# Science Skills Unit Part 4: Volume and Density

$9.99

This unit includes 5 lessons (50 minutes each) and 9 pages of printable work bundles. The Work Bundles have students fill-in critical notes, conduct exciting hands-on activities, answer questions, interpret graphs, includes games, built-in quizzes, and much more. The work bundles chronologically follow the detailed and interactive set of slideshows. A 10 question quiz game concludes for a great review and additional assessment. Answer Keys, materials list, built-in quizzes, and much more are provided. Everything you need to run a fantastic learning experience is provided. Everything arrives in editable format if you want add in your own slides and activities, and the slideshows and work bundles can easily be converted into Google Slides / docs for friendly Google Classroom learning.

This PowerPoint begins describing volume and the liter. A step by step slide sequence describes how a liter is made of 1000 ml. A slide describes how to measure volume in a graduated cylinder and describes how water forms a meniscus. A reference to measure at the bottom of the curve is made with visual. An activity has students fill containers with two different colored fluids and then mix them together. Students must fill one container with 500ml and the other with 100ml. How to find the volume of a cube is described in a step by step approach. L x W x H. Students then find the volume of various rectangles and cubes on the screen. For some the L, W, H are given. For others, students need to count boxes 1 cm each on all sides. How to find the volume of a cylinder is described in a step by step process with notes and visuals. A reference to PEMDAS is made but this rule is not covered in detail. A series of word problems with visuals and step by step answers show how to find the volume of a cylinder. An activity has the students measure a soda can. Students then learn how to find volume through water displacement with a couple visuals of a toy dinosaur being dropped in a graduated cylinder. Students can see the volume before the toy was placed in, and after. An activity slide has teacher gather several irregular shaped objects and students find the volume by water displacement. This is just framed for the teacher and teacher should find objects and supply water and measuring containers. Density is then described and the Mass divided by Volume explained. A picture of a Rubik's Cube is provided with mass and then students determine volume L X W X H. They use this data to then calculate density. Five popular Nintendo characters are then shown. Their mass and volume are presented. Students try and determine which one is most dense. The answers are revealed one at a time. A reference to which one would sink is made and answer revealed in visual form. Density and sink vs. float is described and a couple of challenge questions presented. An activity is then presented that has a student volunteer get submerged into a large trash barrel filled with warm water. Teacher must cut small hole near top of barrel and run a short length of hose so water can pour through. I run this activity outside but have done it inside bringing in a kid pool to surround the barrel just to be safe. Students weigh volunteer and then slowly dip them into water. Other students collect displaced water in large bucket and measure it. I like to use a 5 gallon bucket and just use a Sharpie Marker in advance to mark 10,000ml on the inside. Student volunteer continues to lower themselves as water pours through hose. Eventually student dunks head. I usually bring in a snorkel and mask for the student. Safety is addressed in the PowerPoint and reference to the student being allowed to breath freely at their leisure. Once no more water can be displaced students calculate the density of the student. This is an exciting PowerPoint that will involve and challenge your students.
