3: Physical Science
3.1: Give examples of chemical changes such that when a new material is made by combining two or more materials, it has properties that are different from the original materials. Describe how physical properties are not dependent on size or volume of a material.
Density Experiment: Slice and Dice
3.3: Explain that objects move at different rates, dependent on the distance traveled and the amount of time it took to travel a given distance. Demonstrate that changes in speed are caused by forces: the greater the force exerted on a particular object, the greater the change in speed.
Free Fall Tower
3.4: Demonstrate how a warmer object transfers heat to a cooler one by contact or by radiation at a distance, so that the cooler object gets warmer and the warmer object gets cooler. Demonstrate that when heat is made to flow into an object by putting it in contact with a hotter object, its temperature increases.
4: Earth and Space Science
4.1: Observe and describe the pattern of weather changes throughout the year and explain how weather can be forecasted by examining air masses that move across the surface of the earth. Describe how different aspects of weather can be measured.
4.2: Describe how the appearance of the sky is affected by the daily rotation of the earth on its axis. Draw diagrams depicting the motion of the earth around the sun in a year?s time. Describe the cycle of the moon, including how the shape of the moon changes. Observe and explain the uses of telescopes.
