8 Essential Science Practices
SP 1 – representations & Models
Use representations or models to represent scientific phenomena or solve problems.
SP 2 - Calculations
Use Mathematics and Calculations appropriately.
SP 3 - Questioning
Engage in scientific questioning to guide inquiry based investigations.
SP 4 – Collect Data
Plan and implement data collection strategies in relation to specific scientific questions.
SP 5 – Analyze
Analyze and interpret evidence gathered from an investigation
SP 6 - Justify
Justify and explain data results and analysis through debate and argumentation
SP 7 – Identify errors
Be able to identify and construct explanations of data collected and identify errors made & possible improvements in investigations.
SP 8 - Connect
Connect concepts learned and discussed in class to society, technology and the environment.

The using and Incorporation of the 8 SP
During the first unit, we learned many things using the 8 SP. We learned how to use the charts in the Excel to make a clear Scatter graph with x and y lines, which is the first step, representation and models. Then we learned how to calculate the circumference of the earth and also the formula of Newton's Law Of Cooling/Heatin, which is the second step, calculation. Then we engaged questions that were "would adding milk to the coffee affect the speed of temperature going down" and "is the earth a perfect sphere", and this was the third step, questioning. After having the questions, we had the 4th step, we collected many data during the experiments and investigation. Then, we compared the data we collected and found out that adding milk does affect the speed of temperature going down and also earth is not a perfect sphere, which is the fifth step, analyze. The next step is justify, so we talked to others and to see if we get the same ideas, if our results are all the same, then we are fine, if they are not the same, we have to find out who did it wrong and where went wrong. Then we tried to find out any errors in my experiment, for instance, the thermometers sometimes would accidently touched the bottom of the beakers, so we tried to solve it by not touching the bottom, and this is the step 7, identify error.Then step 8 is connect, we connected the formula and concept we learned and thought about some other experiments that were related to this experiment that we could do.
Refection of Unit 1
I used to think that the reason why the speed of temperature going down is slower after adding milk was because the fat in the milk, now I know it is because the cooler stuff's temperature will goes down slower.
I used to think the earth is a perfect sphere, now I know it is not.
I used to think that it is almost a miracle to calculate the time of death, now I know there's a formula of cooling and heating that we could base on.
I used to think that everything cools down for no reason, it is just a process of losing heat, and will keep losing heat, but now I know it goes down to the surrounding temperature.
I used to think that when we were doing the coffee project, we should use the same amount of coffee (after adding milk), no I know we need to use the same amount of mild before adding the milk.
