(TN: The teacher may ask each group of learners to discuss those prior knowledge, misconceptions and/or TI which the group previously chose for investigation. This group shall be asked to reason out for either assessing, confirming or rejecting these respectively in the light of the activities conducted and analyses made.)
Provide a variety of differentiated activities
Reactions and Interactions
EXAMPLE 1Ms. Barnes prepared for the lab on simple reactions
between metals and acids. At the conclusion of the experiment, she wanted students to understand that there is a direct relationship between the concentration of an acid and the reaction rate. To help them understand this important direct relationship, she set up different test stations for students to observe. Each station has the same mass of a given metal. Each of the containers held increasing concentrations of HCl. Students had to combine the reactants and analyze the data for trends in the reaction rates.
Recognize that the ability of a reaction to occur and the extent to which it proceeds depends upon the relative stability of the reactants compared to the products and the condition under which the reaction occurs
Reactions and Interactions
EXAMPLE 2Mr. Luther knew at the outset of his chemistry unit on reaction
rates that he had students who not only had different levels of prior knowledge about aspects of chemistry, but also learned more quickly than others in the class. He decided to provide most of his students with a hands-on lab that helped students understand that there is a direct relationship between the concentration of an acid and the reaction rate.
He provided the remaining students with the same metal and solutions as the other group, but invited them to find the ideal conditions for the fastest reaction time.
Recognize that the ability of a reaction to occur and the extent to which it proceeds depends upon the relative stability of the reactants compared to the products and the condition under which the reaction occurs
Greenhouse Effect
Example 1
Mrs. Moore began her week long unit on the Greenhouse Effect and global warming with two journal prompts: What is your definition of global warming? and How does it affect our environment?
Students read, Early Signs of Spring Global Warming (http://www.ucsusa.org/global_warming ) and Mrs. Moore asked questions such as: What is the urban heat-island effect and how does it contribute to our understanding of global warming? In addition, she reviewed the greenhouse effect as well as the enhanced greenhouse effect.
The concluding activity was a simulation and students could choose the membership for their groups. Each group became an organization concerned about global warming and was about to attend a local global warming summit. Each group had to name themselves and come up with a series of strategy statements to better control greenhouse gases. They were invited to use any resources and given the following questions:
What are greenhouse gases? What effects do the gases have on our environment?
What solutions are already in place to restrict the emission of greenhouse gases?
What other solutions would your team like to put into place?
Investigate how the atmosphere is heated from Earth’s surface due to absorption of solar energy, which is reradiated as thermal energy and trapped by selective absorbers.
Greenhouse Effect
Example 2
Ms. Jason began her two week unit with clips from “An Inconvenient Truth” to hook her students into the content of the upcoming lessons and a pre-assessment to determine her students’ background knowledge about this critical contemporary topic.
She spent the next several days explaining –with the aid of her text and visual and audio internet resources – the greenhouse effect and the enhanced greenhouse effect. She used heterogeneous small groups and reciprocal teaching to ensure that students understood these abstract processes. Above-grade level students were invited to find, summarize and post their findings on 3-5 of the most current articles on the impact of global warming. She rotated to the groups to determine misconceptions and ask critical, leading questions.
Investigate how the atmosphere is heated from Earth’s surface due to absorption of solar energy, which is reradiated as thermal energy and trapped by selective absorbers.
Greenhouse Effect
Example 2, continuation
• Mrs. Jason left the last week for a culminating project in which students had to summarize the evidence for/against the role of human activity in global warming. Based on her observations, she assigned students to one of five groups based on their ability to handle abstract, complex material: (1) coral bleaching; (2) warming of the oceans; (3) glacial melting; (4) the relationship among the formation of ozone holes, global warming and greenhouse effect; and (5) the concentration of greenhouse gas over time.
• Each group was responsible for a 5-8 minute presentation to share their evidence and conclusion about the extent of the role of human activity in global warming. Extension for interested students: View “An Inconvenient Truth in its entirety with the following questions in mind: Is there any evidence that Gore’s hypothesis may be “hot air”? (see http:///ww.bbc.co.uk/blogs/today/tomfeilden/2009/09/an-inconvenient _truth_about_gl.html
Investigate how the atmosphere is heated from Earth’s surface due to absorption of solar energy, which is reradiated as thermal energy and trapped by selective absorbers.

