Welcome!
This site will be used to list what we’re studying, resources, interesting sites, practice tests, notes from class, and activities that relate to our topic. Some of those activities will be used in class while there may be some that are strictly listed for fun. Most links will be science related and should be very kid-safe. I check each site myself to ensure that there is no content that might be objectionable.Science Trivia

Learning Target – I can identify chemical and physical changes and properties and use them to identify an unknown substance.
Most classes got to test unknowns today to see if they could figure out what they were. Some did better than others. We’ll get about 10 minutes in class tomorrow for those who didn’t get their first one and for those who’d like to earn some bonus points to do a second one.
Today’s homework was a reading sheet with questions on changes and properties.
Learning Target – I can identify physical and chemical properties.
Unknowns lab again today. We’re finishing up tomorrow. We’ll come in, run flame tests, then be ready to get our sample to identify.
Because this is taking a while, we won’t have a quiz. Instead, the questions over chemical and physical changes will be added to the next test which will be after compounds, elements, mixtures and conservation of mass. Sound like fun? Just wait.
On a different note, due to the increase in students who are not turning in homework, after this 6 weeks, my “freebie” will be gone. Way too many people not turning in homework as they should.
Learning Target – I can identify physical and chemical properties.
Unknowns lab started today. Yay for us! It’s taking longer than I planned, but we’ll get there. Tomorrow, all tests will have to be completed. It looks like, for most classes, getting your unknown to identify will be on Thursday along with your Chemical and Physical Changes and Properties Quiz. Please remember, this is only a quiz.
Homework is the following extended response.
Chemical and Physical change Extended Response
You are to answer the question below using the space provided at the bottom of the page. Please use the 10 steps to remember you were given before Christmas. You must identify and define your vocabulary as well as identify parts A and B of the question and answering both.
Susan places five drops of red food coloring into a beaker containing 50 ml of clear liquid in a lab exactly as the directions tell her to do. Still following instructions, she then adds 10 ml of a blue liquid to the beaker. Upon doing this, the liquid changes back to clear. Identify each of these steps as either a chemical or physical change. Justify your decisions.
Learning Target – I can use inquiry to investigate things in my world.
We did an M & M lab today which took into account those chemical and physical changes and properties we’re working with right now. We played around with density and solubility. It was alot of fun and I hope everybody learned at least a little something!
Learning Target – I can find volume and mass of irregular and regular objects.
Lab Day! Again! Tired of them yet?
We learned how to find the volume of shapes, even if we couldn’t use a ruler to measure the sides. We practiced using our graduated cylinders and our metric measuring skills. Excellent job, guys! We’ll finish tomorrow and then find the density of the objects as well.
Homework – Everyone is writing their proposal for their research project. You have a form to use for that. If you want to type it, that will be great. Just remember you have to name your topic, tell why you chose it, what it has to do with science, what you already know, and what you plan on doing for your presentation.
1st, 2nd, and 4th period have an extra homework assignment. They are to do an extra sheet on chemical and physical changes.
Learning Target – I can identify and create chemical changes.
Lab day! We played with milk and vinegar and baking soda and more vinegar! Good job, guys! Hope you learned something about chemical changes.
Learning Target – I can identify chemical and physical changes and properties.
This was a “catching up with notes” day since we were out on Friday. We have just about completed the notes that we need for Chemical and Physical Changes and Properties. Tomorrow, all classes but one will be doing chemical changes mini labs.
We’ll have a volume and density lab on Thursday, and we have a special lab on Friday in reward for our ThinkLink score comparison across the district. Great job, guys!
Homework is a sheet on Chemical and Physical Changes and Properties. Remember not to look up definitions for the middle section.
Notes for this section will be posted soon. The test will be next week after we do our Unknowns lab which should be Monday and Tuesday, but I”ll let you know for certain tomorrow.
Learning Target – I can monitor phase changes by monitoring temperature.
We finally got to use the new burners today. Classes did a great job of being careful and using their best lab skills. Awesome job, guys.
Homework is to graph the data you gathered today while monitoring the temperature of your water as the ice melted and beyond. Remember, Time goes on the bottom and you’re counting by 1s. Do NOT skip!
Learning Target – I can understand units for measuring temperature and liquids.
Quiz was given in 1, 3, 4, 5 periods for using a thermometer. We’re ready to move ahead with our labs. 2nd will take theirs tomorrow. In classes that did not meet, we’ll also practice reading graduated cylinders again.
Homework for 1, 4, and 5 – Choose two objects and list 10 physical properties of each.
