Ninth graders explain how a scanning tunneling microscope works. In this chemistry instructional activity, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their...

In this atomic structure worksheet, students answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms and what the...

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.

Students build a model of an atom using an online program. In this chemistry activity, students discuss the different parts of the atom. They complete an independent research about their chosen element.

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...

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...

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 explore how density changes. Students read an article on density. They observe a ball and ring demonstration and discuss the outcome. Students draw models of the demonstration and explain what happened.

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.

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...

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...

This is one sticky situation! Science sleuths uncover the mystery behind a balloon that appears to be stuck to a wall using an interactive. Learners observe a neutrally charged wall before they manipulate the charge on a balloon. Atom...

When molecules of hydrogen and oxygen are combined, how does water form? Science scholars observe changes in kinetic and potential energy during a chemical reaction in an interactive. The resource features easy controls that allow users...

Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different...

Students experiment with the laws of motion. In this motion lesson, students explore Newton's Laws of Motion. Students work in groups experimenting with different objects and observing different types of motion.

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...

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...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

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 minerals worksheet, students read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...

Students investigate the periodic table, the structure of the atom and the subatomic particles. In this periodic table lesson plan, students complete 5 activities in order to better understand atoms and the periodic table. They use...

In this atoms worksheet, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).
