Students diagram a plant. In this Science lesson plan, students explore the concept of photosynthesis focusing on the oxygen production. Students calculate the amount of plants needed to filter the air in their classroom.

Fifth graders use modern technologies which allow them to gain a new, dynamic, and intersting understanding of themselves, their community, and the world. They focus on environmental education and the effect of the environment on plant...

Students conduct experiments with plants.  In this photosynthesis lesson, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula for...

In this fractions in chemistry worksheet, students solve 2 problems where they state all the answers as simple fractions or integers. They determine ratios of molecules in gasoline and they find ratio of molecules in the creation of...

Learners investigate air by participating in a class experiment. In this matter measurement lesson, students identify air as a gas which consists of mass. Learners utilize a windsock or balloon to measure oxygen and explore it's true...

Students reinforce math skills while learning about best practices for protection of water quality in the management of animal feeding operations. They make a table to show results of their calculations and compare and justify findings...

In this atoms and sugar molecules worksheet, students are given the structural composition of the sugar molecule maltose. They determine the number of each type of atom in the molecule, they find the ratio of hydrogen to oxygen atoms and...

Livestock managers reinforce math and science skills while learning about the nutrients found in manure. They predict which animal produces the largest amount and which animal's manure contains the most nitrogen. Finally, they compare...
