==Students are briefly shown how you can test each of the three senses (sight, sound, touch) reaction time through dropping and catching a ruler. Each group must then set up a full prove experiment (controlling all variables except reaction time of sense) before they can test which sense is the fastest. Once their plan is approved by the teacher they are then given the materials to test this experiment. Students will go through all the steps of the sci-method from making hypothesis and conclusion to creating own data tables and graphs.==
 * Lesson Topic and Description:**

**__Focus on Concepts__**
1. Seven steps of the scientific method 2. Controlling variables, devising experiment to see which reaction (sight, sound, touch) will have fastest reaction time 3. Creating a graph 4. Creating a data table You could even have them create this in excel because that can be a worthwhile skill! Create everything on paper and then have them transfer it to excel and create a graph there, as well.

**__Provision for Acceleration and Compression of Content__**
The time of the lab will depend on how fast each group comes up with a suffiencent way to test this experiment. Once checked by the teacher (all variables are controlled except speed of senses) the teacher will give the group materials so they can conduct their experiment.

**__Enrichment__**
Once the experiment is finished, each group can brainstorm any ‍‍errors ‍‍that could affected their data. They could also brainstorm the biological reasons why one sense my provide a faster reaction than another sense.

You could have them repeat the experiment then reducing the possible errors that affected their data, OR you could have them set up another experiment that would help verify their results in another way.

**__More Advanced Reading and Vocabulary__**
Give HA groups less hints on how to solve the problem. Make each group accountable for controlling all variables on their own. Just give each group a blank sheet of graph paper and have them set up entire graph on their own. Students will also create their own data table on a blank sheet of paper.

**__Use of Primary Sources, Artifacts, and Real World Objects__**
Students can brainstorm real life observations on which of their senses would have the quickest reaction time. (person braking at a red light versus pulling hand back when touching a hot stove)

**__Interdisciplinary Connections__**
Students will need to be able to work well with others and agree on a common appropriate way to test question given. Students will need to be able to organize their data through an appropriate data table. Students will need to be able to display their results through an appropriate graph. Could have them research famous people who didn't have one of those senses and describe the challenges involved in maintaining a high functioning life.

**__Includes In-Depth and Critical Analysis__**
Students cannot test their experiment until it is checked by teacher that all variables are controlled except for reaction time of senses.

**__Fosters Creative Expression__**
Students can brainstorm on their own which factors must be controlled to come up with an answer for the problem.
