In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Kids complete the phase change diagram as well as define a given set of vocabulary words. Students calculate mass...

Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.

Upcoming chemists construct atom or molecule models out of candy. This is a classic idea that learners really enjoy; however, this lesson plan is vague. There is no instruction about the structure of atoms or molecules. Make sure you...

Pupils study chromosomes and how molecular half life affects them.  In this chromosome instructional activity students complete several lab activities on calculating half life, and cracking alkanes. 

In this organic chemistry worksheet, students answer 8 questions about organic molecules. They draw structural formulas for molecules, they identify classes of hydrocarbons in given diagrams and they draw specific components of given...

In this moles worksheet, learners complete 93 word problems in they calculate the moles, volume, or mass of different molecules.

In this chemistry learning exercise, 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.

Ninth graders first summarize the process of translation, and then they identify and restate the processes of DNA replication, transcription, and translation in their own words. They also define the purpose of each and identify what the...

Students discuss how changing the structure of atoms and molecules can change the properties of a substance. They brainstorm and review their own examples of phase change with the help of a phase change diagram. Students describe the...

Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....

Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.

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.

Eighth graders observe a compound and separate it  into its component parts. In this chromatography lesson students complete and activity that demonstrates how mixtures can be separated into components. 

In this molecules worksheet, students calculate the mass or volume of a certain number of moles of a compound. There are 3 difficulty levels of this worksheet, each one has 6 problems to solve.

In this nutrient biochemistry activity, students complete the blanks with information about nucleic acids and the process. Students also draw a figure referenced in the text given.

Students discover how molecules are in constant motion. Through a simple experiment of water containing food coloring, they observe the drops of coloring move even though the water is still. Role-playing as molecules, students stand up...

Students explain that molecules are in everything living and nonliving. They explain that molecules are too small to see but we can watch their movement.

Students use foam packing pieces to represent molecular positioning inside the four layers of earth's atmosphere. This lesson help students visualize that molecules become thinner as one ascends higher in the atmosphere.

Young scholars combine movement with science in this fun integrated lesson plan. When students are "liquid" they can "melt" or "ooze" at the end and when they are are "solids" they can "freeze" in a shape.

Build a molecule in 3-D. Add single, double, and triple bonds, or a lone pair of electrons to an atom, learn what the molecule's geometric name is, see the bond angles, and manipulate each molecule to view it from all sides. Then study a...

Capillary is described and explained. It is related to surface tension. Examples in botany and human physiology are given.

[Free Registration/Login may be required to access all resource tools.] Discusses elements, atoms, compounds, molecules, and crystals. Looks at mixture and different types of them.

Select an oil or water environment for molecules and observe how they are affected by interactions with their environment and each other.

Try this at-home science experiment to learn that a glass of water molecules contains a whole lot of space.
