Lessn Plan Reach: Ask the students if they ever ppped a bag f micrwave ppcrn and nticed hw many kernels were unppped at the bttm f the bag which made yu wnder if ther brands pp better than the ne yu are eating. In just that shrt time yu have dne tw steps f the scientific methd. Tday yu are ging t learn hw yu culd slve yur prblem using the ther steps f the scientific methd. Lessn: We will take guided ntes abut the steps f the scientific methd. I use pwerpint pictures t g alng with the ntes and as we g thrugh the ntes I will relate the steps and terms t ur ppcrn prblem. Reflect: At the end f the lessn, they will write in the jurnal sectin f the ntebk. They will reflect n the fllwing questins: What did I already knw? What did I learn? What d I nt understand? After, they fill in their jurnals, then they will share with their lab grups. Hpefully during that time, they might be able t explain t each ther the things that they might nt have understd. During that time, I will be walking arund the rm listening and prviding reinfrcement and sme further explanatin if needed. Recde: They will d a graphic rganizer t sequence the steps f scientific methd. Rehearse: We will perfrm a lab t rehearse the steps f the scientific methd. During the lab they students will need t identify which step f the scientific methd they are perfrming. They will als practice analyzing their data and frming a cnclusin that they will cmmunicate with the class. Anther way we will rehearse, is they will have a hmewrk assignment where they will be reading an example experiment. They will identify the steps f the scientific methd in the example and they will als identify the parts f the experiment. Review: The lab grups will cnstruct a mind map pster f the steps f the scientific methd and share their psters with the class. Retrieve: The students will have a written assessment n the scientific methd.

Bilgy Independent and Dependent Variable Practice 1 Name and # Date Directins: Please identify the independent and dependent variables in the fllwing descriptins f experiments: 1. Students watched a cartn either alne r with thers and then rated hw funny they fund the cartn t be. 2. A cmprehensin test was given t students after they had studied textbk material either in silence r with the televisin turned n. 3. Sme elementary schl teachers were tld that a child s parents were cllege graduates, and ther teachers were tld that the child s parents had nt finished high schl; they then rated the child s academic ptential. 4. Wrkers at a cmpany were assigned t ne f tw cnditins: One grup cmpleted a stress management training prgram; anther grup f wrkers did nt participate in the training. The number f sick days taken by these wrkers was examined fr the tw subsequent mnths. 5. Students at a University were split int tw grups and each received a different text fr a philsphy curse. Once grup received a traditinal text bk, while the ther received an interactive textbk n a tablet cmputer. After the curse, the final exam marks between the tw grups f students was cmpared. 1 https://www.amal.k12.nf.ca/amal/pluginfile.php?file=/14847/.../variable+wrksheet..
Bilgy Thinking Critically Name and # Date Directins read the fllwing infrmatin abut a student s experiment and then answer the questins that fllw in cmplete sentences. A student nticed that when a dg is cut, the dg peridically licks its wunds. Usually after a few days, the wund begins t heal withut ever shwing signs f infectin. The fllwing steps utline the student s line f reasning: A. I wnder why the dg s wund desn t becme infected. B. The dg s saliva must prevent the grwth f infected-causing bacteria. C. I ll btain a bacterial culture and grw the same kind f bacteria in tw identical culture dishes. Once the bacteria start grwing, I ll add dg saliva t nly ne f the dishes and leave the ther alne. I ll cver bth dishes. Then I ll bserve what happens each day fr a week. D. Even after adding the dg saliva t ne f the dishes, the bacteria cntinued t grw in bth dishes ver the curse f the week. Hwever, the bacteria in the treated dish grew mre slwly than the bacteria in the untreated dish. E. I think I ll try smething else. I ll start with tw identical culture dishes, as befre, and use the same kind f bacteria in each dish, but this time I ll treat ne dish with dg saliva befre I add the bacteria. I ll bserve what happens each day fr a week. 1. What part f the scientific methd is illustrated in step A? 2. What part f the scientific methd is illustrated in step B? 3.
