5.PS.4: : Describe the difference between weight being dependent on gravity and mass comprised of the amount of matter in a given substance or material.
Weight and Mass
使用平衡测量质量和弹簧秤to measure the weight of objects. Compare the masses and weights of objects on Earth, Mars, Jupiter, and the Moon.5 Minute Preview
5.ESS.1: : Analyze the scale of our solar system and its components: our solar system includes the sun, moon, seven other planets and their moons, and many other objects like asteroids and comets.
Comparing Earth and Venus
Observe the motions of Venus and Earth as the planets move around the Sun. Measure the length of a day and a year on Earth and Venus, and compare the length of a solar day to the length of a sidereal day.5 Minute Preview
Understand the phases of the Moon by observing the positions of the Moon, Earth and Sun. A view of the Moon from Earth is shown on the right as the Moon orbits Earth. Learn the names of Moon phases and in what order they occur. Click Play to watch the Moon go around, or click Pause and drag the Moon yourself.5 Minute Preview
Explore our solar system and learn the characteristics of each planet. Compare the sizes of planets and their distances from the Sun. Observe the speeds of planetary orbits and measure how long each planet takes to go around the Sun.5 Minute Preview
5.ESS.3: : Investigate ways individual communities within the United States protect the Earth’s resources and environment.
Pond Ecosystem
Measure the temperature and oxygen content of a pond over the course of a day. Then go fishing to see what types of fish live in the pond. Many different ponds can be investigated to determine the influence of time, temperature, and farms on oxygen levels.5 Minute Preview
5.ESS.4: : Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
Carbon Cycle
Follow the path of a carbon atom through the atmosphere, biosphere, hydrosphere, and geosphere. Manipulate a simplified model to see how human activities and other factors affect the amount of atmospheric carbon today and in the future.5 Minute Preview
5.LS.1: : Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
Forest Ecosystem
Observe and manipulate the populations of four creatures (trees, deer, bears, and mushrooms) in a forest. Investigate the feeding relationships (food web) in the forest. Determine which creatures are producers, consumers, and decomposers. Pictographs and line graphs show changes in populations over time.5 Minute Preview
3-5.E.1: : Identify a simple problem with the design of an object that reflects a need or a want. Include criteria for success and constraints on materials, time, or cost.
Trebuchet
Design your own trebuchet to fling a projectile at a castle wall. All of the dimensions of the trebuchet can be adjusted, as well as the masses of the counterweight and payload. Select a target on the Launch tab, or just see how far your projectile will go.5 Minute Preview
3-5.E.2: : Construct and compare multiple plausible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Trebuchet
Design your own trebuchet to fling a projectile at a castle wall. All of the dimensions of the trebuchet can be adjusted, as well as the masses of the counterweight and payload. Select a target on the Launch tab, or just see how far your projectile will go.5 Minute Preview
Students assume the role of a scientist trying to solve a real world problem. They use scientific practices to collect and analyze data, and form and test a hypothesis as they solve the problems.
