The Learning Activity Sheet is a product of the collaborative efforts of the Schools Division of Cadiz City and DepEd Regional Office VI - Western Visayas through the Curriculum and Learning Management Division (CLMD). This is developed to guide the learning facilitators (teachers, parents, and responsible adults) in helping the learners meet the standards set by the K to 12 Basic Education Curriculum. The Learning Activity Sheet is self-directed instructional materials aimed to guide the learners in accomplishing activities at their own pace and time using the contextualized resources in the community. This will also assist the learners in acquiring lifelong learning skills, knowledge, and attitudes for productivity and employment. For learning facilitator: The Research 1 Activity Sheet will help you facilitate the leaching-learning activities specified in each Most Essential Learning Competency (MELC) with minimal or no face-to-face encounter between you and the learner. This will be made available to the learners with the references/links to ease independent learning. For the learner: The Research 1 Activity Sheet is developed to help you continue learning even if you are not in school. This learning material provides you with meaningful and engaging activities for independent learning. Being an active learner, carefully read and understand the instructions then perform the activities and answer the assessments. This will be returned to your facilitator on the agreed schedule. iii This study source was downloaded by 100000852996565 from CourseHero.com on 01-16-2024 01:29:03 GMT -06:00 https://www.coursehero.com/file/77988180/LAS-RESEARCH-1-Grade-7-MELC-4-Q2-Week-4pdf/ Name of Learner: ____________________________________________________ Grade and Section: ___________________________Date: ___________________ Research 1 ACTIVITY SHEET No. 4 Formulating Hypothesis I. Learning Competency with Code Formulate hypothesis (SSP_RS7_IPS-II-J-12) II. Background Information for Learners A hypothesis is used to describe a phenomenon or foresee a relationship in communication research. The following are the criteria for a hypothesis: must state an expected relationship between variables, testable and falsifiable, able to test whether it is true or false and must be stated as simple and concise as possible. The following are the requirements in formulating a hypothesis: a specific, testable, and predictable statement driven by theoretical guidance and/or prior evidence. In experimental settings, researchers compare two or more groups of research participants to investigate the differences of the research outcomes (Allen, 2017). The fourth stage in the research process is the formulation of the study hypothesis on the basis of the study objectives, particularly the specific ones. A hypothesis is a statement about expected relationships between two or more variables which permit empirical testing. It is also a tentative assertion or proposition whose validity shall be tested in the course of the research. A hypothesis ideally has some basis from the review of related literature. Furthermore, it is described as educated or intelligent guess because its formulation involves critical thinking and decision on the basis of well-thoughtobjectives, research paradigm and review of related literature. Its veracity, whether it is true or not, will be tested using the data that will be gathered. This learning activity will help you to learn about hypothesis and how to formulate it. 1 This study source was downloaded by 100000852996565 from CourseHero.com on 01-16-2024 01:29:03 GMT -06:00 https://www.coursehero.com/file/77988180/LAS-RESEARCH-1-Grade-7-MELC-4-Q2-Week-4pdf/ III. Activity Proper Directions: Read the following concepts and do the activities Major Types of Hypothesis 1. Null Hypothesis • a statement of denial of relationship, difference or an effect. It is usually expressed in the negative form of a statement. • exists when a researcher believes there is no relationship between the two variables, or there is a lack of information to state a scientific hypothesis. This is something to attempt to disprove or discredit. • Examples: ➢ There is no significant difference among the varying ratio of squash seeds and commercial feeds on the weight gain of broiler chicken. ➢ There is no significant difference among the varying ratio of squash seeds and commercial feeds on the performance index of broiler chicken. ➢ There is no significant relationship between the amount of squash seeds and the weight gain of broiler chicken. 2. Alternative Hypothesis • formal affirmative statement predicting a single research outcome. It is the very opposite of what the null hypothesis predicts. • Examples: ➢ There is a significant difference among the varying ratio of squash seeds and commercial feeds on the weight gain of broiler chicken. ➢ There is a significant difference among the varying ratio of squash seeds and commercial feeds on the performance index of broiler chicken. ➢ There is a significant relationship between the amount of squash seeds and the weight gain of broiler chicken. 3. Causal Hypothesis• one which expresses a cause and effect relationship between two or more variables. • it aims to determine if changes in one variable cause changes in another. • Examples: ➢ If the ratio of squash seeds and commercial feeds is varied, then the weight gain of broiler chicken is affected. ➢ If the ratio of squash seeds and commercial feeds is varied, then the performance index of broiler chicken is affected. 2 This study source was downloaded by 100000852996565 from CourseHero.com on 01-16-2024 01:29:03 GMT -06:00 https://www.coursehero.com/file/77988180/LAS-RESEARCH-1-Grade-7-MELC-4-Q2-Week-4pdf/ Tips in Writing Hypothesis ➢ ➢ ➢ ➢ ➢ ➢ It should always be in declarative form. The number of hypothesis depends on the number of research objectives. There may be objectives that need not have hypothesis (descriptive in nature). Like in the objective, hypothesis shows the independent and dependent variables. If there are more than one hypothesis, they should follow the logical flow in writing. It is usually stated in the null form because testing the null hypothesis is easier than the alternative hypothesis. III. Activity Proper Activity 1: If, Then Hypothesis Directions: Use the “if, then” type and include a measurable prediction For example: Salt in soil may affect plant growth. If salt is put in soil, then it may affect plant growth. 1. Temperature may cause leaves to change color. ____________________________________________________________ 2. Sunlight causes fruit to ripen more quickly. ____________________________________________________________ 3. Plant growth may be affected by the color of the light. ____________________________________________________________ 4. Bacterial growth may be affected by temperature. ____________________________________________________________ 5. Ultra violet light may cause skin cancer ____________________________________________________________ Activity 2: Writing Hypothesis Directions: Write the null, alternative and causal (if, then) hypothesis based on the problem “What is the effect of varying temperature of water on the dissolving time of sugar?” Fill in the table below.

If salt is put in soil, then it may affect plant growth. 2. If temperature is raised or cooled, then it may cause leaves to change color. 3. If there is the presence of sunlight, then it causes fruit to ripen more quickly. 4. If the color of the light changes, then plant growth may be affected. 5. If temperature changes, then bacterial growth may be affected. 6. If ultra violet light touches your skin, then it may cause skin cancer. Activity 2 Exercise 1 “What is the effect of varying temperature of water on the dissolving time of sugar?” Null Hypothesis Alternative Hypothesis There is no effect on the varying temperature of water on the dissolving time of sugar. There is an effect on the varying temperature of water on the dissolving time of sugar. Causal (if, then) Hypothesis If temperature of water varies, then it affects the dissolving time of sugar.
