This chapter has been fun, but not my favorite. I know a few things such as, definitions of words, the functions of what the objects do, and a few other things. The best part has been the labs and seeing how things change over time(which is why I chose my title because of the egg experiment we had). Also, the worst part has been getting ready for the test because I am not as good with this unit, but I am still pretty good. We have done some labs and they were all fun.
