Science Homework / classwork

Nov. 12 - 20

This week we will begin to study density. (D=m/V). students will look at properties of density . We will be creating density layers in liquids.

The week begins with a quick review of 'atoms and molecules' followed by explorations into states of matter. Later in the week we will look at 'Cartesian Divers' . The week will wind down with

Lesson Goal: The purpose of this lesson se is to introduce students to the concepts of density, mass and volume and prepare them to complete a performance task in which they must use their knowledge of these concepts.

Concepts to be developed:

1. Density is the measurement of the compactness of an object. 2. Density is a property that is determined by the ratio of a substance’s mass to its volume. 3. Mass is how much matter is inside of an object. 4. Volume is how much space something takes up.

Skills to be developed:

1. Students will use a balance to measure mass. 2. Students will describe a scientific concept in writing using their own words. 3. Students will use logic and scientific guessing to find objects of the same mass.

Objectives:

1. Students will describe the concepts of mass and volume in a letter. 2. Students will calculate the mass of objects using a balance. 3. Students will use scientific reasoning to find two objects with identical masses. 4. Students will measure and record objects that have identical masses, but different volumes. 5. Students will observe objects that have identical volumes, but different masses.

October 29- Nov. 2

The seventh grade will continue to work on Newton's Laws. On Monday the classwork involved an independent exploration of Newton's Third Law. The website https://www.ck12.org/c/physical-science/newtons-third-law/

Was used which allows students to work at their own pace.

Tuesday and Wednesday we will be watching a slightly edited version of the movie 'Gravity' . The students will be looking for errors where the film -makers failed to follow Newton's Laws.

Thursday should find us finishing with the video with a short discussion and even shorter assessment.

friday will be a hands-on day exploring and playing with Newton's Laws.

Sept. 17-21

This week we will be writing an opening paragraph in order to develop the skills to write a science report. The paragraph will be used as part of a project to create a Public Service Announcement design ed using a computer.

Sept. 13 The new school year is always an exciting time for me. I enjoy meeting new students and preparing for the great learning that lies ahead.

We started the year with a short 'mini-unit' about the Scientific Method and the use of some of the science equipment. This lead us into our first full unit 'Survival' in which we will learn what it takes for an organism to survive with a focus on endangered species. Each student will choose their own animal to research.

Attached is the assignment sheet for the survival unit. Home will be needed for students unable to complete the assignment in class. https://docs.google.com/document/d/1lnzhjEdFK4Wl41MraSEQzj5JX9amrFGb85wSb3RkQsc/edit?pli=1
