Cricket Investigation

Question: Do crickets prefer wet or dry environments?
Hypothesis: If i have one side of the tank dry and the other side wet then i think the cricket would stay on the wet side because it would be more comfortable.
Background Research: To survive crickets need a place to stay such as under a rock and in a log in meadows. Crickets need food, they're omnivores so the eat plants and animals. They also need warmth and a good environment to live in.

In our investigation we have a cricket and see which side it likes better wet or dry. We was keeping track of it by using method 2 which is putting dots down everywhere the cricket stopped. We cut a paper towel in half and put one on each side. Then we wet one paper towel on one side and left the other one dry. We then got the cricket put it in the tank and recored data using method 2.
Our cricket did not want to stay one place it was on the wet and dry side so we don't know which side it liked better. The cricket was just going around and around from the dry and wet side. This was a good method because we saw everywhere the cricket stopped and how fast it moved.

TWIS #6

This week in science we did a experiment with crickets & observed them. Each group got 2 tanks with 2 crickets in them and we had to see what the crickets like better, dry or wet surfaces better. We had 4 different methods to keep track of which side the cricket like better. We also had a mission challenge with jelly beans. What we did was separate the different kinds of jelly beans to what each of them had in common. 

What i learned in science was what a dichotomous key was. We used a dichotomous key to do a mission challenge with Jelly beans. We . What i also learned was crickets like the wet surfaces better. I think its cause its more damp and they could be clean. What i also learned was that there is 4 different methods to keep track of the crickets and how far they moved.

This Week in Science #4

This week in science we worked on our plant investigation. We also had a data day where we collected data from everyone in the class and graphed it. What we also did was have a investigation write up Day 1 & investigation write up Day 2. What we did those days was worked on the laptops & did our write up and each of the group members did everything they had to do for the write up.

What I learned this week was that its hard working in a group with 3 other people because some people don't understand what they have to do. Some people get mad because they don't want to do certain things so its really hard working in a group of 4 depending on what your working on.

This Week in Science #3

 This week in science we worked on our Plant investigation with our groups. We measured our plants and saw how they grew over a matter of time with 2 cups in the dark and 1 in the sunlight. This week we also got in our groups and did a mission, where you had to go around to everyone and ask them what kind of pets they got. We then gathered the information and made a bar graph, line graph and a pie chart based on the data we got from everyone.
 This week in science I learned that even if some plants don't get sunlight they could grow because they still get water so they could still grow. This week I also learned more about the independent and dependent variables for our plant investigation. Then I learned about how the hypothesis has to be (if, then, because).

This week in Science #2

This week in science we played with the poppers seeing how high they popped and was investigating them and made up questions with the dependent and independent variables about them. We also got new seats and started to look up research for the new plant Brassica Rapa. Then we got in our new groups and started our plant investigation #2 with BrassicaRapa. In our groups we then got our cups with soil and got 3 little seeds for each cup and planted then. Then we put water in them and put 1 cup in the sunlight and the other 2 in a closet with no sunlight.

During this past week in science we learned about Testable questions, independent variable and dependent variable. A testable question is a question that can be tested through observation. A independent  variable is a variable that the scientist changes on purpose. And a dependent variable is a variable that can be measured. We also learned about  BrassicaRapa which is the plant we are now growing in class.
