3. Work on your labs. Get it done…if labs are LATE…you don’t get a chance to correct conclusion

4. 1. Opener: 2. Review of Length Lab 3. Notes: 1. Measurement 1.Volume 4. Activity: 1. Volume Activity—We will finish this on Tuesday if needed! 5. Homework: 1. Questions from TEXTBOOK: 2. Page 17 in your textbook.

5. 1. Why is the scientific method important when doing experiments.

7.  You need to know the vocabulary:  Control  Independent  Dependent  Constant  Qualitative  Quantitative  Know the steps of the scientific method…  Review the notes 5 minutes every night…maybe not even 5 minutes needed to do this…  DO YOUR BEST!

8. Metric Units Volume is the amount of space an object takes up. The base unit of volume in the metric system in the liter and is represented by L or l. Standard: 1 liter is equal to one cubic decimeter Metric Units 1 liter (L) = 1000 milliliters (mL) 1 milliliter (mL) = 1 cm 3 (or cc) = 1 gram* Which is larger? A. 1 liter or 1500 milliliters B. 200 milliliters or 1.2 liters C. 12 cm 3 or 1.2 milliliters* Click the image to watch a short video about volume. * When referring to water Liter Image: http://www.dmturner.org/Teacher/Pictures/liter.gif

Measuring Volume Top Image: http://www.tea.state.tx.us/student.assessment/resources/online/2006/grade8/science/images/20graphicaa.gif Bottom Image: http://morrisonlabs.com/meniscus.htm We will be using graduated cylinders to find the volume of liquids and other objects. Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water. What is the volume of water in the cylinder? _____mL What causes the meniscus? A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides.

10. Measuring Liquid Volume Images created at http://www.standards.dfes.gov.uk/primaryframework/downloads/SWF/measuring_cylinder.swf What is the volume of water in each cylinder? Pay attention to the scales for each cylinder.

Choose Lessons  Volume & Displacement 10 cm 9 cm 8 cm We can measure the volume of regular object using the formula length x width x height. _____ X _____ X _____ = _____ http://resources.edb.gov.hk/~s1sci/R_S1Science/sp/e n/syllabus/unit14/new/testingmain1.htm We can measure the volume of irregular object using water displacement. Amount of H 2 O with object = ______ About of H 2 O without object = ______ Difference = Volume = ______

13.  Textbook Questions: ▪ This will go on the back (even page) ▪ Title it: 1.2 Questions  This is found on p. 17  Please write the questions  Do numbers 3-8

15.  A farmer wants to know how he can increase milk production by his cows. He allows the cows to graze more than normal and gives them a vitamin supplement weekly. What is the main problem with this investigation?  Purpose: If you have 2 fish and one swims in a tank next to a window and one in a dark room, which one will grow faster?  Write a hypothesis using the correct form, 1 point

16. 1. Understand the IN and its uses 2. Explain the steps of the scientific method and apply it to real- life situations 3. Design a simple experiment.

17. 1. Opener: 1. Vocabulary 2. Notes: 1. Mass Notes 3. Activity: 1. Mass Activity 4. Homework: 1. Special Assignment

18. Metric Units Mass refers to the amount of matter in an object. The base unit of mass in the metric system in the kilogram and is represented by kg. Standard: 1 kilogram is equal to the mass of the International Prototype Kilogram (IPK), a platinum-iridium cylinder kept by the BIPM at Sèvres, France. Metric Units 1 Kilogram (km) = 1000 Grams (g) 1 Gram (g) = 1000 Milligrams (mg) Which is larger? A. 1 kilogram or 1500 grams B. 1200 milligrams or 1 gram C. 12 milligrams or 12 kilograms D. 4 kilograms or 4500 grams Click the image to watch a short video about mass.

Measuring Mass Top Image: http://www.southwestscales.com/Ohaus_Triple_Beam_750-SO.jpg Bottom Image: http://www.regentsprep.org/Regents/biology/units/laboratory/graphics/triplebeambalance.jpg We will be using triple-beam balances to find the mass of various objects. The objects are placed on the scale and then you move the weights on the beams until you get the lines on the right-side of the scale to match up. Once you have balanced the scale, you add up the amounts on each beam to find the total mass. What would be the mass of the object measured in the picture? _______ + ______ + _______ = ________ g

20. Measuring Mass – Triple-Beam Balance Click here to try an online activity. 1 st – Place the film canister on the scale. 2 nd – Slide the large weight to the right until the arm drops below the line. Move the rider back one groove. Make sure it “ locks ” into place. 3 rd – Repeat this process with the top weight. When the arm moves below the line, back it up one groove. 4 th – Slide the small weight on the front beam until the lines match up. 5 th – Add the amounts on each beam to find the total mass to the nearest tenth of a gram.

21. Mass Worksheet: Complete; you may write on worksheet

22.  Using your notes, define these terms:  Independent variable  Dependent variable  Abbey wants to determine how long it takes for a tadpole to develop into a frog. IN what order should she do the following steps? W. Obtain frog eggs X. Write a report on her findings Y. Predict how long it will take for a tadpole to develop into a frog Z. Observe the frog eggs every day and record changes that take place as the eggs hatch and the tadpoles develop
