Fourth graders use damp sand, a baking pan, and water to simulate erosion. In this erosion lesson plan, 4th graders participate in a simulation to show what moving water does to land.

Students design water filtration systems. They draw sketches and write paragraphs about their systems. After presenting their systems to the class, each group then builds their system and determines its effectiveness for purifying...

Young scholars view a video about how human actions impact the environment. They design a set of experiments to address some of the problems and issues raised by the video.

First graders observe the effects of varying amounts of water, sun, and air on lima bean plants. They also predict and describe their outcomes in a written report.

Students examine the rock cycle and the path that rocks go through to rearranged in different ways. They define key vocabulary terms, then in small groups conduct a variety of experiments using crayon shavings as simulated rocks and...

Students gain a better understanding of the worm and its role in the recycling of organic materials into simpler forms by constructing worm bottles and observing for 60 to 90 days.

Students, in groups, take samples from a creek and keep a field journal on their samples. They also perform tests on their samples.

Learners observe and classify the permeability of a variety of materials.

Students participate in several activities on seed exploration. For this biology lesson, students classify seeds according to their dispersal method. They explain the different adaptations plant have to disperse their seeds.

Students, after researching and brainstorming about aquifers and locating aquifer maps of Texas, participate in the building of a model of an aquifer complete with a pumping station. They also answer a variety of questions at the...

Student learns about the life cycle of plants by watching a time-lapse video. This activity provides students with further evidence that all living things grow and change as they progress through their life cycle. Student conducts a...

Students construct and maintain model of natural habitat, suggest improvements to the model of the natural habitat to make it more realistic and habitable, and demonstrate careful observation and recording of how animals survive in their...

Students complete a variety of activities related to the physical characteristics of minerals. They classify and group candy, classify rocks and complete a Pet River Rock worksheet. Students try to guess which rock goes with each...

Students think about the historical development of the scientific method. They design an experiment that replicates van Helmont's, using only specified materials. Pupils then improved upon van Helmont's procedure and also consider the...

Students describe the movement of water within the water cycle and identify the states of water as it moves through the water cycle.

In this trees lesson, 4th graders read the book, A Tree is Growing and complete a KWL chart on how trees grow and how they are used. Students research the symbiotic relationship of humans and trees, create tree collages, plant a...

Fourth graders describe the difference between minerals (composed of the same substance throughout) and rocks (composed of two or more minerals). They recognize that there are three classes of rocks: igneous, sedimentary, and metamorphic

Students examine a crushed rock and sort the minerals they find in that rock by color and other properties.

Students relate the states of matter and clouds.  In this environment lesson, students create a chart of information they know about clouds.  Students put an ice cube in a bag and tape to a window. Students watch for...

In this environmental awareness worksheet, students complete 8 pages pertaining to waste, landfills, recycling and composting. Included are: matching words and definitions, crossword puzzle, scrambled letters, a code, word search and a...

Students study how weather is measured. In this climate lesson plan, students research how samples of the ocean floor reveal facts about the climate thousands of years ago. Students use clay samples to create layers that simulate real...

Students role-play how organisms adapt to their environment. They play 20 questions with plant and animal habitats. They create a web of life to demonstrate how each plant and animal relies on the other for survival.

Third graders keep a journal and record the growth of their plant everyday over a two week period. With an observation written down for everyday of the week, they draw a picture of their plant in their journal on Monday and Friday...

First graders drop items into water, and discuss why some things float and others sink.
