Slide #1 Trinidad and Nidia

1. Slide #1Trinidad and Nidia • A variable is something that is different in an experiment. • You only want to test one variable at a time. -Mix Dry

2. #1 SahilAmin A variable is something in an experiment. You only want to test one variable in an experiment Dry Mix

3. Slide #2Xenia and Brenda • Be safe when working in a lab! Listen to instructions and don’t touch anything without permission. • Example: don't eat , play around…

4. #2Adrian Beltran Always listen to the teachers instructions before beginning. If not cautious you might hurt yourself.

5. Slide# 3Vanessa & Noah • Contour Lines- They Show elevation. Contour lines that are close together represent a Steep Slope. Contour lines that are Far apart represent a Gentle Slope.

6. Volume Volume = length x width x height Slide 4 Jamie Chan Height You can find volume by measuring how much the water changes when you add a object. Length Width Volume is the amount of space that an object takes up.

7. Slide 5: Graduated cylinders Hailey Towery , Emily Carson • Graduated cylinders and beakers can be used to measure volume.

8. #5 KaitlynEtie + Graduated cylinders and beakers can be used to measure volume. For a graduated cylinder, read the bottom of the meniscus.

9. A problem is a question. Slide 6Shelby Fisher A hypothesis is an educated guess. A conclusion is an answer.

10. Bar graph Line graph Used to organize data FAQ#7GRAPHS Pie graph Compare data Used to compare data over time Andrew Flores Per.1 Compare parts of a whole

11. Denser objects in water will SINK, while the objects with smaller densities will float on TOP of the water. Larry Guan <08>

12. Slide #9 KaramKassem In order for a scientific explanation to be credible, it must be repeated over and over and only one variable can be tested at a time. For a scientific explanation You don’t do it once not twice but three times.

13. Slide number 10 :Hank kelley The purpose of using a model is to show something to small or to big

14. DNA contains all genetic information and is found in the nucleus of cells. DNA is inherited through sex cells such as sperm and egg Slide #11 Ian Lanier

15. Andrew Laurel <12> Asexual & Sexual Reproduction Asexual reproduction deals with one parent that separate and look identical to the parent, humans do not reproduce this way. Sexual reproduction deals with two parents that mate with each other and have offspring that do not look identical to parents they have characteristics of both parents, humans reproduce this way.

16. Slide #13 All living things are made of cells Cells Populations EmmaMaduta Tissues Organisms Organs Organ Systems

17. Homeostasis is the keeping of a persons internal balance like when you are hot you sweat to cool down. Fact 15 Homeostasis Shane McCleskey Per.1

18. Ecological Succession Primary and Secondary Succession Jacob McEwen[16] Ecological Succession is a series of changes in an ecosystem. Drastic events like forest fires or climate changes can trigger secondary succession. When new land forms, perhaps from a volcanic eruption, primary succession may occur.

19. Slide #17 Traits that you get from your parents are called inherited traits. Both animals and plants inherit traits. Humans inherit eye color but not hair length. Plants inherit flower color. Designed by: HayleeMunsinger

20. Slide#18 KevinNgo (; Period 1 A a AA (25%) Aa Punnett Squares (25%) A Aa aa (25%) (25%) a Each box has a 25% chance of happening. Uppercase letters = Dominant traits Lower case letters = Recessive traits

21. Slide #20 Brandon OAdaptive characteristics Adaptive Characteristics are things that help something survive. (Darwin’s idea of natural selection) Examples: jackrabbits have long legs for escaping predators. Cactus can hold a great deal of water

22. Slide #21Mohammad Siddiqi Environmental changes such as a lack or oxygen, water or food supplies can cause living things to become ill or die. When food, water or oxygen is plentiful, it can cause living things to thrive. Animals adapt in order to survive in an ecosystem.

23. Slide 22Crystal Silva Period 1Mrs. vidiola A food web shows energy being transferred in a habitat. The plants are the producers, the animals that eat the plants or other animals are the consumers, the animals that hunt consumers are the predators and the things that eat dead or decaying objects are decomposers. Arrows show flow of energy.

