Use this word search to practice physical science vocabulary words. This word search allows you to determine the amount of columns and rows you would like to include; however, when you change the amount columns and rows, the word list...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Students observe methods by which air can crush aluminum cans. As water in the can boils and is sealed, the can collapses as it cools. When the procedure is reversed, the can expands to its original shape. After the alternate experiment,...

Students discover simple gas laws by observing an egg sucked into an Erlenmeyer flask. When the flask is warmed, the egg is placed atop it. when both are placed in ice water, the egg slips into the flask. The procedure is then reversed....

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Challenge young scholars' understanding of thermochemistry with this skills-practice worksheet on Hess's Law. Given a series of five multi-step chemical reactions, students must determine the overall change in entropy...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

Students determine the energy content of various snack foods. They measure the temperature changes in various snack foods as the foods are burned in order to determine the foods' energy content. Students create graphs and data tables of...

Students observe a demonstration of light refraction. They experiment with disappearing crystals to further study light refraction.

Students research the importance of Hydrogen as a potential fuel source. They work in groups to used the internet in order to research this topic. They participate in an electrolysis experiment and a power point presentation in order...

Students follow the appropriate sampling protocol and take two measurements of a local water source. These measurements are Transparency and Temperature. This info about local land use and/or water chemistry issues may require further...

Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

In this chemistry worksheet, students use their imagination and the elements in the Periodic Table to solve each of the puns listed on the sheet. Then they create some of their own and write them on the back.

In this chemistry instructional activity, students use their imagination and the elements in the Periodic Table to solve each pun listed on the sheet. There are 24 to complete.

In this chemistry worksheet, students write the balanced equation for the formation of one mole of fat from its elements under standard conditions. Then they write the balanced equation of the combustion of this fat. Students use Hess's...

In this chemistry learning exercise, students calculate to find the molar mass of water. Then they identify how many moles of hydrogen atoms and oxygen atoms they would have in a beaker. Students also write the chemical formula of...

In this chemistry worksheet, students use the periodic table to complete the chart shown, filling in all of the missing information in the blank spaces. They identify and describe various elements found in the periodic table.

In this chemistry worksheet, students find the symbols for 12 elements on the periodic table. They write the symbols on the lines next to the names of the elements to complete a chart.

In this chemistry worksheet, 10th graders write the names for 12 element symbols. They complete a chart by writing the element names next their symbols.

For this chemistry worksheet, 10th graders write the symbols for 12 elements that are named in a table. They complete the chart by writing the names in the blanks next to each element name.

In this chemistry worksheet, 10th graders write the name for each of the 12 chemical element symbols that are shown in the chart.

Students measure the heat of physical and chemical changes in reactions.  In this chemistry instructional activity students determine at what extent changes emit or absorb heat. 

Students analyze everyday materials to determine whether they are acids, bases, or neutral. For this chemistry lesson, students investigate the pH of various house hold products. They discuss why it is important to know if substances are...
