Unit 1: Growth & Change in Plants
Think you know about Plants?
Try this activity to learn more about the different plant types.
What do plants need to grow?
|
As you can see, plants need different things to grow including water, soil, space, light and air. We have also seen that plants need time. Here is an explanation to help you understand why.

The parts of a flower - Working with animals!
Plants and animals depend on one another to get what they need. Animals use plants for food and to build homes. Animals also help plants. Let's look at the parts of a flower to see how plants and animals interact.
Activity: Take apart a flower.
Activity: Look at the life cycle of a plant to see how animals help with pollination.

Pollination Video
Plant Survival
As we have seen, pollination, the creation of seeds that turn into new plants, allows for plants to reproduce and survive. As we review the next video, let's start to think about the different ways in which pollination occurs.
|
After watching the video, do you understand how pollination occurs? What role does the natural environment play?
Let's read the information on this website to help complete our worksheet. Here is another look at the types of pollinators that will help. |
Pollination and Seed Dispersal
Plant Pollination happens in two main ways: animals such as bees that travel from flower to flower seeking nectar. Flowers that are pollinated by animals or insects are usually colorful, have nectar, and smell nice. Why?
To attract animals or insect pollinators.
Wind Pollination is the other main way that plants pollinate. These plants have small petals and long stamens. The wind carries the pollen from the stamens to the stigma of another plant.
Seed Dispersal
After pollination happens, seeds grow. When they are fully grown they disperse – or go away – from the parent plant.
This happens in three main ways:
1) Animals eat, bury or carry the seeds that are released into soil away from the parent plant.
2) Some fruits and seeds are light enough to be dispersed by wind.
3) Some fruits and seeds "explode" away from the parent plant.

Unit 2: Forces Causing Movement
What is a force? Complete parts 1 and 2 of this activity to help you find out. Do you know what a force is now? Look at this animation for another look.

Types of Forces
Great work finding the different pushing and pulling forces in the four seasons picture. There are many different types of forces, but we are going to look at four different types: gravity, muscular force, buoyancy, and friction.
All planets have forces that pull objects towards them. The earth's gravity force keeps us on the ground! Use the song to help you remember this idea.
Muscular force is a force that results from the action of our muscles. When you looked at the activities in the four seasons picture, many of the push and pull forces happened because of muscular force! Look at the slide show below to think about how the muscles are working to create force.

Here are some explanations from TVO Kids to help you understand how other forces are working together to dribble a basketball, downhill ski, toboggan, and to do gymnastics on a trampoline. If you want to explore buoyancy, look at the picture below. Why do you think the ice cubes don't sink to the botton of the glass?
Gravity and Buoyancy Tug-of-war!
These two forces work against eachother, like a tug-of-war! In this picture, gravity pulls the ice cube down, and buoyancy pushes it back up. Who wins the tug-of-war? This depends on how solid the ice is: the more solid it is, the further down gravity can pull it. If it is less solid, or dense, buoyant force will push it higher!
Try this activity to learn about friction force.
Great work last week boys and girls, let's review some of the basics here.

Push & Pull Forces
Some forces are both push and pull forces. One example is magnetic force. Learn more about magnetic forces in this activity. Try this video for a different look.
Balanced and Unbalanced Forces
Forces cause people and objects to move in different ways, and sometimes to not move at all!. Let's use this activity to investigate how forces cause objects to start moving, stop moving, and change direction.
After your investigation, look at the picture to the left, and the one below: which picture shows balanced forced? How do you know?

Unit 3: Strong & Stable Structures
Structures exist everywhere. Just look around you and you can see different types! There are specific attributes that make up a structure, and also different categories. Strong and stable structures are important for many reasons including safety. Do you think you know what a structure is? How about a strong and stable structure? What types are there? Take a look at the slide show below to see if you can answer some of these questions.
Structures are characterized by their form and function. When structures are created, form and function are important attributes that need to be considered. After reading the bee hive article, can you explain what form and function are?
Forces Acting on Structures
Now that we have an understanding of structures and their form and function, we need to think about the types of forces that act on structures. We can look back to Unit 2 to review important ideas, but we also have to remember that we are now talking about forces that act on structures. We are going to focus on the two shown in the picture.

Unit 4: Soils in the Environment
Since you know about the importance of plants for humans, what can you infer about the importance of soil in our communities? It's only dirt, isn't it?
Want to learn more about soil, including how this frosting is like soil? Just click the picture below.
How important is soil? The links below will help us develop a better understanding.
Excellent discussion today boys and girls, you did a wonderful job using your ideas to show how urban and rural communities use soil. If you want to review, just click the file below to open it.
