This bundle is a fabulous lab-with-supports for middle school science. Experimental design, data collection, graphing, predicting - it's all here! Use this fun and engaging lab to get your student's brains thinking like a scientist. :) The lab activity uses your student’s reaction time to practice data collection, inquiry, and using the scientific method. The powerpoint included encourages academic discourse, collaboration, predictions, and justification of answers. Get your science discussions started by talking about what kind of data to collect, how to collect it, and how to use the data and graph to develop a conclusion! Math skills play a part in this lab too - averaging, and using a distance-time graph to find reaction time.
One thing all time-strapped science teachers can appreciate - very few materials are needed! Just meter sticks and timing devices - I have my students use the ubiquitous mobile phone :)
The effect of gravity on freefall objects and distance versus time graphing are explored in several mini-investigations: reaction time with stopwatches or timers, reaction time catching a falling meter stick, and reaction time when having to make a decision.
The labs are highly engaging - students love to compete to improve their own reaction time. The concept of the lab activity is so simple that students can easily concentrate on the experimental design and data collection/interpretation without getting bogged down by not quite understanding what it is they are doing.
Basic physics - the acceleration of objects due to gravity is touched on and there are opportunities to use the distance formula - if your students are ready - or keep the discussion more conceptual. Either way, your students will get great practice in gathering data and drawing conclusions with this set of activities.
It includes a distance-time graph of an object in free-fall, so students can use the data in their lab to calculate time without using the distance formula. If your students are ready for the math of the distance formula, you can edit the powerpoint and have them calculate their reaction time.
Also included is a post-lab quiz, a homework assignment where students design their own reaction time lab, and an activity that challenges students to catch a dollar bill in mid-air and then explain - using data from their lab and what they understand about physics -why catching the dollar bill is nearly impossible.
In all you get:
one 26 page powerpoint investigation
a quiz that relates directly to the skills and understandings acquired in the investigation
a homework assignment that encourages students to design their own investigation
a “dollar bill challenge” mini lab that includes a writing prompt
The powerpoint, quiz, and homework assignment are editable so that you can differentiate for your students’ needs.
The preview file is a pdf of the entire packet so that you can determine the suitability for your needs.
For a limited time, this product is bundled with my popular scientific method bundle, metric system unit, task cards, jeopardy games, and other inquiry-style labs in my Mega Bundle. It's everything a Secondary (gr 6 - 9) Science teacher needs throughout the year. You can find it here: Middle School Science Mega Bundle - Limited Time Offer
