Homework is an area of importance and to make it more relevant for the NCERT Books classes 6th, 7th and 8th, appropriate strategies and meaningful activities may be suggested to the schools that give more time to child to explore the environment to develop creative thinking.

These activities (like OTBA for class 9 & 11 ) would be so framed that they keep the child interested in subjects and therefore would also help in enhancing the learning power. Homework is one of the areas that need urgent attention. As the students of class VI, VII and VIII develop a certain learning style and want to know and find more and more. Efforts should be made to make homework more creative and interesting so that the students do not feel burdensome while doing the same and the ultimate purpose of providing homework is served.

A survey was conducted through questionnaire prepared by CBSE to collect feedback from parents, teachers, students and other educationists on “Alternatives to Homework at Upper Primary Level” for Class Sixth, Seventh and Eighth so that appropriate strategies and meaningful activities can be designed and suggested to schools. The questions were directed to know the ideal quantity and purpose of the homework, whether homework should be assigned in all the subjects, internet usage should be a part of the homework or not, how homework helps in teaching.

Keeping in view emerging issues, there is a need to think about giving quality homework emphasizing on acquiring applied learning skills. Few points can be kept in mind while designing a quality homework by teachers: 1, Provide students capacity building activities which are followed up and acknowledged like drawing, creative writing, making puzzles, stories, plays, online games, reading online books and craft.

2. Provide them assignment sheets which improve their reading & writing abilities. Homework must enable the student to practice a skill independently. 3. A possible discussion can be held with different children on what they would like to do at home to improve in which ever area they deem necessary. Homework must be designed in a way that maximizes the chances of its completion by the students.

4. Parents should be able to understand the child’s needs and schools suggestions on how to learn mathematics, logical reasoning, etc. by doing puzzles, writing letters, reading to elders from the newspapers, making household lists, recipe making and cooking. 5. Learners who have dyslexia or number difficulty should have practice assignments overcoming their problems.

The child in middle school have a keenness to discover more and prepare for the examination. Learning is about developing new faculties, which become useful as an adult. The years 12 to 15 are years when rules become important, and doing well, excelling are given importance both at home and in the class. As the child grows chronically his/her emotional maturity also grows and there are interests which are beyond just what lessons can give.

The homework assigned should: 1. enhance study habits and practice skills (which learners are able to perform independently) 2. reinforce necessary skills both scholastic and co-scholastic among the learners. 3. enable learners to become independent learners and thinkers and develop among them 21st century skills so that they can participate in Make in India in future. 4. lead to the improvement in the academic achievement of the learner.

5. expand on the existing knowledge of the learners and be a part of the already acquired competencies in the classroom. 6. not put unneeded pressure or stress by including new learning material or difficult material to be worked upon by learners themselves. 7. be CBSE Syllabus based and as per developmental needs of the learners. 8. not require specific resources or technology which is not accessible to all learners. 9. have clearly defined, purposeful, creative and engaging activities.

It is also advised that teachers can refer to Life Skills Manuals, Health Manuals and Environmental Education Manuals which contain age appropriate and interesting activities which can be taken up by the learners individually. These activities can be assigned to learners so as to enhance their life skills, values and make them health conscious.

Homework is needed, and necessary for a teacher to be able to follow up with each child. The correction and feedback on homework is an important input that helps both parents and children to follow up and improve in areas which are needed. The recourse extra classes, can be reduced if the homework is used for learning improvement and acquisition of diverse skills. We are providing a handful help to solve or helping in solving the holiday homework.

  • Measure how body temperature and reaction time vary throughout the day
  • Model the human cardiovascular system
  • Use spin tests to discover how your eyes and ears affect your balance and dizziness 
  • Determine how much huddling reduces heat loss in warm-blooded animals

Here are some of the Science Projects for Class 8th Exhibitions that you can try:

The majority of the meals that we take in a day include carbohydrates or sugar. But the form in which we consume them is different and the one that is found inside the human body is different. In our body, glucose is broken down into simpler substances and you can opt for a glucose experiment for your Class 8 science project through which you can analyse the presence of carbohydrates in glucose and our food. As per your choice, collect some food items of daily life along with food dye, room temperature water, plastic glasses, knife and record your observations. You will also need glucose reading strips for this science project and create a positive strip by dipping a glucose strip into a sugar-based or glucose solution as well as a negative strip by dipping a glucose strip into the water. Then, test each of the foods you have taken with these two strips and record your observations. 

