How can we learn about living things around us?

How can tools help us learn more about living things?

1B(K-2)#2: Tools such as thermometers, magnifiers, rulers, or balances often give more information about things than can be obtained by just observing things without their help.

6D(K-2)#1: People use their senses to find out about their surroundings and themselves. Different senses give different information. Sometimes a person can get different information about the same thing by moving closer to it or further away from it.

Class list What We Would Like to Find Out about Pond Snails and discussion about pond snails (See Preparation Step 4 on page 91 and Procedure Step 4 on page 92 in Teacher's Guide.)
  • Do students list items that can be found out by making detailed observations of the snails?
  • Do they suggest using hand lenses to make observations?
What are some ways to describe objects? 12D(K-2)#2: Draw pictures that correctly portray at least some features of the thing being described.

12D(K-2)#1: Describe and compare things in terms of number, shape, texture, size, weight, color, and motion.

11B(K-2)#3: One way to describe something is to say how it is like something else.

  • Record Sheet 7-A: Observing Freshwater Animals (See Procedure Step 2 on page 92 in Teacher's Guide.)
  • Class Venn diagram—Snail portion (See Procedure Step 8 on page 93 in Teacher's Guide.)
  • Do the students' drawings accurately contain one or more identifying features?
  • Are students' written observations descriptive and accurate?
  • Are their drawings and written observations improving in quality and accuracy?

* Essential/Unit questions are major questions driving the unit. They are directly aligned with the benchmarks. No single lesson addresses each question in its entirety. By the end of the unit, students should be able to answer these core questions.

1. For conceptual benchmarks.
2. Bolded sections indicate portion of benchmark addressed
3. Unless noted as a Summative Assessment, the assessments are formative and should be used to guide teaching and learning.
