STARTER 8/15-16 1. In Science Journal in Starter: 2. Differentiate between the independent, dependent and control variable. How can you know the difference? 3. Please take a worksheet from the front stool. Review the scientific method and variables by completing the 1st page. SPI 0807.Inq.1 Design a simple experimental procedure with an identified control and appropriate variables. SPI 0807.Inq.2 Select tools and procedures needed to conduct a moderately complex experiment. SPI 0807.Inq.3 Interpret and translate data into a table, graph, or diagram. SPI 0707.Inq.4 Draw a conclusion that establishes a cause and effect relationship supported by evidence. SPI 0807.Inq.5 Identify a faulty interpretation of data that is due to bias or experimental error.

Slime Lab Partner up . 1 & 2, 3 & 4, 5 & 6, 7 & 8, 9 &10 etc. Assign jobs. Mixing and gathering supplies. . Procedure: Fill beaker with 50 mL of water. Put in 1/4 - 1 tsp. Of borax into beaker and stir until it is fully dissolved into the water. Fill the ziploc bag with 4 oz. White glue Pour 1.5 tsp of the borax/water solution into the ziploc bag at a time. Squish it around for 2-3 minutes and see what happens.

Error analysis: In the embedded Inquiry, SM of your One Note notebook list and explain three possible sources of error in the slime lab. Then suggest a method for reducing those specific examples of error in this activity.

SUMMARY S (statement)- Bias and error cannot be completely eliminated from experiments. O (opinion)- S (supporting evidence)-
