Students demonstrate their understanding of a chemical process.  In this exploratory lesson students create a clay animation that shows how a specific type of chemical bond. 

Students study hydrocarbon gases and chemical equations. In this hydrocarbon gases lesson, students work in groups complete a molecular formula worksheet and review alkane prefixes. Students complete molecular models, balance chemical...

High schoolers will draw Lewis structures of common covalent compounds using a Chem 3D computer program. They will predict the shapes of the molecules, complete a data table, and formulate rules for predicting shapes of molecules. In the...

Students work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

Students define and read an article on polar energy.  In this polar energy lesson, students answer questions about the article.  Students participate in activities related to isotopes, half-life and radiocarbon.  Students...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Elements, to the rescue! Scholars first review the periodic table, and then learn about the first 20 elements and their properties and uses in the fourth of six lessons in the Mixtures and Solutions unit. Applying their newfound...

In this color worksheet, students read about light, prisms, the RGB model and the CMYK model. Students match colors with their definition, they draw the color chart, they apply the RGB and CMYK models to make colors and they interpret...

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

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...

A few definitions related to waves open this slide show. Note that the information only covers light waves even though the title mentions sound. Correct the title before using this resource. Another mention is a set of photos of a class...

Learners study atoms and their protons and neutrons.  For this physical setting lesson students work together to complete a lab activity. 

Students conduct a simulation to determine radioactive decay and half-life. Using pennies, dice or sugar cubes as isotopes placed in shoe boxes simulating rocks, they hold five trials representing 1000 years each to find the theoretical...

Tenth graders identify stars based on their line spectra. In this astronomy lesson, 10th graders analyze spectrograph and determine the elements present in the star. They explain the relationship between temperature and star classes.

Middle schoolers examine the concepts of isotopes and atoms.  In this powerpoint lesson, students see the balance in numbers  of protons, neutrons, and electrons create isotopes and ions of certain atoms.

Students collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective filtering...

Students are introduced to the characteristics of crystals and what keeps them together. Using the Periodic Table, they examine the various elements and develop a model of an atom. In groups, they place sugar and salt in petri dishes...

A complete overview of oxidation, reduction, and how electrons are moved in respiration. You could use this slide show to elaborate on the concept of harvesting stored energy, and to summarize the stages of aerobic and anaerobic metabolism.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

Students explore a model that illustrates the spread of HIV through an adolescent population. Acting in the role of epidemiologists, students explore the dilemmas of HIV infection presented by a simulation. Students produce a play, skit,...

Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.
