students are given sample data for Dalton's experiments and they answer questions about the data in his experiments.

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

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...

Eighth graders explain the development of the atomic model over time. For this chemistry lesson, 8th graders research about the scientists who made a contribution to the atomic theory. They create a three-dimensional model based on their...

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...

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.

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

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...

Photosynthesis requires energy and produces food, and cellular respiration produces energy and requires food. An interesting lesson analyzes the factors that affect the rates of photosynthesis and respiration. Classes spend one day...

Students define vocabulary related to the parts of the atom.  In this matter lesson, students navigate the web to find the structure and the forces that affect atoms.  Students complete an experiment with positive and...

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...

Students research and define an atom using a concept map. They design and create a model of an atom, labelling all the parts, and write a journal entry.

Learners compare and contrast how the theory of atomic structure has changed over time. They explore how different people have contributed to our knowledge of the atom and its structure. Students identify how matter is made of discrete...

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,...

An interesting instructional activity takes pupils on a trip through the carbon cycle. A reading passage allows scholars to take notes and make choices about what happens to the carbon on its journey. This third instructional...

The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...

The carbon cycle is natural and has happened for millions of years, so can humans change it? Young scientists play the role of carbon as they travel through the carbon cycle. They complete two rounds, once before the industrial...
