How does Earth's surface change quickly? What is conservation of mass? What are the states of water? What are Newton's Laws?
The Spectacular Scientists can answer these questions!
Third Grade:
The third grade scientists studied quick changes to Earth's surface: earthquakes, volcanoes, floods, and mudslides. They explained how fires, landslides, and floods affect living things, described how volcanoes, earthquakes, floods, and landslides can affect Earth's surface, explained what causes earthquakes and volcanic eruptions, and created emergency/disaster relief lists and kits. They researched "superlative disasters": the worst floods, fires, earthquakes, and volcano eruptions on record and found that "worst disaster ever" can be determined by destruction to land and property or by human injuries and fatalities. The third grade scientists agree that any dramatic, catastrophic event is "the worst ever" as each event causes damage and loss. We discussed earthquake, volcano, landslide, and fire safety procedures and designed emergency lists and kits. The students completed the end-of-unit review and evaluations. Next week will be a very busy week! We will complete landform projects, conduct a plate tectonic investigation, and set up displays for our Spectacular Science 3-4-5 Museum.
Fourth Grade:
The fourth grade scientists used pan balances to illustrate the law of conservation of mass: Matter cannot be created or destroyed. Matter can be changed into a new form; the new form will have the same amount of mass as the old form. The students measured the mass of 4 Lego blocks, then separated the blocks into groups of 3 and 1, 2 and 2, and as individual blocks. The students compared the total mass of each new combination: 3 and 1, 2 and 2, and 4 individual blocks, to the mass of the 4 linked blocks. According to the law of conservation of mass, the 3 and 1, 2 and 2, and 4 individual block masses should be the same as the 4 linked blocks. Some groups had different findings. We discussed our results and discovered that discrepancies occurred due to errors made measuring mass and calculating total mass. The students also studied states of water and states of matter. They described the 3 states of water and 3 states of matter, explained how heating and cooling change the states of matter, and explained how matter isn't lost or gained as it changes states. The students completed their end-of-unit review and evaluations. Next week will be a very busy week! We will complete properties of matter projects, conduct a physical change vs. chemical change experiment, and set up displays for our Spectacular Science 3-4-5 Museum.
Fifth Grade:
The fifth grade scientists studied Newton's laws of motion. They explained the laws of motion, described and identified inertia, and related motion in space to the lack of gravity in orbit around Earth. Newton's first law of motion states that no acceleration can happen without an unbalanced force; this describes inertia. Inertia is the tendency of objects to resist a change in motion. Newton's second law states that an object's acceleration depends on two factors - the amount of force applied to the object, and the object's mass. Newton's third law states that forces always act in pairs. The students conducted scientific investigations to test and demonstrate each law. The students completed the end-of-unit review and evaluations. Next week will be a very busy week! We will complete forces and motion projects, conduct investigations to demonstrate and test laws of force and motion, and set up displays for our Spectacular Science 3-4-5 Museum.
A SPECTACULAR SCIENCE MUSEUM!
The Spectacular 3rd, 4th, and 5th grade scientists are creating an interactive science museum. The 3rd graders will display engineering and Earth science projects and demonstrate and instruct Earth science investigations. The 4th graders will display life science and engineering projects and demonstrate and instruct states of matter and conservation of mass investigations. The 5th graders will display life science and physical science projects and demonstrate and instruct force and motion investigations. The Spectacular Science 3-4-5 Museum will be open Thursday, May 28 from 12:10-1:00 (4th grade presentations) 1:10-1:45 (3rd grade presentations) and 3:15-3:55 (5th grade presentations. We would love to have you visit our museum! Please contact Mrs. Lerner -via email- to arrange a visit.
