Good Morning I will check your planners this morning. I will need your “All About Me” poster. In addition any papers you haven’t turned into me with emails, etc. I will also check your journal page 3 and 4 for completion. Morning work and homework for tomorrow is journal page7 and 8. You may work on it now. We will begin with Science in about 15 minutes.
Property Something that you can see like color, texture, or smell.
Bean Pod What do you think you will find inside this pod?
Seeds & Fruit Seed - the part of the fruit that holds the young plant. Fruit - the structure of a slowing plant where the seeds are. Pods are part of the plant that holds the seeds and scientifically we consider these fruits.
Scientific Method Question: How are seeds similar and different in different fruits? Hypothesis: Write down your 4 fruits, how many seeds you think you will find, and draw a picture of what you think the seeds looks like. Conclusion: how does your hypothesis compare with your results
What are the properties of the bean seeds? Are they small or big, round or flat, rough or smooth, hard or soft? Other properties can include size, shape, color texture, or smell.
What was the most common number of seeds found in the pods? If you opened one more pod, how many seeds do you predict you would find inside? What was the most common number of seeds found in the pods? If you opened one more pod, how many seeds do you predict you would find inside? Estimate - how much or many without actually counting. Estimate - how much or many without actually counting.
Notes Where are seeds found? Seeds develop in the fruit of a plant.
Properties With your group discuss the different properties of these seeds such as size, shape, color, and texture.
Seeds Seeds are living plants in a resting or dormant stage. If we wanted to grow these seeds, what would we need? What do you think would happen if we just watered these seeds instead of planting them in the soil? Do you think they would grow? How can we find out?
Scientific Method Question: What will happen to the seeds if we just water them? Hypothesis: what do you think will happen. Conclusion: how does your hypothesis compare with what really happened.
Good Morning Today is a gold day. If you have a stack of papers that are graded on your desk please pass them out. Once you get your graded papers put them in your folder to take home. Jon Fuller please see me. If you have MOOSE bucks on your desk those are from the questionnaire you brought back to me last week. Morning work is to read the Science Story, “ Barbara McClintock” and finish the sheet in your science story book. Please turn it in to me when you are done. IT is for a grade. You will have until 8:20 to complete it.
Draining the Sprouters The sprouters must be drained or they will mold.
Class Sprouter We will use the same water that I have prepared for your sprouters that we will use for the class sprouter. We need to keep one of each seed out of the water to compare back to. We will keep the bean seeds in the top two trays and the rest in the bottom tray.
Notes In what ways does water affect seeds? Seeds will swell up, may change color, smell, or become slippery, and have structures growing on them. What changes do you think you might see in the sprouters after 5 more days?
Questions What could be causing the seeds to appear swollen? If the seeds are soaking up water, how can we find out how much water the seeds are holding?
Balance What are some ways that we could measure the seeds? What should we compare the soaked seed to?
Materials dry Lima beans Soaked Lima beans Balance Gram pieces
Results Does it make a difference where the beans or the gram pieces are placed in the cups? Does it make a difference if the gram pieces are placed gently or dropped into the cups? Weigh them again but this time record the weight on page 6 under day 1. Add water to your bean cup until they are just covered with water.
Scientific Method Question: How much will soaked seeds weigh compared to dry seeds? Hypothesis: what do you think will happen. Conclusion: how does your hypothesis compare with what really happened.
Estimation Estimate how much the beans have swelled. Do you estimate the beans to be the same size, twice as big, or more than twice as big as the dry beans? Now drain the excess water from the beans. Now weigh the soaked beans and record your findings on page 6.
Results Was anyone surprised by the result? Why do you think the seeds soaked up so much water?
Procedure Remove the thin outer coating on the seed. Open the two halves of the seed. Using the hand lens, examine the inside surface of the seed. Share your observations with your group members.
Seed Parts Seed coat - the thin white shell that comes off the seed. Cotyledon - the two halves of the seeds that stores the food and energy for a young plant. Embryo - the structure inside the seed that contains the tiny leaves and root.
Notes Is a seed alive? How can you tell? Yes. Seeds begin to grow and develop when placed in water. What is inside a seed? A seed holds the food for the plant embryo.
