What did we Learn from the egg drop experiment? Mrs. Thiry’s 4th and 5th grade classes
We were given a problem”How do we get an egg to not break when dropped from a distance?
We made a hypothesis:what could we fill our container with that would prevent the egg from breaking?
What were the control variables? • We dropped it from the same height. • We dropped it the same way. • We used the same icing containers • We dropped it onto the same surface.
If the control variables weren’t the same would the comparisons between the containers be fair?
If you were successful, your results won’t be accepted until:Your experiment is…1. repeated by different people.2. Repeated in different places3. Repeated at different times
Were there any potential hazards or precautions involved in this experiment?
If your conclusion didn’t match your hypothesis (your egg broke)what should you do?
Quiz 5th grade • Name 2 control variables. • We used the scientific method. What is the acronym we memorized and used? • In order for your results to be accepted, they have to be repeated by different _________ in different _________ and at different ________. • What were the independent variables from the 4th grade experiment (or the girl in the playhouse experiment we watched)?
Quiz 4th grade • Name 2 control variables. • We used the scientific method during our experiment. What is the acronym we memorized? • Why is important to keep some things the same in our experiment? • When one group dropped onto a softer surface, was this a fair experiment?
