SCI 100 Module Four Activity Template (2)

What materials will the teacher and the students need to complete a lesson on mixing substances in a 5th grade classroom based on the below standard and learning objective? Standard Conduct an investigation to determine whether the mixing of two or more  substances results in new substances.  Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.

You collect a sample of seawater containing salt. The original sample weighs 15.67 g. You dry the sample until there is no remaining water. You weigh it again. 0.78 g of salt remains. What was the percent of salt in the sample? Round to the nearest percent.

Need all three plz

Supply the missing information in the table. (Given in Blue). Answers in scientific notation should be in this sample format >>> 1.0 x 10-14

Try Again Your answer is incorrect. Classify the substance shown in the sketch below. You can click the other tabs in the sketch to get a magnified view. Be sure you check all the boxes on the right-hand side that are correct for this substance. Note for advanced students: in some sketches the distance between particles has been exaggerated to make it easier to see each individual particle. normal substance 1000X 10,000,000X classification (check all that apply) gas liquid solid element compound mixture solution pure substance homogeneous mixture Oheterogeneous mixture X Ś
