High schoolers identify the location and change of the subatomic particles of an atom. They name the three subatomic particles. Students review what they can recall about subatomic particles. They are given a worksheet on the...

In this atomic particles activity, students complete an elements chart comparing atomic number, mass number, protons, neutrons, and electrons. Students write the electron configuration for atoms. This activity has 1 graphic organizer and...

Learners investigate atoms as particles that make up all matter. They examine the mass of matter.

In this chemistry worksheet, students find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.

Students perform flame tests on salts and record the electron configurations for various cations. They analyze and record the results using spectroscopes.

In this electron arrangement activity, students complete two graphic organizers by determining the proton number of given elements from their first ionization energy. Then, they plot graphs of the first ionization energy against the...

In this cellular respiration and photosynthesis activity, students read through the presented material and draw an illustration of the production of ATP. Students answer several short answer questions about the production of ATP, aerobic...

In this atom worksheet, students complete a 3 D graphic organizer for the structure of the atom. They define atomic structure, electron cloud, proton and neutron. They cut out the terms to make flaps with definitions.

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...

Pupils explore ionic bonding. They draw examples of ionic bonding and explain the activities of the electrons of the elements. Students use paper plates and candy to draw electron configurations of given atoms.

Your young chemists will find these slides very informative. Groups and periods of the periodic table are labeled and described according to the charge. Comprehensive explanations of physical and chemical properties and how they relate...

Thorough explanations of the trends in the periodic table of elements make up the majority of this handout. Atomic and ionic size, ionization energy, electron affinity, and electronegativity are presented before giving chemistry...

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

A huge collection of slides introduces chemistry learners to the periodic table of elements, electron configuration, and electronegativity. It opens with the history of today's periodic table, and then details the arrangement. After...

Pupils 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...

For this countdown challenge worksheet, students find the 10 common elements from the human body, earth's crust, and ancient times and color code them. Students fill the atomic number of the elements in a given periodic table.

The fifth lesson of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments include a...

What is space made of? It turns out that there are many compounds found in space! The 10th lesson of a science series provides a list of the compounds found in space and asks young scholars to research the characteristics of these...

In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...

Here is an interesting science lesson/activity which has learners working in groups in order to simulate experiments done at the Jefferson Science Lab. In this one, groups use a pie tin, a Hula Hoops, a marble, and a magic marker to...

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...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...
