Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Young scholars investigate air by participating in a class experiment. In this matter measurement lesson, students identify air as a gas which consists of mass. Young scholars utilize a windsock or balloon to measure oxygen and explore...

Hydrogen bonds, and polarity are described in this PowerPoint, and the reasons for tension and cohesion associated with water.  The states of water under certain conditions are explained with information about the changes in...

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

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...

Examine how heat can be transferred between systems by reconstructing a diagram on energy flow and solving problems on heat flow and work done.

In this atom instructional activity, students read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds....

Learners explore how various substances change from a solid to a liquid or from a liquid to a solid and how temperature, pressure and nature play an important role in this process. In this melting and freezing...

Pupils make observations while eating food. They act out the process of food breaking down in the body and the roles of various chemical components, such as sugar and protein. It concludes with an activity illustrating the process and a...

Students read the Who We Are Section on Calfee Designs Webpage and discuss carbon usage. They work in pairs to look up the minerals diamond and graphite then create a chart on the properties of each mineral then compare how they differ...

Thirty-seven slides thoroughly shed light upon the four classes of matter: elements, compounds, mixtures, and solutions. Also covered are chemical symbols, molecules, and chemical equations. The colors and fonts chosen for the...

So, this is not technically a worksheet, but rather a chapter of reading material, pictures, and diagrams introducing young biologists to the cell. Cell theory, diversity, size, and shape are described. The internal organization and...

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...

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...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

In this matter and chemical changes worksheet, learners write symbols and formulas for 2 chemical reactions. They write words for 1 chemical reaction given in symbols and formulas. They draw a diagram representing a chemical reaction and...

Young scholars examine the differences between a virus and a bacteriophage. They explore various websites, identify the parts of a virus and a bacteriophage, and construct a model of a virus or bacteriophage.

In this scientific investigation worksheet, students follow the provided procedures to examine the chemical reactions of hydrogen and oxygen atoms and then respond to 1 short answer question.

In this molecules worksheet, students add food coloring to water and heat it up and answer questions about their findings. Students answer 4 questions about heating molecules.

Students make ice cream as a result of viewing changes of states of matter. In this matter lesson plan, students learn how heating and cooling can effect a state of matter to change.

Students explore matter. In this physical science instructional activity, students role play the 3 states of matter forming "liquid" molecules and "solid" molecules with teammates. Students perform an experiment in which the result...

For this kinetic and potential energy worksheet, students read for information and evaluate comprehension. In this multiple choice and fill in the blanks worksheet, students answer fifteen questions.

Learners engage in a lesson that is concerned with the water cycle and different states of matter. They conduct research using a variety of resources in preparation for taking a quiz. Then students take the quiz in correlation to having...
