Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Third graders understand that the smallest particle is an atom. In this matter lesson, 3rd graders make a piece of aluminum smaller and smaller to see that what's left is still aluminum. Students recognize that cutting into smaller...

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.

Where does an electron reside? Chemistry scholars determine an electron's "address," that is, what orbital it can be found in. This resource is both instructional and practical,  providing a thorough explanation of energy levels and...

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 roll dice in order to simulate the probability of locating an electron in a certain region around the nucleus.

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,...

Students create models of ionic and covalent electronic bonds to demonstrate their understanding of these chemistry concepts. They explain how both ionic bonds and covalent bonds work so that younger students can understand.

How are chemical bonds similar and how are they different? Provide your young chemists with the resources to more thoroughly understand the concepts of ionic and covalent bonds. Pupils research these topics, diagram examples of each...

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Students describe the structure of atoms, including the particles that make them up. They recognize that key scientists and experiments have contributed to the changes in the Atomic Theory.

Making models is always memorable. For this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

A flashy PowerPoint includes clear summaries of atomic structure and electronic configuration. Dot and cross diagrams will help viewers learn how to draw an atom. As a result, learners should be more clear how electronic configuration...

Students define, identify and illustrate the parts of an atom, and investigate the Bohr atomic model. Students watch a multimedia presentation to understand an atom's parts and their functions. In groups, they create a model of an atom...

Hands-on and real-world applications are great ways to teach mathematical concepts. Creative thinkers examine how ratios are used to create scale models of buildings and structures. They practice working with ratios by looking at a map...

Students investigate what is wrong with the Rutherford atomic model. In this chemistry lesson, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how the atomic model...

In this atom worksheet, students explain how different scientists added to our knowledge of the atom, specifically the structure and parts of an atom. This worksheet has 4 matching and 5 short answer questions.

Eighth graders explain what makes up matter.  In this atoms lesson students define an atom and what its components are and identify properties of elements. 

Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

A two-hour final exam covers a range of physics topics related to electricity and magnetism. It employs a variety of methodologies for assessing your physics learners' understanding and mastery of these concepts. You will need to review...

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

Get to you know your new class members with an ice breaker activity that uses their name and creativity. Scholars write their first name in cursive on a folded sheet of paper, cut around the curved lines, open the paper to view its new...
