What Holds a Substance Together?

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...

In this carbon worksheet, students follow directions and use marshmallows and toothpicks to made carbon dioxide and glucose molecules. Students do this to see how carbon changes as a result of photosynthesis.

Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.

Young scholars will analyze how water enters different soils, how readily it passes through and how much water is held.1. Materials needed for the activity are; pint of clay, pint of sand, pint of loam, newspaper, three frozen fruit...

Learners, through the media of dance and drama, discover how an animal's behavior helps them to survive in the environment. They practice performing or mimicking how a flamingo's acts and positions itself when being observed. The...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

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

Fourth graders participate in a simple experiment that shows the ratio of elements that make up water.

Students watch and predict chemical reactions when different substances are mixed together. They differentiate between solid, liquid, and gas.
