  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.

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
