Teacher and Student Resources

This page is under construction! Please check back soon for updates.

We do have a “virtual tour” hosted on Google. It is from several years ago–some areas of the trail look considerably different now–but it is a fun way to visualize the arboretum.

New! We have a virtual tour of the Ethnobotanical Garden now available online, which highlights native and canoe plants in the garden.

Outdoor Circle has a collection of similar tours.

Check out SchoolVirtually, a website that provides resources to support all learners, including students with disabilities and English language learners. It was created by a UH College of Education professor.

Parts of a Plant & What Plants Need to Survive

Parts of a Plant

Parts of a plant

Clickable diagram by DK: Parts of a Plant by DK Find Out

Video: “Parts of a Plant” from the Dr. Binocs Show (approx 3 minutes). Quick introduction to root, stem, leaf, bud, flower, and fruit. (This is slightly different from how we list the six six major parts of the plant here at Lyon. We prefer root, stem, leaf, flower, fruit, and seed.)

Video: “Time-Lapse: Watch Flowers Bloom Before Your Eyes” from National Geographic (approx 3:30). Once you take a close look at a flower, the complexity and beauty can really jump out at you.

Video: “What’s Inside a Bean?” by SciSchow Kids. A bean is a familiar and easy-to-examine example of a seed.

 

 

What Plants Need to Survive

What Plants Need To Survive

Here at Lyon Arboretum, we usually answer the question, “What do plants need to survive?” with four things: light, water, air, and nutrients.

Similarities and Differences…

…between different varieties within the same species

ain’t no party like a Lyon ti party

Similarities and differences within a species

Here at Lyon Arboretum, we have lots of ti (scientific name: Cordyline fruiticosa), and we’re willing to bet you’ve seen it before!

Ti is useful for lots of things, including making ti leaf leis and skirts for hula.

Ti is also really cool because there are lots of kind of ti. The pictures below are all the same kind of plant (ti) but they’re different varieties (kinds) of ti!

 

…between adults and offspring

Similarities and differences between sprouts and adult plants

Koa

The koa tree, which is native to Hawaii, has totally different leaves when it is a baby (seedling) versus when it is an adult.

The “baby leaves” are the true leaves of the tree and they have lots of tiny oval “leaflets” that sit across from each other.

When the koa tree is an adult, its distinctive sickle-shaped leaves (you could also say they look like a crescent moon) appear. These “leaves” are actually the modified stem of the true leaves! Nature is bizarre!

When the trees are in their awkward teenage years, you can see both types of “leaves” on one tree. This website has more pictures and information.

 

Grow your own

One of the easiest ways to observe the similarities and differences between seedlings and adult plants is to plant your own seeds! The first leaves a seed puts out often have a different shape from the leaves the plant will have when it is an adult. Salad greens are especially fun for this because they grow fast and you can eat them when you’re done. Beans are another great seed to use because they are fast-growing and are more likely to be available in a regular grocery store.


2nd Grade (Plants and Friends)

Pollination and seed dispersal

Pollination

Pollination

Resource page: Pollinator Partnership Curriculum


Games for Change: Pollinator Prompt


What is Pollination?” on Eden Project. Features a short (just over 1 minute) video about pollination in the style of an 8-bit video game. Also features a diagram about pollination.

Pollination Facts” on Cool Kid Facts. Has explanations of pollination and related terms for kids. Has some cool examples of pollination pairs, like lemurs and palms and wasps and figs. (Does contain a picture of the seeds of a dandelion, which is more relevant to seed dispersal than pollination.)

Online quiz game: “Parts of a Flower” on Turtle Diary. Type in the names of the flower parts to finish the diagram. Flower parts featured are petal, stigma, style, anther, sepal, and ovule.

Pick the Pollinator Game” on NOVA. A game of matching the pollinators and flowers to each other (online and printable versions are provided). Be sure to check out the answer key, as it expands on each pairing and includes cool information about some of the pollination pairs. Also covers methods of pollination that are less frequently discussed, like water pollination, wind pollination, and self-pollination.

