This week in science we will continue learning about animal life cycles. We looked inside and uncooked egg and learned what all of those parts are and what they do. We read our textbook and answered questions about what we read. We learned about complete and incomplete metamorphosis this week. We will soon schedule the test on life cycles and send home all of the work we have done on this unit.
As a culminating project we will attempt to hatch chicken eggs. The fertilized eggs are going into the incubator on Tuesday, April 18. During the 21 day incubation period, students will learn about the changes taking place inside of those eggs, and will write entries in their very own Egg to Chick Diaries. These entries will be written from the developing chick’s point of view.
We have finished reading about and working with plant life cycles. Last week, students dissected lima bean seeds. They read about what each of the parts does. We also planted some.
Next, we read about parts of a flower and observed and read about pine cones and conifers.
Study Guide for Life Cycle Test
A cactus is a plant with long roots near the surface of the soil. These roots are one way that the cactus has adapted to a place where there is little water.
An egg is the first stage in a bird’s life cycle.
A butterfly goes through a complete metamorphosis.
The pistil is the part of the flower where the seeds develop.
The role of a flower is to produce seeds.
Wind, water, and animals spread seeds.
The larva of a butterfly is also called a caterpillar.
The part of a seed coat that protects the embryo is called the seed coat.
In the nymph stage, a grasshopper does not fly because it has not grown wings.
When puppies are grow they are in the adult stage of their life cycle.
Laying many eggs is an adaptation to help the species continue or survive.
The egg is the first stage in the life cycle for almost all animals.
Stored food is the food that a plant embryo needs to survive.
Incomplete metamorphosis is the life cycle that a grasshopper goes through.
Pollination is the process by which pollen lands on the pistil to make seeds.
Fruit is the part of the seed that forms around a seed (tomato, for example).
Stamen is the part of the flower that produces pollen.
Petals are brightly colored parts of a flower.
Here is the order of the four stages in the life cycle of a butterfly:
1 – egg, 2 – larva, 3 – pupa, 4 – adult
Forest fires are very dangerous but they can be helpful too. The heat from a fire causes the cones of a lodgepole pine to split open so that the seeds can be scattered.
