Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to...

Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

Students investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...

Let's make coal flowers! With this fun activity, young learners watch and learn as they grow crystals! With simple household materials and the instructions included in this lesson plan, your class can grow their own crystals. Learners...

Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.

Learners review what they know about non-renewable energy, compare and contrast advantages and drawbacks of each type, such as cost of energy sources, feasibility, air pollution, water pollution, and other risks, and create table listing...

Young scholars illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect...

Young scholars observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

Discover the change of the seasons by modeling the Earth-Sun system. Learners model the orbit of the Earth around the sun and explore how and why the patterns of winter and summer occur.

Students experiment with silly putty.  In this chemical changes lesson students work in groups, perform tests and collect data.

Learners determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

Fifth graders mix vinegar with different substances and explore the reaction. They record data from the experiment. Students examine chemical change, reaction, physical change and physical reaction.

Eighth graders observe evidence of chemical reactions.  In this chemical reactions lesson students study chemical processes and complete a lab activity. 

Third graders are presented with the problem of: Do all liquids evaporate at the same rate? The instructional activity contains adequate background information for the teacher. They participate in a lab experiment in order to test the...

In this energy transformations worksheet, students fill in the objects to a chart for which one would fit each energy transformation, and fill in the blanks to a chart about which energy transfer fits each object. Students complete 6...

In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

In this science activity, students are using the laws of thermodynamics and a basic knowledge to fill in the sentences with the correct words.

Fourth graders accurately describe various states of matter, Through experimentation, they change a variable to create a new state of matter. Students record their observations about the way matter is changed and the changes that occur...

Students create products from studying about matter that include: Make a "T" chart with matter and non matter items. Write a poem, song, or rap about matter. Five vocabulary words from the chapter must be included in the poem.

Third graders use a literature study in order to investigate how organisms effect an ecosystem. They are asked questions about change taken from the book. Students also take a nature walk to make field observations.

For this earth and beyond science worksheet, students read through 11 pages of information on weather, global warming, climate change and other related topics. There are many website links on the pages that provide additional information...

Students study energy sources to learn about fossil fuels and environmental concerns. For this energy sources lesson, students watch demonstrations for various energy examples. Students find hidden pennies, make a bar graph on their...