Article: “Bat Role in Pollination,” on Batworlds. A nice summary on the importance of bats in pollination. Also mentions seed dispersal by bats.

Webpage: “Why Bats Matter,” on Bat Conservation Trust. Links to an article about bats as pollinators as well as bats as seed dispersers and reforesters, bats as indicators of biodiversity, and bats as pest controllers.


Video: “Who are Flowers Trying to Seduce?” by MinuteEarth. Topic: pollination and plants (approx 2 minutes)

Video: “Orchids: Masters of Deception” by MinuteEarth. Topic: orchid specializations for survival, including their tendency to trick insects into being unintentional pollinators (approx 4 minutes)

 


Extra material

Article: “Less brilliant flowers still keep bees coming back,” on Science News for Students. Topic: bees seem to prefer flowers that aren’t too shiny, and flowers seem to have evolved to be less flashy as a result.


Seed dispersal

Seed dispersal

Article: “Why do strawberries have their seeds on the outside?” by Matt Shipman, North Carolina State University. 🍓

The Lyon Education Team has many things it likes, and top among those are eating and Wikipedia. If you haven’t perused their list of edible seeds yet, it’s worth doing. When we ask students to name the parts of the plants they’ve eaten, they’re usually most familiar with fruits and vegetables (some of which are, botanically, fruits), and they tend to overlook seeds.

Project Learning Tree: Have Seeds, Will Travel


Blowing In The Wind: Seeds & Fruits Dispersed By Wind. This page is a little technical, but it has many specific examples of wind-dispersed seeds, organized by different types. (E.g., helicopter seeds vs cottony seeds). There are many photos as well! It also features examples from around the world rather than focusing almost exclusively on examples from North America as many classroom resources seem to do.

Here at Lyon Arboretum, we have quite a few wind-dispersed seeds, and not all of them are North American!


Growing with Science Blog: Seed Dispersal

Features good photos, a visual ‘how does this disperse’ quiz, and other cool resources.

Links to three different pages about making your own wind-dispersed “seed” at home. It’s super fun–try it!

Also includes this really cool video about another way seeds can disperse, by “exploding!”


Classes that come to Lyon Arboretum for our 2nd Grade field trip, “Plants and Friends,” get to see and usually hold our double coconut seed (Lodoicea maldivica, also called coco de mer). This article talks about some of the fascinating science behind the double coconut’s survival strategies. “The Secret of the World’s Largest Seed Revealed,” on New Scientist.


Online Game: Seed Racer: an online game from PBS Kids. In this game, the player must collect seeds before they get dispersed by various methods (wind, water, and animals, inside and out). It talks about specific adaptations a seed may have to help it disperse. The examples used will likely be most relevant to students who have lived on the mainland.

Has accompanying teaching tips here.

Watch exploding seeds!

But! There is a cost to plant defenses: https://www.sciencenewsforstudents.org/article/plants-dont-grow-well-when-always-high-alert

Plants may even communicate to each other about nearby predators to tell their neighbors to boost their defenses

Article: “Native Hawaiians Turn to Ancient Traditions to Save Their Reefs” by Yessenia Funes on Gizmodo. There is one error early in the piece (kalo is not native; it is a canoe plant) but it is a great look at how traditional practices continue to provide useful answers to problems today.


Invasive Species

Page: “Albizia FAQs” from the Big Island Invasive Species Committee. Albizia is a highly invasive tree on Oʻahu as well as the Big Island, and the story of Albizia closely linked with the story of our watershed. Learn more about Albizia on this page.

Page: “Strawberry Guava” from the US Forest Service. Strawberry Guava is another highly invasive species in our state.  Not only is it bad for our native forests, it’s also bad for our watershed! Learn more about this tree and one way the state is looking into controlling its spread through biological controls.