24. #23Bryce Smarr The source of all life is the sun. Without it, there could be no plants and therefore no animals. Almost ALL energy originates with the sun

25. Slide #24 • Physical Properties tell you all about an object. • It lets you know if they are – • Magnetic • A solid • A liquid • A gas • And whether or not they are a conductor of electricity, heat, and sound. Lexi Valdes

26. The Law of Conservation of Mass says matter is neither gained nor destroyed. The mass of reactants=mass of products Slide #25 Beverly Wooten = Number of atoms of reactants=Number of atoms of products Reactants=Products =

27. Slide #27Jabria Ard & Lesley Bazan Exothermic reactions release heat (feel hot) and endothermic reactions absorb heat (feel cold)

28. Fact Number 29Kyle Bailey & Elena Cosme Chemical reactions create new substances with new properties. Ex. Iron Rusting http://ts3.mm.bing.net/th?id=H.5022999520936010&pid=1.7&w=260&h=145&c=7&rs= http://ts3.mm.bing.net/th?id=H.5022999520936010&pid=1.7&w=260&h=145&c=7&rs=

29. Slide #30Johnny F. and Amaru G. • Compounds are made of multiple elements • Elements are pure (contain one kind of substance)

30. Slide #31Emily Hale and Noah Haynes • The smallest part of a compound is a molecule. The smallest part of an element is an atom.

31. Slide #32Kenia & Clayton Atoms are made up of 3 particles. Protons have a positive charge and are found in the nucleus. Neutrons do not have a charge and are found in the nucleus. Electrons Have a negative charge and are outside the nucleus in the electron cloud.

32. Slide #33 Protons and electrons • Electron are equal to atomic number Neutons equal atomic mass.

33. Slide # 34Julianna LozanoGabby Newton • A mixture occurs when two or more pure substances are mixed together. To separate a mixture you must look at the substances physical features in order to decide how to separate it. If one of the objects is magnetic, you can separate it with a magnet. If one of the objects is dissolved in a liquid, you can use evaporation to separate it.

34. #35by Keegan Paaske & Alex Rodriguez When you dissolve something in water, like sugar, the sugar breaks down into very tiny pieces. While it dissolved, it no longer behaves like a solid, but instead like a liquid. When you separate the mixture through evaporation, the sugar is once again a solid. Dissolving is a MIUXTURE.

35. Side #36Tatiana RogersAlberto Ugueto • Friction occurs when objects rub against each other. Low friction is when things slide easily, like a water slide.

36. #38Josh Adeokun & Maddison Albright • Deposition- It is the deposit of sediment over a period of time. Deltas are formed by deposition. Also, sedimentary rock layers, like those seen in the Grand Canyon are the result of deposition.

37. Slide #38Rhylee Azevedo • Deposition is the deposit of sediment over a period of time. Deltas are formed because of deposition. Also, sedimentary rock layers, like those seen in the Grand Canyon are the result of deposition.

38. #39Scott Bazemore • Weathering- The breaking up of large rocks into smaller rocks. Weathering occurs over millions of years. There are two types of weathering.

39. Slide # 40Ja’Brea Bennett • Erosion- is the movement of weathered material.

40. Slide #41Jacob Bruce • Renewable Resources can be replaced • Ex: Planting a tree

41. #42John Cato • Nonrenewable Resources, like fossil fuels, cannot be replaced or renewed

42. Slide #43Angel Chui • Inexhaustible resources get used over and over, they do not run out.

43. #44Joshua Garcia • When the earth turns around once on its axis(rotates),a day occurs

44. Slide #45Talia Guzman • When the moon revolves once around the Earth, a month occurs.

45. Slide# 46Gabrielle Holder • When the Earth revolves once around the sun ,a year occurs. (rev.ol.u.tion 4 syllables… 4 seasons)

46. Slide #48Graciela Martinez The water cycle includes evaporation, condensation, and precipitation. If one step is removed, the cycle will not work.

47. Slide 49By Haley Moquin • Cycles have no beginning and no end. They go round and round.

48. Slide # 50Julia Nettles • The Nitrogen Cycle puts nitrates into the soil for plants to use.

50. Slide #51Natasha Nguyenphat • The carbon-dioxide/oxygen cycle produces oxygen for us to breathe • Plants take in carbon dioxide and give off oxygen
