Middle School STEM Science Lab/Activity Planner Name of Lab/Activity: Grade:7 Eggcell California Science Standard(s): (please copy and paste standards taught during this lesson) Students know the characteristics that distinguish plant cells from animal cells, including chloroplasts and cell walls Common Core Science Reading and/or Writing Standard(s): (please copy and paste standards taught during this lesson) conduct short research projects to answer a question, drawing on several sources and generating additional related, focused questions for further research and investigation Learning Objective/Goal: Discover how a semi-permeable membrane works Language Objective/Goal: (based on California Common Core Standards) Support claims with logical reasoning and relevant evidence, using accurate, credible sources and demonstrating and understanding of the topic. Next Generation Science Standards ): – (please copy and paste any of the 8 Science and Engineering standards taught during this lesson, as well as any Cross Cutting Concepts that apply) Materials & Resources: Eggs, traditional vinegar, food coloring, salt water, corn syrup, kiwi, tomato, shampoo Procedure: Place egg in traditional vinegar to decalcify. Teaching Notes: (include timing) Students hypothesize what will happen when they place Same experiment can be done the egg in the different liquids. Then place softened egg in with eggs not soaked, soaked in salt water, shampoo and corn syrup that have been standard vinegar and eggs soaked colored different shades with the food coloring to in concentrated vinegar differentiate. Liquids remain un-labeled so students can observe without knowing what the liquid is. Weigh daily for several days and record results on data table. Use data table to create graph on excel or word. Record in science journal daily observations including text with complete paragraphs, diagrams and labels. At end of the week students conclude their observations using the academic language discussed during the week. They are then given a list of fluids (including those used) with similar viscosities and try to identify which liquid were used and why. Wrap up discussion by identifying actual liquids and why each liquid had the results it did. Repeat all steps( except soaking in vinegar) with kiwi and tomato simultaneously with the egg.
