Making and Recording Observations
Investigation One introduces students to the formal process of making and recording observations as they investigate whether different materials can be added to and separated from the water. As students are guided towards finding and recording the details of their observations through drawings, they discover that some of the substances can be separated using a sieve, while others cannot. In addition, students learn that labeling their drawings provides a way for their observations to be shared and discussed with others
In Investigation Two, students will build on their experience by investigating the types of observations that can be made with four of their five senses: sight, touch, hearing, and smell. Students explore the relationship between senses and observations by investigating the appearance, texture, sounds, and smell of three solids and three liquids. As a part of their analysis, students complete a data table that correlates the type of observations that can be made with each sense. In addition, through analysis of their observations, students gain an initial understanding that for both different solids and different liquids there exist properties that are both similar and different.
During Investigation Three, students will be introduced to the concept of patterns. By observing objects in a sequence, students will discover patterns and predict the next item in a sequence. In addition, students will explore patterns that exist in drawings, music, and speech. Through experiments, students will learn how to determine if an object or organism exhibits symmetry and that symmetrical objects can be divided into equal parts. As a result of their observations, students will learn how to recognize patterns in living and non-living things and will discover that the repeating part of a pattern differs between patterns.
