Cells cells they're made of organelles song lyrics Cells song: Using song to help students learn science is a powerful tool. Below are some songs which help students learn about cells. My research indicates that the songs should be played more than once. I give students a copy of the lyrics to glue in their science notebook. The songs are on YOUTUBE and have videos as well.

Six Kingdoms Coloring Worksheet - six kingdoms coloring worksheet answer key Directions: Read the following and then answer the questions by coloring the picture on the back. Your answers will be shown by how you color. Traditionally, living things were divided into two kingdoms, plants and animals. As the science of biology continues to develop, we have come to realize that two kingdoms are not enough for all organisms to fit into. For example, there is a single-celled organism called Euglena. This organism has some characteristics of a plant and some characteristics of an animal. As time went on, other organisms were discovered with weird traits that made them difficult to classify as either plant or animal. Most scientists agree that it makes sense to divide living things into six kingdoms. Remember, though, that kingdoms are purely human inventions. No other living organism, as far as we can tell, cares a bit what kingdom it is in. As the future of biology unfolds, we may see evidence for division into more than six kingdoms. (Various biologists have already suggested seven and eight kingdoms.) Kingdom Archaebacteria This kingdom includes bacteria and interesting little creatures called cyanophytes, also called blue-green algae. They are unicellular (single-celled) and prokaryotic, meaning that there is no nucleus inside the cell. Most biologists believe that the first living things on earth were probably similar to today’s bacteria. Another cool thing about this group of organisms is that they are adapted to almost any type of environment, even if it is extreme by our standards (hot, cold, salty, etc.) Bacteria are just about everywhere on Earth
