PHYSICAL SCIENCE-During this module, students observe the properties of five household substances--alum, salt, cornstarch, baking soda, and talcum powder--and investigate changes in the properties of those substances as they react with water, vinegar, red cabbage juice, and iodine. Because students often think of chemical reactions as "magic," this module helps students build an understanding that chemicals undergo predictable changes that can be controlled. The students use the processes of scientific inquiry, including fair testing (cont
EARTH & SPACE SCIENCE-Students begin this module by using their senses to observe and describe the weather around them. From their sensory observations, students identify patterns, such as seasonal changes, and general weather conditions. Because sensory data usually are not accurate, students use tools, such as thermometers, rain gauges, and wind speed indicators, to describe weather conditions accurately. Teams of students use the tools to collect data of changes in the weather over time and then use their data to describe and compar
EARTH & SPACE SCIENCE-In this module, students explore and describe the position, appearance, and motion (or apparent motion) of objects in the sky, specifically the Moon, the Sun and the stars. They use their shadows to determine the changing position of the Sun in the daytime sky and use direct observations to describe the changing position of the Moon during the day and at night and of the stars in the nighttime sky. Students also observe that the Moon appears to change its shape every day in a repeating pattern that takes approxima
