In this chemistry worksheet, students examine the periodic table and how it is used in the context of interpreting compounds and their structure.

Pupils make observations while eating food. They act out the process of food breaking down in the body and the roles of various chemical components, such as sugar and protein. It concludes with an activity illustrating the process and a...

When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

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...

Students study the scientific evidence about carbon dioxide emissions. They learn to calculate the amount of energy used by different appliances. They complete a worksheet which analyzes the amount of energy that their home uses.

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

What are calories, and how do calorie needs differ from person to person? Here is a worksheet that briefly explains how calories measure the energy supplied by food, as well as suggests the amount of food an individual should eat per day.

Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Students investigate the effects of pollution on marine ecosystems. They read and discuss an article, identify the effects of pollution on marine life, conduct research on local nutrient pollution, and conduct local water quality studies.

Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...

Jump into the classification of animal and plants cells, through this inviting lesson plan comparing Elodea leaves and Epithelial cells. Middle school learners will create wet mounts, write journal entries that compare specimens, and...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

Seventh graders discover the interconnectedness of plants and animals in ecosystems. In groups, they create a food web and discuss the problems when one link of the chain is broken. To end the lesson, they set up a balanced environment...

Carbon is in the air; should we care? Teach the class why it is important to pay attention to carbon levels and how the world population and various countries across the globe affect the carbon levels in the atmosphere. High schoolers...

More of a math lesson than physics or space science, high schoolers take a set of data and plot it on a log-log coordinate system. The write-up for day two was never completed, but day one, "Stars and Slopes," is complex and cohesive....

The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...

Why not review for that chemistry test with a little healthy classroom competition? With a fun and interactive Jeopardy-style game, you can adjust the number of teams, keep track of scores, and even make your own test if the provided...

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Young scholars identify sources of geothermal energy. They watch videos and investigate the sources of geothermal energy.
