Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

Learners demonstrate an awareness of air as a substance that surrounds us and takes up space, and whose movement we feel as wind. They predict and describe how local weather conditions affect living things, including themselves.

Students investigate temperature and chemical reactions. They explore the effect of temperature and particle size has on the rate of a simple chemical reaction. In addition, they graph their results and answer assessment questions.

In this biology instructional activity, students explain where the energy of food originally came from. Then the explain one of the principal chemical compounds that living things use to store energy. Students also describe how ATP and...

In this life cycle workbook, 3rd graders complete several different activities in which they analyze different invertebrates, identify arthropods, examine human biology and plants, and study natural environments. 20 different activities...

In this gas worksheet, learners use the ideal gas law to find volumes of gases, pressure of gases, moles of gases, mass of gases and molecules of gases. They find unknowns at standard temperature and pressure and they calculate the...

In this kinetic theory worksheet, students are given fifteen questions about gases and their kinetic energy, how temperature effects kinetic energy, and the results of changing conditions of gases on the kinetic energy. They convert from...

Students learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students make a personal heart profile of an important member of their own hardworking team.

In this experimental design and homeostasis worksheet, students complete 20 sentences with key terms about designing experiments, gathering data, graphing data and determining controls. They also complete sentences about homeostasis and...

In this living environment worksheet, students answer a variety of questions about living organisms, the processes they go through to make food and break down food, absorb nutrients, and release toxins. They explain homeostasis, they...

In this catalysts worksheet, learners use transition metals ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.

Students examine how to convert sunlight to electricity.  In this renewable energy sources lesson students explain how solar cells are used and use a voltmeter to measure the energy produced by a solar panel.

Students perform a series of experiments on gas laws. In this chemistry lesson, students analyze the relationship between temperature, volume and pressure. They create a poster summarizing all the gas laws.

Students recall details about the formation of the earth and early atmosphere. They name the layers of the atmosphere and compare amounts of atmospheric nitrogen, oxygen, and argon. Formulate questions about global warming.

In this food chain learning exercise, students review terms associated with food chains and food webs. Students also recall the water cycle.

Using a simulated air sample, environmental or earth science pupils examine the components. You will need to prepare the faux air by using a hole punch and various colors of construction paper. Each color will represent a different...

Learners examine the acid-base indicator, bromthymol blue (BTB), and what happens to it when you blow air into it or add plants and snails. Through an experiment, they test three different setups of BTB and record the color changes that...

In this environmental worksheet, learners read the sheet that is about the greenhouse effect. They examine possible solutions to the problem.

Fourth graders discuss and identify the components of photosynthesis and the products of this process. They participate in a class discussion about the importance of oxygen, and in small groups act out the process of photosynthesis. ...

In this math and climate activity, students complete a set of 10 word problems, all related to math and climate. A reference web site is given for additional activities.

Students investigate how trees produce their own food. They examine chlorophyll cells with a microscope, analyze a cross section of a log, determine how old the tree was, simulate the distance of the roots, and create a play.

Students identify and explain that remote sensing can detect changes on the Earth's surface that occur over time, and name at least three: urbanization, deforestation, and succession. They select a global change issue to investigate and...

Students explore renewable energy by analyzing a diagram. In this fossil fuel lesson plan, students view a chart explaining the different energy consumption from automobiles and how they impact our environment. Students analyze a point...

In this chemical reaction worksheet, students write 11 balanced equations for 11 word equations, and complete word equations and balance chemical equations for 13 chemical equations.
