 * Sink or Float? || 1st grading period || (1) What is buoyancy?

__Key Vocabulary__: buoyancy, float, sink, material, shape, size, weight, surface tension, balance, capacity, cargo || (1) Test the buoyancy of objects made of different materials and record results. (2) Infer the factors that determine whether objects will sink or float. (type of material, size, different liquids, weight) (3) Discover that buoyancy can be changed by changing an object's shape. (4) Use a balance to determine weight. (5) Observe that buoyancy of an object is different in different liquids by conducting experiments. (6) Design clay boats that will float and carry weight without sinking. || (1) "Sink or Float" student books (2) "Sink or Float" class chart (3) online texts and activities (4) PowerPoint presentation on surface tension || * Online activities (1) What Sinks, What Floats? (2) Same Size, Same Shape (3) Different Size, Same Shape (4) Bubbles and Buoyancy (5) Same Size, Different Shape (6) Floating Metal (7) Fresh and Salty (8) Boats of all Shapes

GLE 0207.6.1 Realize that the sun is our nearest 0207.6.1 Observe and collect data on the star and that its position in the sky appears to change. sun’s position at different times of the day. || Expo || 4th Quarter || Questions: (1) How do scientists find out about objects, living things, and events? (2) What tools, skills, and knowledge are needed to conduct scientific inquiry? || Concepts: (1) Observe familiar objects using the senses and tools. (2) Ask questions, make logical predictions, plan investigations, and represent data. (3) Interpret and create bar graphs. (4) Explain the data from an investigation.
 * Standards Addressed:**
 * Science

__Key Vocabulary__: method, hypothesis, prediction, experiment, results/data, graph, conclusion || Skills: (1) Use senses and simple tools to make observations. (2) Plan for simple investigations. (3) Communicate the understanding of simple data. (4) Collect, discuss, and communicate findings from a variety of investigations. (5) Design and conduct a class investigation. || Texts: 1) PowerPoint presentation on Scientific Method for Young Kids (2) online supportive texts and activities || www.sciencebuddies.org

Online activities *Experiments/Activities: (1) Which paper airplane design will fly the furthest distance? (Steps of scientific method) (2) Create a human bar graph using post-it notes and a class pie chart to show the same data. (3) Graph results of the paper airplane experiment. (4) Online graphing [|site]: (Airplane and How Many Teeth have you Lost graphing activities) (5) Students choose a science question to investigate, and follow the steps of the scientific method. (Examples: What liquid is best for cleaning old pennies? Does the shape of a bubble wand affect the shape of a bubble? Will a coat keep a snowman from melting?) This will lead to deciding the topic of our class science fair project and following the steps of the scientific method to complete it.

Standards Addressed:** ||
