= = =Can you add a fun fact you know or tell us about an activity you tried? =

1. Bacteria can be good or bad. Is this a true fact? What do you think? JT: I think true CB:Yes, it can be good because you need some bacteria in your body so you can survive. Yes, it can also be bad because it can get you sick! 2. Try this question: How does mushrooms reproduce? JS: They reproduce with spores that will develop into a new mushroom! Mrs. M: Great answer!

3. Here is one to think about: At what temperature will an ice cube float? JN: An ice cube floats at 32 degrees Fahrenheit. When it gets to that point it has a density of 0.9167 g/cm3 at 32 degrees Fahrenheit.

4. I think that a sponge is both male and female. What other invertebrates are both male and female at the same time? Check it out and if you find a answer or have a question add it here! KF- I was reading in a science packet and found out so are worms! RF-Try this mix borax and glue together and keep mixing until it forms It will look so cool.P.S mix in paint the color you want.

5. A sea anemone can't move quickly. So how do you think it protects itself from predators? KF- Well it has to be someway? Well since its tentacles have barbs with poison on it wouldn't that be a way to prtect itself! I did not look this up I hope I am right! CM- They use stingers on top of them to paralyze enemies 6. Do you think there are different types of bacteria in space? CB: Maybe but, how could it get there??? Mrs. M: good question CB! LC: Maybe it's just there! Well, maybe the bacteria can't survive without oxygen? Mrs. M: You are thinking. Do you think bacteria can or can't survive with oxygen? And what would be a good place in space for bacteria to be and survive?

7. With all the news about the flu on the news, how should people protect themselves? KF- They should wash thier hands after they use the bathroom. If you sneeze in your hands wash them. You should also try to stay away from sick people. 9 .SG- What percentage of animals are invertebrates? EA: I think 97% CB: Me too. To EA from Mrs. M- very good. Which animals that are invertebrates are interesting to you?

10. LK- which kingdom has the most complicated cells? From Mrs. M: Terrific question LK? anyone have any ideas? I think the animals or the plants do. Either one of those I am sure!-KF CM- I think plants because they have a cell wall which puts them ahead 11. KG- Why do worms appear in your driveway on rainy days??? CB: because worms like shady wet places.

12. SG- What city is 2 ninth alligator, 1 half buzz, 3 eigths queen bee, 1 third red, 2 eigths question, and 1 fifth extra? It is easy if you get the concept.

13. AM- thats a cute turtle! Do turtles have backbones? JN: Turtles do not have backbones. They have a protective shell that they can hide from other animals. The shell has cool patterns. Next time you see a turtle go and look to see what kind of patterns the turtle has.Rf-They do have back bones but their attached to their shell. 14. What is the difference between a cocoon and a chyrsalis? From Mrs. M- This is a great question-Anyone out there thinking about this one? KF- The difference is that a cocoon is for moths and a chyrsalis is for butterflies! 15. CB: What is that band around an earthworm? LW: It's the fat of the worm. 16. JT: Why are a Zebra's black and white stripes helpful while running away from a predator?? To JT from Mrs. M: Another terrific question. What do you all think the answer might be? KF- They blend in with the other zebra's stripes! JT: Close. When zebras are running away from a predator, the stripes make it look like two animals. The predator gets really confused. That's why.

17. SF: Which came first the greek god Madusa or the jellyfish's madusas? KF- That is a great question! I am going to say the jellyfishe's madusa's!

18. LW: What is the slowest thing on Earth? CT- A sand dolllar, sloth, or a pink flamingo

CT- What is the fastest moving animal on earth? CM- A cheetah can go up to 60 mph

20. CM- Can a fish live in space if you bring water with you to put it in? JN- No, it would suffacate without a clean supply of water. **__Try It!__** 1. When planning skyscrappers, designers consider how people and objects can safely be transported from top to bottom during an emergency. Can you construct a system that can safely lower a coin from the top of the table to the floor?

2. Construct a bridge between 2 tables that will span at least 16 inches and also support at least one book. Use only the following materials: straws, tape, straight pins, a book and the 2 tables. What did you find out?

3. Materials: glass of water and 10-12 raisins Procedure: place the raisins in the glass of water, allow them to stand over night Result: see what happens to the raisins Did they swell up and get big? Why? Answer: OSMOSIS find out what this great science word means and why the raisins swelled up. Try it! MR-im am tring the raisin experiment and i will tell you the results in the morning before school. MR-Wow. im am really inprested. They really got big and swelled up.i compared a rasin to the water raisin and the raisin in the water, the color changed to a light brown. From Mrs. M- Glad you liked this one. Here is something to try. Take a large bowl and fill it with water. Ask your parents first but try to see which fruits float and which one sink. Let us know what your results are. Do you know why? 4. ZF - I was in the pool one day and a put my hands together and the waves crashed and formed like a whirlpool. I thaught it was my imagination so ? I tried it again a few times and it worked.

5.

SG- Take a tissue and four rubber bands and any other material to save an egg from cracking from a high drop. Mrs. M- This sounds like fun but just be sure you ask your parents first. Let me know the results! Sg- i tryed this awhile ago and it worked. I even got a few drops without it breaking. Mrs. M.-Wow, that is great. I wonder if you put an egg in a box that has wells and push the mini-car down a ramp, if the egg would break when the car (box with wheels) finally stopped. Can you think of a way to design an experiment with a box, 2 axles, 4 wheels, 1 egg, and a ramp? Let me know if anyone tries it.

From Mrs. M to whomever did the black hole...This is very creative-please see me to show me how you imported it to the page. It is awesome! From Mrs. M. - Thanks for sharing with me how you put in the black hole and where you are finding some great jokes. I won't share the place you found them. You may share the site with your classmates, well, if you want to. KG- How did you put the black hole in?? Yes, it is pretty neat. Is it like going onto another web and pasting the pic? KH says hello to all.


 * 14.Talear-DANGER!!! BLACK HOLE LOCATED BELOW: TRY CLICKING IN THE CENTER. **[[image:http://www.jupiterscientific.org/sciinfo/jokes/blackholesuck.gif width="231" height="170" align="middle" caption="black hole sucking" link="http://www.jupiterscientific.org/sciinfo/jokes/blackholedeath.html"]]

AM- I found something really interesting about frogs. In the winter they hibernate, and when they do that they kind of die. they dig down deep in the dirt to get warm, because tiny ice crystals can form in their body, frostbite, and actully kill them if it gets to their heart. Then when spring comes they will wak up and become alive again. Fabulous picture-I love it.

AM- Do you know what this is, Mrs.M? Is it a mammal or a reptile? UMMMM, I am not sure, guess I will have to do some research! from Mrs. M. AM- The name starts with a P. AM- did you notice the whiskers? MP - Thinks it is a reptile. Mrs. Mc. is not sure yet? with whisker it could be a mammal because a mammal has hair. Can a reptile have hair? AM- I found out about it in my biome book. This animal lives in the rainforest. AM- The next letter in the name is an A. Mrs. M-I think I know what it is-A Pangolin. Let me know if I am right. AM- Yes! Your right! I hope that MP didn't tell you.

WARNING - WARNING- WARNING THIS IS WHAT POISON IVY LOOKS LIKE-THIS SUMMER DO NOT GO NEAR IT OR TOUCH IT!