Observing Becoming aware of an object or event by using any of the five senses to identify properties
Using one or more of the five senses to gather or collect information about objects and phenomena or events
Looking at a leaf to identify its color, texture, shape, etc.
By observing we learn about the world around us. The information we gain leads to further investigation or use of other processes such as inferring ,communicating, predicting, measuring, and classifying
Activity
Procedure
•Find a partner.
•Ask your partner to get a pen and a scratch paper and let him/her face the back side of this hall.
•Look at the illustration.
PROCEDURE:
•Think about how you might describe this figure to your partner in sufficient details so that he/she could draw it from your description. Your partner will need to know what kind of lines to draw, where to place them, and how long they should be.
•Look at the figure again and keep looking at it for 2 minutes until you perceive it in a way that is different from how you initially perceived it.
•Carefully consider how you will describe the figure to your partner before you begin speaking.
•Without your partner seeing the figure, effectively communicate to him/her how to make lines so that the completed drawing looks as much as like the figure.

Direction: Read and analyze this text carefully.
SKALOOTERS AND DISEASE
Skalooters may enter any part of the body of a larger living thing. When they enter they may rapidly avornate. This often takes place if a greik is weak, tired, poorly fed or injured. As the skalooters grow and reproduce poisonous morogums called tameloses. The skalooter that causes sunatet, muirdiriclos sunateti, is an example. The skalooter is killed by featsure from the air, but produces tantiser naquims which can survive in the soil. If the soil containing these naquims gets into a deep wound where there is no featsure the naquims will cenable and grow. Muirdiriclos sunateti then makes a tamelose which enters the body from the would and causes sunatet. This tamelose is very strong. One gram of the tamelose could kill millions of guinea pigs.
COMMUNICATING involves the use of language of science. When we communicate we consider these three premises:
1.Learning the language of science is a major part (if not the major part ) of science education. Every science lesson is a language lesson.
2. Language is a major barrier (if not the major barrier) to most pupils in learning science.
3. There are many practical strategies which can help to overcome these barriers.

Listing or describing the factors that are thought to, or would influence the rate at which the ice cube melts (eg. Temperature, air movement)
The process of identifying and controlling variables is very important in scientific inquiry. The most definitive results of an investigation are obtained when the variables can be identified and carefully controlled.
Defining variables operationally
Specifying the variables and how they can be measured. They may be specified differently for different investigations.
In studying about the effects of fertilizer on the rate of growth, rate of growth can be defined as the increase in height in mm per week. The amount of fertilizer can be defined as the weight of the fertilizer in mg given to the plant
This skill is very useful in carrying out investigations so that precise data can be obtained

Results of an investigation
A study was conducted to see if the number of surfers on the beach was affected by the average height of waves. It was found out that for average height of 15 waves, there was only one surfer. For an average height of 45 waves, there were two surfers. On the other hand, when the average height of waves reached 75, three were observed to surf. Finally, for an average height of 105 waves, four surfers were observed.

MATERIALS AND METHODS (of the sample experiment)
To determine the effect of horse manure and urea on plant growth and development, 3 garden plots were prepared in school on an area receiving sufficient sunlight the whole day. Thirty sacks of garden soil were bought from Manila Seedlings Bank. The plots (A, B and C), each measuring 150 cm long by 60 cm wide received 10 sacks of garden soil forming an elevation of about 30 cm. Canals were dug around the 3 plots to provide drainage. One kilogram or urea was bought from an agricultural shop while one sack of horse manure was obtained from a stud farm in Los Banos, Laguna. The Bureau of Plant Industry in Manila provided one bag of okra seeds. The plots were watered once a day for a period of 5 days to settle the soil particles.
Meanwhile, seeds of okra seeds were germinated in tray lined with 3 layers of wet absorbent paper. Exactly one week after germination, the seedlings were transplanted in the garden plots.
After another week, seedlings of okra were randomly selected and planted 25 cm apart in 6 rows and 3 columns in plots A, B and C. There were 18 plants per plot or a total of 54 plants per plot or a total of 54 plants in the 3 plots. Since measurements obtained from each plant were likely to vary even if each plot was treated alike, replications in terms of having 18 plants per plot was agreed upon.
To find out how okra seedlings were affected by horse manure and urea, it was decided that plant response be measured in terms of plant height, number of leaves, number of days before flowering starts, number of pods that develops and later, the total weight of the groupos of plants in each of the 3 plants
To enable the seedlings to adjust to environmental conditions, fertilizer was applied on the 4th week. However, before fertilizer treatment, initial measurements of height and leaf counts were done in all three plots. Initial data collected were summarized in a table.
