In this compounds worksheet, students name the chemical compounds and determine how many atoms of each element are present. This worksheet has 16 fill in the blank questions.

In this chemistry in action activity, students read about sulphuric acid, the use of metals, the production of titanium and the detection of chemical elements and compounds. Students are given 8 statements about what they should...

In this comet tails and stars worksheet, students read about the star Mira and the vast clouds of gases it emits. They use a photograph from the Galaxy Evolution Explorer satellite to solve 5 problems about the scale of the image, the...

High schoolers discuss the importance of plankton in the ocean ecosystem. In this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global...

Students research chemical formulas and balance chemical equations.  In this chemical equations lesson students complete a class activity on chemical equations and answer questions.

For this reactions worksheet, students write the formula for each reactant and product and then balance the equation. Students have 23 problems to solve.

Students examine physics. In this air movement lesson, students conduct an experiment that shows how air moves based on the pressure it's under. They watch the teacher complete the procedure and then try it on their own in a small group....

Students examine the surface area to volume ratio and how they relate.  For this surface area lesson students complete several activities.

In this elements learning exercise, students complete a graphic organizer comparing lithium, sodium, and potassium observations. Then, they determine how these elements react with water. Students complete three fill-in-the-blank questions.

Sixth graders are introduced to the process of photosynthesis by discussion and then by participating in an experiment. They then answer questions as independent practice project.

In this biology worksheet, 9th graders explain how producers make their own food. Then they describe the food chain and what the end products are of respiration. Students also describe how muscles continue to get energy during high...

For this chemistry worksheets, students calculate the amount of reactants and products are produced by the given equations. Students also calculate the number of moles as well as the mass of the given compounds.

In this human heart worksheet, students read a short passage about the human heart and study a diagram. Students then fill in the blanks to complete the 8 questions about the human heart.

In this chemical reactions learning exercise, students practice writing chemical formulas, word equations, and symbol equations. They also identify the types of reactions. This learning exercise has seven problems to solve.

In this chemistry instructional activity, students predict the reactants and products of chemical reactions. They complete and balance 10 chemical equations.

Students explore what the stoma does for a plant.  In this botany lesson students complete a stomatal peel experiment and measure its densities.

In this 4-H garden project worksheet set, student study the parts of seeds and plants. They make a mini-greenhouse. They complete a career scavenger hunt, tools word search, and experiment to learn more about the effect of water on seed...
