Students observe and sort tree leaves. In this earth science instructional activity, students observe the attributes of real leaves and measure leaves using Unifix cubes.

Students experiment to observe air and its mass.  In this air lesson plan, students use the scientific method to complete experiments that demonstrate the properties of air. Students view a video as follow-up.

Students study the biodiversity in pond water. In this biodiversity lesson plan, students observe 3 samples of pond water using a pond water identification sheet. They record their findings and identify the organisms they find, the...

Students, after observing the elements of a local watershed, explore the need to protect watersheds as water resources for the future. They examine the factors involved with a watershed: geology, ecology, and the effect of man's...

Students investigate safe laboratory procedures, classroom management guidelines, and group roles and procedures. They study a set of safety guidelines with their parents, and to sign a contract stating that they understand the...

Students in second grade are paired with fifth grade computer research buddies. They observe the characteristics of caterpillars, and identify the four stages of the caterpillar to butterfly life cycle. They graph the number of...

Students connect rock and mineral formation with the changes rocks and minerals undergo at the earth's surface. They observe changes produced by weathering and relating these observations to chemical processes such as oxidation,...

High schoolers investigate osmotic balance in living cells. For this osmotic balance lesson plan, students use elodea leaves to study the effects of salt solutions on the cell. They compare the changes in an elodea leaf with salt water...

Third graders research spiders and insects through a variety of Internet sites and compare them.  In this spider and insect lesson plan, 3rd graders complete a Venn diagram comparing and contrasting insects and...

Fourth graders provide a habitat for live mealworms and observe their life cycle. In this animal life cycle and scientific inquiry lesson, 4th graders create a habitat for a live mealworm and observe and record related data as it grows....

Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

Students use field research and traditional research to identify migrating species of birds as well as their migratory patterns. Students generate a list of questions regarding migration and a plan to research the questions. A field...

Students explore the water cycle. In this earth science lesson, students observe and measure water in a closed container and in an open container. Students record their observations and compare their sets of data to draw conclusions...

Students, in groups, observe, collect data, and analyze mammal behaviors.

Students observe the effects of acid rain on plants. They simulate an experiment using vinegar or lemon water. They observe the impact of acids on plants and recognize how acid rain can affect the environment. They examine their plants...

Learners observe a local area for living organisms and their habitats.  In this local ecosystems instructional activity, students complete an online field journal.  Learners share their findings and sort them into categories....

In this water cycle instructional activity, 3rd graders conduct an experiment where they observe and calculate how water transpires in different types of trees.  Students engage in a class discussion and use Venn Diagrams to compare...

Fourth graders study food chains, producers, consumers, and decomposers. They play a food chain game and create food chain mobiles or posters. They take a nature hike around the school and observe various parts of a food chain.

Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe what happens when they try to put two kinds of matter into the same space and conclude that solids, liquids, and gases occupy space.

Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe water evaporating from an open container and water evaporating and condensing in a closed container. The students assess that a...

Young scholars observe and identify insects in their local. They record their observations by drawing a picture of the insect and writing a description.

Young scholars construct a movie using Landsat images to observe changes over time on Earth. In this satellite images lesson plan, students observe changes in land use over time and document one type of change they observe. They produce...

Students explore the parts of a flower. In this flower structures lesson plan, students study a model of a flower and dissect a flower. They label each structure of the flower and observe the pollen grains and ovules under the dissecting...

Students investigate gravity, force and motion. In this motion of objects instructional activity, students drop various objects from a jungle gym and collect, measure and observe their data. Students describe the forces that affect the...
