  2. Page 1 Lab Safety (5.1A, 5.4B): • Glued in Sponge Bob Lab Safety Challenge

  3. Page 2 Safety Rules (5.1A, 5.4B) • It is important to know and follow all the safety rules because you will be protected from injury, you will protect others from injury and you will avoid having too many accidents. • Safety foldable glued here.

  4. Page 3-4 Science Equipment / Tools (5.4A) • Foldables of the tools, their picture, and their definition. Compass-used to find directions Ruler-used for linear (length) measurement of objects – centimeter, millimeter Stopwatch- used to measure time during an investigation Apron-used to protect skin and clothing. Collection net-used to collect live specimens Pipette-used to transport a very small amount of liquid Petri dish-small, round, clear dish used to hold objects

  5. Page 5 Scientific Method (5.3AB, 5.2ABCDEF)) • Students wrote a Lab Report using the Scientific Method. • This page shows and explains what is expected in a Lab Report.

  6. Page 6 Scientific Method Vocabulary (5.2ABCDEF) • Investigation: the search for an answer to a question • Hypothesis: an educated guess about an investigation that can be tested • Data: the info collected during an investigation • Conclusion: an explanation based on your observation or measurement • Inference: an explanation based on what you already know or what you have seen • Direct evidence: evidence that comes from measurements, tests, or observations • Indirect evidence: evidence based on an inference • Variable: a factor that can change in an experiment • Procedure: a planned set of steps • Trial: a repeat of an observation or test

  7. Page 7 Tables, Graphs, Charts (5.2G) • Graph: a drawing that shows how two or more types of data are related. • Table: data presented in rows and columns. • Chart: a picture that uses symbols to represent data. • We drew examples of each one.

  8. Page 8 LAB (5.3AB) • Airplane Noses • Problem: Which paper airplane will fly the furthest, a pointed nose or a blunt nose? • Hypothesis: If a real plane has a pointed nose to cut through the air, then a pointed nose paper plane should cut through the air too, and go further. • Materials: • 2 pieces of printer paper • 2 pieces of tape • Science NB • pencil • Procedures: • 1. Fold 1 piece of paper into a plane with a pointed nose and tape it. • 2. Fold another piece of paper into a plane with a blunt nose and tape it. • 3. Throw each plane and record which plane went further. • 4. Repeat step 3, two more times. • 5. Record data. • Data: • Conclusion: • The hypothesis was rejected/accepted. The hypothesis stated that, if a plane has a pointed nose to cut through the air, then a pointed nose to cut through the air, then a pointed paper plane should cut through the air too, and go further. Two paper planes were made and thrown 3 times with the furthest one getting recorded each time. During the trials, the blunt/pointed went further.

  9. Page 9 LAB measurement (5.4A) • Lab data is recorded here.

  10. Page 10 LAB Variables (5.4) • Variable: the one thing that is changed in an investigation. • Constant(s): those things that remain the same in an investigation. • Lab data is recorded on this page.

  11. Page 11 Matter Vocabulary (5.5A) • Matter: stuff that everything is made of • Mass: the amount of matter in an object (amount of space it takes up) • Physical properties of matter: mass (weight), magnetic, physical state (solid, liquid, gas), relative density, solubility, ability to insulate or conduct electricity or heat • Magnetism: being attracted to a magnet • Physical state of matter: solid, liquid, gas • Relative density: objects that are more dense – sink in water / objects that are less dense – float in water • Solubility: measurement of the ability to dissolve in a liquid • Solute: dissolves • Solvent: does the dissolving • Classify: group together based on similar traits

  12. Page 12 • Thermal energy: energy that causes a change in temperature between materials. • Electric energy: energy produced by movement of electrons. • Conductor: materials that allow electric current or heat energy to flow through easily. • Insulator: material that slows down or stops electric current or heat from flowing • Matter Classification foldable glued on back. • Mass • Physical state • Magnetic • Solubility • Conductivity • Relative density www.studyjams.com Properties of Matter video and quiz Solid, Liquid, Gas video and quiz

  13. Page 13 States of Matter (review from 4th) (5.5A) • Solid, Liquid, Gas foldable glued here.

  14. Page 14 How Temperature changes matter: water (5.5B)

  15. Page 15 Changes in Matter (5.5B, 3.5C) • Matter can change states when adding or taking away heat (energy). Cut and paste activity attached here…completed as a class.

  16. Page 16 Hot Air Balloon Problem: Can melting ice blow up a balloon? Hypothesis: If ice is heated and melts into a liquid, and the liquid is heated and changes into a gas which takes up space in a container, then ice can blow up a balloon. Materials: 1 balloon 1 hot plate 1 flask 12 ice cubes 1 oven mitt Procedures: • Heat the hot plate • Place 4 ice cubes into the flask • Stretch the mouth of a balloon across the mouth of the flask • Set flask on hot plate • Observe and record data • Repeat steps 1-5, 2 more times

  17. Page 16 back Data: x = confirmation Conclusion: The hypothesis was accepted. The hypothesis stated, if ice is heated and melts into a liquid, and the liquid is heated and changes into a gas which takes up space in a container, then ice can blow up a balloon. An investigation was conducted by placing ice into a flask with a balloon over the mouth of the flask and set on a hot plate and observed. The results of the investigation showed that once the ice melts, completely and reaches the gas state, it did indeed fill up the balloon.

  19. Page 18 Volume LAB sheet (glued on front) (5.5A) Density LAB Demo (drawn on back) The most dense liquid is honey. The least dense liquid is rubbing alcohol. A lower density liquid will float On top of a higher density liquid. Ex. Salad dressing (oil,vinegar,water), ketchup, mustard. www.stevespangler.com Density video
