Earthquake tower challenge

 Earthquake tower challenge 

we had to design and construct a two-story building using the

following materials!

-1 cardboard base (approximately 25 cm by 25 cm)

-30 straws

-100 paper clips (one box)

-20 pins

-2 meters of string

We (as a group) had question’s that we had to answer!

Our first question was.

what are the strongest parts of my building. was the walls because it keep the hole building up

what are the weakest prats of the building was the bottom of it because the bottom keep on coming apart so we tied the string up around the paper clips and pins.

where did you use your string in your structure. we put the string on the outside of the structure and we put it at the bottom so it can hold it up

Then we put the sand in the middle of the tower then we counted how many second that the structure can hold the sand it holed it for 2 second and then it was morning tea. Ather morning we keep on building structure then we put the sand in the middle again and holed it for 43 second

the end

whats is matter

Today we have been learning about the three states of matter (solid, liquid and gas) and the changes of matter. In this experiment we first we put chocolate chips in the microwave.

This meant that the chocolate changed from a solid to a liquid. Then we pour the chocolate to make shape This meant that the chocolate changed from a liquid to a solid when it cool down.

Density

Density

We did an experiment on Density.

Question

What happens when you drop an egg into ordinary drinking water and an egg into salt water?

Observation

The egg in the glass of ordinary water sink to the bottom

The egg in the salt water floated to the top.

Conclusion

This happens because salt water is denser or heavier than ordinary water. It was easier for the egg to float.
