This is a student check list or guiding questions used to identify the different types of forces acting on an object. Students can ask themselves a question to determine the presence or absence of each type of force, the chart includes clues that student will use to figure out how to draw the given forces, and it also includes an example. LEP Students have found the chart useful since the activity is organized in steps, and it includes visual illustrations.

This simple lab allows the students to practice on the concept of work and power using their own body. Students will calculate the work done when lifting a 500g metal cylinder several times. Students will collect and graph data and determine the power of their hand by determining the slope of the line in the Work vs. time graph.Students then will use the information from the data and the graph to calculate the number of repetitions needed to use the energy equivalent to a hot dog.

Use a ripple tank and a wave generator to measure the speed of a ripple in a ripple tank. Students will be able to set three or more different values of frequency on the wave generator, and them take a picture of the waves produced using a digital camera. with the picture the students can measure the wavelength of the waves, and plot a graph of frequency versus inverse of wavelength. The slope of the line represents the speed of the wave. will the speed of the wave be affected by changes in the

Use frictionless ramps, and and a dynamic cart to test the relationship between the change in the kinetic energy of a system and the work done to stop it. Let the students discover the physics describing the flow of energy on a mechanical system. Use the power of technology to measure the position, velocity, and acceleration of the system and make calculations with precision and accuracy.

There is always a misconception between mass and weight. Are they the same thing or different concepts? In this lab students have the opportunity to explore the relationship between mass (amount of matter) and weight (pull of gravity) and understand the connection between both concepts using simple low tech lab equipment. Students are able to understand why we can use a spring scale to measure the mass of an object.

Students can track the motion of a pull-back car and study its acceleration, Students will plot a velocity - time graph and calculate the acceleration of the car from the slope of the line. Students can measure the uncertainty of the measurements, and calculate the percent error of their experimental result. This lab can be used in high school, or college level.

Give the students the unique possibility to experience hands-on activities to explore heat. Students will perform different experiments illustrating the three heat transfer mechanisms: Conduction, convection, and radiation.

Arduino based project created to collect data during experiments. This document includes instructions to setup the data logger, a list of materials needed, a wire connection diagram, and arduino codes to activate each sensor. The g-code for the box will be submitted after purchase is made, E-mail to ebaute07@gmail.com to send proof of purchase and request the g-code file.

Students will measure the amplitude, period and frequency of traveling waves from a diagram. Students practice calculating the period, frequency, and speed of waves. Students make a venn diagram comparing longitudinal waves to transverse waves.

Students study the motion of a solar powered cart using video analysis. Students will determine the speed of a solar cart from a position vs. time graph, and they will also be able to use the information from the chart to describe the motion. Is the velocity of the solar powered cart constant? How constant the velocity is? A video of the motion is uploaded for the video analysis, and a key is also provided. results may differ depending on the cart used.

In this activity student will use a motion sensor to collect the position of a pull-back toy cart. Students will use the equations of kinematic to determine the acceleration from a velocity vs time graph, or a position vs time graph. Students will use the information obtained to answer the post lab questions. Students also will learn and practice on data collection, and display using data tables and graph.

Use an ammeter and a voltmeter to measure the current and the voltage in several resistors connected in series, and in parallel. Explore how the currents and the voltage are related in each configuration, and use ohm's law and the law of conservation of charge to derive the equations for equivalent resistance in both series and parallel configurations. CPO physics equipment was originally used, but you may use any standard resistors.

Use the law of conservation of momentum to predict the velocity of a ball before it collides with a stationary lab cart. The ball and the cart will stick together and continue to move together after colliding. this lab uses an added part made on a 3D printer. I used a 4.8 cm diameter metal ball from the energy ball kit used for physics. Caution is required when handling heavy objects, do not use open toe shoes and use eye protection.

Use the Arduino uno, and a photoresistor module to make a photogate you can use to measure the speed of a moving object.

Create velocity vs. time graphs using the information from the given position vs. time graphs. The velocity is calculated from the slope of the line in the position vs. time graph.

Practice on solving problems related to conservation of linear momentum for inelastic and elastic collisions, and practice on determining the impulse, and final velocity of a ball bouncing off a wall

Use the HCSR-04 ultrasonic sensor to measure force. Led your students build their own force sensor and learn the principles of sound propagation, and reflection, hook's law, and instruments calibration. Use the sensor made to measure the force in other lab activities. Cultivate creativity, and ingenuity by letting the students make their own designs, using different materials and their own designs. Learn how to use the arduino board to collect data in the physics lab.

Determine the acceleration of a wind-up cart using the arduino uno board and the ultrasonic sensor. The acceleration is calculated from the quadratic fit on the position vs time graph, or from the slope on the velocity vs time graph.

Use an ultrasonic sensor controlled by an Arduino Nano board to measure the speed of sound in air by determining the roundtrip time for an ultrasound wave to travel a pre-determined distance. Use the generic equation for speed to calculate the speed of sound in air. The code for the Arduino, a connection diagram, and sample data are included.

Students will be able to measure the acceleration of a cart down the ramp for different inclination angles, collected data may be used to predict the acceleration of the cart for an angle of 90 degrees by extrapolation. A graph of acceleration vs. sine(angle) should yield a strait line with a slope equals to the free fall acceleration g. A key and student sample data is provided.