Water in its pure form has a specific boiling point and if we keep on adding some solutions or chemicals to water, its boiling point tends to change. For this simple and interesting science project for Class 8, you need some basic household items, i.e. sugar, salt, lemon juice, oil, oranges, jaggery, tea, etc. Ask an adult for supervision and assistance in helping you test the boiling point of water while adding a different item every time. Record your observation for these items and create your Science project accordingly. 

Having a homemade volcano is an amazing science science project. You need to build a cone shaped structure similar to a volcano with a container in the middle. Then in that container, add vinegar. Now, to demonstrate the working of the volcano, add baking soda along with some food colour to the vinegar. The volcano will erupt with effervescence which is generated due to the reaction of baking soda and vinegar thus releasing CO2 gas.

science homework for class 8

The red cabbage that we eat consists of a natural pH indicator that we can use to identify the nature of various substances. Since not many people are aware of this natural indicator, you can use red cabbage to create a unique Science project for Class 8. First, extract the juice of red cabbage and take some paper cups. Now, you need a specific amount of the following items in each paper cup:

  • Baking Soda
  • Lemon Juice

Now, pour the red cabbage juice into each cup until the colour of the liquid/powder [baking soda] changes. Note down your observations regarding the nature of acid and base in each item as indicated by the red cabbage and astonish your class with an amazing science experiment!

Do you know that the potato we use in our food can actually convert chemical energy into electrical energy? As a potato has many nutrients that act as chemicals in a particular setup, it can be used as an electrical battery and thus a unique working model for your Class 8 science project! You need a few potatoes to create your own potato battery and the process is quite simple. Take two potatoes, zinc and copper electrodes, 6 alligator clips and a small bulb/digital clock. First, insert the zinc and copper electrodes in the potatoes and then use alligator clips to attach the electrodes with the clock or bulb [adult supervision necessary].

You will see that the potatoes will charge electrodes and then the clock or the bulb will turn on automatically.

Amongst the most popular science projects for Class 8, you must have come across this one in day-to-day scenarios. Have you noticed that the pan in which we cook gets all heated up including the handles of it or the tong with which we cook our chapatis becomes hot? This is because of thermal conductivity in solids which means that the molecules of solids when heated up move in different directions and spread the heat. For your project, you can pick a bunch of solid items and check at which temperature the entire object gets heated up and up to which temperature.

You must have come across various high-end cameras, but a pinhole camera is something that you can construct from simple household products. The camera does not contain any type of lens rather it is a light-proof box which has a small hole on one of its sides. Light from one side will fall into it and then by using its effort, it will reflect the picture on the other side of it.  the image formed by this lens is inverted, thus,  it becomes a tree basis of your entire project. 

Science Working Model for Class 8

Here is a list of Science Working Models for Class 8:

  • Wind Turbine
  • Biogas plant

Now, let’s pick up some of these and learn how to make these models:

Biodiesel is made from vegetable oil and animal-fat based diesel fuel including long-chain alkyl and esters. Biodiesels are made by chemically reacting lipids, e.g., vegetable oils, animals with alcohol to produce fatty acid esters. The project is for renewable energy, physics, biology.

A telescope is an optical instrument to make observations to make distant objects look closer with an arrangement of lenses or curved mirrors. The rays of light are collected and focus on resulting in magnified images.

A cotton candy machine follows the same framework everywhere in the world and you can make it right at home. When sugar is heated, it becomes liquid caramel. If liquid caramel is pushed through tiny holes to the outside by centrifugal force when the container continuously rotates, cotton candy is made by recrystallization.

One of the most famous working models is the human heart’s working model. The project only requires a physioball, PVC Pipe cap, balloons, and drip pipe. The project will barely take an hour to complete and you will be able to impress your teacher with it.

Drop an egg to prove the first law of motion Assemble a Newton’s cradle Blow out a candle with a balloon Relight a candle without touching it Measure and compare lung capacity

The majority of the meals that we take in a day include carbohydrates or sugar. But the form in which we consume them is different and the one that is found inside the human body is different. In our body, glucose is broken down into simpler substances and you can opt for a glucose experiment for your Class 8 science project through which you can analyse the presence of carbohydrates in glucose and our food.
