Lesson+Three-+Experiment

This day the students worked on their experiments.

** Lesson Plan 3: Step 2 – Experiment  ** April 20th, May 4th, and 11th, 2011 ** Purpose: ** Students will write out the procedure for their experiment and then complete the actually experiment in one to two hours. ** KUSD Standard: ** B-2: nature of scientific process and knowledge Standard C: science inquiry—students will investigate questions using scientific methods and tools, revise their personal understanding to accommodate knowledge, and communicate those understandings to others. C-2: Make connections to prior knowledge. C-3: Gather background knowledge related to the questions being investigated. C-5: Safely use appropriate senses, equipment and tools to make observations and gather data. C-7: Summarizing, synthesizing, inferring, and building explanations ** Context: ** Students will be applying the scientific method as they write up their procedure and complete an experiment. This lesson focuses on step two of our process have completed an experiment with little to no assistance. ** Planning Ahead:   ** ** Materials: ** Group1 1) Can you sink an orange?   -oranges, 2 bowls, tape, toothpicks, napkins    2) Exploding Bottles -2 buckets, water bottles, tongs 3) Tug of War   -rope, gloves, scissors, directions for different types of knots    4) Notes a teacher can’t see -q-tips, paper, juices Group 2 1) Salty Eggs   -2 cups, salt, eggs    2) Floating Play Dough -play dough, bucket, bubble wrap, toothpicks 3) Lava Lamp Creation   -Water bottle, food coloring, vegetable oil, water, cups    4) Balloon Rockets -different size balloons, tape measure, tape, straws, string, chairs 5) Growing Crystals   -pencil, string, weights (nuts), small container, salt    Group 3    1) Spinning Eggs -raw eggs, hard boiled eggs 2) Rock and Sound   -rock, paper towel tube, tuning fork, bucket, ziplock bag, clock    3) Ice Pen -pens, tongs, 2 buckets, play dough 4) Go Boat Go   -tin foil, wave table    ** Motivation: ** Students will get back into their groups and write up the procedure for their experiment. Once their procedure has been approved by one of us, the students may begin working on their experiment.    ** Development: ** Students will begin the lesson by reviewing the steps of the scientific method. After a short review, the students will move into their groups and start writing out their procedure. Then when the procedure has been approved they can move into their experiment at their own pace. All of the supplies that they asked for and that we believe they will need will be placed in front of them on the table. Once they finish their experiments, they will clean up their area and return upstairs.    ** Expectations: ** Students will be expected to write out a procedure that can be replicated by another student in their lab notebooks. Both students must have the procedure written down and it must be approved before they move on to the experiment. ** Assessment: ** Students will not receive a grade for this lesson. We will be looking at the completion of their procedure and their experiment. ** Adaptations: ** Each group will have a different experiment so the support will be based on what experiment they have chosen. Students in grades 4th and 5th will also receive more attention than the groups in 6th grade since this is the first time they are seeing the scientific method.
