Ballon experiment.





I think that 15 will be the largest.

The correct result was that 10 was the largest.

One variable  would be  the beaker

                                                             Atoms/Molecules

     Atoms make up matter, which makes up everything. The properties of matter are solid, liquid, and gas. If you polish a piece of metal it has luster. A water is made up of two hydrogen atoms and one oxygen atom.

Ants in Space.

     We studied ants in space. But, instead of doing the investigation on the ISS we did it here on Earth.   I was in charge of taking pictures and what is the ratio between the amount of time moving and the amount of time at rest. I collected data the entire investigation. The ratio is 5-18. I would like to do this investigation again, but with a different kind of ant.

Solar Oven Investigation

We have been testing solar ovens in science. These are my observations. The question is what oven heats up the fastest. The first oven started at 23.1°c after 3 minutes the temperature was 29.3°c and after 3 minutes of cooling the temperature was 26.0°c. I think it heats up because of the black paper at the bottom of the box. It cooled down because the black paper absorber the heat. The second oven started at 23.6°c after 3 min the temperature was 25.2°c and after 3min of cooling the temperature was 21.5°c. I think that the second oven heated up slower because there was plastic instead of black paper. The way solar ovens are built effect the results.

Test tube

     What I liked about the cartoons is that they were funny and educational. There was one cartoon where they talked about desert ecosystems and another one that talked about a river ecosystem. I really liked their cartoons.
