The stability of the atmosphere changes on a daily basis. A kinesthetic lesson models how the stability of the air changes as it's warmed by the sun. Learners connect their models to the changing air currents and movement of warm and...

Two lessons explore the connection between energy transformation and a given job. In lesson one, small groups role-play a scenario that showcases the energy transformations that may take place during a job-specific task. The second...

Junior ecologists relate how food chains and food webs route matter and energy through an ecosystem. They trace feeding levels of a food chain or food web through a pyramid of energy. As a reinforcement activity, learners construct three...

First graders explore how earthquakes release energy in a set of hands-on activities. During the pre-lab, they discover how energy from an earthquake releases waves through the earth using a water-filled cup and...

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. 

As your class views each slide, they will be introduced to the organelles and structure of the cell.  Details about structure and function are given and also some trivia about their frequency and population. There is also some...

In "The Nature of Covalent Bonding," chemistry hopefuls demonstrate an understanding of various types of covalent bonds, electron configuration, and resonance structures through fill in the blank, true or false, and matching questions....

After giving basic details about the properties of carbon, some of the common functional groups and molecules are featured. There is some information about specific functions and impact on the human body. The diagrams are helpful and...

Energy comes in many forms, but how do living things get the energy they need to survive and thrive? In a simple, controlled experiment with yeast, water, and sugar, groups make observations about how yeast reacts with water alone, then...

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

High schoolers investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the...

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

Future scientists are introduced to the chemical consequences of burning fossil fuels, learning that fossil fuel combustion leads to the formation of oxides of three nonmetals: carbon, nitrogen, and sulfur, all of which end up in the...

Young scientists gain a better understanding of space, the solar system and its vastness by creating a scale model. Students first need to calculate the distance between each of the nine planets according to the size of their scale. This...

In this science worksheet, students read and analyze information about leaves. Students will consider the 5 questions: How is a leaf like a cook? How is a leaf like a fan? How is a leaf like a pair of lungs? How does a leaf affect the...

Radiation has numerous real-world applications, some of which are relatively safe while others can be extremely hazardous. In this nuclear chemistry project, young scientists choose a practical use of nuclear reactions to...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Advanced chemistry courses typically cover organic reactions. On this reference sheet, the five types of organic reaction mechanisms are explained and an example is shown.  For each, there is also a diagram of the chemical reaction...

Introduce students to cells, and their many parts in this biology presentation. Students see that plant and animal cells have many of the same type of structures, but also have many differences as well. They will be challenged to state...

In this second lesson of the series, pupils learn to observe similarities and differences in photos of the sun and record them in a Venn diagram. Then, small groups practice the same skill on unique images before presenting their...

Diagrams with annotations are shown on each of these eighteen slides, which summarize the processes of respiration. The focus is on the 3-step oxidation process and the Krebs cycle.  Students should be able to follow these slides...

After giving basic details about the properties of Carbon, some of the common functional groups and molecules are featured. There are some details about specific functions and impact on the human body. The diagrams are helpful and could...

Help classes understand heat as a form of energy. A hands-on activity has learners investigate how heat, or the lack of heat, affects the physical state of water. They then connect their discoveries to the water cycle.

Examine the unique graphs coined broken-line graphs. Using the phase change of water for data, learners answer questions related to the temperature and energy at different times in the cycle of the phase change. Questions focus on the...
