Radioactive Decay Answer Key

activity series review worksheet answer key

A gear ratio is computed as the ratio of the number of teeth on the output gear the follower gear versus the number of teeth on the input gear the drive gear. Answer: Increase the power level output of the motors. Gear Ratio Rules: Challenge students to come up with three rules of gear ratios equal to, less than, or greater than and the value 1 when it comes to pairing different gear sizes. Grade 6 Do you agree with this alignment? We will now see how torque and speed can be controlled using gear ratios. Because all of our content is regularly updated with fresh concepts and designs, you will never lack for ways to keep students of all ages excited about learning.

Alignment agreement: Thanks for your feedback! Give students some time to ponder this question. Transmission Mission: Challenge students to think about the role of transmissions in cars. In other settings, with the same gears arranged differently, larger torque can be produced, such as might be needed for a bulldozer. This makes it an ideal metal to make jewelry from as it will not tarnish or be damaged by chemicals. We can further control the behavior of the transmitted motion by using gears of various sizes, or gear ratios. As we will soon see, certain traits of the machine or vehicle or robot are affected by using correct gear ratios.

Commas or Semicolons Worksheet 2 — Want a reason to celebrate? If you see blank stares, provide some examples of machines that use gears, such as clocks, trucks, robots, etc. Practice with Commas Worksheet — Put commas where they belong. Also called the drive gear. Alternative idea: Ask these questions in the context of bicycle gears instead of car transmissions, which students may find easier to understand. Different types of gears are used in many engineering devices, including wind-up toys, bicycles, cars and non-digital clocks. A worksheet and post-activity quiz verify that students understand the concepts, including the trade-off between torque and speed. What is the definition of speed? They discover how gears work and how they can be used to adjust a vehicle's power.

Online Reading Activities: Complete on phones, tablets, or computers. Activity Embedded Assessment Worksheet Data and Analysis: During the activity, have students use the to record their observations and data. Answer: Use large gear ratios. They then use the information to complete a reactivity series. The increased torque helps a car drive up a steep road by providing increased rotational force to overcome the downward force of gravity.

Grade 6 Do you agree with this alignment? Hence, it is much easier to lift the rock from point D than point C. Last modified: March 18, 2019. Students are introduced to an important engineering element—the gear. Commas or Semicolons Worksheet 1: Determine whether the clauses need to be joined with commas or semicolons. In which machines do we find gears? Students learn about various types of gears and how they work in machines. See Figure 2 for an example final assembly of a Five Minute Bot with its gear trains.

This table is called the reactivity series: The metals at the top are so reactive that they can even set on fire or explode when stored in water. They can use textbooks to fill this in. They also tarnish go dull very quickly when exposed to air. A few of the sentences do not need commas. What remains in the nucleus is reduced in atomic number by 2 because of the loss of the protons, and reduced in overall atomic mass by 4 amu because of the combined loss of those 2 protons and the loss of 2 neutrons which equals that ejected alpha particle.

A gear ratio is less than 1 if the input gear has more teeth than the output gear; this setup is preferred for increasing speed. Provide some guidance in choosing reasonably weighted objects to be pushed. They are introduced to torque, which is a twisting force, and to speed—the two traits of all rotating engines, including mobile robots using gears, bicycles and automobiles. Middle School Lesson Pre-Req Knowledge Students should be able to perform division and have a basic knowledge of ratios and how to reduce fractions to their lowest terms. The answers are provided in the. Gears aligned in certain configurations enable much faster speeds, such as those attained in race cars. Students also get a taste of computer science by using the programmable robot.

Engineering Connection Students are introduced to gears and the mechanical advantages they provide, which are fundamental tools used by mechanical engineers as they design engines for all sorts of purposes. The rate of change of distance with respect to time. The gear ratio is equal to the mechanical advantage of the gear train. Also called the follower gear or driven gear. Have groups choose between placing the small or larger gear as the output gear on their robots, whatever arrangement they think will best configure the gear train for speed, and come up with hypotheses on what effect the gear ratio might make on the speed of their robots. Specifically, they learn how to build the transmission part of a vehicle by designing gear trains with different gear ratios.
