Paper Chromatography
This activity introduces the process of paper chromatography and why scientists use it in crime scene investigations. A crime has been committed. It is the students' task to perform a chromatography to identify the killer. Students will separate the pigments from artificial urine samples that w...https://education.ti.com/en/activity/detail/paper-chromatography
Paper Chromatography in Crime Scene Investigations
This activity introduces the process of paper chromatography and why scientists use it in crime scene investigations. A crime has been committed. It is the students; task to perform a chromatography to identify the killer. Students will separate the pigments from artificial urine samples that w...https://education.ti.com/en/activity/detail/paper-chromatography-in-crime-scene-investigations
Electromagnetism
Students use an animated diagram of a magnetic field and a coil. Students rotate the coil and determine the number of magnetic field lines passing through the coil at a given angle. Students graph the relationship and then consider the rate of change of the magnetic field.https://education.ti.com/en/activity/detail/electromagnetism
Electromagnets
In this activity, students will create a solenoid-type electromagnet using two different methods of coiling the wire around the core. They will use a sensor to determine the relationship between the number of turns of wire and the magnetic field strength for each method.https://education.ti.com/en/activity/detail/electromagnets
Vernier - Acids and Bases
In this lesson, students will explore how living organisms can maintain a stable internal pH - even in the event of environmental changes.https://education.ti.com/en/activity/detail/vernier--acids-and-bases
Manipulating Photosynthesis
Photosynthesis may very well be the most important biochemical process in the living world. OK, it IS the most important biochemical process in the living world! In this activity, see how manipulating the amount of light and carbon dioxide can change the photosynthetic production of a plant.https://education.ti.com/en/activity/detail/manipulating-photosynthesis
Vernier - Energy in Food
Students will use the temperature probe to measure temperature changes to measure and compare the energy content of different foods.https://education.ti.com/en/activity/detail/vernier--energy-in-food
Vectors In Component Form
Students experiment with an interactive 2 dimensional vector and observe the corresponding changes to its representation in i and j component form.https://education.ti.com/en/activity/detail/vectors-in-component-form
Water Quality Testing
This water quality project has been designed around a monthly sampling routine for the extent of the project scope. One of the sampling days involved three different classes, each class sampling a different station. This project measured several biotic / abiotic factors to determine the interre...https://education.ti.com/en/activity/detail/water-quality-testing
Fill the Vase
Students interpret graphs of empirical data with respect to rate of change of the height of water in vases of different shapes that are being filled at a constant rate. Students are provided with a range of graphs and vases. For each graph they must reshape the vase in order to match the volume –...https://education.ti.com/en/activity/detail/fill-the-vase
Sweating Alcohol
In this lesson, students will measure and graph the rate at which room-temperature water and alcohol cool as they evaporate. Then, they will draw a conclusion about the rates at which polar and nonpolar liquids evaporate.https://education.ti.com/en/activity/detail/sweating-alcohol
Cellular Respiration
In this activity, students will use a carbon dioxide gas sensor to measure the rate at which non-germinating and germinating peas undergo cellular respiration. Students also investigate the influence of temperature on the rate of cellular respiration.https://education.ti.com/en/activity/detail/cellular-respiration
Intermolecular Forces
In this lesson, students will first observe the changing charge cloud that surrounds a single polar molecule (HCl) and a single non-polar molecule (Cl2).https://education.ti.com/en/activity/detail/intermolecular-forces
Limaçons: A Polar Investigation
This activity allows students to investigate the properties of limaçons in the polar forms of both r =a +b*sin(θ) and r =a+b*cos(θ). Using a slider, values of a and b change as students investigate looped or flattened limaçons, as well as, cardioids. Students examine symmetry and the effect...https://education.ti.com/en/activity/detail/limaçons-a-polar-investigation
Keep It Bottled Up: Linear Rates of Pressure Increase
In this activity, you will see how temperature affects the rate at which an effervescent antacid tablet reacts with water and releases a gas. The rate at which the reaction occurs is measured by the rate of gas production.https://education.ti.com/en/activity/detail/keep-it-bottled-up-linear-rates-of-pressure-increase
Vernier - Boyle's law
The primary objective of this experiment is to determine the relationship between the pressure and volume of a confined gas. The gas we use will be air, and it will be confined in a syringe connected to a Pressure Sensor (see Figure 1). When the volume of the syringe is changed by moving the pist...https://education.ti.com/en/activity/detail/vernier--boyles-law
Properties of Solutions: Electrolytes and Nonelectrolytes
In this lesson, students will use a conductivity probe to measure conductivity and determine which molecules are responsible for conductivity of solutions. Alternative procedure for the Vernier Go Direct® sensors with CXII is included in the downloads.https://education.ti.com/en/activity/detail/properties-of-solutions--electrolytes-and-nonelectrolytes
