This PDF includes 32 task cards that allow teachers to assess their students' knowledge of calculating work and recognizing that simple machines make work easier (please see the extensive list of content that is covered below). A student answer sheet and teacher answer key are provided. An editable task card is included so that you can add your own task card question or task. The following content/topics are included: •definition of work •recognizing that in order for work to be done, the object must move in the direction of the force applied •calculating work when given the work equation •simple machines make work easier, but they do not decrease the total amount of work •the effect of distance increasing and force decreasing •spring scale is the tool used to measure force •using data tables to determine people who are performing the same amount of work •examples of work being done •definitions for force, distance, work, Joule (or Newton-meter) •how a simple machine, such as an inclined plane (ramp on a moving truck), effects work and the amount of force needed to move a box into the truck © Science Teaching Junkie, Inc.

This product is a color-by-number activity that allows students to answer various questions relating to matter. And YES- even secondary students love to color! There are 12 different questions with 2 answer choices for students to choose from. Each answer choice corresponds to a different color. If all of the correct answer choices are chosen, then their final picture will be colored correctly to reflect complete mastery of the content. Terms/concepts students need to know in order to be successful with this product are: •(states of matter) solid, liquid, gas: speed of molecules, energy between particles, attraction, space between particles, firmness, volume, shape •boiling point •freezing point •melting point •density, volume, mass This could be used as a quick assessment, a homework assignment, additional practice, extra credit, or for early finishers. These are also great for days when you have to be out of the classroom - a sub can easily take over this lesson! © Science Teaching Junkie, Inc.

In this 2 part-lesson, students will collect data on fossil evidence and create their own landmass map with various colors to represent the locations of fossil discoveries. Then, they will cut out the landmasses and reassemble them logically to create a giant supercontinent (Pangaea). Students will share their decision and reasoning on the evidence with their group or partner, along with answering 4 conclusion questions. The teacher will post the correct landmass model key and students will glue their Pangaea into their science notebook. On Day 2, the teacher will read a passage on Alfred Wegener. Students will receive 10 sentence strips from the teacher and will use context clues to sequence the strips to create a timeline representing the historical development of the plate tectonic theory. At this point, the class can have a gallery walk and discuss the event sequence (optional). The lesson will conclude with students answering conclusion questions over the 2-day lesson and writing a summary in their science notebook describing the historical evidence that supports the plate tectonic theory.
