Good afternoon Hornets!
This was a fun filled week of interactive lab investigations as well as the Jim Jones Basketball assembly.
We started off the week on Monday spending the day checking our homework of page 14a and 14b of our interactive science notebooks. Students had to classify a list of examples as physical or chemical changes. Students also had to develop a reason why the example was a physical or chemical change. After we classified matter as either change, we developed a T-chart of evidences to look for in the lab when we are observing either change.
Tuesday-Wednesday we conducted an experiment of 6 different activities. Each activity students had to read a list of 2-3 short directions of what to do. Then students would observe the matter change and classify it as either physical or chemical change. Some of the activities included observing what happens to a candle wick when we burn the candle, or observe what happens to the wax (physical or chemical change). Another activity included crushing a sugar cube and deciding what type of change it was, burning sugar in a test tube and observing the color and smell change.
Thursday we had the Jim Jones assembly during 2nd and 3rd hour. Other hours watched a Bill Nye the Science Guy video on Chemical Reactions and had a video worksheet to go with it consisting of 15 questions.
Friday- I conducted two demonstrations as part 2 of the lab we did earlier this week on Tuesday-Wednesday. First demonstration was making iodine clock. Students observed me mix different types of chemicals in a beaker and watch the dramatic and unexpected color change. Students were able to tell that it was a chemical change because there was an unexpected color change within the substance. The second demonstration was making elephant toothpaste. Students observed hydrogen peroxide, water, yeast, dish soap, and food coloring mix in a beaker. The chemicals mixing caused gas bubbles to be released and the substance poured out of the beaker kind of like a volcano. Students were able to classify the substance as a chemical change and give reasoning based on the evidence we charted out on Monday.
Things to consider:
Next week we have the 7th grade field trip on Tuesday. Make sure all permission slips/money are turned in. Also please make sure to remind your child that we are proud hornets. We represent Woodworth Middle School everywhere we go. It is important that we are respectful to places that welcome us, staff members, and any volunteers. It is important that students follow directions so we can have more reward opportunities in the future and everyone is safe.
This upcoming Wednesday is late start day. Students start at 9am instead of 8am!
Friday will be the first bellwork quiz for this second part of the unit Matter and Its Interactions. Make sure students are doing their daily bellwork, checking their answers, and studying at home as well to prepare for the quiz.
