Scientists use supporting evidence to create an explanation. Explain why using evidence to support your explanations is a good p

lesya [120]

Answer: Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work. Inquiry also refers to the activities of students in which they develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study the natural world. National Science Education Standards, p. 23.

As pointed out in the National Science Education Standards (National Research Council, 1996), students who use inquiry to learn science engage in many of the same activities and thinking processes as scientists who are seeking to expand human knowledge of the natural world. Yet the activities and thinking processes used by scientists are not always familiar to the educator seeking to introduce inquiry into the classroom. By describing inquiry in both science and in classrooms, this volume explores the many facets of inquiry in science education. Through examples and discussion, it shows how students and teachers can use inquiry to learn how to do science, learn about the nature of science, and learn science content.

A good way to begin this investigation is to compare the methods and thinking process of a practicing scientist with the activities of an inquiry-based science lesson. The stories in this chapter set the stage for many of the themes to follow. The sidebars suggest some important aspects of the investigations of both scientists and students.

mr.mcbride asks students to find the volume of the triangular pyramid below. which student wrote the correct expression for the

Black_prince [1.1K]

<u>Given</u>:

Given that the height of the pyramid is 20 inches.

The sides of the triangle are 9 in, 12 in and 15 in.

The expression for the area of the base written by JO is $\frac{1}{2}(9 \cdot 15)$

The expression for the area of the base written by MAE is $\frac{1}{2}(9 \cdot 12)$

We need to determine the correct expression for the area of the base written by the student.

<u>Expression for the area of the base:</u>

The area of the base of the triangular prism can be determined using the formula,

$B=\frac{1}{2}bh$

where b is the base of the triangle and h is the height of the triangle.

From the figure, the base of the triangle is 9 inches and the height of the triangle is 12 inches.

Substituting in the above formula, we get;

$B=\frac{1}{2}(9 \cdot 12)$

Thus, the correct expression for the area of the base is $B=\frac{1}{2}(9 \cdot 12)$

Hence, the expression wrote by MAE is correct.
