Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

The PowerPoint opens with video footage of the decomposition of nitrogen triiodide and then explains it with diagrams. Graphs of exothermic and endothermic reactions are exhibited, as well as one for the effect of a catalyst on reaction...

In this science worksheet, students explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

For this chemistry element worksheet, 7th graders complete three pages of activities that help them learn about solid, liquid, and gas forms.

Learners 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...

Learners explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Learners will then work in the lab to identify changes at different stations prior to doing a...

Students conduct research of the history of atomic theory. Information is presented from Democritus and Aristotle to the early Renaissance using the Internet and video.The integration of technology allows for a vast amount of research...

Students observe crystals under the microscope. In this science lesson, students compare how the crystal look like using their eyes, hand lens and microscope. They identify the type of crystal based on the amount of light they allow to...

Students identify the different periodic trends. In this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

In this mixtures learning exercise, students fill in 7 blanks, determine if 4 statements are true or false, match 7 terms with the appropriate definitions, and solve 2 problems. These include topics such as homogeneous and heterogeneous...

Learners develop a concept of the relative size of objects in the nanoscale. They complete an internet assignment using the website,"Scaling the Universe to Your Desktop". Using analogies to common objects they get an appreciation for...

Learners simulate how scientists studied things they can't see like atoms. In this chemistry lesson, students predict what is inside the numbered obsertainers. They design a way to investigate what's inside without opening it.

Students, after observing the elements of a local watershed, explore the need to protect watersheds as water resources for the future. They examine the factors involved with a watershed: geology, ecology, and the effect of man's...

Students are members of the North Carolina Environmental Management Commission. They make recommendations to the "governor" and a panel of his advisors regarding the greenhouse effect and global warming.

Students explore the basic unit of life, the cell in this nine lessons unit. The cell structure of animal and plant cell functions and how they affect our world are probed in this unit.

Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur.  In this matter lesson students divide into groups and complete a lab experiment. 

Students investigate the concept of elements and atoms. They conduct research using a variety of resources and use the information in order to create a class presentation. The lesson includes specific dialogue and steps for the teacher...

Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Students model the arrangement of particles in a liquid. They use the model, to demonstrate how a gas is formed from a liquid with no increase in temperature as energy is added. Pupils model the arrangement and movement of gas particles.

Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...

Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a...

Young scholars describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students...

Students determine differences in concentrations. They have to state the problem they feel exists, consider possible solutions, and develop a plan to come up with for containers whose labels have fallen off. Students base this off the...
