Answer key grade 8 science module

Among the three states of matter, gas has the most scattered molecules. It is followed by liquid while solid appeared to have the most compacted molecular arrangement. Condensation is a process where gas turns into liquid while evaporation does the opposite manner. No, melting is a process that involves convertion of solid state into liquid while freezing is its complete opposite. It solidifies. The change in temperature enable the liquid either absorbed or released heat from its system. If heat is removed, the molecules loses kinetic energy and moves slowly. But if the heat is absorbed it will do the opposite. Either of the two processes happen, the liquid will change its state. Yes, both sets of pictures involve water that changes its state. However it went on the opposite ways. Water vapor turned into liquid. What I Can Do Answer may vary 4.

They too have faults in their land where energy is locked for some time before it is unleashed in devastating earthquakes. In Module 2, the students learned that when work is done on an object, energy is transferred. From here, introductory discussion on factors affecting sound may be included.

The KE is proportional to the square of the speed, thus if the speed is doubled, the KE will be quadrupled. It can also cause changes in some properties of matter such as temperature. This way the students cannot see the mechanism inside the can. The Philippines is located right where tropical cyclones form and there is nothing to do but learn how to survive their annual onslaught. The teacher can make an improvised switch using illustration board and aluminum foil as shown in Figure 3. At this point, students should be made to realize that everything is made up of moving particles. For easier handling, the Fault Model may be pasted on a folder or cardboard before cutting it out. B Additional Activities 1. The refractive index of prism varies with the wavelength or color of the light used. Ask the students to compare what they saw in the activity to what is shown in the picture. Figure 1. The particles are moving fastest in the container with hot water. Grade8 Science Learner's Module Quarters Now, slowly pull the sides of the box covers as shown in Figure 5. Or as the amount of force applied on the cart increases, the acceleration of the cart also increases.

Students can be allowed to use an iron stand with clamp to hold the thermometer to ensure that it will not touch the bottom of the container. We noticed that the lengths of the strips in all the tape charts are in increasing order. The ball slowed down and stopped because an unbalanced force caused it to change its motion. The wavelength decreases from red to violet while the frequency increases from red to violet. References and Links Henderson, Tom. The length and thickness of the conducting wire are factors that affect resistance encountered by current. Unfortunately, this model does not show a crack in the sand that would represent a fault. How are work, energy and power related? What is expected to happen? The students will be able to infer that white light is made up of many different colors of light and each of these colors of light bends differently. The sum of the voltage across each load is equal to the total voltage. In hotter medium or cooler medium? They get their energy from the food they eat. The pen is at rest.
