Second graders read ead the book The Wump World written and illustrated by Bill Peet. Discuss with the students how air pollution can make your eyes water and cause shortness of breath. Students discuss air pollution and give the...

Students compare and contrast the properties of substances and mixtures. In this chemistry lesson plan, students simulate spontaneous mixing by performing a short class activity. They differentiate heterogeneous and homogeneous...

Young scholars perform 3 hands-on activities to help them explain the terms "crest" and "trough" as related to sound, water, and light waves. All three waves types have troughs and crests. The activities use toys to demonstrate the...

Students explain basic principles of aeronautics such as gravity and lift. In this How Things Fly lesson, students visit the interactive, hands-on How Things Fly gallery at the Smithsonian. Students perform three experiments that...

Students examine bubbles. In this early childhood science lesson plan, students experiment with different bubble wands and then share their insights.

Ninth graders describe that matter is made of minute particles called atoms, explain structure and properties of atoms, classify chemicals, locate chemicals on the periodic table, and play Jeopardy.

Students discuss ways our environment becomes polluted. They make a list of ways to keep it clean.

Students make predictions about how sound is formed. They view and discuss a video that explores sound formation and attempt to identify the origin of different sounds.

Students observe the growth of a seed, predict what will happen when seeds are planted without soil, and conduct an experiment using a hydroponics system.

High schoolers use real-time weather maps to determine the likelihood of acid rainfall in a region. Students apply their understanding of interaction between weather systems, land and air pollution, to address acid rain and the effects...

Learners determine its' direction of movement, and list at least five weather conditions associated with the specific front, given animations of several atmospheric variables during a cold front passage. They list at least three weather...

Students explore permafrost.  In this 3 states of matter instructional activity, students identify characteristics of solids and liquids.  Students observe water and soil melting and freezing at various temperatures. ...

In this chemistry instructional activity, students identify and describe that density is the ratio of the mass of the substance to the volume of the substance at a given temperature. They also respond to various questions that refer to...

Students use physics to discuss diversity. In this social interaction lesson, students use their knowledge of colors and filters to relate it to stereotyping and prejudices.

Students collect rocks, identify them, classify them, investigate their properties, and more. In this rocks lesson plan, students also experiment with soil and erosion and weather.

Learners study the different types of weather and how storms form.  In this weather instructional activity students make their own "tornado in a bottle" and create brochures.

Students manipulate a model of a wave in order to solve the wave equation in 1 dimension. By using a model of a wave on a string the student is able to change the tension, length, and mass of the string as well as fix either end of the...

Learners study the process of evaporation.

Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

Fourth graders investigate compost. In this Science lesson plan, 4th graders take notes on the components of soil and its relation to plant growth. Students describe the steps in making compost.

In this lesson, learners investigate the phenomenon of sound! Students compare and contrast how sound travels through solids, liquids, and gases. They explain how length and thickness affect sound. Learners know the difference between...

Fourth graders show the needs of plants met by soil. In this Science activity, 4th graders detail the components of soil and determine which are living or once living and non-living. Students determine the needs of plant growth that are...

Students recognize that the sun is the source of energy driving atmosphere cells. They relate the motion of the atmospheric cells to mantle convection cells. Students recognize that the function of atmospheric cells is to move heat from...

Fourth graders are introduced to the characteristics of a variety of minerals and rocks. As a class, they are shown rocks and minerals and asked to describe them as a geologist would. They work together to measure and record their...
