Students study the different types of metals.  In this investigative lesson students watch a demonstration on the effects of temperature on atoms and take a tour through baone matter.

Middle schoolers explore the unique properties of alkali metals. In this chemistry lesson, students create a mural of fireworks display after researching its different element components. They write a brief description about an alkali...

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

In this mass spectrometer worksheet, young scholars read about how a mass spectrometer determines the elements in gases around Earth. Students answer 3 questions and identify the elements in a graph found by a mass spectrometer.

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. 

Fourth graders paricipate in a demonstration about bond strengths and bond types.

Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

Eighth graders identify the types of bonds elements form. In this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.

Students perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.

Pupils explain the mole concept and use this concept to prepare chemical solutions of particular molarities.

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

How do one's habits and lifestyle choices affect the environment? Through a short online survey, learners will calculate their own carbon footprints then determine how to reduce their impact on the environment through simple steps, such...

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Tenth graders distinguish between chemical and physical properties and changes in matter when given specific examples. They view a video of sports activities. Students chose their favorite sport and design an experiment to improve sports...

In this chemical compounds worksheet, students determine is compounds will act as acids or bases when added to water. Students compare basic, acidic, and amphoteric anhydrides. This worksheet has 15 fill in the blank, 2 short answer...

Students are assigned to groups, and determine each member's role in the group. They will design an experiment to determine a way to produce the three primary and five secondary colors. Students discuss color and mood. They listen to a...

Students create a polymer ball in the lab. In this chemistry lesson, students identify the different properties of the polymer they created. They explain what type of chemical reaction took place.

Students practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.

Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.
