08/07/14 Scientific Method: Putting It All Together INB P. 9 Sponge: Write and answer the following questions from the demonstration: P. 8 & 9: Give an example of an inference and prediction from the demonstration. An inference is when you explain something you observe. A prediction is a forecast of something to come. P. 7: 2. Give an example of a qualitative observation and a quantitative observation from the demonstration.. A qualitative observation deals with descriptions without numbers. Quantitative describes something using and amount.
Windows Notes: Draw the following Table under you sponge: INB P. 9 Write 3 facts from the video.Write 3 feelings you had while watching the video. Write 3 questions you had from the video. Write 3 ideas you had from the video.
Glue in your Scientific Method sheet on the right hand side of your notebook, page 10. Although we are reminding you now, this will be the standard procedure as we move forward. Start getting used to it… 8/07/14 Scientific Method: Putting It All Together INB P. 10
Let’s Read! Read the introductory passage about the scientific method and the characteristics of living things. Remember to use good reading strategies as you go through it! Afterwards, answer questions about the reading (1-8) on the inside of the sheet.
SpongeBob and his Bikini Bottom pals have been busy doing a little research. Read the description for each experiment and answer the following questions on your paper (right side)
Krusty Krabs Breath Mints Mr. Krabs created a secret ingredient for a breath mint that he thinks will “cure” the bad breath people get from eating crabby patties at the Krusty Krab. He asked 100 customers with a history of bad breath to try this new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a crabby patty. The other fifty (Group B) also received a breath mint after they finished the sandwich, however, it was just a regular breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the crabby patties, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating crabby patties.
1. Which people are in the control group? Group B – they ate the regular mint. 2. What is the independent variable? The type of mint. 3. What is the dependent variable? The number of people with bad breath. 4. What should Mr. Krab’s conclusion be? That his breath mint works. 30/50 people agree! 5. Why do you think 10 people in group B reported fresher breath? They were told that they had received the new mint. Their response may have been influenced by their emotions. Krusty Krabs Breath Mints
SpongeBob Clean Pants SpongeBob noticed that his favorite pants were not as clean as they used to be. His friend Sandy told him that he should try using Clean-O detergent, a new laundry soap she found at Sail-Mart. SpongeBob made sure to wash one pair of pants in plain water and another pair in water with the Clean-O detergent. After washing both pair of pants a total of three times, the pants washed in the Clean-O detergent did not appear to be any cleaner than the pants washed in plain water.
6.What was the problem SpongeBob wanted to investigate? How to clean his pants. 7.What is the independent variable? Whether or not he added laundry detergent. 8.What is the dependent variable? The cleanliness of the pants. 9.What should SpongeBob’s conclusion be? That the Clean-O detergent does not work any better than water. SpongeBob Clean Pants
15.Identify the following Control- Krusty’s usual itching powder Independent Variable- The type of itching powder Dependent Variable- The amount of time someone itches 16.Explain whether the data supports what the advertisements claim about the product. The advertisements are correct! They claim to cause 50% longer lasting itches than the usual powder. If the usual powder lasts 30 minutes, 50% of 30 is 15 minutes is 45 minutes of itching which is what the subjects reported
8/08/14 Fossil Footprints INB P. 11 Sponge: The story of Louis Pasteur. 1. Identify the hypothesis, independent variables, dependent variables, and the control group from the story. 2. How did Louis Pasteur develop his hypothesis and experiment?
8/08/14 Fossil Footprints INB P Hypothesis The virus infected the CNS. Independent variables-the amalgum of ground spinal cord. Dependent variables- Whether or not you get rabies. Control group- dogs 2. He observed the virus in saliva and victims went mad.
Glue in your Fossil Footprints sheet on the right hand side of your notebook, page 12. Although we are reminding you now, this will be the standard procedure as we move forward. Start getting used to it… 8/08/14 Fossil Footprints INB P. 12
Position One: Draw the footprints as you see them. 1. What do you observe about the size of the organisms? Can you infer the type of organisms they are? 2. Do you believe all the tracks were made at the same time? How do you know? 3. Can you infer how many organisms were involved in this picture? 4. Create a story that explains how these tracks got here. What do you think the organisms were doing while the tracks were being made?
