Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

learners convert the temperature readings from degrees Celsius to degrees Fahrenheit. they predict and create a graph of what the graph of altitude (x-axis) versus temperature in degrees Fahrenheit (y-axis) might look like.

In this water on planetary surfaces learning exercise, learners read about the Galileo spacecraft and the surface of Jupiter's moon Europa. They read about the energy needed to keep the water in a liquid state on Europa. Students solve 4...

Students discover types of energy. In this physics lesson, students discuss ways to power a car a design a model car kit with an alternative form of energy.

Students work together to create a scale model of the solar system. They write a descriptive paper and a paper comparing and contrasting the Earth to Saturn. They discuss their writings with the class.

Students view NASA images and movies of Venus, Earth, and Mars to deduce weather patterns and manipulate computer models to test competing hypotheses. They manipulate computer models to investigate the influence of solar distance and...

Students create an awareness of the distance between the planets and the complexity of the solar system through a model of an active solar system. they incorporate physical education and math with the ability to convert distances of each...

Sixth graders explore space science by measuring distances between planets. In this solar system lesson, 6th graders view a Bill Nye video and discover the conversion between the metric system and imperial measuring systems. Students...

In this bellwork on the electromagnetic spectrum and planets worksheet, students answer questions about the information determined using a spectroscope, the geocentric and heliocentric models of planet rotation and the planets.

Students explore the relationship between the earth, sun, and moon in our solar system. They create a moonrise/moonset chart, perform a dance that models the moon phases, and create a Styrofoam model of the moon's surface.

Learners complete a series of activities to better understand space studies. In this space science lesson, the teacher is provided with a number of activities for students to complete such as finding words that begin with the prefix...

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

First graders investigate how the sun warms the Earth and examine the rotation of the Earth and the sun. They create an illustration of the sun, examine a solar system model, and listen to the book "The Sun: Our Nearest Star." They also...

Students explore the concept of expressing numbers in scientific notation. In this scientific notation activity, students understand the importance of using scientific notation by finding real world examples where scientific notation is...

Students become familiar with the members of the solar system and planetary order. They identify differences and characteristics of individual planets. Finally students visualize the great size of the solar system and make the image more...

Students arrange various pictures of the Earth to identify its journey through space. In this Earth's rotation instructional activity, students use models of the Earth and demonstrate its journey through space. Students complete the...

Fifth graders investigate the Earth's rotation and revolution and the moon's orbit around the Earth. They participate in a class discussion about how night and day occur, and take notes. Next, they watch a video about the solar system...

Students are introduced to the concepts of maps as scale models of the whole. After a brief lecture on creating and using an accurate scale when drawing and reading a map. They create a scale drawing of the floorplan of their homes.

Students create scale models of Earth, the Moon, and the distances within the universe. Working in groups, they construct their models of Earth and the Moon on a scale of 50:1 and calculate how far apart to place their models. They...

Students construct a model of a comet nucleus using dry ice. They add other materials and describe the features. They complete related exercises on an Internet Web site.

Comets are also known as dirty snowballs or icy mud balls. With your super scientists, create a model comet nucleus to discover how they are made and take part in a scientific discussion to learn how it behaves.

Saturn's rings are made of dust, ice, and solid chunks of material. Individuals use spectrographs in this final installment of 22 lessons to determine the atmospheric elements. They analyze spectrums from Titan's atmosphere and...

In this interactive Internet  assignment, physical science investigators answer 11 questions about the atom, the subatomic particles, and atomic structure. They can click on "Reveal Answer" to discover if they are correct. They also...

Ninth graders produce a projected, pinhole image of the sun and from measurement of the image and projection distance, calculate the actual size of the sun. They estimate the sun's apparent brightness from different planet.
