*Health class Healthy Eating worksheet (Make a copy for yourself and fill out the worksheet)
All of our Pure Substances & Mixtures unit resources will be posted here and broken down into 3 sub units; Classifying matter, Solutions, and Separating Mixtures. Any extras (Could do’s) are located at the bottom of the page.
1.1 – What is Matter? (Make a copy of all student textbook pages and add them to your Chemistry Folder)
1.2 – More About Matter (After adding to your Chemistry folder, read and answer questions #1 -4)
On Tuesday October 12th, Science classes participated in the Global Maker Day. A day dedicated to learn, share, and play while completing STEM related challenges. Challenges will provide students to practice problem solving, be creative, and have fun learning.
Possible events, presentations, videos and challenges are listed below.
Here are some helpful tips as you expand on your web literacy, research, and digital citizenship skills. Feel free to download a copy and add it to your Science folder to refer back to it when needed. Review Sheet found below.
Unicellular organisms are composed of a single cell, unlike multicellular organisms that are made of many cells. This means that they each live and carry out all of their life processes as one single cell. Most unicellular organisms are microscopic;
Also called microorganismsor microbes since they are only visible under a microscope.
The single cell is responsible for feeding, digestion, excretion and reproduction.
Some microorganisms make us sick, but without the others we could not survive.
The following are examples of unicellular organisms:
Multicellular Organisms Defined:
A tissue, organ or organismthat is made up of many cells is said to be multicellular. Animals, plants, and fungi are multicellular organisms and often, there is specialization of different cells for various functions. In contrast, unicellular, or single-celled organisms are much smaller in size and less complex as they are composed of just one cell that senses its environment, gathers nutrients and reproduces asexually. The following are examples of multicellular organisms: human beings, organs and tissues, plants, animals, birds and insects.
~Generally speaking, we can say that unicellular and multicellular organisms are alike in that they exhibit all the functions of life, such as metabolism and reproduction, they contain DNA and RNA, they can exhibit a wide range of lifestyles, and they are essential to almost every ecosystem that we currently know of.
Amoeba, Euglena, Paramecium on the move
The paramecium are the larger protists, amoeba are the blob-like protists, and euglena are the smaller unicellular organisms.
