2. Warm up Define: Crest Trough Wavelength Amplitude –. The top of a transverse wave The bottom of a transverse wave The distance between crest to crest or between trough to trough The power or energy of a wave

3. Conductors are metals that transfer energy easily. Vanishing Content

4. A disturbance is another name for a force.

5. Interactive Notebook You will be in different stations in groups doing different things. There will be a procedure for you to follow at each station. Don’t forget to: > Write date on the title page > Place title in TOC

6. The stations Metal stations.

7. Vanishing Content A transverse wave’s energy moves perpendicular to the force which caused it to move.

8. Vanishing Content Frequency is the number of times a wave cycles in a second.

9. Vanishing Concept Pitch or note is determined by frequency.

10. How are the two waves different and how are they the same? longitudinal wave and transverse wave. Describe where the compressions are. Describe where the rarefactions are.

11. Vanishing Content An earthquake primary (P) wave is a longitudinal wave

12. Vanishing Content An earthquake secondary (S) wave is a transverse wave.

13. INTERACTIVE NOTEBOOK TITLE: WAVE PROPERTRIES Put date on title page Fill out that TOC

14. Poster time Observer the post. Tell your partner what you think the poster is trying to teach you.

15. Wave Properties Amplitude – This is the energy of the wave. The bigger the amplitude the more energy the wave has. Wavelength – The distance from crest to crest or trough to trough. Frequency – the speed of the wave The number waves passing a fixed point in a certain amount time

16. Test today on waves Where is the crest? Describe the crest in words. Where is the trough? Describe the trough in words What do call the measurement from the crest of one wave to the crest of the next wave? crest trough Wavelength What is the distance between two adjacent crest or troughs on a wave? Wavelength Short review

17. 2.Interference – when two waves collide. a) constructive interference In phase = Constructive interference happens when two waves are in phase to add to make one big wave. Waves Strengthen each other

18. b) Destructive Interference Out of phase (overlap) = Destructive interference happens when two wave are out of phase and cancel each other out. Waves cancel each other

19. Time for test

Atoms Letters Elements Words Molecules Sentences Compounds Paragraphs Materials Novels go to table H 2, H2OH2O Chemistry Language Arts Atom -- the smallest part of an element The basic part of all matter Compare and contrast chemistry to language arts Write a paragraph that compares and contrasts chemistry to language arts Homework

21. Warm Up Draw a transverse wave and label the crest, wavelength

22. Vanishing Concepts Temperature describes the movement of the particles. The direction of heat is from warmer objects to cooler objects.

23. Summarize this writing The word ecosystem is short for ecological systems. An ecosystem includes all of the living organisms in a specific area. These systems are the plants and animals (biotic) interacting with their non-living environments - biotic (weather, Earth, Sun, soil, atmosphere). An ecosystem's development depends on the energy that moves in and out of that system. As far as the boundaries of an ecosystem, it depends upon how you use the term. You could have an entire ecosystem underneath a big rock. On the other hand, you could be talking about the overall ecosystem of the entire planet (biosphere).

24. Summarize this writing An ecosystem includes the living (biotic) and nonliving (biotic) parts, plus the energy that moves within it. It can be small or large.

25. Vanishing Concepts The new moon is the lunar phase describing an absence of the moon Each lunar cycle starts and ends with the new moon. The waxing phase indicates that moon appears to grow.

28. Why plants have leaves Leaves make food for the plant. Sum up the thought, but keep the meaning of the paragraph.

29. Why plants have leaves Leaves make food for the plant. The sun shines on each leaf.

30. Why plants have leaves All the green parts of the plant make food for the plant. The sun shines on each leaf. Sunlight gives the leaf energy to make the food. The food is made from water, soil and carbon dioxide. This is called photosynthesis. Sum up the thought, but keep the meaning of the paragraph. 41

31. Why plants have leaves Leaves make food for the plant. The sun shines on each leaf. Sunlight gives the leaf energy to make the food. The food is made from water, soil and carbon dioxide. Leaves make food using Sunlight with the help of water, soil and carbon dioxide. This is photosynthesis 31 17

32. Why do plants have roots? All plants with flowers have roots.

33. Why do plants have roots? Plants have roots for two main reasons. 1)Roots anchor the plant in the soil, and prevent it from being blown away by strong winds. 2)Roots also take up water and minerals, such as nitrogen and sulfur, from the soil. Plants need water to replace that lost by transpiration, and minerals to make substances for life. Bactria in soil help the plant take up nitrogen, minerals and sulfur in the rooms
