Pictures of what we are doing!

Look at Sara's blog which is on her Facebook!  It is under her notes!

Container into Space

We have been working on our container.  What we have decided to put a stuff dog inside a clear container because the dog will help conserve the heat for the camera because the camera will be inside of the dog with a hole in it.  Today we will try to get the finishing touches with the camera and the dog. We hope to try out the container at least today if not tomorrow.  We will also have other soft things inside of the clear thing that holds Fluffy (the stuffed animal) and it will help protect the camera and other things inside of it.  Then there will be things on the outside of the clear container but we haven't decided on that.  Maybe we will use popped bubble wrap.

Objective 6:

1.  Acid-a compound with a taste that is sour, makes blue litmus paper red, and is a H+ ion.
2.  Neutralization-a reaction that happens between a base and an acid that yields a salt and water
3.  Indicator-a thing, like litmus, that tells the presence of a certain constituent like an acid or a base.
4.  Corrosive-eating away at something (acids are this)
5.  Hydroxide ion-an anion OH that has one oxegen and one hydrogen atom

Objective 5:

1.  They are mechanical and chemical.

2.  Mechanical digestion is when you hve to do something to digest your food for yourself like chewing but chemical digestion is when a chemical called hydrochloric acid breaks down your food. http://wiki.answers.com/Q/What_is_the_difference_between_mechanical_digestion_and_chemical_digestion#ixzz16btmgJUm
3.  This means they can't do mechanical digestions so the chemical digestion has to work harder.
4.  mounth=7pH, stomach acid=1.5pH, small intestine=7

5.  The different enzymes work better at different pHs.

Objective 4:

1.  H+
http://wiki.answers.com/Q/What_ion_is_present_in_all_acidic_solutions
2.  The acids make hydrogen ions and the bases make hydroxide ions.

3.  It ends up breaking down into H+ NO3 which is an acid.

4.  The pH tells you how much H+ ions that are inside of a certain acid or base.  If the pH is lower than 7 it is an acid and if it is higher it is a base.
(remembered this from the question on objective 3)
5.  The concentration of hydrogen is pretty high when the pH is low which means the pH of 3 has more hydrogen ions than the pH of 7.

Objective 3:

1.  They are if something tastes sour, if it reacts to metals or carbonates, if it turns blue litmus paper red, a pH lower than 7, and lastly if in a solution it produces hydrogen ions.
http://wiki.answers.com/Q/What_properties_distinguish_acids&alreadyAsked=1&rtitle=What_are_four_properties_of_acids&isLookUp=1
2.  They taste bitter, feel slippery, can be caustic, and turn red litmus paper blue.
http://wiki.answers.com/Q/What_are_the_properties_of_bases#ixzz16botVnjO
3.  If the paper turns red it must be an acid and if it turns it blue it must be a base.
4.  You can tell because if the food is sour it is a acid and if it is bitter it is a base.
5.  You need to wear gloves because the fertilizer will hurt your hands.  Also allows you not to wash your hans so often while doing gardening.
