Sand

1. Divide the following list into two groups according to how they respond to fire. What is common to each group? Honey Water Sand Plastic Egg Shell Pepper Hair Bread Iron Frames Rubber Sugar Glass Paper Clips Dried Milk Grass Margarine Bone Salt

2. Consider the powders on the table: Sugar, Salt, Pepper, Flour. Which do you think is the odd one out? Explain your answer. After heating the powders up… 2) What happened to each powder on the hot plate? 3) Which is the odd one out this time? Explain.

3. Source Sugar Flour Pepper Salt Sugar Cane Wheat Seeds Pepper Seeds Ocean/lakes In conclusion: Substances that make living things, also burn.

4. What does “burning” mean? A substance that burns, does this: Initial heat Substance + O2CO2 +H2O+heat Since it breaks down to carbon dioxide and water, the substance must contain carbon. ORGANIC substances are made out of C, H, and sometimes O, N, more. Organic substances burn.

5. Organic substances: • In nature, they originate from living organisms. (Today – many are synthetic).

19. Activity: Molecules of Life Models Directions: Read the description on the card. In your notebook and on a blank group paper (size: half a printer paper) draw a brace/arrow map of the terms listed. - ADD DRAWINGS OF THE MODELS. 2. Add your map to the appropriate place in the class’ ‘big map’. C O N P 1 monomer

32. A closer look at the molecules Work with drawings of molecules: 1.Color: Oxygen - Red, Nitrogen – Blue. 2. Cut out the drawings. 3. Title two large papers with the four group of bio-molecules. 4. Paste the molecules according to the slides’ prompts. Are You READY??

33. Four titles on your large paper. Proteins (amino acids) Lipids Carbohydrates (mono- di-saccharides) Nucleic acids (nucleotides)

34. Proteins are made of amino acids. There are 20 different amino acids, but all share the following part: I SPY amino acids! O O N

35. Carbohydrates are made of small sugars, singular or in chains. Small sugars can look like a ring or an open ring: I SPY carbohydrates! O O O O O O O O O O O O O O O O O O O O O O O meet the -oses…

36. Amongst Lipidsfatty acids are long hydrocarbon chains, and several cholesterol-shaped molecules.I SPY lipids! O O O O O O O

37. Nucleic Acids, such as DNA, are made of nucleotides. Nucleotides themselves are rather complex: N N N N N N N O O O O N O O O O I SPY nucleotides and their parts!

39. Analysis: • List the four major types of biomolecules, and for each – name its parts / monomers. • For each type of monomer, name two examples. • For each type of monomer – draw the common part. • Which molecules here are made of more than one subunit? • Which type is the most varied?

41. Observe the molecular models: • What do the marshmallows and toothpicks represent? • 2.How many bonds (connections) doC, O, Nand H always make? • 3. Write at least two facts that describe a parts-whole relationship.

42. A closer look at the molecules Work with drawings of molecules: 1.Color: Oxygen - Red, Nitrogen – Blue. 2. Cut out the drawings. Sort the drawings into FIVE groups. 3. Glue the grouped molecules onto a paper, as organized as you can. 4. Give each group a title.

44. Journal • Observe the food pyramid: • What is the underlying message? • 2. What do you expect to gain from eating each of the food groups? • 3. Proteins, Carbohydrates, Lipids, Nucleic acids: Which food groups provide them? (guess if needed) • 4. Any questions about the pyramid?
