Watch budding chemists interact with the resource on chemical interactions. In the unit, six lessons provide an overview of basic chemistry, from understanding the development of atomic theory to distinguishing between ionic and covalent...

In this location of electrons worksheet, high schoolers read about the quantum mechanical model of the atom and the location of electrons. They complete a table given eleven elements with the sublevel notation, the Bohr notation and the...

Students become familiar with the variables that control Earth's solar energy supply. They explore the source and nature of solar energy, the genesis of radiation, and the structrue of the Sun, gas spectra are observed and sample...

Students construct a food web to learn how living things in an ecosystem are interconnected. In this food web simulation lesson, students will be assigned an animal and the teacher will represent the sun. Students and teacher discuss...

Students experiment with the concepts of absorption and reflection of radiant energy.

Students demonstrate the greenhouse effect. They recognize that relatively small changes to our environment can stimulate significant climate changes. They determine that the "scientific method" is a process of testing hypotheses and...

For this air pollution worksheet, students use an online simulation called "Smog City" to manipulate different conditions that affect air pollution. Students answer questions about the health effects at peak ozone levels for different...

Young scholars analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies...

Students calculate pulse rates to determine level of exertion. In this human body lesson, students hike up a hill or steep slope and take their pulse. Students observe their breathing and energy level then record data. 

A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

First graders, in groups, discover which colors absorb heat and which colors best reflect heat. They do this using the scientific method.

Yeast and sugar go beyond the pantry and into a fuel experiment. Use these common baking ingredients to assist your class in creating ethanol, a natural fuel. Pupils observe the process and gather information to elaborate...

Do not overlook this set of lessons just because your school does not have a data analysis system. There is plenty of material here to administer a complete mini unit on the formation, distribution, and properties of coal. Since it...

Learners differentiate between current and static electricity, conductors and insulators, explain how energy is converted from chemical to electrical, measure voltage of batteries, collect data on voltage, and predict voltage of...

Fourth graders study about food chains. With the assistance of a local biologist, Students hike the school trail system. They explore ecosystem and collect data by charting the organisms found and identifying the energy source. They...

A fuel cell is where the jailer keeps gas guzzlers. Scholars review chemical reactions, chemical bonds, and chemical structure in order to apply these concepts. Participants construct fuel cell kits, using electrolysis to run the car and...

Young scholars investigate conservation laws using a potato launcher. In this physics lesson, students measure angles, time and distance of the potato. They discuss applications of experiments like this.

Ninth graders examine how dark surfaces absorb more light than light surfaces. They perform an experiment that compares various surfaces abilities to absorb heat, then record and analyze the results.

Yes, Virginia, there really is a reader's theater script for "The Night Before Christmas." The exercise is a great way to productively channel pre-holiday energy.

Students calculate the amount of food calories found in an individual peanut. In small groups, they set up the experiment so that a burning peanut will heat water above it. Using the temperature change and volume of the water they...

Students examine the many types of electromagnetic waves, the concept of an EM wave, how James Clerk Maxwell proposed a slight modification of the equations of electricity, Heinrich Hertz and his radio-frequency, wavelengths, and light...

In this atomic structure activity, students solve twelve problems related to wavelength, frequency, electron transitions, emission spectra and quantum number.

We have all heard the debate about teaching both theories, but an innovative lesson takes the discussion to a new level. Scholars research and debate Newton's Law of Gravitation versus Einstein's General Theory of...

Introduce youngsters to the term ecological footprint. Learners identify ways in which humans affect the environment. They look at the problems associated with the use of natural resources, and focus on ways to preserve natural...
