Pea Brain!: Explorations in Estimation
Source Institutions
In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
Popsicle Bridge
Source Institutions
In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
Super Soaking Materials
Source Institutions
In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Build a Bridge
Source Institutions
In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.
Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Bury Me Not!
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.
Round, Light and Hollow
Source Institutions
In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.
Round & Round
Source Institutions
In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.
Property Sort
Source Institutions
In this activity, young learners will describe objects by their properties and sort by color, weight and texture. This activity uses household items and toys for materials.
Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.
Fork it Over
Source Institutions
This is an activity about center of gravity. Learners will balance a fork on a glass by finding its center of gravity.
Parachuting Pinwheel
Source Institutions
Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.
Tissue Paper Parachute
Source Institutions
In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.
Flinker
Source Institutions
In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.
Lift Experiment
Source Institutions
In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.
