TWIS #13

If we sealed the tank and removed all the plants,then the spider would die because there are no plants to make oxygen for the spiders.There would only be carbon dioxide which spiders can't breath in.Photosynthesis would make glucose for the plant by using water,air,and sun energy.

TWIS #12

What i Did

We got our spiders that are daddy log legs (cellar spiders).But this week we fed our spiders and we got to watch and observed them while they eat.We also learned about symbiotic relationships.We made Spider Observation Logs and decorated them.And the last thing we did was we went over regions questions.

What i Learned

We fed our spiders flightless fruit flys and while our spider was eating them i realize that it spins a web first with its back legs and then sinks its fangs into the insect all over the insects body.The next thing we learned was about symbiotic relationships.There are 3 different types: parasitism, mutualism, and commensalism. Parasitism is when an animal will benefit from another animal but the other animal will actually be getting hurt(+,-).Mutualism is when both animals will benefit from each other(+,+).And last Commensalism is when one animal benefits from another animal but the other animal will not get anything, having no effect(+,0).In our Spider Observation Logs we did background research on daddy log legs (cellar spiders).And we also learned about how to answer regions questions.We learned that they word the questions in complicated ways to try to confuse you.Thats why you have to read them carefully and try to find out what they are asking you.