Position Two: Draw the foot prints as you see them. 5. Did they change speed at any time? How can you tell? 6. What might have been the reason the footprint pattern changed? Was the land level or not? How can you tell? 7. What can you infer about the soil or type of rock when the tracks were made?
Position three: Draw the remaining footprints. Here is the full picture. Study this picture closely for one minute and then complete the assignment on the following slide.
So…. How did you use your skills of observation during this activity? Did your inferences differ from your classmates? Why is this?
Now that you’ve been given the entire picture, piece together your discoveries and describe what might have happened. You can either… Write a story: Use your answers for each position to tell a story about what happened to these organisms. Don’t forget to include an ending (this explains position 3). Describe the ending. OR Draw a comic book strip: If you chose this option, you must SHOW how the organisms ended up at their location, what happened to them while they were there, and show what the area looked like, basically answering the questions asked on the slides of positions 1 and 2.
08/15/13 Matter and Energy INB P. 13 in your INB Sponge: 1. What are the 3 forms of matter? Give an example of each found in nature. Solid-rock, liquid-water, gas-oxygen 2. What do you think happens to the energy of sunlight if it is never destroyed? The energy of sunlight is transformed from one form to another.
08/16/13 Characteristics of Living Things INB P How do you know that something is alive? If it has all four characteristics of living things. 2. Is a river alive? Explain. No, it doesn’t have all four characteristics of living things. 3. Is a tree alive? Explain. Yes, it has all four characteristics of living things.
Page 13 Left Side – write these notes under your bell work: 1. Water Helps organisms to: * Break down food * Grow * Move substances within their bodies * Reproduce
2. Food Used to get energy for life functions Autotrophs/Producers= plants Heterotrophs/Consumers= most animals * Carnivores- eat meat * Herbivores- eat plants * Omnivores- eat plants and animals
3. Space to live Place where they can get food, water, find shelter Organisms may compete for this space
4. Stable internal conditions Homeostasis- organisms need to maintain stable conditions inside their body * Temperature * Amount of water Allows cells to function properly
8/19/2013 The Characteristics & Needs of Living Things Foldable INB P. 17 Hmmm… what do I need? Sponge: 1. How are plants dependent on humans and how are humans dependent on plants? Plants depend on humans for carbon dioxide and we depend on plants for oxygen. 2.What is the most important source of energy for making food? Why? Sunlight is the most important source of energy for making food because it gives plants energy.
Characteristics of Living Things foldable pg. 18 What do we all have in common?
How to make your foldable: The Diamond 4 Door 1. Fold each corner of the square so that the opposite corners touch. When folded correctly, the paper will reveal an “X”. 2. Fold all of the corners of the square into the center of the X
On top of one flap, write these words: The Characteristics of Living Things Underneath the flap, write: “All living organisms share the following characteristics…”
Lastly, cut the remaining three flaps down the center (in this picture, on the dotted lines) toward the fold to reveal six smaller flaps. Now that you have created six flaps, you will write one characteristic under each one and draw what it looks like on the outside of the flap The Characteristics of Living Things Flap #2 Flap #3 Flap #4 Flap #1
Here’s an example of what it should look like:
Organized Structure: Flap # 1: Made of cells Unicellular Multicellular
Organized Structure: Flap # 2: Share similar chemicals DNA - nucleic acids Protein Lipids (fat) Carbohydrates - energy
Growth & Development: Flap # 3: Take in and use energy Move, think, make organs work Repair and replace cells Autotroph/Producer Heterotroph/Consumer
Flap # 4: Growth and Development Grow larger by cells multiplying in number Development is change (tadpole to frog)
Flap # 5: Reproduce Make offspring Sexually- mother and father Asexually- one parent (offspring is identical to parent- clone)
