General Science Class And Grade 9

4. Predict: What do you think is the density of the whole block of Styrofoam? 0.2 g/cm3

E. What would happen if you dropped the object into the beaker while using the Archimedes’ Principle method instead of submerging the object?

11) The gas accumulation in the balloon was measured and recorded at one minute intervals for a total of 10 minutes (qualitative observations were included)

Mrs. Collins addressed the 6th grade Science class with the most uplifting positive attitude that anyone could have. Every day she came to class she always had candy and snacks sitting on her desk for students to enjoy when they were on their best behavior or if students participated. Everyone insisted on behaving and participating just so they could get a treat. One day Mrs. Collins called on a young boy whose name is Mark, but everyone else addressed him by meanie mark. Mrs. Collins asked Mark if he would like to come to the front of the class and demonstrate the Mentos and coca cola project. Mark did not say anything the first time. The second time she asked he murmured something, no one could not hear what he said. He set in the far back left corner of the classroom by himself. No one wanted to sit next to Mark for he intimidated everyone that he came across. He always wore black and he never spoke to anyone no matter how nice they were and he always had his head down. Mark was a loner. Furthermore

that ask three to five questions about the materials required for the day’s class preparations –

2. Read and record the temperature of the gas using the thermometer attached to the container.

Assessment: I will observe student behavior during their discussion and during the creation of their self-portrait. Also, I will assess students’ ability to come up with 10 positive

What evidence will you gather at the beginning of the lesson, during the lesson, and/or at the end of the lesson that will show the extent to which the students have made progress toward the academic learning objective(s)? Attach rubric or scoring guide as appropriate.

Describe the pre-assessment(s) used to establish all students’ baseline knowledge and skills for this lesson.

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

After we had the balloons with filled with 10mL of vinegar each, we attached them to the baking soda test tubes. After all the components had been situated, we carefully lifted each balloon to pour the vinegar in. We made sure to closely compare which balloons had inflated more than others, and to see if any baking soda was left behind. A good technique to utilize would be to take pictures of the results; a technique that my group could have benefited from should we have used

b. Place crushed ice in the beaker so the water level is just below the top of the

In order to perform this lab, the students will require a measuring tape and calculator.

They are given several minutes to explore. Students must find a desirable question to research and conduct the experiment based on their observations.
