Technology can help save money and add convenience. The resource offers a free textbook for a complete Chemistry course. The text begins with a review of the scientific method and continues to explain topics such as chemical bonding,...

Seventh graders distinguish between physical and chemical changes in both natural and technological settings. They identify the reactants and products for a given chemical reaction. they then write simple chemical equations given the...

Students examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

Scholars shake their way to understanding half-life with the help of candy. They observe and record which side candy lands on to graph the exponential decay in the fifth lesson of seven integrating chemistry and algebra. Combining...

In this reaction rate worksheet, students determine the molecularity of a reaction plus show that the predicted rate law equals the experimental rate law. This worksheet has 3 problems to solve.

Students design and construct a paper rocket that can be launched with a drinking straw. They participate in a lecture and read an article about rocketry and how Newton's Third Law applies to rocket launches. Each student constructs...

Students investigate the concept of the Einstein's Theory of Relativity while conducting research using the internet and following the outline of the objectives to guide the information search. The lesson includes background information...

Students are assigned to groups, and determine each member's role in the group. They will design an experiment to determine a way to produce the three primary and five secondary colors. Students discuss color and mood. They listen to a...

Students examine why Einstein rescinded his German citizenship when he was a teenager. They examine what aspects of German life did Einstein disagree with in his early years.

Students work with a partner to determine the identity of an unknown element based on given descriptions. Groups use classroom textbooks, encyclopedias, and science internet sites to identify their unknown element then write a report as...

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

Learners calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.
